um no i dont have one really that i could lend you but you can just go buy one make sure it has a warranty then if you swap it over and the prob is still there just take it back and say its faulty.im not 100% sure if they can be electroncally tested maybe someone on here knows.but yeah good suggestion is to advance it first and see how you go.

thanks for the info, i think i will try a differnet cas and see if that fixes anything. its worth a try i guess.

just a quick question, is it that the car is just plain slow, or is it a start/stop/start/stop type of thing?

No its a start then stop thing. The tubo spools as normal but car serverley hisitates, almost undrivable, cant really take it over 2.5-3k

I dropped it into F.I.S.T. performance as they are local and one of the few workshops open today and the only works shop who would take the car with such little notice.

So fingers crossed i get it sorted and i will report back as to what the problem is.

I have found other posts with similar issues to what i experience but when they get it fixed no body reports how they fixed it :(

Hey guys! got it back from FIST performace, guys there where great very knowledgable.

Okay when it came in on the dyno it made 128rwhp.

List of things fixed.

- I had a busted fuel pressure regulator

- MY airflow meter was no good!! i tried 2 sensors previously and also resoldered one but that didnt solve it.

- Timming, The cas seems to be in a very advanced position, Tuner said for some reason this car needed a lot of timing to do anything. I know the car has had a rebuild from previous owner with pistons but thats all i know.

- boost 11psi

When it was sorted on the dyno it ran 270.9 RWHP or 202.1 RWKW.

Air fuel ratio varied from about 11.8 - 10. Tuner said it still runs very rich.

I have a SAFC neo comming so that should help things in that respect.

Does any one know why my car needs more timing than a normal r33?

And what do you guys think about the power figures? any thoughts?

Total aftermaket mods to this stage are,

- pod filter

- metal intake pipe

- walbro fuel pump

- FMIC delta fin style. piping is hybrid copy.

- dual stage turbo xs boost controller(low 9psi- high 11psi)

- GFB BOV switchable plumb back type.

Thanks for every ones ideas on this thread!

Are the Cams different?

Thats good power for 11psi.

It was more than just one thing wrong, no wonder you couldnt get it right.

I pretty happy :P

As far as i know the cams are stock, The previous owner claimed a rebuild and showed me some photocopy of a trade reciept for acl pistons but npothing else so i am doubtful if it is legit.

The Timing belt was changed a few months ago.

"R33S2" are u asking if the cams are differnet because the CAS seems to be in the far advanced position? im curious as to why this is too?

Yeah two things wrong makes it hard to diagnose, expecially when i ruled out airflow meter my trying two and resoldering one.

Cheers

it can mean a few things, aftermarket cams, timing belt fitted right??, qoute me if i'm wrong guys.

Check your Timing Belt Tensioner, they are a spring loaded mechanism from what i remember, if its broken timing belt could be far from taught and the reason you need to run spastic timing, if the covers are on your tuner wouldnt have seen shit.

Good to hear you got it sorted :P

Not surprised the AFM was a problem, but it's quite rare for the stock fuel pressure reg to die in my (limited) experience. I suppose they're not getting any younger so things are going to start playing up.

Dunno about the timing thing - maybe the cams have been timed, ie one or both have been advanced or retarded, so compared to where the CAS normally sits it might be a degree or two out. I'm probably completely off the mark but that's my best guess :rofl:

Your not wrong about these cars not getting any younger,

If it is the timing belt pretensioners woulnd they maybe casue the belt to slip? some times at idle there is a wirring sort of squiggle noise from the cas area. The cas bearings are fine so it may be a pretentioner?

Edited by tmc_2

maybe the timing belt has jumped a tooth on 1 of the cams. how many k's on the car (in total, not just since rebuild). it may be that when the engine was rebuilt they didn't replace the timing belt, and it is due to be changed.

my mates 180sx that is having similar problems is overdue for its second timing belt (its done over 200,000ks). we have to keep the timing fully advanced to get it to perform. we tried jumping a tooth with the cas and it was way too advanced. we think the timing belt may have jumped a tooth.

total kays are 125thou , timming belt done at 117thou and rebuild i am gussing some where between 90 to 110thou.

SO u htink its worth getting then to check the timming belt is its alligned correctly?

Will it be fine to just leave alone?

thans Mad082

so u've still got the stock ecu? prolly best to get a power fc (or other) and get it tuned properly. i.e lean it out a bit, then you'll also be able to pull some timing out. it'll go harder, and it wont chew as much fuel >_<

    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
