Morning Fellas,

This is a bit of a long story so be patiant with me......

About 5 months ago, I approached a business in Canberra (I don't want to mention who as I am not the type of person to discredit someone for a bad experience) to build me a RB30 short block, port and polish my RB25 head, fit it all up with my GT35R 0.82 A/R turbo, fit my plazmaman plennum, and tune it.

When I first asked the tuner, before I took out a $16,000 loan to do all this, I asked "how much will this cost from A-Z"? he replied "Around 15 - 17K at the most, won't be anywhere near 20K"

I asked him, "how long is this going to take?" he replied "About 3 weeks for the engine build, and 3 weeks to fit and tune everything".

I further asked him, "I want to make around the 370 rwkw mark, will my computer and injectors be enough for this? he replied "Yep, it'll all be fine, done worry"

FYI, I got a R33 GTS-T with 555cc nismo injectors, running a power FC with a Z32 AFM, 256 - 264 cams with cam gears, Bosch 040 fuel pump etc etc etc.

5 months later the car was finally finished and I got my final tune done yesterday. It barely pulled off 311 rwkw.

To date, I've already speant over $22,000 for this build and tune, FAR from what the estimate price was.

And on top of that, the tuner said yesterday "Oh, your AFM is maxed out, you'll need a new computer, which will cost about $2,400 not fitted or tunned, and you'll need 740 cc injectors"

And by this stage, I was very pissed off because he informed me, before I ever started this project, that my computer and injectors will hold up.

Not to mention that I was already $5,000 over budget!!!! and he wanted me to for out another $2,400 for the computer not even fitted and $900 for injectors!! Not to mention the tune...

For this reason, I told him openly over the phone yesterday, "this process has been nothing but broken promises". He chucked the shits, and hung up on me.

What do you fellas suggest I do?? I cant keep affording to pay this much money, I wont have money to feed me and my family if it keeps going at this rate.....

So now, I am stuck with a 310 rwkw car, and I've paid him over $22,000. Do I take it to another tuner here in Canberra? Should I go see a lawyer?

I feel ripped off and deceived.... $22,000 to get a RB30 block with firged everything, ported head, plennum and turbo fitted up, few parts here and there like oil catch can, hoses etc + labour for $22,000? DOesn't that sound like a bit too much?

Shit, I couldve sold my car for like $10,000 and could've bought a modified R33 GTR for $32,000....

Please give me some suggestions fellas.........

Sorry to hear about that mate. Nothing worse then dumping a whole lot of money into a project and at the end you dont get the desired result! Big let down!

I dont have the solution unfortunately, but if you could perhaps list exactly, part by part of what was done by the workshop so we can see and work out how much it should of cost. It might give a fair idea of how much parts were and labour and whatnot to see if the amount spent equals the amount of work/parts done/supplied.

Without knowing all of it in exact detail, to achieve the power you wanted you would of definitely needed bigger injectors and atleast a q45 afm. The powerfc can handle it fine. I dont know why he wants you to upgrade the computer?!?!

I have just done a 2530 build for a guy. It didnt't include injectors, ECU or tuning and his bill is just over $14k. I don't think the guy is necessarily ripping you off, I think maybe he just might lack the experience to quote the job properly. We all make mistakes now and then when quoting things but it all comes down to talking with the customer about those extra costs and being able to explain why they are more or whatever. Not the fact that he said it will cost $15k and you end up paying $20k. He may not be entirely at fault and I'm sure if there was a third party looking in from the outside, he may pick at some things you have done or said during the build.

I'm not exactly sure but I'm just saying that sure, he may have forgotten to quote for various things but there is sometimes input from the customer which can be reasons why he wouldn't quote the full amount. Did you already have the injectors before the build started? From the builds I have done and others I have seen, it is usually very difficult to get up around the 370rwkw mark on an AFM but can still be done. 550cc injectors should see you to 400rwkw. There could be another reason for it not making the power like fuel pump or maybe the tune is not 100%, who knows.

You need to be running around 26psi to get to 370rwkw on that turbo providing you have the right setup on the head etc.

Hi fellas,

Attached are the following invoices:

1) From the engine builder (however, I still went through my tuner to get this done)

2) Invoice from the tuner

Please note that I didn't attach the last invoice (yesterday's one) which costed me $880 for the tune and fitment and supply of an oil catch can.

I really feel for you. A lot of us hear have been through the same thing. At least yours is still in one piece. I think "Cubes" might be able to give some advice as he has done well with his combination. Looks to me like you will need a bigger exhaust housing. Not a serious problem. Quite cheap really. Injectors I think for sure. 370kws needs to be fed.

