Re: Turbo 5sfe HELP!
Lost pups get in big strife!
Depending what year model 5S, the block may be suitable for boost but I doubt the head would be worth the candle.
FE won't flow nearly as well as a GE head. Different valve inclination angle, smaller ports etc.
Check if the block is in good enough condition to be bored. Rust in coolant galleries, cracked, warped etc.
Quality pistons, rings and rods. ARP bolts throughout.
Possibly a 3S cylinder head and some significant work on the crank and it's lubrication.
