The engine as it ships from ford will take about 16 lbs of boost so a simple boost controller is all you need fish tank bleeder style works just fine.
Also using good fuels helps alot. Still not aweful when stock. Its double a honda civic in case you didnt notice.
Svo was one of the cars shelby put his name on. Quad shock konis from tje factory with lots of other goodies light weight control arms one of the focuses was 50/50 and unsprung weight also had 4 wheel disc.
I would skip the stroker kit unless you want more than the 300 hp. They will make 300 pretty easy without the stroker. 2505 stroker is a nice kit and will make some great power. 400 hp on the street is not impossible but will take a built bottom end and much larger turbo than stock.
