Is it possible to swap out the naturally asperated engine in my '87 for a twin turbo engine from a '93? if so, how much in modifications am i going to have to do?

Its a pretty straight forward swap, especially if you use the TII transmission.



You can order the swap mounts off my website, click the banner in my sig

So different mounts and it will bolt on? Even tho I i'd be using a 3rd gen engine, tranny, ECU, and wiring harness in a 2nd gen body?

Using the 3rd gen tranny requires a custom transmission mount. I dont sell that mount, and I recommend using a TII tranny anyways.



This is no Honda, you can expect to need custom oil cooler lines, radiator hoses, and plumbing for the intake, exhaust, and intercooler and a fair amount of wiring work. Its an involved process, not something you just slap together in an afternoon.
