hp/1$ the B will be better.

THe K you have listed will cost you $10,000 if not more in parts and labor.

The B wont cost quite as much.

To be honest this is a stupid thread, and the responses from some are even more retarded.

With cams the K series can make good power, Chunky made around 210whp with his ITR pistons and ITR cams in his K20.

IF you are after NA power and price is not a factor, the K gives you alot more room to move around. They are easily capable of 250whp in street trim (meaning streetable)

B Series 250whp is almost not streetable as it is at the limits at that HP level.

If you just want to go fast, Boost a GSR, cheaper than both those.

I wouldnt do anything to a D series outside of a small turbo kit an 200whp. Anyhting over 200whp on a D from what i have seen just doesnt last
