B20 > ALL
I can go through 4 B20s and still have enough room left over to buy a turbo kit and get tuned for the price of a K series motor.
this is nothin but the truth, if you got 8 k laying around just for a k swap in a crx then go for it but as for that goes a turbo B-series will get the job done. ITS ALL IN THE TUNE!!!
