opps lol I don't think I have ever done that

Yeah I agree with ^^ this guy (sohcrxturbo).
Straight line:
The wieght difference between B and H series isn't enough to really worry about with the potential of the H22. K series is going to be almost double the cost though and really the same power as the H stock for stock. Although the K has alot more potiential and would def. be cooler.

Auto-x:
You can actually build a very nice D series! It saves ALOT of wieght and I have seen several 180 whp setups for less than the cost of a b16 swap. And still stay in the 2000 lb range.
