5sgte compression ratio Options

[b1gr3d]

I cannot seem to find anything on the cr 5sgte conversiion if the 5s rods and pistons and a gen 2 3sgte head?? All I can find is that I need to get lower comp pistons

what HG are u using? HKS offers a 8.5 and a 8.8

head doesn't depict comp ratio, its all down to the pistons really unless you use a different HG (8.5 or 8.8) 0.4mm thickness difference
3s head is jsut a wide angle version of the 5s head

so with what you are saying you'll stil have 10.5:1 unless u swap HG

if you want lower comp, my suggestion would be 5s rods, custom 5s 8.5:1 pistons, 8.5 comp HG that will put u at 8.5:1, great way to go to reduce knock at 20psi+

Je offers .040 overbore 8.5:1 pistons which will run you about 900$
if you stick with your 5s crank pauter wil make you up hybrid 3s/5s rods. I would advise against it though as you have a 95', the crank is NOT forged
