[dreadr31]

Yer i am happy with a stock 25 but i always want more

[zebra]

Simon-R32 is revving his stock 25 to 8k and making 360rwks with a t67-25G

but its not a drift car

yer my 32 with 25 would happily rev at 7800 at 270kw with my 4kg aloy fly wheel with the same turbo set up as simon-r32

the t67 on a 20 might not be to good haha but i have been thinking about it

Ifraz (sp) makes 640hp at the wheels with his RB20. Pretty sure it has standard rods and yes RB20's will do 9k every day. Even with standard rods mine didn't fail until the oil pump finally let go. It saw 9k rpm most of the day for 18 months. Put in some rod bolts and it will survive.

If you want to rev to 10k + I would get a forged crank for a 26 and do up the Neo engine with a 2.8 stroker. 290 - 310 degree x 10.5mm lift cams and all the supertech gear in the head.

It will swallow babies but it will sound like an FA-18 on take off.

iv pulled down a few 20s and 25s its seems to be no proplem to install a 20 crank and rods in a 25 block

so a shorter stroke and a comp ratio of around 7:1, but i could get the block decked to bring pistons back to level

[chocco]

Would a 42r be any better?

[dreadr31]

yer not to keen on a stroker kit

aslong i got power to 9000rpm ill be happy

[The Dan]

RB20 + GT35R 0.82 = power to 9k

[chocco]

RB20 + GT35R 0.82 = power to 9k

Over 9000???

[The Dan]

My only advice would be to wear protection.

If you are going to hang your dick out the window, which it sounds like that is all you want to do, don't be upset when the guy with the better setup passes you sideways

Over 9000???

If you talk nicely to it

The most insane RB track car I've ever heard, as well as a large amount of guys from the drifting in melbourne was powered by a stock RB25.

Of course if it had 290 degree cams and a smaller stroke crank with custom rods and pistons it would've been better

Panik hands down for me, best sounding RB I have ever heard

[R31Nismoid]

Sounds similar to the car Steve speaking about. Not sure which i prefer, hard to get the exact from video but having seen the other car in person it was certainly the winner. Best I've heard in 10 years!

Stock 25 head, 3ltr, 6boost manifold with a gtx35. Not sure of the gate/exhaust combo etc.

Sound is as much to do with the manifold, exhaust, gate size, angle/length of screamer as it is RPM anyway.

You could rev to 9000rpm and it could sound shithouse.
