complete motor.Came outta a 02 gtp. My question is...will it fit and how much difficulty,is
involved with the swap?

by the time you pay for that other motor and go through all the work and get all the kinks worked out it would be cheaper and faster to just buy a gtp.

thing is...the na/3800 I have in there ran hot and is no longer any good. So I have to replace the engine anyway. Figured I'd jus upgrade instead of going back original. I'm can get the 3800 Sc with tranny and pcm,for 2000. I'm jus wondering,will it drop strait in and bolt up? Whats the diff between gtp and base besides engine and exist?

it will bolt straight up but u have to keep in mind the supercharger if ur grand prix wasnt set up for it u have to try and find the wiring harness with it built in and change the whole harness or go aftermarket sensor to monitor ur boost

Buy ''L67 swap'' kit from Intense Racing.com or ZZP3800.com(needed are the supercharger bypass connection and MAP sensor extension connection. 3. The supercharger bypass connection goes as follows; On the PCM, undo the CLEAR connections from the PCM and locate PIN '77'(every connection is numbered from 41-81) then with a needle, poke through the orange rubber seal, push PINK wire with pin into PIN 77 socket, connect GREY wire to ''power-on'' source(alternator) then, using electrical tape, cover open wires. 4. Set L67 engine on subframe, attach torque converter to transmission, attach transmission to engine and secure transmission to mount and bolt on the nuts. 5.
