gsr... or a b16.. what u think? And which one wil last longer if the head work is done right?

 

B16

 

boost or n/a? i like the b16

 

b16 or type r. gsr has smaller combustion chamber which will raise compression.

Does that make it better or worse?

Isnt that desirable for an N/A application

 

it really depends on what you want to do with the car. any of those heads will work fine for a daily driver or occasional track car. the best thing you can do is consult an engine builder about what your goals are. they can help you decide what setup will meet your goals. if you want to go na then yes you want higher compression. but you can also achieve a higher compression by replacing internals, which if youre truly building the motor i would hope you would do anyway. if its gonna be a daily driver then you want something that is streetable and not going to drive you nuts. if boost is your game so be it. but if you want a street car than 30 psi is a bit much. just like a 13:1 and up cr/vtec is a little bit overkill.

 

b20 wit itr head. torque n hp

 

B16 or ITR!

Same as a ITR.

Id go with the GSR head, the cumbustion chambers are squared off on the intake and exhaust side, this improves the quench. people who modify PR3 heads sometimes weld the cumbustion camber to replicate this benefit.

 

well wasnt the type r head copied from the b16 head...?

 

Cant beat PnP GSR head.

 

ITR head = PnP B16 head with different cams, valves etc
CTR head = Pnp b16 with different cams, vavles etc

GSR is the best head due to its square combustion chambers = high compression
