Unless you wanna blow it up coz your so rich you can rebuild it.

Your car your choice man, if you are gonna do it anyways then listen to the guy in the 2nd post. 70psi turn that sheit up

well of course if i ever did turn up the boost i would get it tuned. i just wanted to kno how much boost ppl were pushing? especially off the stock turbo.

[LuVJuGGs]

stock turbo seems to be maxed at 20psi. 18 to be safe.

Also do you see a big decrease on mpg?

Are you just curious about the numbers people on here are running because you are not familiar with the ej257?

Here is the bottom line.

You will most likely be getting tuned by a professional tuner. The best advice I can give you is to tell your tuner what kind of performance you want and how far you want to push the tune.

Ask your tuner what he would do.

These are not boosted hondas or old 80s/90s econoboxes with factory snails attached. These are highly tuned engines that can be finicky about what you do to them. Work WITH the engine, and you get great payoffs. Work AGAINST it and it'll stat coughing up pieces of pistons.

So don't just slap on a MBC or EBC and cank the boost. And don't take it to some shop that's only ever worked on a couple STIs. Find a shop that has lots of experience with STIs. They will make sure the car is turned right. If you aren't sure about your local shops, ask around and you'll probably get recomendations for your area.

If you want to go faster quickly and easily, get a downpipe or turbo-back exhaust and buy a Cobb AccessPORT V2. Flash the appropriate Stage 2 map and go have plenty of reliable fun. This can be done in an afternoon in a garage.

I'm running about 17.5-18psi now in the higher gears (stock turbo). I asked my tuner for a conservative tune though because I want something that can survive HPDE's. He said it may boost a little more in the winter when the air gets denser.

Mods are:
catless TBE
aps 65mm
3 port boost solenoid
walbro
