So finally came across this


Looks a lot like many other DI systems that inject from the side. So for those who are looking at low CR pistons wouldn't Wiseco know how to make them then? I'm assuming they'd still have to order a 2GR piston, but they've already done low CR pistons for mazda's DI engines.

CP has made pistons for the ISF, so you could probably give them a call also.

 

ah didn't know that. Hmm, I bet they're compatible since they're same bore size and utilize the same fuel delivery setup. I wonder if anyone has done the calculation with how much they'd have to lower the CR if they swapped in a 1GR crank.

 

That piston looks happy! CP has a piston for the IS-F and I think its the same for the IS350 2GR

 

Didn't we debunk the "350 and F use the same pistons" idea in the last thread?

(though I agree they ought to have some idea how to make a 350 one based on what they learned making the F one if they have made a set)

where is the IS-F piston listed BTW? their catalog doesn't have it-
