for 10 psi of boost would it be necessary to go out and sleeve or just put a block guard on and a girdle? i hear stock sleeves handle 10 psi well until you go either 14psi+ or double stock output.....going around 300-350hp with mods and boost would the guard and girdle handle it well? got some eagle rods and wiseco pistons pistons are +4.00cc stock rod length stock crank refinished. not sure of turbo was given to me for 50$ no oil leaks...i think its out of a 2 liter ford...will need to fabricate a exhaust manifold to use the turbo...its a start lol thanks again guys
