- Thu Jan 29, 2009 9:59 pm #93085 a fully built ls/vtec can put down some really good numbers .. but if your talking bout comparing a gsr with a built type r head to a stock ls with a b16 head then the type r all the way but i would run a type r tranny with a lsd and 4.7 final drive on both motors. Also the itr head is off a b18 not a b16 that is a ctr head. The b16 head does have better flow charteristics then a type r head but thats nothing a port polish cant fix lol

wrong. Poor mans R is a B18c1 block with a B16a head.


The B18c1 with a fully built ITR head will make more power than a stock block ls using a B16a head.

Tranny has nothing to do with power made, just how fast it accels. Even if the LS/V made more power, the GSR tranny would negate alot of it with better gearing.

- Fri Jan 30, 2009 5:22 pm #93304 LS VTEC isnt better for anything unless you build it for that. Just slaping a vtec head on a stock LS block is the worst way of building the motor. Your still limited to the 7k redline of the LS, and you will have shit for compression.
