the 4g63 turbo engine will fit in any 1st gen talon/eclipse. u will need all the motor mounts for the turbo engine. a non turbo 4g63 flywheel and clutch is needed, because the turbo flywheel and clutch wont fit in the non turbo tranny. turbo fuel pump, complete exhaust, intercooler and piping, wiring harness turbo ecu. turbo mas. im sure im forgettin more stuff needed also.
i did alot of research on this same topic because im doin the same thing just need the flywheel and clutch, but i had a complete turbo talon so i have everything needed to do the swap
