Um....given that the GTS4 engine is an RB20 that hardly differs from the one in the GTSt (apart from having a different sump with the diff in it), why would you expect the engine accessories to be the same as GTR rather than GTSt? It makes sense for front suspension and other chassis parts to be the same between GTR and GTS4, but not engine parts.

the suspension is NOT gtr neither are the brakes they are gtst, however the power steering pump part numbers match to r32 gtr ones being that it is an rb20 yes however it is an awd rb20 and thus these things have been changed over, don't ask me why they just have, the diffs are also not gtr items they are 4.3's not 4.1's like the gtr. but the engine parts are due to the awd system installed.

my rb30 is fully built, spool rods, cp's 20thou over acl mains and bigs reground .25, cometic head gasket, rb25de head with 100lb springs tomei 256 cams greddy copy intake, hks 600cc's, still thinking about manifold have t4 to4e master power turbo Brazillian thing real deal, awd adaptor plate arp head and mains studs, what else obviously nistune ecu will be getting put in place still looking for good QLD turner for it around bris vegas and still thinking about the clutch as funds are becoming tight. also just installed NEW r32 gtr gearbox. and need new engine mounts thinking of nismo items aswell as nismo thermo, not sure what intercooler to run and need another radiator as i sold it to a mate.

it's not i can take a photo for you tomorrow to suffice the suspension is different,

i have the whole drivers side off right now for the engine conversion, i went to get gtr nismo suspension for it and found it's gtst

Piggaz i agree with you as i work with diesel engines and seen the stroke on them, it's just what i have ascertained through research and other peoples experience??? been told many MANY times to redline it at 7.5k i want to take it to 9k rpm or more personally, with standard crank.

ok a couple of things have changed as they do i am now going to use standard balancer and balance the F*ck outta everything, and am now using a low mount gt35r off an xr6, and have since aquired a nistune rb20 ecu but has to be remapped as the guy i bought it off only had it at 173rwkw with gtr injectors and such on rb20det due to mercury tuning it and it blew his engine :(

poor bugger.

one of my major concerns with ecu is the fact that mercury tuned it :-/ how damaged is it going to be and how leaned out is he mixture??????

Dude you can't just put an unknown ECU on your car and hope it will work, great way to pop a motor even if it is a good tune, it is tuned for another car, not yours!!

Get it tuned properly, why even bother getting an ECU if you aren't going to tune it?

You can't expect to buy an ecu and not tune it. You need to put it on a dyno anyway so while you are there you may as well pay for a tune. Not to do so would be very false economy.

oh yeah totally agree. but i am concerned with start up. primarily

trent with the r34 ecu with the IAT tables can you set up air intake ignition and fuel trim? I'd love that feature, not sure if I should just fork out for a vipec and put it in the standard case instead though.

An airflow meter adjust fuel requirements for differences in IAT.

Pretty sure the GTR ecu has IAT correction.

    • Pete knows these cars well, he does my car too, if he was concerned about the traction arm length for your use he would have said so. Do you have adjustable bushes in that arm, maybe he got enough adjustment there (or maybe the bump steer was not material for your use of the car)
    • Hmm. Yes. I should have been clearer. 1000s for Haltech, for extra headroom. 725s for Nistune. You might even be OK with 640s, but if the possible power ends up much more than 300 rwkW you will run out of headroom on the 640s. That would probably be OK and a signal to not push it to that sort of power with Nistune anyway. At that level you probably do want to be thinking about engine protection functions. Oh, and all of that presumes 98 only, not E85. Well....the 1000s would allow you to run E85 at ~300rwkW territory, again, maybe sort of running out of headroom. Hard to tell with E85 - depends on the tuner as to how rich they like to set it up.
    • Yes.  The only scenario I can imagine when the answer isn't yes, is if you drive like there is highway patrol behind you at all times.  If your car currently runs, enjoy it and keep saving. Better costs more, keep saving until you can budget the better ECU. It's worth it.  Nope. Plenty of us making >300kw on unopened motors. Mine is unopened and makes about 350kw if I turn everything up, its fine (lots of caveats here, how the car will be used/abused, how long you expect the engine to last between rebuilds, how has the engine been maintained prior to coming into your ownership, etc etc).   
    • Sorry just wanting to clarify, at this power goal, which should I be going? Also, More info regarding suspension, the rear upper camber arms were used to get the camber back to i believe around -0.5 ~ -1 degree (@ Road and Race in Rydalmere), I forgot the exact figure, but ALOT less camber than what it came originally which was like -2.5degrees. Are the traction arms still recommended? The bilsteins from SydneyKid, they've got 400lb/in fronts & 275/in in the rear, revalved to his specs. Intercooler, I'm just having a look at some on Rakuten.jp and some other japanese sites. Might get something from back there, GReddy, Blitz or HPI, all crossflow. Looking at roughly $450-$500 AUD + shipping... Theres not many choices except that chinese branded Justjap unless you go for blitz return flow. Yeah, only downside with Haltech is the price ahhaha, so expensive, and with all the sensors if I go that route... $$$$$ yeesh. Are headstuds/gaskets needed for <300akw?
