hey, sorry don't want to steal your thread mate but isn't the stock boost in an r34 gtt up round 11-12 psi? mine is running with no mods and the in car gauge is up there...

is your by anychance a series 2 ? my gtt sedan is !!

there is harm in replacing the hose . you might replace the one with the restrictor in it with a hose without the restrictor in it . =free boost .

anyone who is using the stock gauge can stop replying right now .

my stagea (neo motor) ran an unstable .8 bar with exhaust and intercooler upgrades . all this is common info .

the r34 does have a solenoid . i really dont know how this thread managed to dig up so many uneducated people all at once

as for the spool up its either the normal neo noise ( to do with plastic wheels) or you most likely have a slightly blown exhaust manifold gasket

ok yes my mates car is not a neo but its the only one to go by.

as for the hose before i do try getting a new one is it the one that goes from the T piece under the airbox snorkel and down to the round metal thing just ubove the turbo ?

if so what should i ask for when i go to replace it ? can it be purchased from autobarn?

would the exhaust manifold gasket leave some evidence if its leaking? iv looked and theres no oil or moister (u use to race a gemini in rally and thats how i could tell if there was a manafold leak if it wasnt obvious (but there was alot of dust to stick to and oil leaks) the r34 is spotless in the engin bay .

as i said earlyer im ner to turbos well anything fuel injected for that matter.

anyone who is using the stock gauge can stop replying right now .

umm, we're sorry? any reason for that?

what's that supposed to mean? that the stock gauge doesn't work for mods? that it takes these upgrades to get to 11-12psi?

it was a team effort :)

damnit, such a noobie question lol: how do i tell :$

ok gees i read your post so wrong the first time and realy ripped through you , my bad i have to read the full post first sorry . i deleted it once i realized

um from what i can tell is the series 2 has a shitty bumber that covers most the places you would like all your air to go , and it has a two tone dash and console . your dash lights are orange at night .

i think they have solid lifter in the motor so i thort maybe its a series 2 thing to have 11 psi ?

lol, yes, to make it clear it was my question that was the noobie one.

i'll have to have a look, it sounds like the differences are painfully subtle if you haven't seen them before.

buuuuuuutt. i'm reasonably sure that its a 1999 model, and i read elsewhere the series 2's were 2000 onwards. I say reasonably because the guy i bought this from had no idea: he had tyre pressures less than you'd put in a camry (the car has 235 front 265 backs and 18" rims), different front tyres, different spacer WIDTHS on the front (not even kidding), illegally huge spacers on the back, 3" catback exhaust (not 4 as he said), he didn't know the kw (and was surprised to hear it), nor the turbo type (as in different to r33), thought the amp under the passenger seat was an additional computer... (takes a breath) need i continue?

so yeah, how do i check what year it is? I assume it's somewhere on the engine, or in the engine code?

that would be because most of are here to learn from people such as your self that have been there and experienced that !!. and we apreciate all the help we can get as that is what forums are for .

i will make sure when i change the acutator hose i make sure its the hose made for that job tanks for that advice

i tell you what ill look under the bonnet now and get back to you but a dead give away is the dash light when you turn them on they will be orange if its series 2 and white if its series 1 (unless hes put different colour leds in it lol.

...yeah thebottom of mine said R34-37-2A (not much help i suppose). But the import sticker said 06/99, which i assume is year?

the tc and hicas lights are orange, the speedo and tacho are white

it will be a series 1 then

so, bringing the thread back into line:

what should the stock psi be for an r34 gtt s1 or s2?

As far as i have been told by my mechanic who has done a fair few neos the R34 gtt (and the stagea) was released with a few different set ups for the engine tune, maybe it was bought stock at 11psi, but it probably just due to your mods and maybe a tune.mine Was running 5-7psi when i picked it up but had a tune and wound it up to 11psi, no mods at all other than that, bog stock and it pulls 161rwkw.

Also the standard gauge is in hhmg not kpa or psi as someone suggested.

Almost. The standard gauge is mmhg or millimetres of mercury. 7 on the gauge (which is 700) equals 13.5 psi

Thanks for the correction mate i typo'd haha, maybe im dyslexic?

    • 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.
    • @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html
