compression ratio

how high of compression can i go with my stock ecu
im planing to build a b20 cr vtec
i want to do 85.5mm pistons or 86mm
i will probably use the b16a2 head or b18c1 head
i was thinking 11:5 to 12:5 ratio

Re: compression ratio (Ruben19)

u cant run a stock ecu with that set-up. it will run wat lean. look into hondata, chip your ecu, chrome, uberdata. you will need bigger injectors too

Also if you plan on doing 86, you're gonna be re-shaping your combustion chambers.

And what sense does this make?
