well cant argue with you there..but question is..why do people say gsr cams are better for turbo???....i mean the thing with a gsr and b16 head is..when u go to turbo..once u put down the numbers..its not gonna matter which head you have..big numbers is big numbers...thats how i feel..i feel that if my car is gonna be turbo...as long as i have a b16 or b18 vtec head...that when i go to turbo,its not gonna matter which one i had in the end,because the turbo and the head are gonna end up working together anyway..i mean i could understand if i was going NA..cus the head really matters then...but going with forced induction,as long as the head flows good,then my setup should run smooth (with fuel,ignition,and tuning of course)...
so the question being..why does the b16 head flow better than a gsr?? someone else told me that the gsr head has better combustion,and the cams are better for FI....so correct him if hes wrong.

Well, to completely honest with you bro, the diffrence between the flow characteristics of the GSR and SiR heads are minimal....maybe almost non-existant. But IMO, spending more hard earned $ on a GSR head for your application just doesn't make any sence. You can pick up an SiR head for about half the price and have the exact same performance (maybe even better in some cases) than the GSR. Here is a link of some pics of GSR, SiR, And Type R heads so you can see the subtle diffrences between them.
Heads
In terms of cams, for your setup, the GSR cams will work perfectly fine. There are plenty of 500hp+ cars running stock GSR cams. They are better for turbo applications for many reasons including their power curve being geared more towards low and mid-range power...unlike SiR cams which are designed for High-revs. If you can make your turbo more efficient at a lower RPM, then the better off you'll be.
So for you, an ideal setup would be a B16A head with GSR cams. All Honda, easy on the wallet.
