the shop that is goning to do my work has one of the best Crome tunners in the country. He is the one that told me to get type r pistons to use with b16 head and it will give me 11.0/1 compression. Thanks for advice on shotpenning will do. I am planning on 50 shot of N.O.S also so want be only motor. Thinking the nitrous and some drag radials may put me in high 12sec quarters maybe. Thanks for all help and anymore that may be given.
