Tossing around the idea of buying an ST

[Mongoose88]

Hello everyone,
I'm currently tossing around the idea of buying a pre owned ST. Probably 21 or newer, up to 60k on it. I use to work for Ford when they had the ST focus, fiesta and the RS. I enjoyed those cars for what they were. I've owned a bunch of mustangs, last one was an 04 Procharged Mach 1. I currently have a 2020 Alfa Romeo Giulia AWD. It's a fun car and I enjoy it, but it's low to the ground and the closet dealer is an hour and half away from me. So thinking of trading it in towards an ST. I like the 400 hp and AWD from the factory, but I know I'm gonna want more. My question is how much power can the AWD version make before needing the built trans? I've seen a lot of people are running Ethonal, do you have to run that to get good power? Can a 93 tune, cold air and exhaust give me good power? Not looking to race it but would like to surprise a few people when leaving cars and coffees. Thanks for any advice

You can get into the 11’s on a ZFG 93 tune and intercooler. A little further if you add catted downpipes.
IC, DP’s and a ZFG E50 tune can get you into the mid/low 11’s.
Things like cold air intakes, cat back exhaust systems and other bolts are pretty much all for looks or sound. Even the stock cat back exhaust flows enough to support more power than you’ll ever make.

Thank you. How does the AWD system and transmission hold up under those tunes? I really don't wanna deal with trying to mix fuel, would E85 require all new fuel pump, injectors and lines?

Have the trans fluid level checked since they run notoriously low but other than that nothing is needed.
Yes, HPFP and injectors are needed to run full E85. That’s a lot of money for very little gain over E50 with basic mods. Mixing fuel is about as hard as two card swipes instead of one…nothing to it.
