rb20t vs rb25t power output

[Cubes]

btw.. I made 164rwkw which is 221hp on 1 bar of boost.

Its not just about peak power its the mid range that gets you there so the RB25DET will be quicker in accelerating to the peak power.

Considering though the RB20DET does do extremly extremly well in the power department. Especially considering the RB25DET has VCT, bigger turbo, higher static comp ratio etc..

Remember guys that it's about greater average power, not just greater outright power.

But it's amazing what the RB20 can do for a 2lt motor, there's no doughting that.

i just bought a rb20et silvia. has fuel pump. adjustable reg, exhaust, boost controller and some tuning by sub zero (dunno if i should be worried or not ) and made 220.5rwhp. with a upgraded clutch and 4.8 diff gears its heaps of fun!!!!

[Cool Hand Luke]

what is your number plate and what color is your car? I dragged a s13 silvia with a 6 and beat it tonight .

[BOOSTD]

works auto: you can drag me!

[RB20LagWagon]

Err he is doing 12.8s now boosted, and he knows what turbo he has.

[BOOSTD]

12.8 stock turbo 32, no chance. what turbo does works auto have??

[Cubes]

Depends if he is running slicks BOOSTD.

[BOOSTD]

hehe ,yeah traction helps :burnout:

[funkymonkey]

Just to throw some spice into the conversation, my CA18DET did 214rwhp fully tuned with an SAFC etc, and my RB20DE does 120rwhp with no tuning, no oilchange running 95RON fuel

its not about displacement sometimes...

[gjb977]

Go the RB25's !!!

[Cubes]

bah RB25.. Go the RB30DET..

[gjb977]

What's higher than a 30 ? Then go that !!!

Boostd's got a confirmed RB25DET stocker turbo and 12.9 seconds.

Whale's win !!! YAYYYYY!

[Cubes]

Didn't he say the turbo's front cover was different?

AND.. how long did it last running 1.1bar?

[Mase]

Snoop, are you doing the conversion yourself? If you are then i'd honestly put about $2500 aside for things such as timing belt, fuel pump, filter, oil, sparkies etc. Second of all, you will need to do something about the sump hitting on the sway bar and the clearance of the engine ie hitting the roof. Are you good with wiring? If not then put aside about 300 at least for getting someone to do the wiring and adjusting. If you already have a sr20det then stick with it. I promise you you'll be better off.

The front cover turned out to be stock aswell, I originally thought it was a VG30 item but that would mean it would be smaller than the RB25.

The turbo is still running fine after two and a half years( with a greddy cooler which I think increases its life)

I am having it rebuilt because a friend of mine was helping me pull it to bits and snapped my turbine off the shaft with a badly aimed hammer....=(

Rebuild specs b4 u ask are

compressor- T04B V trim

top 52mm

major 72mm

VG30 .7 A/R exhaust housing and turbine

[Cubes]

Ahh.. I thought you pulled it off because you said it was making noises...?!?!?

[Mase]

oh yeah, the $2500 was including the rb20 front cut.

[BOOSTD]

Joel: thats correct, the noise was found to be coming from the Exhaust to head gasket because of four broken studs.
