Stock flow numbers? Does anyone know what they are?

 

dont know the numbers but the 22 is a vtec head... the 23 isnt... didnt know if u knew this or not...

 

I guess the real issues is this. Project with H22 head and boost now. Seriously thinking of going with the H23 non vtec head but I'd like to know what kind of gain we'd get. You know , before and after deal.

 

am still runing the h23 head but the h22 head going to make more power but i have seen 650hp out of a h23 head

if its just race car h22 head

street h23 head and send it to port flow

vtec heads allway flow more cfm stock then a non vtec

 

R & D Dyno would do the porting, you wouldn't happen to have the numbers?

 

nope i dont know the stock flow cfm

 

anyone ever bored a H23 bottom end to 2.5L?

 

don't think it was bored out too much, but that block spacer was used to make a 2.7L I believe at R & D Dyno.
