Quick question

[Rich777]

How much bhp would a stock b18c block that had been bored to 81.5mm handle ? Also is it a good idea to uprate the valve train ?

Anyone ?

Anyone ?

anything in excess of 300++whp is risking it quite badly. although there are some people who had done this before, more attention should be made in maintainance & while driving it (i.e. always check AFRs, fuel press, maybe oil press etc.).

I was hoping to aim for about 350whp really but never mind. What compression ratio should i aim for to ? Ime thinking 9:1-9.5:1 ? ?

with race gas and a good tune you could probably make 500whp, how long will it last? who knows... anybody shooting for 350whp reliably should install forged pistons and head studs and minimum.

edit: 9 to 9.5 will be very reliable on a good tune, plus what he ^^ said

Ive got arp head & main studs already so i'll be ok there then. Ime looking in to pistons at the moment, ime probably going to get a set of weisco's. Ime also going to be running the car on 99ron fuel.
