Is it safe to put any higher compression pistons in a B20 block without sleeving it? If so what's the highest?

 

ur gona get mixed reviews on this one. I have a b20 myself and have done alot of reading. Seen guys pushing 240 whp with stock sleeve b20's. all motor applications. Biggest thing is to get it tuned so there is no detenation, that is what actually cracks the sleeves.

 

I have a DA and I wanna do a B20/vtec swap and im not sure what I should do to the block. All I want is a little budget build for the summer.

 

If you are gona do internal work, i would upgrade the rod bolts with arp ones. you can actually use gsr rod bolts but you have to get the rod machined to accept them. THe gsr ones are little bit bigger. Pistons i wouldn't go no further than 11.5 to 1 comp on something you gona drive everyday.

 

ask MP5, he has a b20 boosted on like 14+psi and he beats that thing up. he hasnt cracked a sleeve but its also in the tuning.. that right there made me jump on the b20 bandwagon.

 

Thanks man. Have done anything to your B20?

 

not yet. i think im gonna just boost it...

 

17 PSI.

I am doing B20 turbo right now. My car is sitting as a shell. I am waiting on my clutch and axles and hopefully putting it in.

Here's my idol: Click me.

Some people on this forum may know that car that Matt tuned.
