Yea you can put pretty much any engine in it that'll fit. I remember back in the day, i think they used s2000's engines some times. For cheaper you could just leave the stock accord engine in it, lol.
Oh and it uses 1990-1993 accord front subframe as a main part and some other parts from the car. Technically it will be titled in the USA as a 90-93 honda accord. Expect to be pulled over alot
Yea i remember reading somewhere bout the ford engines. They musta changed it up a bit since i looked at it last.
You pretty much buy the kit, they ship it and you find a builder in the US or where ever. I think thats how it works, dont quote me. Their main page is under construction so...
Edit: Seems the best engine is from a prelude, the H22
