View Full Version : T3 2.2 pistons/Rods in 2.4

Can someone please tell me the estimated compression ratio this would achieve. I have searched with no luck.

Fairly low after the first couple of revolutions. :) The pistons would contact the head.

Really. The pistons would stick up over the deck? I could have swore I saw someone do this before

There was a guy running 2.5 pistons in a 2.4 on Neons.org. He was getting 7:1 compression. The quench area is horrible with that setup, so you can't run near as much boost as you'd expect to be able to run.

To run the 2.5 piston/rod, you really need to deck the 2.4 block 0.06"(1.5mm). That pushes the CR up to ~8.5:1 and improves the quench. It's almost identical to the Mexican Stratus Turbo setup.
