Well that all depends on what turbos you are using and what spec they are.

So provide more information and people will be able to give you a rough estimate possibly.

As it also depends what fuel you choose, how much more timing etc etc.

And soild mounting the motor... ouch!

I wouldnt recommend going much more with a stock bottom end, unless you have the money to spend for a full rebuild.

about 530 american rwhp, remmeber though.... everything is relative.

Generally most believe that around 300-330awkw is a safe limit on an internally standard RB26.

That said, I know of one car producing 450awkw on pump gas and nitrous with a stock bottom end that has done so for 2 years - Thats pure luck.

If you don't want to risk popping the engine, go conservative.

nice. yeah. dont test it.

[t51rb26]

just so you guys know im making 454 AMERICAN WHEEL HORESPOWER IF THAT MAKES A DIFRENCE DO KNOW WHAT HOREPOWER IT IS IN AUSTRALIAN?

WHY? IS THAT BAD?

[GeeTR]

WHY? IS THAT BAD?

SPECCY FUEL MAY HAVE BUMPED THE HP UP, MAKEING IT HARDER TO GUESS HOW ON THE LIMIT YOU ARE!!! SPECCY FUEL WILL ALSO LIMIT THE CHANCE OF DET!!!!!!!!!!

SOLID MOUNTINGS CAN DAMAGE HEARING CAUSING ONE TO SHOUT!!!

On a quieter note, TO4, didn’t (aren’t you still) making much more the 350kw on a stock bottom end as well?

[t51rb26]

any more comments?

[T04GTR]

umm no. it was 300. standard cams and t04z.

[T04GTR]

you can do it. but any hint of detonation and it will break a piston.
