2G Wiseco evo pistons turbo tuff rods

[GSXvsTSI]

I'm building my engine and bought some Manley turbo tuff long rods with 22mm wrist pins.

These will work perfectly with evo pistons but i'm trying to figure out compression ratios(because evo pistons aren't as tall as 2g pistons if im correct).
The pistons are going to be wiseco and here are my options.
-1400HD .020" 9:1 150mm rod
-1400HD .020" 8:1 156mm long rod
-1400HD .020" 8.8:1 153mm stroker piston
-1400HD .020" 9:1 150mm stroker piston

I want the compression ratio to be between 9.5:1 and 10.5:1

If none of these will work i can just get wiseco's normal 2g .020" 156mm 9.5:1 pistons

The difference between the evo and the DSM engine pertaining to compression is the Cylinder head combustion chamber size. just pick the compression ration you want based on the head you have. They sell HD pistons for 2G DSM's it'll be a closer match.

Evo - 43cc nominal
2G Eclipse - 47cc
1G Eclipse - 49cc

So I should get the 1400HD .020 2g 9.74:1 Or the 8.55:1? Where does that put the c/r with those long rods(what I have).

It already has a deck clearance of -.3 and with smash into the head wont it?

Think I found the perfect match

This thing is a beast!
