although i built by b20 with a eagle/wiseco combo, you should take this to the Forced Induction froum...

or better yet...SEARCH!!!!!

 

agreed, you should search and also talk to your engine builder/tuner. And good luck boosting a b20 with stock sleeves, it would be wise to sleeve it or just get an Ls block.

 

I already have searched, been told to get my compression down to about 8:1, thats all theyve told me, didnt tell me which parts to use or anything, Ive searched and all i could find was how low to get ur compression, now what parts to use or what brands or anything
I already have the block sleeved with a 3 angle valve job

</TD></TR></TABLE>the compression is dumb low even for a F/I set-up, i would say you should go with a higher compression then that. And a 3-angle valve job? i hope you talking about your head.

 

yeah, yeah, sorry for the confusion there
I have a b18c5 head on my b20z

Should i go with 9:1 compression?
