B16a with C4 head?


It will work as far as I know but why would you want to do that?

In my opinion the c4 head is totally useless really, not the best flowing head, and the inlet manifold fitment is a total nightmare to be honest! Not really worth bothering!

What, by fitting a C4 head onto a B16 bottom end?

Surely that'll be worse not better!

c4 heads are useless! Hence why people swap the c4 head for B18c/B16B/B16A heads, they offer better compression...etc. In this case he already has a B16 bottom end!


Plus as said your limited to the inlet manifolds you can use, so your either stuck with the multi-butterfly design inlet of the c4 or you have to fork out AGAIN for a Skunk2 inlet or similar.....

For basically.... zero gains.

the c4 head has a smaller cylinder chamber which gives you more compression

I'm aware of that but the gains are minimal then your restricted with the inlet, so your not gaining much at all..... see what I mean?


I've never owned a c4 though, they're good for boost, not a whole lot else.

Well you just said it won;t rise compression now your saying it will make up your mind :nice:

I didn;t say it was a good idea but its the only reason people do it to the b16a to rise the compression a bit

No i said "I'm aware" I didn't say anything else other than those two words.

But if you'd like me to specify further....It'll raise it a FRACTION.... then you loose really due to the inlet design which are shocking.

Obviously the cams are better and more aggressive but he's not mentioned cams, just the head. It's the head/inlet itself I'm discussing here.
 
Any way it's all by the by really as it may be the only head he can get.....

So we'll work on the fact that he has no other choice.


YES they will work together. That's all.

you edited your post about 3 times ;) you first said it wouldn;t rise the compression. then back tracked.

Anyways they are compeletly different heads your better of saving your money and buying a set of itr/ctr cams more gains to be had than switching heads.

I did edit my post yeah :) because I hadn't said what i wanted to say properly. I'm tired haven't slept for about 3 days, so it's hard for me to even think properly at the moment let alone think about engines..... but I am trying.

The chamber's on the c4 head are flat where as their round on a B16, which as you said raises the compression......... but then you loose in the long run due to the inlet design. So the gain is minimal? I personally think its pointless.

See what I'm saying? That's why I edited as I didn't explain myself very well.

You did but in your first post before editing you said it won;t riise compression :nice:
b16a and c6 heads are the same head only for a small port and polish and intake valves and dual springs on the exshuast

Its the c4 tthat is the smaller chmabher
I said its pointless to switch really. just pointing out that some switch off for the compression reason wouldn;t switch meself doh :nice:


You edited it again
haha ok we both agree no point in it lol
 
pointless imo. i would rather put a b16 head on a b18 bottom end.
but yes it will work

I did edit it again....... notice i put c6 mate? I meant c4 so its been edited AGAIN.

Like i said I'm absolutely fooked to be honest with you, I'm that tired its unreal. I don't have words to explain how tired I am. And because I cannot sleep and take tablets to try and make me sleep its even worse..... (I'm sure you understand).... It's quite difficult for me to even think about c4, c6, b16...etc at the moment.

But thought i would try and advise this lad any way. :nice:


That's me now, over and out. lol ... but once more....... its not worth bothering with the c4 head!
 
Im pretty sure the GSR head is the best of the B series for boosted motors.

Rich777 on here uses it on a b16a bottom end if im
Not mistaken.

There is nothing wrong with the C4 head. In fact, if anything the C4 head is the superior B-series head. Flow wise there is nothing between them. The C4 head also has "quench" pads unlike the B16 head which is a bonus.
