before raising the boost, invest in an exaust, filter and intercooler.

stock boost is 6 or 7psi once you have upgraded as above move it to 12-14psi.

yeah i was planning to get an exaust and filter u talkin bout a frount mount intercooler i was thinkin bout that to but not to sure of cost any help there?

Even though the cooler would be ideal, i "personally" feel that it is not essential at that stage of the mods.

MY 2c

PS: Once you fit a cooler you will need a SAFC or an aftermarket ECU to re-tune the a/f ratios. When i first got my fmic, on high boost, on a cool night, the car would back fire, loose power, etc., with the facory ecu. (Just my personal experience (not professional advice)

Stock engine can generally handle around 18-20psi or so, which is more than the factory turbo can provide.

Also depending on the turbo, there is a cutoff in its efficiency where more boost doesn't generate any more power.

oh ok thanx every 1

You can run stock ecu with aftermarket intercooler fine. You'll need the upgrade ecu when the boost goes up, or it will run rich. Your car ends up feeling slower!

I personally wouldn't be running anymore than 11psi thru a std turbo and std intercooler especially with summer coming. Sure you could run maybe up to 14psi but your then much closer to lots of things going wrong.

The difference between 7psi <-> is ~15rwkw which is enough for you to feel the difference with in the drivers seat but you'll be over it within 2 months.
