Need help...Swapping 03 PI engine into my 98GT

hey

Hey You should do a search on this at modular department theres many people who have done it. Right now im in the process of doing it im basically done. I put a 2002 gt motor in my 98. You use your original harness,spark plug wires,coilpacks flywheel if you want to use your 98 clutch, fuel rail because the new ones have returnless and are car isnt setup for it. Some people say to change the front timing cover so you can bolt on all your accessories from your original motor but alittle customizing and you can bolt everything on the 2003 timing cover. You will also have to cut a few wires on your original harness and replace them with some clips from the 2003 because some of the accessories have differnt plugs for example (alternator)
You will also have to have the second sensor from your old engine taped into the new motor because the new motor is setup for one sensor. Most people tap it to the aluminum cross over. I was lucky and for some reason i had a crossover on my 98 and i just swapped it onto my 2002 motor. The one bad thing is the 2003 isnt setup for spark plug wires so the alternator bracket has no spot for the clips but you can customize that any way you want. Everyone says to disconnect the a/c and power steering from the block when removing the old motor and then bolt it back onto the new motor when you drop it in because it bolts right up and you dont have to discharge the a/c and drain the powersteering. A good idea is to add some aftermarket headers while the motor is out. Thats what i did because its so much easier. Um i cant think of anything else but im sure ive forgot a few things. But you should go to modulardepartment.com and go to there forums and do a search on pi motor swap. I hope i helped alittle. If i can do the swap anyone can.

oh yah i dont know if you can use the computer but i just ordered a superchip and had my computer tuned to it

u can use the ac and power steering but you have to drain the power steering and discharge the a/c and recharge it later

Why are you swapping the entire engine? You just need the heads and the intake

I would rather have the whole engine that is probably in beter condition with lower miles and a beter compression ratio. Especially if he wants to supercharge it later
