Hey guys i've been working on this new build for the poor man's type R. I just want to have suggestions from you guys about my build.

First , i have a bone stock JDM B18C Gsr with just Skunk2 manifold and custom headers.

1st Choice : Gsr head with port and polish , double valve spring and retainers . with b16b CTR Cams. Skunk2 pro series intake manifold and B16a Throttle Body.

2nd Choice : CTR B16b head, complete Type R internals, CTR b16b cams, type r Intake manifold , type r throttle body 62mm, with spoon head gasket.

Please comment your suggestions. if necessary you can post some proof of this build's if you have one. Thanks! Your answers will be highly appreciated.

 

2nd choice but keep the skunk2 pro intake manifold. and a bigger throttle body.. 62 is ight though

b16b head will give u more compression than the b18c head

 

Um..No. Other way around

 

Who did the PnP on the GSR head. That is a BIG factor.

 

Wow! Nice topic here. Regarding head porting who does a good work?

 

You got the concept but reversed the facts;
GSR head has the quench pads and will increase comp vs a B16/TypeR head on the same
Shortblock. At the same time, a stock GSR head casting will typically out flow a B16/TypeR head casting under 5-6K RPM, and the B16/R head will outflow a GSR head from 6K-up. Once you get into ported heads this is no longer a relevant consideration.
I would personally use the head with the port work provided it was done by a reliable source, and then the mentioned Pro manifold and a TB port-matched to the intake.
Typically, a good port job can yield gains easily around 10+ HP on a mild NA B series and allows everything else to work more efficiently and thus makes more power in that way. Everyone and there brother thinks they know how to port Honda heads, manifolds, etc but the fact is that to make any real gains the process has to be done in a very precise manner utilizing equipment that most individuals do not own. Because of this, who/where did the port work and what exactly was done is far more important I would say than any other aspect. A properly ported head from a respectable shop can entirely transform a setup compared to a stock head. Night and day difference, but at the same time a DIY can do more harm than good hacking up ports and actually lose flow and therefore power from home "porting".
