Has anyone heard of the B20's failing with turbo added to the mix

any engine will fail with turbo added if it is not tuned correctly. i had a turbo B20 and it worked perfectly. just make sure you get a GOOD TUNE!

^^from what hes told me, chris's (onefst91hatch) was fast as fuck.... till the return line (i believe) blew off. im thinking about going this route myself. but im wondering if an ls block would work with a b20 head?...

OBD2 ls 's came with the P75 B20 head. but if your gonna use a B20 at least put some LS cams in it. the B20 cams are a lil milder than the Ls ones. and im guessing i made about 275-280 to the wheels with my setup. but it was the torque that was outrageous. i miss it. and it was the vaccum line for the waste gate that blew off lol. 18 PSI no bueno with 450cc injectors and 7 psi tune!! lol. bye bye head gasket! and yes it was all stock B20 with mild port and polish and 5 angle valve job, all new bearings, new factory pistons, and all new gaskets. other than that... ALL STOCK. i loved it. i couldnt blow the damn thing up! i tried!
