you would be suprised how many there are. tophat has built a few 400hp+ rb20 cars. I still see 3 of them on a regular basis because i know the owners. I am know they have sent a few motors out of state from when i use to work there.

its not hard to get 400hp safely out of an Rb20

call top hat and ask for scott.
