okay i bought a b20 vtec for 500 bucks from a buddy that was hurting for some money.. so it was a steal! but i have a question about the head... its b16 sir spec.. with the sir cams... how much more flow does this head setup have than a regular b16 a2 outa a 99-00 si? and what are the differences in the camshafts? thanks guys!

 

not much diff in flow or cams maybe...maaaybe 1-3 whp

 

but do you know what the flow ratings are on the head... im talking cfm..

 

tried to find the post its on another site. pr3 b16 gets the p72 gsr on the low end but not by a signifigant amount and the gsr catches up by 4-5k and then takes it from there until about 8k no signifagant difference though overal 1-3 whp is exchanged between the two heads (stock) whe either is flow better.

 

sweet! thanks that helped!
