amen to that. but none the less they are unique and fun to drive. i wouldnt throw out the v8 idea either. a v8 fd is also unique but they have there fair share of problems as well. it isnt a simple plug and play process as some would like you to believe. its long and costly, but the outcome can be quite impressive. ive known people that have done the swap and it can be time consuming and again costly. if you got the hook up on a lot of parts then it might not be as expensive as it could be, but still very expensive. lsX motors arent cheap, then you need the new subframe, all the wiring, fuel, custom this custom that and for what 350hp/tq?
either is a good way if you ask me but one is easier then another. go lsX and spend lots of time and money but could easily make that back and then some. go rotary and its a direct swap plus a quick and easy profit.
no body can make this decision but you. either way, FDs rule the school

good luck
