ok ive been told by people that a head swap isnt too hard to do, so im deciding to get off my lazy *** and try it out.

b16 heads seem be cheaper then b18c heads, currently i have a b18c with headers, intake, exhaust, mugen ecu, aem cam gears. if i wer to go for a stock b16 head (1st or 2nd gen.. let me know if it would make a difference) would i lose that much power?

the reason for me changing heads is cause the one on my car seems to be dieing, im goin thru oil really quick. after the car is heated up the idle will go as low as 500 - 600 rpms somtimes (usualy around 750) and it makes a clickin sound. wen i rev pased 1500 - 2000 rpms... either the sound goes away.. or i just cant hear it anymore.

im no pro at all on cars, does the clickin have somthing to do with the valves being ****ed?? or can my timing effect that?? just a few things i wanna check before i spend the money on a new head

most people changing heads on a B series have a B18A/B ( which is non vtec ) and put on a B16 or B18c head (Vtec). making "LS-Vtec".
You can put a b16 head on your GSR but personaly i don't think its worth it, because then u would have to worry about reliablilty issues and it sounds like your engine could use some work already. also your head flows better and I think has way more potential than a B16 head, so my suggestion would be freshen up ur current motor and put some cams in or some other goodies while apart.

and the clinking may mean u need a valve adjustment, but take it to acura to get that done right to proper spec.

it would lower compression a little bit because b16 has a larger combustion chamber, and i think the b16 head has more potential because it the same casting as the type r head

Honda Tech

not quit the same casting, all b18 have a taller head which would make it a fair bit diff. the potential would prob. be in the mass amount of parts u can get for the b16 head. but the gsr flows way better than the b16 from factory, so adding to that would give u a strong advantage over the b16 head

Project_Z

ur on drugs lol, the b16a head and the b18c5 are from the exact same casting thats just a fact. b18 and b16b,(it just being a destroked b18c5) are a bit taller overall. the b16 has the advantage cuz it doesn't have gay butterflies on the intake manifold. b16 head has more potenial thats why they based teh type r head on it

leave your head alone and do some internals or something turbo it pistons rods ect

the b18c head has the sorta triangulated cumbustion chamber.
the b16 head has a typical dome-shaped combustion chamber.
by putting the b16 head on a b18c block, you'll lower your compression by 0.2
doesn't sound like a lot but, it makes quite a difference.

stock, the b18c head flows better but,
the b16 flows better if your motor has work done to it such as cams or head work. you can also mount the larger/shorter runner type-r manifold on the b16 head but,
not the b18c head.

the only difference between a type-r and b16 head is that the type-r gets a light port job from the factory.
to me it makes more sense to get an older b16 head,
rebuild it with new valve seals & guides & get a real port job done.

there aren't any reliability issues with switching heads though,
especially since you'll be lowering your compression.
it's a straight remove & replace.

if it were me, i'd wait till i could afford to do everything up right as the problem that you might be having with your motor is in the bottom end such as leaking rings or scored cylinder walls.

good luck,
JAY.
