You might need some different needles to get the SU's tuned just right on a B20. My PV has a 2.2 liter B20 with a stock D cam (almost identical to the K cam, the K is a 'smog' cam with a bit less duration) and it ran fairly well with the stock needles that came with on the B18. Rhys sold me a couple of slightly richer neeles and it opened up some full throttle high rpm power. Tuning SU's is a bit of a black science, it took me a while to learn how to get the engine to purr with them. Leaking, sloppy worn throttle shafts, however, will stymie most attempts at tuning.

Since then I've put on a set of DCOE 40's which make more power and have better throttle response. So far they use more gas too, but 1/2 of that is probably me just driving it faster. >:^)
