With a full port and polish along with CNC work and larger valves you can get a set of E7's to flow much better than stock GT-40s. About 220cfm to 185cfm.
I also read gtsr515 as saying GT-40 heads would give you 8 tenths. I agree you could pick up 8 tenths with a GT-40 head/intake package with some 1.7's on the stock cam and a couple other little mods. Then again, for $200 less, you could do close to that with ported E7s. I would spend my money on new heads rather than porting too, though. |
