ive found a really cheap 97 gt in my area, the only down side is that it has 2 blown head gaskets, my freind has a 03 2 valve pi engine in his shop he pulled from a car with 60k miles that i can get pretty cheap.........how much work am i lookin at to get this late model engine in this older model car? alot of bs? or can i just use the harness from the 97 engine and eveything plug and go?

I have an 03 engine in my 97 too. Its the same as putting in a 97 engine but your going to use your 97 wiring harness and coils. You will also need to use the 97 alternator. It to me a day(morning to night) with my buddy and I. While we had my old one out we sent the fly wheel to be re done and a new stage 2 clutch. We also put long tubes on it so we dropped the kmemeber...The swap is the same as the 97 engine.

what about how the 03 motor has coil packs. is tht all gunna work with the 97 set up

Just swap the 97 ignition over

oo ok i just thought that the heads were different and where the coil packs screw down and all that

if i were you i would get that motor take the heads and intake off do the pi swap its going to run better than the 03 motor because of the increased compression.and then while you play with that build the 03 motor and drop it in when yourdone with it

if anything id want to put lower compression pistons in the 03 block, b/c i plan on going s/c

you have to use the 97 timing cover on it and your 97 accessories
its a pretty easy switch though. Cams and ported heads anyone?

so in other words i would come out better as far as the money and time spent working to have the heads on the motor in the car presure checked, and install some new head gaskets.....and maybe some cams while im at it?

4.698GT

yes, but i am also talking about getting some porting done to the heads while you have them off. It will benefit the cams if you have the money to do all of it.
