Turbo 273 ?s

honestly i have no idea what the 273 has for compression i have no idea if its rebuilt but it runs decent and has been repainted so i just asumed its been freshend up.


For all i know it could be a custom turbo? It spooled pretty easily on the magnum. Only thing iam worried about is if my exhaust manis will be to restrictive. The turbo mounts on the pass side about at the valve cover the driver side feeds into the pass side where the pass side would normally exit the turbo is fed at the middle of the exhaust mani and the wastegate is right under the turbo faceing the radiator.

I will put some pics up today

I love the lumpy sound of a big cam i was thinking something around 500-510 lift but would it hinder performance? What do you guys suggest. Iam not tottaly new to the turbo world i have a 450whp spirit r/t just new to turbo carbed setups
