R32 Ecu Change

[DVS JEZ]

Nistuned rb20 ecu, with a z32 afm in the cooler pipe if u wanted a big intake to the turbo

[Gts4RB30]

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.

O.....K. If the GTS4 front suspension is not basically the same as a GTR, then please report back to me when you have successfully put a GTSt swaybar (for example) onto your GTS4.

[Gts4RB30]

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

ok the 30 suffers from shit revs above 7.5k should have been more specific,

WTF is 'shit revs'?

85mm stroke is not long by any means!!! When will this 'RB 30's can't rev' rubbish die ?

[Gts4RB30]

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.

[Gts4RB30]

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.

I think he meant more that it won't make big power above 7.5k with stock cams etc.

[STATUS]

run gtr ecu with ait sensor and HPX maf in cold side, killer setup.

made well over 400rwkw with nistune and similar setup.

[Gts4RB30]

don't want they kinda power atm moment status happy with 250 to 300rwkw as i still have a 16month old in it.

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.

[GTSBoy]

There isno IAT measurement on any RB engine (except the 26). So there are no tables for IAT in the ECU.

[Gts4RB30]

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??????

[KiwiRS4T]

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.

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?

[DVS JEZ]

I recommend getting it retuned for ur car with ur mods.

Ur setup is ALOT different from an rb20 with gtr injectors and im guessing an rb25 turbo.

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

DVS NA MAN gt35r from xr6t

An airflow meter adjust fuel requirements for differences in IAT.

Pretty sure the GTR ecu has IAT correction.
