Anyone have experience with these in a b20? I couldn't find anything, seems everyone runs the ITR ones. Claim 13.5 compression with a b16 head, maybe enough to squeak by on with pro3's and pump gas.

 

You'd need to retard timing so much, the added cam/compression wouldn't be a benefit.

I'd also be suspicious of P2V clearance on cast CTR pistons and Pro 3's.

 

Yeah I should've searched more before posting, was trying to look for b20 setups and there were none, a few ls-v though. None seem to have lasted more than a year. But it looks like they're ping magnets. Will go with itr and pro2's thank you.

 

we have this piston in an b20 engine with ported head and pro 2 cams. made a gooood power.

 

What fuel? Pretty sure Europe has better octane ratings than the US, we're limited to 91/93 RON most places.

 

We have roz 102 octane. Expensive premium fuel.

 

Yeah. For OP or someone like me to run that setup, we'd need to use either E85, race fuel, or meth injection.

A good piston + cam combo on a B20V goes a long way. 12.5:1 and Pro 2's are fullproof.

 

Do you have any dyno charts by chance? Or remember what it made? If it makes enough more than pro2's and itr pistons I'm willing to stick with e85, thank you.

 

With that cr with pro 3 cam on e85?i see no problem at all!

 

How much power ? i have the same pistons but I just barely ordered the rods . Can I use this with my b16head it has super tech valve train not ported and when I bought the head it came with skunk2 pro series stage 1 cams with golden eagle cam gears ... can it work??? Or can this work with a stock head ?

 

hello I'm new here and at the moment I have a project in my hands that is not at all well, what do you mean that it is necessary to delay time, can you clarify me better, I have b20 with b16a2 head and 85mm ctr pistons of cupula o car does not start
