That's what I'll be doing, minus the turbo, since I don't have money for that.
There's no chip for the Super Eta,
Also, what "Racing seats" are you getting? Stock seats are heavy, but not getting true racing seats will not lighten your car much at all noticeable.
What are you replacing your fan with, since you're removing it?
with the i head and e block you get like 7.9 or 8.0:1 compression...worthless unless you build for 20+psi
Yes there is a chip for the super ETA its the same as the ETA silly
yes racing seats are about 70 lbs lighter such as recaro, corbeau, TenzoR, Bride
replacing his fan with an electric one
