I recently moved up by stl frm down south and by chance bought a 91 Grand marquis for $1. Thats right one dollar. Lady was gonna haul it off for scrap, it belonged to her nephew who gt a new car and gave it to her and it sat for 3 years. I had done bought it before I even saw it (be dumb nt to for a buck) I gt to the car and checked it over. Solid body, no rust, clear coats faded, vinyl roof was cracked. I gt in, hit the key she turned over a few times and fired up. Ran rough def needn a tune up. I took it to my shop popped the hood and saw tht she had potential a 5.0l 302 efi. I pulled top end apart and it had hydraulic roller rocker, aftermarket lifters pushrod a bigger cam and a lightweight aluminum driveshaft I cleaned it up new gaskets seals fluids plugs wires new cap and bug and half bottle of Seafoam for good measure and some ol 15" kragers wrapped in mickey radials I had sittin up on the rack. She fired up first hit and drove great. glided down hwy. I try the air, no-go which brings me to my point. I wanna tear out the a/c system and turbo charge it. I dont have much turbo knowledge, bt my f350 is turbo and utilizes the blow thru method instead of the blow off valve and intercooler, I want to run the turbo on the marquis the same way. Wat do yall thnk?

 

Surprised this threads untouched there is plenty of Foxbody builds on turboforums. I would start with messaging some of those regs buddy up with someone who has a 5.0. Definetly a heavier boat to get to boogy down the track but that weight could work in your favor as far as hookin up is concerned. Good Luck

 

for a 302 look for a 60-70mm compressor inducer turbo,, your diesel turbo may be on the small size
