ive got a mk4 platform beetle with an aeg and 02j ive always wished it was a 1.8t. im looking for a ballpark figure to do the complete swap to see if its more financially smart than trying to boost my turd. ever one says it is id really just wanna be able to fry the tires atleast most of the way through second. im thinking the 1.8t is the smarter option but is it more cost effective. id get a 180 or 225 motor. doesnt the 225 come with a k04? or some variant of it. id keep my tranny. i believ minus a couple things of ducting and airboxes all the parts can come from one car if i can find on mostly intact.
