vw and porche are the same engines well the old 1s are u can shot aboxxer 4 engine str8 into the back of a 55 oval. or a scooby engine with adapter kit:P
personally, id like to stuff a bit more into a Lotus. use Bugatti's theory, double the engine, double the speed. so we need a v8 and some goodies and that thing would fly!
bad ass bug man and uh erik the w16 in the bugatti is also done by vw lol i dunno if they do the one for bugatti but they do do one themselves and i know they were one of the first to do it
Take an early 70's 240Z and drop a Ford small block V8 into it. The best part is,... they fit the engine compartment perfectly. I know this was compleatly unrelated, so i'll post it for relevency.
