Hey i have been doing rearch on this for hours days but i need the opions of u guys what head is better the b16 the b18 or type r....i hear the b16 and type r are the same almost...also a type r mani will bolt on to a b16 and is cheaper then the b18 which i hear sometimes leaks...so which one has better CR? and overall which is better you guys think ...it looks like b16 so far
Also i have a 1996 rs

 

B16 head, i have heard more then once, flows better then a b18c1 (gsr) head.. this is not something i know for a fact , so dont quote me on it. But i do think the b16 head also will be less expensive then a b18c1 head because of the availability of them.. b18c1 parts are becoming sparse and more difficult to come by.

 

nice sounds good but does anyone know CR...im thinkin im gonna go wit the b16

 

A gs-r head will give you more compression guaranteed. I think a b16 head is a 42.7cc chamber while a gsr is 41.6cc. If those numbers aren't exact they are pretty damn close.

 

ok so it appers that they both have good qualities....B16 better flow,matchs up good with any type r stuff, eazy to find, cheaper........B18 better CR
now i wonder which would make more hp becuase the compresion is better int the b18 would that make more hp then the better flow of the b16?

if u got a thinner head gasket AND OR if you got the head milled it would raise the compression on the b16.. you could do that with any head but being that the b16 seems more easier to get a hold of why not do it with that

 

good info. i always thought the b16 head had the smaller chamber.

 

Stock a gsr will make more power(but costs more then a b16). Mild head work w/ new intake manifold. The gs-r will still make more power. The differences in flow aren't very much but the b16 does flow better on the top end while the gs-r flows better in the mid range. A stock type-r will out perform them both. With a lot of headwork they will all be about the same.

did u ever hear of a poormans type r? b18c1 block with b16a head. from what ive heard from a few motor builders around here.. the b16 head is more similar to the b18c5 (type r) head then the b18c1 head is to the type r head.

 

Yes I've heard of it. Yes I've done it before. The fact of the matter is that an ITR head is the same casting as a b16 head. But the good folks at honda did thier own little hand port and polish to it. Thus making it flow even better. The compression ratio is still about .2 lower then a gs-r head though. And an ITR intake manifold flows a lot better then a GSR manifold. A b16 head with an ITR intake manifold will out perform a stock gs-r head/manifold. But with a skunk2 manifold on your gs-r you just made up for that shortcoming. I mean seriously we aren't talking about 15 horsepower differences here with these setups. We are talking maybe 3hp compared to the other one. They will all perform close to the same. And it obviously depends on what kind of shape your head is in to begin with.

 

Thanks guys for the info im gonna go with the b16 now ...i let u guys know by the end of the summer how it went

 

good luck

the site is currently down for new update. They bench flowed the b16a vs the B18c1 stock and the GSR head outflowed the b16a stock! Then they did a mild port and polished on both the head and the B16a outperformed the B18c1, not a lot but just enough. I recommend both head it's just how well you built it
