anyone here know how hard it would be to drop an H22 into a del Sol? it's a 94 del Sol S, would i need to engine mounts? transmission? anything like that?

 

Do a search. It is the same as a normal civic of the same gen. You will need to buy a mount kit, shifter cables, axles, ecu, engine, tranny, Rad hoses, much much more. Oh yea wire the whole engine too.
It is not a easy bolt in for a newbie to the car world. It is very do-able! And will offer great gains!
