the na block dosen't have oil squirters, not a problem unless it's going to be a road track car. theres plugs in the oil passages you can use for the turbo. of course you'll need to change the pistons and rods and the head has a port for egr valve that needs pluged. the valves aren't the same as the turbo head. i'm using a pt motor for my twin turbo project. as long as you build it for boost it will be ok.
heres a pic of the project, twin s3 turbos, full built head w/s3 bc cams and forged bottom. and yes, it's a motorcycle.
