I was looking around at turbo specs on evos and seen that gh he evo 7 uses a 85mm piston. Would these fit on f22 rods and would the compression be simular to the evo. Also do you think the exhaust manifold would work? Thanks for the input. I think it would be a interesting set up

 

ppl use the evo stroker pistons in f22 blocks a lot. I'm glad to see someone has done their homework and is willing to think outside of the box. Just make sure to do good research on that set up. cb7tuner.com has good bit of info on using evo pistons in f22a engines

 

For the record though the evo7 and your f22 have the same compression ratio(8.8:1).

 

Thought the evo ran 9.4/1 cr. Just thought it may raise cr a little. AnY way thought it would be a sick combo. Kinda like a 2.2 evo motor. Would there be a benifit to running those pistons or no?

 

Everything I see when I google "evo 7 compression ratio" says 8.8:1.

 

So what you saying is same cr so probably no better than the pistons I have. If thats the case what would be a good choice down the road? I want something not everyone has. Would like to make 250 whp maybe 300 topps above that would be crazy, couldnt get it to the ground. Anyway im open for outside the box ideas. The build would be on down the road as my motor runs good but may pick up another block to play .
Im still putting the car back together as we ripped most the car apart to fix wiring and such thanks in advance for any.
input.

 

The f22 stock can easily make 250-300 with boost. As for a build I would go with something aftermarket.

 

ppl use the evo pistons b/c they are stronger than f22 stock pistons. Ringlands don’t fail and cause catastrophic damage. From what I have read stock evo pistons will handle around 400ish hp. Stock f22 are gettin push to limits at 300hp...so out the window with reliability. So even know your keeping around if not the same compression ratio you getting a much stronger piston.

 

Thanks for clearing that up. So if one wanted to go over say 300 hp they could use these pistons as a minor upgrade to the f22.

 

well your gonna need some head work to pass the 300hp goal and at the point if your swapping out pistons you might as well get rid of the f22 rods and get something stronger.

just remember you can have 2 of the 3...

cheap
fast
reliability

chose wisely
