im kind of new to all of this stuff but i was wondering why people put a b16 head on the gsr block

what kind of power would i gain or what is the purpose of doing this swap

pro's or con's????

 

People mostly do it because the b16 head flows the best out of any honda bseries head. The ports were also designed to make the most torque. HP numbers will also different from car to car and depend on the tune.

 

alrigt thanks a lot. anybody got anything else?

is there any bad side of putting a b16 head on a gsr block? like wiring or installation fitting or anything

what?

the reason im doing this build is because my stock b16 motor spun a rod and i picked up a gsr short block for cheap.

what kind of power would i gain or what is the purpose of doing this swap
i'll let you know when i get it dyno tuned next week or so. more displacement=more power.

 

alot of people do the GSR short block with a b16 head. Poorman's Type R. (type r uses the pr3 / b16 head casting)

there's alot of debate about the b16 vs. GSR head.

yeah let me know what kind of HP gains or losses you get on you dyno thanks

there's alot of rebate btw the b16 and b18c heads. i heard the b16 head revs alot better than the b18c. dont know if that's actually true or not.

 

Both heads have been shown to flow virtually identical numbers, stock, so there's no real advantage there. Most people tend to run whatever they have laying around or were able to purchase for cheap...seems like there's more Pr3/b16a heads than Gsr floating around. Probably the number one reason why people run B16a heads is because they aren't limited to what they can run for an aftermarket intake manifold like they would be if using a GSR head. Gsr head is usually worth a .2 bump in compression...some people run this head for that reason. The bottom line is that people run either head for their own reasons but I would not say that one head is better than the other in simplest terms.

lol, but true.

 

lol this thread is a mess.

the b18c (gsr) head has a smaller combustion chamber which will yeild u more compression. other than that aside from the quench pads there isnt much difference especially if u plan on modifying the head.

Hey there guy. The ITR uses a pr3 casting (b16 head)

I do realize there are differences.

Differences:

* the green paint by the distributor
* thinner ITR intake valvestem (12% lighter vs GSR/Si valve)
* minor port work by the valve seat in the ports
* dual valve springs on both sides (b16a civic and b18c1 gsr heads have only single spring on exhaust side not dual), notice yellow paint on intake side, blue on exhaust side
* lost motion assembly has a blue dot

"an ITR head is a ported B16A head from the factory. Both are coded as PR3 heads. So they are the same head but the ITR one has had better intake valves, stiffer springs, bigger cams, bigger LMD's, bigger ports, steeper valve angles, some bowl blending work done from the factory."