How many Rb's has he built ? Maybe he just hasn't done an RB30 before. Five months sounds about right. It is always funny when you ask a builder how long and he looks you straight in the eyes and says, "yep, that will be three weeks". That's usually when you walk away. There are guys on here that can actually do it in 6 weeks but you would have to confirm with them.

I remember a 55' Chevy I had and was getting an engine built for it. I think the promise was a month. 4 months later I pulled into his workshop with a crate motor from the states and told him to have it running by the end of the week. My old engine was still sitting on his engine stand with the carby, dizzy,headers, everything. It hadn't been touched in 4 months. Threats were made let me tell you.

Hi mate, I already had my 555cc nismo injectors, I already had a Boosch 040 fuel pump.

There is no problem with the fuel, the tuner called me and said the AFM has maxed out, and he didn't want to tune it anything past that unless I get a new computer (which is fair enough I guess, I guess he doesnt want to damage my engine).

As for the fuel, he then said, if I want to make 370 rwkw, I would have to either get a Fuel Pressure Regulator or 740cc injectors.

The whole problem is, had I known I would have to fork out another $2,400 for a new computer, $400 to wire it up, and another $600 to tune it, I would never have gone through with the project, I wouldve just purchased a modified GTR.

Not to mention that I am already a few K over my budget........

At the end of the day, I am not that knowledgable in what needs to be put together for the build.

If my tuner/mechanic says 15-17K, I expect it to be around there, and not have to fork out $22K plus after.....

Uhhhhhhhhhhhhhhhhhhhhhhhhhhhhh how am I supposed to eat tonight, I am broke as a joke........... :verymad:

Looking at the quote i know who done the work. :verymad:

Hi mate, please keep that info to yourself, I don't want to discredit the tuner's business because of the bad experience I had.

I guess this should serve me a lesson, next time I get a quote, I should get it in writing, not just verbal......

Cheers

You also have a bosch 040 as far as i was aware that wont provide enough fuel for 370kw.

Looking at the quote i know who done the work. :verymad:

I have personally delt with one of the parties and know of others that have delt with both without any issues.

I have gone over the figures in those invoices and I can tell you now you need to pick up the phone, ring your tuner and thank him at least 10 times for looking after you so much on this build.

There are a couple of things that I would say are slightly over the norm but they are only small things. He has only charged you 10 hours on the porting, he has only charged you $1100 to assemble the engine (which is cheap as all shit if you consider the work that goes into it inc. cleaning etc.)

He has basically remodelled your entire car, not just built you an engine and tuned it. There is modifications to the exhaust, a manifold, an alternator, etc, etc.

The truth is, you can spend $15k and get your engine, and get it tuned for 370rwkw but it won't be reliable.

And your pump is an 040 as stated above - only good for max 320rwkw and that's pushing it IMO.

Hi mate,

I am not worried about the engine build (actually, I was happy to pay a premium because I've heard excellent things about the builder).

By looking at the tuner invoices, it makes sense how it's amounted to that total, I am not saying it doesn't.

My issue is that I was quoted for something to be done, and it was alot more, and I still haven't gotten the power that I was assured I would get. Not only that, the tuner wants me to spend more money....

Oh, and my alternator was fine when I drove the car in, 2 months later and I get a call from the tuner saying my alternator is faulty...

I couldn't help but think, it was fine when I drove it in there.................. Nonetheless, I sucked it up and paid for it.

The prices seem to be fairly right.

The only reason why this thing hasnt gone to plan is because the mechanic underquoted, which is mostly his fault, probably lack of experience with these things, BUT sometimes things go wrong and take way longer to do.

Modify Manifold: He wouldnt have quoted for this at all. Things like that bump up the price. Stupid little things that take hours.

It seems his knowledge is poor as he thinks a 040 can handle 370kw, and that the PFC isnt up to the task, which it certainly is. 550 injectors are definetly cutting it close fuel wise too. He is right to suggest ~700 injectors, but you would expect that he would have known this before even starting.

No point saying 'it only made 310' because the supporting mods arent there...yet. It will make the power in due time.

Dues this mechanic work on skylines all the time, more to the point highly modified examples? Sounds like a V8 mechanic trying to work on Skylines scenario.

Yes, he works on many modified japanese cars, he is a top bloke, I am just pissed off that the end price is MUCH more than the original quote......

I guess there is no point dwelling on what's happened ey?

Im trying to stay positive about all of this....

So, so far I need (please tell me if the prices are sort of correct):

1) 740cc injectors; (About $890 + $100 fitment?)

2) Bosch 044 fuel pump ($290 + $150 fitment?)

