Whats the highest compression I could run on a DD b20 vtec with regular fuel?

 

i'd worry more about what comp. you could DD on stock B20 sleeves.....

 

I could dd on stock sleeves. But if im going to build it internally. Why not get it sleeved? I'm a detail *****.

 

I'm at about 12.5:1 on stock sleeves and pump 91.

 

so if i ran 11:1 comp I could use pump gas? or could i go a bit higher?

 

I'm at 12.5:1 or slightly higher and I have no problems. it's all in the tune man. Take it to someone who knows what they are doing and you'll be fine. Check out the All Motor forum, there are plenty of guys in there running high compression motors on pump gas.

 

thanks man. I live in oklahoma so the only tuning shop near me is for mustangs and ****. I will probably have to make a drive.
