I just built my engine eagle rods probe pistons (9:1 compression) ported head t3/t4 turbo setup 42lb hr injectors stage 2 spec clutch and aluminum flywheel full 3in turbo back exhaust. I was wondering what amount of boost would b needed and what would b reliable for everyday driving too?????

1st 42lb Inj are far to small for any good boost , you need to change then to 60lb

You need a good tune from some one that has tuned the SVT with Turbo many times
Depending on the MAF you have you may need a MAFia

You need a J&S safeguard

You need a wide band 02

Depending on your turbo , turbo kit you engine built right should be able to go to 300 easy if thats your goal , most kits/turbos take 16 to 20psi to get to 300

I do remote tunes for the SVT with turbo for 550.00 and that comes with free updates as you up the boost or change mods

Tom

can't a svt focus do 300-320whp safe with the stock motor and a nice tune/turbo kit?

its either 300 or 350 for the engine and tranny. I can't remember the exact since I'm all motor :(

It takes between 17 and 19psi to make 300whp with a stock intake manifold.... you also need a Boost a Pump.