3) Computer? What should I get? Maybe Illl have to do a bit more research on this, see who can tune what here in canberra....

I can see another $5,000 being blown just on the three things above with a tune....

Cheers fellas

It happened to me a few times too.

When someone asks for a quick "how much is it going to cost?", my reply is always to say that without sitting down and working it out it's roughly $XXXX.

I prefer to sit down and work things out but now I have learned to overestimate the cost by 20% when answering verbally to avoid disappointment simply because I don't like to let people down.

I don't know the guy but I'm sure he didn't mean to stuff you around man. Hopefully a little lesson learned on both sides here which is to sit down and work it out to avoid disappointment.

Good luck with the rest of the build.

It seems his knowledge is poor as he thinks a 040 can handle 370kw, and that the PFC isnt up to the task, which it certainly is.

I don't think he meant the computer itself isn't up to the task, I think he meant a computer with an AFM isn't up to the task.

Most AFM's max out at 5V, so you can only do a "dodgey" tune so to say after a certain power figure.

This will be risky and I could have alot of detonation on a hot day or is something goes wrong, which could potentially damage the engine.

I think he is hesitant to do this because of the risk associated with doing so, that's why I think he's saying getting a new computer.

Maybe I could get away with just finding a larger AFM? I've heard the Z32 is better than the Q48 (or what ever it's called) because it has a bigger resolution of something?

Why do you need to budget for a new computer? nothing wrong with a PFC.

but you probably need bigger AFM.

Well, I've got a Z32 at the moment, and rumor has it that it's probably the best AFM you can get?

I started a little thread here a little while back about where I can get a bigger AFM, like the Q48, but people advised me to stick to the Z32 as it has a larger resolution (got no idea what that means)?

CHeers

Your almost there mate. Get some sard 850cc injecotrs and a bosch 044 from slide. I would have thought the z32 would be up to the task, if not i am sure someone here with will no what to get and where to get it.

Unfortunately the mechanic has underestimated the project. Pretty common though.

Good luck and i am sure you will get your desired power figure soon. I am sure the tuner will probably do the extra tuning for free too

