can this kit ONLY be installed on the 99-04 PI motor? also how much of a hassle would it be to get it to work with a thunderbird? (i know thats kind of a general question, but what would definitely be needed other than the kit itself?)
It can be done but it not easy. Since I am the first one to keep the coil packs there was a steep learning curve to make things fit and work. I did the hard work now it will be much easier to do. I strongly recommend getting a mark 8 altenater and modifying exactly like I stated.
Do not put this on a non pi motor. My pi motors head ran out of flow at 5000 and the boost started backing up in the manifold.
it took me about 3 months to do but it should be doable in about 2 weekends with help and depending on how fast the machine shop works. I had to figure out a lot of stuff along the way and that is why it took so long.
