hi guys, u may think this is a noob question, but i have hit the power wall. i would like to get some more power out of my r33 gtst. atm it has an upgraded t4 turbo, ssq bov, 720cc injectors (dont ask, dont know why they work), Bilstein heavy duty suspension, front and rear strut bars, nitrided crank, fmic, 3" exhaust and im probably forgetting something.

the turbo will soon be upgraded, a screamer pipe, safc and a tune/remap are on the way. i am also thinking about a z32 afm.

i would like to know from your experience and expertise, whether there are any good mods i can do with a budget, to gain more power, atm the clutch can handle 420kw.

i am probably pushing 190-220kw, which is just a guess atm, will know more after dyno.

furthermore i am thinking of investing in its support systems later on

any and every piece of advice is appreciated thanks.

:):)

How are you running 720cc injectors without management?

You dont have management listed as a current mod, only a future one... so 720's = impossible :)

And i also dont get a nitrided crank either!

For basic mods, see here:

For more results, so you can relate that to parts

http://www.skylinesaustralia.com/forums/in...showtopic=55845

There are but a small few of the good threads you can find :)

Also setting a budget for everything helps to get more accurate responses

cheers all the mods bar the fmic and strut braces have been done by previous owner. ive only had car since january.

i will definitely check out ur links, budget is about $3000

You could have made 200rw will stock turbo and stock injectors - sounds like what you need is a power fc or somesort of full engine managment to get what you have running properly and efficiently.

thanks heaps, the responses i have been getting is to invest in electronic support systems.

i will definitely have a look around.

no, its a 5sp manual

thx

Yeh definatelly get an ecu and if you can the power fc is probably your best bet - hard to find nowadays though. That way you can tune it and make the most of your bigger turbo and injectors - should have nice power then. :)

Stock turbo

3" turbo back exhaust

Intercooler

Fuel pump (eg: bosch 040)

and something like 12psi should get you anything between 190rwkw-210rwkw depending.

It wouldn't hurt to get an SAFC II, fuel only computer, to keep the fuel at a safe level and AFR down to a safe level.

With a tune on the dyno you can push over 200rwkw+ on stanard ECU running the above + SAFCII.

But depends how much you want to spend. Since you already have a T04, get a fuel pump, and an after market ECU and get it tuned. You will make some good power.

Hope that helps.

Thanks,

Abu

definitely thanks. thats perfect i want to have about 250kw if possible, and maybe more, just to beat a few mates.

at least on this forum i can listen to people that have done it before, some engineers i have questioned dont know shit about imports.

once again thanks, i will look around for a better ecu/ power fc and a fuel pump.

I still dont understand how you have 720cc injectors with a stock ECU

theres alot you may not understand, but it works and thats all i care about, that is one of the reasons i purchased this particular car.

all those extras with no ecu upgrade.....

you should be upgrading ecu if u go down the bigger turbo/bigger injectors road.....

yea, ive been thinking about it for a while, im just waiting for a good unit to come onto the market.

I know enough to know 720cc + stock ECU = no chance

:laughing-smiley-014:

Yeh doesn't make much sense, any sense really, even with a simple fuel computer they would flow way too much and the ammount of correction applied would be astronomical. Perhaps either they are not 720cc or it has some crazy re-mapped jap ecu that he is not aware of...

hey guys, just throwing it out there,

does anynone know a ball park figure for a full tune?

any suggestions would be helpful

Depends what your tuning...

safc around 150 -200

Power fc around 400 - 500 perhaps, each car / ecu is different.

I'm contemplating a power fc or if i can't find one maybe I'll go with emanage ultimate. :) safc has gotten me to 195rw so far so its doing an alright job on a reasonably safe tune i.e between 11.5 and 12 afr. :)

Depends what your tuning...

safc around 150 -200

Power fc around 400 - 500 perhaps, each car / ecu is different.

k sweet, i'll tell a few mates, also-im talking too much

but when i get all these mods done, will it be safe to drive around for 1-2 wks untuned. until it is tuned?

cheers

    • I did end up getting it sorted, as GTSBoy said, there was a corroded connection and wire that needed to be replaced. I ended up taking out the light assembly, giving everything a good clean and re-soldered the old joints, and it came out good.
    • Wow, thanks for your help guys 🙏. I really appreciate it. Thanks @Rezz, if i fail finding any new or used, full or partial set of original Stage carpets i will come back to you for sure 😉 Explenation is right there, i just missed it 🤦‍♂️. Thanks for pointing out. @soviet_merlin in the meantime, I received a reply from nengun, and i quote: "Thanks for your message and interest in Nengun. KG4900 is for the full set of floor mats, while KG4911 is only the Driver's Floor Mat. FR, RH means Front Right Hand Side. All the Full Set options are now discontinued. However, the Driver's Floor Mat options are still available according to the latest information available to us. We do not know what the differences would be, but if you only want the one mat, we can certainly see what we can find out for you". Interesting. It seems they still have some "new old stock" that Duncan mentioned 🤔. I wonder if they can provide any photos......And i also just realized that amayama have G4900 sets. I'm tempted 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!
