b18c block with b16a head

[mo]

guys i've seen people do this when they do a b18c conversion...
is there an advantage of using a b16a head instead of the b18c head?

It flows better, and is closer in design to the ITR head.

Do a search for "LS-VTEC" on most Honda forums and you'll find out about it. You can prolly drop it into a search engine like Google and find out about it too.

I think he is reffering to putting a b16 head on an already DOHC VTEC setup (B18C). Why? Because the B16a head is closer to the ITR head than the B18C head.

B18'B' is the LS-VTEC setup.

this is more commonly called a 'poor mans type r'.
yes the B16a head is slightly more aggressive, but if you go with the 16A head on a 18C block, you will actually lose compression and quite often you don't feel much difference in power. to do it properly it's better to grabs some high compression pistons such as CTR and get the head port and polished and you will get an awesome flowing head with high compression which will rev willing to 9K!

I thought the DC2R motor designation code was B18C?
Obviously I was wrong. So what is it?

It's USA based, but you get the idea

B18C5 & B18C7 are the ITR. When people say B18C, the usually just reffer to the Vti-r

Either that or the DOHC VTEC model... :wink:

[one more chance]

the JDM ITR is coded B18C-R
the Oz B18C7 and Us spec is B18C5 for the ITR.
the VTi-R engine code is B18C2
