They are ugly
Quality. Chrysler came out with the 2.2 Turbo Chargers back in te 80's, and while they were quite peppy, they sucked for reliability! My buddy did like 3 head gaskets in one year!
It will be fast for a 4 banger, and I'm sure with a Tubo already on there it will be easy to crank the boost, but I don't think the car will take it.
There is definately a performance war going on right now, and it is only making our mustangs faster
