Sure no problem....just look at it like this: a 4bt is exactly the same as a 6bt minus 2 cylinders. Now, that being said there are 6bts making well over 1600+ horsepower which is 266 hp per cylinder. More of the moderate 6bts will be in the 600-700 range which is still 100 horse per cylinder...which would net you 400 horse on a 4 cylinder. Most of it can be achieved for 1500 bucks or so after you get the motor. It involves injection pump work, valve springs, injectors, and turbo mods.
