I'm sure this has probably been asked before, but what the hell...

Can an SRT-4 Motor swap be performed on a non-turbo eclipse/talon. They already have the N/A 420A motor.

I know the older gen neon guys can pull it off. This may be a cheaper alternative to the Evo motor swap. The 4G63 is the more superior motor, of the two. But that SRT-4 motor is definently not a slouch.

What kind of numbers are you looking to lay down 305DSM? If you're looking at the 300-400hp figure, the SRT motor is more than capable of pulling that off, and the motor is probably considerably less in cost. I guess it would all come down to the ease of installation though. Whichever of the two would swap in easier (less fabrication required), would be what saves you the most money/time/headaches.

Good luck with your future plans.
