Within the next 4 months im putting a b20b block together plus head and building it for turbo. As it sits now its b20v with a gsr head. it either has bent valves or blown rings. Regardless its all gettin redone. I kno b20s have thin walls but im using this block anyways. i plan on using golden eagle sleeves to toughen up the walls, low compression pistons with nitrous rings(lil nos never hurt anybody).

Goal 400-500hp 10-20psi(what ever gets the job done) spraying if neccessary.

What i need to kno is with the sleeves for the b20, no bore, can i buy 84mm pistons?

what rods work well.( size? brand?)

Gonna use acl bearings.

Crankshaft. throwout the b20? go with new one? Whats the best bang for buck crankshaft?

Anything else to throw in on this turbo build?

dont worry bout the head, its gonna be full blown done too.

Your current turbo build to help to would be nice

 

those sleeves are gonna be ur weak point for that much HP. they're the weakest sleeves of the B series family. goodluck

 

wow someone needs to sit down and read a little more.
