The rb25 turbo is a good budget upgrade..
A highflowed one would do quite well i imagine..

Dynos only Steve - its one of those mods that is useful for angry dyno spitting cars. Todd owes me many hp does he not? :)

:) Sorry Steve i shouldnt really question the experts, but im kinda intrigued as to how far she could go.

Though after the chat on Thursday we might not bother with such a basic turbo.....

Ive seen 270rwhp on a hyperdrive dyno from an r34 turbo on rb20! Full boost abit after 3000rpm, was a pretty good combo! Much better than a hi-flow that'll make 300rwhp but give you heaps of lag, on an rb20 thats shocking! I know from expierance hehe
