Hey guys,

Ive just bought a R34 GTT tiptronic coupe.

i know the basics about the car.

I currently have a S14 Silvia pushing 200rwkw aswell so i am no newbie when it comes to cars.

I am just wanting help in finding inforamtion about the R34 GTT's, could some 1 maybe point me in the right direction.

Such things as, What turbo it has on it? What are the AR ratios? What kinda timing can you run thru them on 10psi with the stock intercooler?

Are they an all alloy head and block?

Do they have a crank gurdle?

etcetc..

I know SR's quite well but am unfamilar with the neo RB25's and general R34 range. I like to know my cars inside and out so any help on othetr threads, FAQ's other sites etc are appreciated

Ive serached the forums a few bit, but only found limited info

THANKS GUYS

I too need some info on this car... I'm looking all over the place for confirmation of the turbo specs. I want to know what it is, T28, T3, hybrid? I'm being told differing things... I know it's got a T3 flange, but I'm told it's a T28... and I found something that said the A/R's were .60 compressor, .40 turbine, which would make it seem unlike any other turbo I've ever run across. Typically they're reverse of that, and the A/R's aren't an even .40 or .60... like .48/.63 or something like that. This is highly unusual to me. Seems based on the housing sizes, it would be a T3 compressor, and a T28 turbine... with the cartridge being a T3 or T28 BB, I'm not sure there either... ;)

I also want to know the trim, and the wheel sizes if anyone knows.

I've also read there's a series 1 and series 2, with the series 1 being the nylon comp wheel, and the series 2 being aluminum? Which really doesn't matter because the only thing I'm not liking about it is the Ceramic turbine wheel.

I've seen pictures on here if a series 2 R34 GTT turbo that was being sold... but it didn't have the A/R's stamped on it... so that didn't help.

I suppose a Part number might help, but then it might not.

I'm putting this on my USDM S14a 2.4L... I think it should make some pretty respectable numbers based on what I've read so far, and it ought to be big enough for the 2.4L but not laggy... my concern is the damn ceramic turbine wheel, and I'd LOVE to replace that wheel with a aluminum or steel wheel. That's another thing I don't know, is that even possible?

Someone help me out... and don't hate me because I'm from the US... I hate Americans too... believe me... I have to live among these morons... if anything, pity me... and help me out.

Yeah I've seen all that info too. It was easy to find. The turbo specs I'm after are HARD to find... I hope someone knows, because I'm putting this turbo on my car if it's worth using. So I want to know exactly what I got for my $240 (USD)... Which seems like a deal, but without the specs, it sounds like a turd that can't boost past 11 psi, with wheels that can't be upgraded to be able to handle more boost without breaking...

If that's the truth then... :( time to sell it to an unwitting american ricer with too much money and not enough brains. I'll tell them it's a Skyline R34 BALL BEARING Turbo and sell it for like $600... ;)

Someone give us some positive info. Or tell me it's a turd and I'll sell it right off.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that

      S1 rb25/s14 starting problem

      I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.

      S1 rb25/s14 starting problem

      By Duncan · Posted

      Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi
