Maximum Power Achievable With Hks 25/30's On Rb26?

[bb_gtr]

Hi Guys,

As topic states..

-What is the maximum power achievable or have people made using HKS 2530 or "Garrett -5" turbos on an RB26 R32/R33/R34 GTR? (On either a stock internal or forged engine)

-And what is the maximum boost you can run on them before they run out of their "efficiency zone"??

Any input would be great... Thanks in advance

350rwkw on 17psi.....

So many variables.

Dirtgarage had something like 420rwkw?

Also, figures at 4 wheels is possible?

Im using them as well, making 375-380kw at 4 wheels with 18-19psi. With stock bottom end and Tomei Type B Cams in an R34. Other mods were just usual ECU, AFMs, exhaust, air filters, fuelling.

Over 400rwkw

Over 20psi

A simple search and/or read of the threads returned would soon tell you what people have made on them at their peak.
