Piss easy just turn the CAS anti clock wise as far as it will go and run normal unleaded. And listen to the orchestra of sounds your engine makes.

Im assuming you want this for a 180?

Think maybe we loosing sight of what the Q is RB20det cut for $1500 Vs RB25det cut $3000

basically RB20det and $1500 mod money (maybe a high flowed T3 in that)

Vs

Stock RB25det

Either way make sure you get the coresponding engine crossmember and brakes.......

REV210 i woudnt mind having a drag against you at motorplex and kicking your ass...

STOCK TURBO VS STOCK TURBO

:shake: :shake: :shake:

13.3 @ 108MPH

[rev210]

works auto,

you have already kicked my ass, 13.3 vs 13.4 says so. I don't think it would be fair next time cause I've got the s-afc in since last time and you still have a std ecu? or is it re-mapped?

Anyway if you can get it into 12's it should be a good race cause thats where I will be next time down there.

Mr Mayhem,

Sorry mate, I did miss quote there. I agree about the 3L totally.

Ballistic,

Thanks for pointing that out it was very funny. Do you also find faults in movies? you should start a thread on it...No! a whole forum! Wait a minute....your an english teacher aren't you! You'll never make me read the Mayor of Casterbridge, I'll fight you till the last!

barry is telling u fibs mate!

[MrMayhem]

also in my reference to lag wag's R31 RB20det 1390kg truck fmic 3" and a high flowed VG30 T3........ he ran 12.7 tonight on street rubber...... bang for buck chuck

[S13 Silvia]

The only reason snoop started this thread is coz my rb20det silvia whoops his sr20det 180 ass

Now his working out how to beat me, either with an rb20 or 25, hehehe

[EnricoPalazzo]

Ahh so the truth is reveled.

[funkymonkey]

get an RB31det... well there's an RB31DETT so I'm guessin you caould get an RB31DET.. and yes its thirty one not thirty... my cuz jus imported one by accident to Sri Lanka (the RB31DETT came in a GTS4 of all things)... he said he'll send me pics when the car arrives.

[Chino]

tha man... works auto ANGRY ANGRY but yer man..... dont the r32's come with weaker running gear then the later r33

[randymoss]

guys I've got an r-32 gts-t. Was wondering does it take much to get 200KW at the flywheel?

[Skyrine-Dave]

hey guys

what kinda estimated power would my car be putting out?

specs are as follows:

HR31 GT Passage (1440kg)

R32 Silver Top RB20det

3" from turbo back exhuast

high flowed R32 RB20det turbo

EMS Dual Sport I 604

Boost cut of 105kpa which about = 14.7psi

stock R32 cooler.. temps sit around 39-41deg

any ideas ??

Thanks

Dave

[R31Nismoid]

Mate...

I reckon you'd be good for min. 150 at a bare min upto about 180 Rwkw.

I'd predict about 170.

[JIM-85V]

just a question what price do those 2.4 stroker kits for the RB20 go for?

cheers

[Cool Hand Luke]

I think what sydneykid was originally saying, is that if you had an RB20 and an RB25 both with RB25 turbo's they would both have similar max power output. The 20's turbo really hurts its performance, but one advantage with a 25 is that you can run bigger turbo which also equals more power.

[rbs13]

i think you can use rb26 crank and rods and get some 86/87 or so MM pistons to make your rb20det into a 2.4L.

[sumfatchin]

a dude i know has an rb20, with full 3 inch exhaust, big front mount and achieved a best of 221.4 rwhp running 16psi (yes 16) through his stock turbo. My rb25 makes 221.1 rwhp with just an exhaust, running at 13psi.

[Cubes]

sumfatchin... The RB20DET uses a small arse turbo.

Slap a R33 Turbo on the RB20DET and at the same boost pressure you are looking at around 15rwkw more.

So 15rwkw more on 221.4hp is around 241hp at the rears.

The RB25DET also has the advantage of running a higher static compression ratio compared to the RB20DET which equals a little bit more power BUT you are unable to run as much boost so really it evens its self out with a RB20DET running 2 psi more on the same turbo compared to a RB25DET running 2 psi less on the same turbo.
