I got a guy who is selling me a kit for the H22a1 ( closed deck ) but since I'm at it. Boring it out is a must.

Plus how safe is running 11:5.1 with shaved head. 30- Can I still used pump gas,or will it detonate. I have a V-AFC and a near by Dyno to help me tune the car.
-THANKS

 

you cant bore out stock prelude sleeves. you must run aftermarket ones, as i assume you know. darton are great, i have them and ive only heard good things about golden eagle. be careful with a shaved head, a buddy of mine had a shaved b16a head and ended up blowing it after shooting NOS, he didnt have his timing set correctly, i know you are running NA, but take the proper timing precautions. if you are properly tuned, you should be fine running premium gas.

 

I know alot about tunning thanks to the DYNO's, I only made 3 runs and I accomplish 198 @ the wheels. I could of accomplish well over 200 its that I went to one of those outside Dynos

But any ways, my block blew up because a rod bearing went bad, Plus the block I had was some Bullsh*t. So I'm going back with my 1rst orignal block, and putting sleeves into it.
