hey peeps....id like to ask u guys for opinions on my 4g64/63 build....ive noticed u guys here in the states have got a bit of experience with this combo....so id like to know what sort of power is a safe figure in hp .....also for dyno figure differences, what is a stock evo 8 putting out at the wheels? im askin this cos power figures in australia seem to be a bit different to u guys here

thanx in advance!!!

engine specs are....

64 block
64 crank
acl bearings
scat forged rods
wiseco forged pistons
arp main studs
arp head studs
cometic 87mm h/gasket
standard 63 head port
bc valve springs
bc 272 cams
63 head

 

if its built and tuned properley i cant see why that combo cant support 600fwhp safley. Who's doing the motor?

 

springy performance in springvale are building it.....so far so good with the build.....bottomend is all together and all measurements are spot on and consistant with bearings and rings etc...
