rb20 with rb25 or 26 crank and rods with a t78 can deliver 600+ easy and the

rb is an iron block oversquare engine so it can rev higher too.

the sr is a squre engine and alloy construction and even tough has its

advantages over the rb, it cant be built to the same peeks.

go luck on your rb25 build.
ahem do not forget the mighty rhombus. 675rwhp and hodls the US SR20 hp record. Now europe has one SR in the 8s making over 800whp i belive. And the madtech car makes around 700 flyweel
