What pistons will yeild a nice 12.1 cpr on a B20vtec. Any suggestions or recommendations from past or current experiences.

 

I have a set of new 85mm B20B pistons with rings and pins for $150. With some surfacing you won't get 12:1 but at least 11:1.

 

Try IB. Jeff has what you are looking for:

Other manufacturers offer pistons that will do the same job as well.

 

HAHAHA! I know of some very cheap high compression pistons for a b20!!!! HAHAHA!

 

JE has off the shelf 12.5:1....I bought some from Summit about 2 years ago for $500.

its 12.5:1 with the B16 head...with a normal B20/B18B head, it will be around 12:1.

No because ITR pistons are only stock at 81mm so there over sized would only be .25 over that... B20 has a stock bore at 84mm with a 87mm crank... Thats how you get the 2.0lt
