Well, since I"m comparing the price of having a b18c1 with type-r pistons, VS having a cooler engine name and getting the ITR block, if you could tell me what to look for or how much you paid for a ITR Block w/pistons......used......

I'm no drag expert but damn, 185whp + 2600 car and 102 mph traps are impressive.

All things being equal as in cams and such. The GSR head with inherantly produce more hp due to a smaller combustion chamber. Thus this raises compression. Also the GSR head flows more CFM than an ITR head. But the GSR head induces turbulence in the air flow unlike the Type R head. Im not sure if the Type R head is better or not.. I personaly believe that the GSR head is better but i can not prove it..

How do you figure the GSR head flows more CFM than an ITR head and produces more power? Do you have actual proof? I don't think Honda engineers would go with a poorer flowing head for an engine that requires more flow than a GSR.

This is Alaniz's comparison of a STOCK B16A head vs. a GSR head. If you look, the B16A head flows better for most of the midrange until about .450 lift. A ITR head is ported well with better valves and valvetrain, which do YOU think flows better???

im getting my C5 block and stuff ready and i was made aware that ITR pulleys (Power steering, alternator, and crank) would be a good idea. just to add something.

may not be needed but may be a good idea, who knows... im just paying king motorsports to do it all for me so i dont have to worry about this shit.

just wanted to fill in about the header. from my very OWN personal experience a B16 header will not work with 1.8Liter motors.
<br>
<br>i recently switched from a 1st gen B16 header to a 94 GSR header on my LSvtec because the B16 header was giving me a bad exhaust leak between the exhaust manifold and downpipe.... because the damn downpipe was hitting the oil pan and thus it was not able to seal properly...
<br>
<br>so theres your .00001% [image]/images/icons/wink.gif[/image]
<br>
<br>(nice post btw Tom)




with my ls/vtec setup i used my old dc sport b16 header <4-1> and it works just fine its a tight fit but it doesn't touch the oil pan

I doubt it only because it wouldn't pass visual, but maybe you could take it to a referee so they could recognize the new block code.
