NA 20B dyno sheets?
Havent found a lot of info on this. Hopefully Gordon and others will chime in and maybe give me some good links for NA 20bs(not interested in P-Ported motors). Even better if there is any info out there concerning NA 20bs with nitrous 
Just curious.

David... I will post some dyno sheets at the end of the month. I have a few, but the dyno was crapped out and they're not accurate, though I think the power curve for torque and hp are right in shape. I'm hoping the dyno gets fixed in the next two weeks and I'll rerun mine. I think I've seen one or two other guys sheets and will try to find them.
I think they vary in peak power from about 275-480 whp. The high end are p-ported motors with lightened and clearanced rotors and eshafts with ITB's and high compression (10+:1) rotors.
I've already discovered how sensitive these things are to intake and exhaust sizing and lengths. Fortunately, its going to be pretty easy and painless to try different intakes and exhausts. Everything's bolt-on and you just retune it.

Im assuming I will be on my own when it comes to NA headers?
Thanks for any info as I have searched and there isnt much out there.
