ls:vtec/b16???

[speedminded]

why not a gsr head/ or itr head????

because the pistons would hit it and cause damage.....I would start off with a B16 but I like the ls/vtec because its more power for the money which can be built for around the same price. B16s run for about $800 or what not. All really depends on what you're trying to go for.

The valve clearance wouldn't be any differant, it's just the b16 head is better all around compared to the GS-R (P72), better flow, more & better parts availability, etc. and the ITR (P73) would be fine but initial cost would be alot more...that's money that could be spent on upgrading the valvetrain, cams, and/or porting. on the B16.

The main thing is the engine management...something most people look over. Stock ECU and a piggyback controller is fine but there is so much more you can do with a standalone unit. Uberdata is cheap and Motec is crazy expensive....spend $6,000 on the complete Motec setup on one of the Honda Challenge cars. I'm really getting into the fine tuning aspect of engine building...spend a little more on a good setup and you can safely release more power while remaining reliable.
