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.

    • You’ll be very upset when you bust that too not to mention the gearing totally sucks. Don’t do it.
    • Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?
    • So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch
    • It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.
    • As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.
