VTiR B18C vs. Type R B18C.

[tinkerbell]

DC2R head = B16A head with factory polish job

VTiR head is unique to VTiR and is not used on any other car. the port angles are different which can help at over 8000rpm (so the experts say)

Terrible One:

B20B with VTEC Head:

Try and keep this thread as close to topic as possible guys, VtiR vs Type R motors

edit: If you do have any other questions, start another thread in the appropriate forum.

this is the appropriate forum?

this is the appropriate forum?

I was referring to this question asked by the thread starter:

Interesting stuff here.

Looks like a VTiR cut is the way to go then. How much can a good Type R box be had for? Shouldn't cost alot if I pension off the VTiR one.

What's involved in a B20B setup? Any links to other sites or threads in this forum would be great.

Toda is doing a deal on New Type R boxes right now mate - Go to the suppliers section.

Interesting that people say the VTi-R head flows better than Type R considering they are the same head I thought (Different intake manifold with dual runner I think for the VTi-R) and that the Type R was simply a mildy ported and polished version of the VTi-R ... Thoughts? Any flow bench data?

I would love to see the dyno graph (want to look at the curve) for that toda motor .. Is it a violent 6000rpm+ line? And what is the limiter set at?

Edit: My bad -- Back on Topic

they are the same head ???

They are NOT the same head.. a Type R head ala pr3 head is the same in casting to a b16a head..
although the peripherals such as camshafts, valve springs, and the head being slightly polished (NOT PORTED ONLY POLISHED)

the p72 is the vtir head.. yes it has a different dual butterfly intake manifold, but the casting is totally different..

the arguments for what head is better goes on and on and on
but worked side by side a p72 can definitely be as good as a pr3 .. no questions asked..

and can be argued to have better high end flow because of the more "direct" airflow for hi rpm ..

The VTi-R also has the smallest combustion chamber volume out of the three; Depending on your application that may or may not be a good thing.

i think most of the guys refer to the casting when they say the B16a head is the same as the B18C7
