GTR parts

[R33rr]

what gtr parts can be installed on rb25det motor
A list or anybody tried to their rb25
And gain from gtr parts

[RSi]

Cams, injectors (with resistor pack), cam covers

[cozmosland]

honestly not a whole hell of alot.

[RSi]

+1 for NOTHING WORTHWHILE!

Do you have a parts car?

[Skym]

RB26 bottomend inside RB25DET block = lower compression or RB26 bottomend including block. By the time you turn a RB25DET into RB26, should have bought a RB26.

RB26 intake plenum + throttles + fuel rail, etc with adaptor plate for different bolt pattern on RB25DET head.

RB26 twin turbo exhaust manifolds with adaptor plates for different bolt pattern or custom flanges on RB25DET head.

RB26 head (solid lifter, more aggressive cams, etc) on RB25DET bottomend.

RB26 topfeed fuelrail on RB25DET head (I think it needs spacer modifications for mounts on fuelrail due to being topfeed fuelrail instead of side feed fuelrail on RB25DET).

RB25DET camcovers have the breathers in a better location. They used RB25DET camcovers on R33 JGTCC racecars.

[RSi]

So yeah... +1 for nothing worthwhile

[cozmosland]

but good having more information

[RSi]

Yeah well... I could fit pretty much any intake and exhaust on with adapter plates...

parts

I was just wondering what parts are easily better than oem rb25det parts .
And i was wondering if replacing them with gtr parts . Cause it seems like a lot of our members are selling them .
I know there is after market parts . I have no clue what brand or make .
For instance ok, my goal this winter i just want to replace .
and clean up the engine bay. (IE.) Intake maniflod and plenum , not sure if top feed rail and fuel injectors , or leave stock as i dont know What cc is on stock injector. , water pump , oil pump,gas pump , regulator , and possibly an upgraded turbo like from r34 . i was told that would be a decent upgrade alone .(17psi). EBC- HKS , Test pipe.
I just got OBX turbo elbow,(still awaiting arrival) from downpipe to muffler are 3" hks . so i think exhaust side should be ok. I also have FMIC which is also HKS.
My goal is around 350 whp.
My ecu will be chipped to max my rb25 by ztune.
So any input would help me out on winter project
.

[RSi]

Oh you are going to ztune to chip the ecu now?
Just so you know - they can't do it.

[R33rr]

chip ecu

huh , ?

[RSi]

You are Dale, right?

[R33rr]

chipping

yes , rich
I havent decided yet cause they said they could but i ask them if they have extra chip so i can keep the one i got , gailen said he has to talk to the person thats doin it . I dont know who the guy is. As i met most of the guys there . So still finding out if they can tune my car with another chip. And also they want me to install electronic boost controller and a test pipe .
I havent made a commitment to have them do it for me yet so , im still finding out if they can chip my ecu or not.

[RSi]

I think you will find they can't do it....

[cozmosland]

he means an r33 ecu is not easy to chip like an r32 is
