I have a stock Ls block and head, Si clutch, and JDM SiR pistons (10.4:1).

I'm getting a Cable trans form a junk yard along with the harness and axles.

Does any one know if I could use this clutch? Its a ACT HD with 3000 miles on it and I would hate to throw it away.

Also What gain do you think I should get from the pistons over the 9:1's.

Its all going into my hatch if your wondering.

Thanks for the help.
 
Also I would like to know if the Ls head would effect the Comp ratio of the pistons.

My future plans include 403 cams and valve train upgrades to handle the revs, and maybe some Gas ( 30hp-50hp shot )

If anyone has a Ls in the 88+ hatch I would like to talk to them and see what they run.
 
i have a 90 si hatch with a 93b18a motor, i ran a 15.2 @ 94 mph on street tires
As for the clutch only way to tell if it wrks is try bolting it on. i couldnt tell ya