    • Any update on this one? did you manage to get it fixed?    i'm having the same issue with my r34 and i believe its to do with the smart entry (keyless) control module but cant be sure without forking out to get a replacement  
    • So this being my first contribution to the SAU forums, I'd like to present and show how I had to solve probably one of the most annoying fixes on any car I've owned: replacing a speedometer (or "speedo") sensor on my newly acquired Series 1 Stagea 260RS Autech Version. I'm simply documenting how I went about to fix this issue, and as I understand it is relatively rare to happen to this generation of cars, it is a gigantic PITA so I hope this helps serve as reference to anyone else who may encounter this issue. NOTE: Although I say this is meant for the 260RS, because the gearbox/drivetrain is shared with the R33 GTR with the 5-speed manual, the application should be exactly the same. Background So after driving my new-to-me Stagea for about 1500km, one night while driving home the speedometer and odometer suddenly stopped working. No clunking noise, no indication something was broken, the speedometer would just stop reading anything and the odometer stopped going up. This is a huge worry for me, because my car is relatively low mileage (only 45k km when purchased) so although I plan to own the car for a long time, a mismatched odometer reading would be hugely detrimental to resale should the day come to sell the car. Thankfully this only occurred a mile or two from home so it wasn't extremely significant. Also, the OCD part of me would be extremely irked if the numbers that showed on my dash doesn't match the actual ageing of the car. Diagnosing I had been in communication with the well renown GTR shop in the USA, U.P.garage up near University Point in Washington state. After some back and forth they said it could be one of two things: 1) The speedometer sensor that goes into the transfer case is broken 2) The actual cluster has a component that went kaput. They said this is common in older Nissan gauge clusters and that would indicate a rebuild is necessary. As I tried to figure out if it was problem #1, I resolved problem #2 by sending my cluster over to Relentless Motorsports in Dallas, TX, whom is local to me and does cluster and ECU rebuilds. He is a one man operation who meticulously replaces every chip, resistor, capacitor, and electronic component on the PCB's on a wide variety of classic and modern cars. His specialty is Lexus and Toyota, but he came highly recommended by Erik of U.P.garage since he does the rebuilds for them on GTR clusters.  For those that don't know, on R32 and R33 GTR gearboxes, the speedometer sensor is mounted in the transfer case and is purely an analog mini "generator" (opposite of an alternator essentially). Based on the speed the sensor spins it generates an AC sine wave voltage up to 5V, and sends that via two wires up to the cluster which then interprets it via the speedometer dial. The signal does NOT go to the ECU first, the wiring goes to the cluster first then the ECU after (or so I'm told).  Problems/Roadblocks I first removed the part from the car on the underside of the transfer case (drain your transfer case fluid/ATF first, guess who found out that the hard way?), and noted the transfer case fluid was EXTREMELY black, most likely never changed on my car. When attempting to turn the gears it felt extremely gritty, as if something was binding the shaft from rotating properly. I got absolutely no voltage reading out of the sensor no matter how fast I turned the shaft. After having to reflow the solder on my AFM sensors based on another SAU guide here, I attempted to disassemble the silicone seal on the back of the sensor to see what happened inside the sensor; turns out, it basically disintegrated itself. Wonderful. Not only had the electrical components destroyed themselves, the magnetic portion on what I thought was on the shaft also chipped and was broken. Solution So solution: find a spare part right? Wrong. Nissan has long discontinued the proper sensor part number 32702-21U19, and it is no longer obtainable either through Nissan NSA or Nissan Japan. I was SOL without proper speed or mileage readings unless I figured out a way to replace this sensor. After tons of Googling and searching on SAU, I found that there IS however a sensor that looks almost exactly like the R33/260RS one: a sensor meant for the R33/R34 GTT and GTS-T with the 5 speed manual. The part number was 25010-21U00, and the body, plug, and shaft all looked exactly the same. The gear was different at the end, but knowing the sensor's gear is held on with a circlip, I figured I could just order the part and swap the gears. Cue me ordering a new part from JustJap down in Kirrawee, NSW, then waiting almost 3 weeks for shipping and customs clearing. The part finally arrives and what did I find? The freaking shaft lengths don't match. $&%* I discussed with Erik how to proceed, and figuring that I basically destroyed the sensor trying to get the shaft out of the damaged sensor from my car. we deemed it too dangerous to try and attempt to swap shafts to the correct length. I had to find a local CNC machinist to help me cut and notch down the shaft. After tons of frantic calling on a Friday afternoon, I managed to get hold of someone and he said he'd be able to do it over half a week. I sent him photos and had him take measurements to match not only the correct length and notch fitment, but also a groove to machine out to hold the retentive circlip. And the end result? *chef's kiss* Perfect. Since I didn't have pliers with me when I picked up the items, I tested the old gear and circlip on. Perfect fit. After that it was simply swapping out the plug bracket to the new sensor, mount it on the transfer case, refill with ATF/Nissan Matic Fluid D, then test out function. Thankfully with the rebuilt cluster and the new sensor, both the speedometer and odometer and now working properly!   And there you have it. About 5-6 weeks of headaches wrapped up in a 15 minute photo essay. As I was told it is rare for sensors of this generation to die so dramatically, but you never know what could go wrong with a 25+ year old car. I HOPE that no one else has to go through this problem like I did, so with my take on a solution I hope it helps others who may encounter this issue in the future. For the TL;DR: 1) Sensor breaks. 2) Find a replacement GTT/GTS-T sensor. 3) Find a CNC machinist to have you cut it down to proper specs. 4) Reinstall then pray to the JDM gods.   Hope this guide/story helps anyone else encountering this problem!

    • perhaps i should have mentioned, I plugged the unit in before i handed over to the electronics repair shop to see what damaged had been caused and the unit worked (ac controls, rear demister etc) bar the lights behind the lcd. i would assume that the diode was only to control lighting and didnt harm anything else i got the unit back from the electronics repair shop and all is well (to a point). The lights are back on and ac controls are working. im still paranoid as i beleive the repairer just put in any zener diode he could find and admitted asking chatgpt if its compatible   i do however have another issue... sometimes when i turn the ignition on, the climate control unit now goes through a diagnostics procedure which normally occurs when you disconnect and reconnect but this may be due to the below   to top everything off, and feel free to shoot me as im just about to do it myself anyway, while i was checking the newly repaired board by plugging in the climate control unit bare without the housing, i believe i may have shorted it on the headunit surround. Climate control unit still works but now the keyless entry doesnt work along with the dome light not turning on when you open the door. to add to this tricky situation, when you start the car and remove the key ( i have a turbo timer so car remains on) the keyless entry works. the dome light also works when you switch to the on position. fuses were checked and all ok ive deduced that the short somehow has messed with the smart entry control module as that is what controls the keyless entry and dome light on door opening   you guys wouldnt happen to have any experience with that topic lmao... im only laughing as its all i can do right now my self diagnosed adhd always gets me in a situation as i have no patience and want to get everything done in shortest amount of time as possible often ignoring crucial steps such as disconnecting battery when stuffing around with electronics or even placing a simple rag over the metallic headunit surround when placing a live pcb board on top of it   FML
    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...
