Hello guys n gals! First off, I have been following all this turbo stuff for the N/A XF since buying mine. I wanted to just throw out a little bit of information that has been bugging me since seeing all the differences posted in the 3.2L N/A v the 3.2L SRT. Has anyone actually set the different parts from each side by side and looked into the physical/metalurgical differences between the two? The reason I ask, I had a 3.8L in my 89 Buick Park Avenue that needed two of the three coil packs. The local Buick dealership looked up the price for the Park Avenus ones, and they were over $110.00 each! I went home and called the same dealership and asked for the coil pack price for the 3.8L LeSabre (different part number) and to my surprise, they were just over $60.00 each. As a point worth noting, the coil packs are electrically and mechanically the same. They both swap between each other and btw the generic ones were almost half the cost of the one for the LeSabre. Point I am making, just because it is a different part number, is there truely any difference in them?

Has anyone put the S/C from the SRT on the N/A? If they did (understanding a few mods in brackets/heads/routings), how did it work? Anyway, I'll understand being flamed like crazy if it's already been done and researched already, its just I cannot get those coil packs being the same except the part number and price for the 'higher class' Buick. Peace-Out!
