Thanks

apparently an NA makes 190 hp at flywheel and GTST 230 hp at flywheel obviously turbo is expected to make more but a stock turbo against a modified NA can have quite even results. havent raced a gtst but im sure id keep up with one!

My r32 doesnt go to bad, its not level but the turbo doesnt get a full length on me, but the turbo i raced has a few probs to iron out, my cars got a 2.5ltr so yeah its a evenish comparision for the r33, mine a bit lighter though, got nfi what the power is though.

If it is the RB20E engine, then the output is 130PS from the 2 litre, single cam'd engine....

The RB25DE puts out more and benefits from the extra 500cc and twin cam setup...

Here's what I got when I dyno'd my car. From the responses I got, it seems to be on target for a stock GTS.

What models came out in the r33 that where non-turbo??

[NS2500]

GTS - 2.0L N/A + RWD

GTS25 - 2.5L N/A + RWD

GTS4 - 2.5L N/A + AWD

basicallly your looking at 142kw at the engine for any RB25DE, 2.5L engine thats not neo(r34)

the R34 RB25DE made about 147kw at the engine, some ecu changes and a dual inlet throttle settle nets the extra power.

[Demon Dave]

The Neo engines also get variable Valve Timing:)

[Nismodified]

my bad =)

But....some rb25de's had some sort of variable cam timing?

not mine however

[Demon Dave]

AFAIK, when Nissan released the R34 range they decided it was time to give the old RB series a bit of revamp - hence the introduction of the Neo Strait 6 engine. In addition to various other improvements the Neo engines got VVT, however the GTR's RB26DETT did not. (this may be the reason that Nissan can get away with quoting the official power output of the R34's RB25DET as 280PS & the the R34 GTR's RB26DETT at 280PS also!

I have seen 1, R33 series Skyline (late model) that had a Neo strait 6 engine in it - whether Nissan officially produced the R33 with the newer Neo's in it I can say - it could have been a conversion or something as simple as bolting on the "Neo" plastic engine cover...

So... if u had a gts-t pull up to a,say, gts25..would the turbo totally SLAY the 25???

[Demon Dave]

most probably...Yes. Both standard, of course.

R33 GTS25 = 2.5 litre N/A

R33 GTSt = 2.5 litre Turbo

[Nismodified]

slay.... well i dont think that would be case

it all comes down to the launch of the turbo, they are pretty tricky to get spot on.

if u get a nice launch, dont expect him to blow u away too easily, cos the turbo will have to earn their keep !!

[YnVmE4]

hrmm... Wat does the turbo make at the wheels compared to a gts25?

[DLuded]

a turbo is about 187KW at the fly which is about 140rwkw

i raced a gtst from a rolling start and it was dead even, although his car does need a tune and is dead stock.

[Nismodified]

for manual rb25de car, perfect launch. expect a best of low 7's and mid 15's

i also feel there is alot of potential for modification

[nismoman18]

HPI has road tested an NA GTS25 against an NA Supra, their figures show 0-100 in 7.3 and 1/4 mile in 15.5 which is accurate in my case cos ive done my 0-100 in just under that time and the quarter sounds right. the car made 105 kw at the wheels, this is stocko with a muffler i think, pretty good i guess, id like 150 at the wheels on mine

I timed a constant 6.4sec from 0-100 and best time was 5.83sec. Mine is a 97 GTS with HKS Drager and Trust Air Filter. This is measure from Apexi Rev&Speed Meter, don't know if it's accurate though.
