2001 spyder gs engine swap
 

would it be worth it or even possible to do an engine swap from a gts or a gsx or 3000gt vr4 or lancer evo? plz help need to beef up the spyder

no , no, no, and partially no.

You have one of the better engines of the 3g line that can be TC'd and run around 10-12 psi on the stock block. Also alot of people will convert to an evo head swap (which is why i said partially) to get alittle better topend. But i would stick with the motor you have and if you truely want to spend the time and money to Turbo it. But be prepared to spend around 5k at least.
