you need to do some research before you try this. I speak from experience. I know the boost bug is bad, but how do you feel about sheeling out $3K fora new forged motor?
Your best bet (if you dont want to buy forged pistons and rods) is to buy a CAI, bigger catless downpipe, full 2.5" exhaust, and a good FMIC...this should raise your boost about 2psi automatically. Also have the dealer do the "flash". This will bump thie timing a little and will yeild some power. With these mods done you will be faster and still safe. Do no more unless you plan on building/rebuilding the motor.

dude 25 lbs should be fine, just kidding seriously I agree whith what roddimus said, unless you tear it down and go forged internals, lower compression, stud the block, reprogram the ecu and so on but that will cost quite a bit oh and i mention a fmic? and then if the axes hold up and tranny it will make for one sweet ride, i know i left out alot more but thats all i can think of right now
also say bye bye to your warranty forever

Don't raise the boost...You will void your warrenty...But if you really wanna get some good HP...Invest in:
1. A 3" Exhuast..The bigger the better the flow!
2. A large downpipe..atleast 2.5"!
3. A FMIC!
4. Upgrade the EMS/ECU/PCM
5. SMaller rims (Lighter means faster)
6. Lightened Flywheel (Spins faster & revvs better for turbo car)
7. Under Drive Pulleys

Ive heard that you can go as high as 7 or 8 lbs of psi on stock internals, but anything over is not recommended. If you're going to do that then you ought to invest in cams, pistons, cam gears, bigger injectors etc... I plan on stickin with a stage 1 kit by whoever I purchase from. Its my everyday driver and I don't need to be streetracing anyone.
Not to threadjack, but where can one go to get a lightened flywheel for the 1.6 liter Protege? Someone on this board or another said he found one, but its listed for the 1.6 liter Miata. Will that one fit on the same displacement engine Protege?

I agree with the rest of the guys about not raising the boost. The gains are only going to be temporary, because no one really knows how long the engine is going to last. Everyone thinks if I add just a little more, it'll be just better. With no forged crank and pistons, too much boost makes any engine a time bomb. If the engine held up, the drivetrain would probably fail soon after. Here's the deal, so you get 200 horsepower by 10 PSI boost, (approximately) which equals 1 second in the quarter mile. But a good driver can make that up at the light by proper driving technique with no risk of engine damage by overboosting. Get a V-8 engine car and put on a Vortech supercharger if you want big horsepower. A "Speed" handles awesome and that's its calling card, not quarter-mile times. Learn to drive a "Speed" at its limits, and you'll never want to mess with boost again. It's ability to run at incredible speed on mountain roads is awesome. This car is no joke, just ask the BMW Z4 owner that was shocked to be followed so easily, by that little yellow car.

1. Cams & cam gears..will not do anything..to help the car to boost higher..
2. Bigger injectors are not needed..i have the same injectors..in my p5 and i am running a t3 turbo..at 6psi..which is equal to about 10-11psi..on a t25!

Im not sayin that its necessary, but it is recommended though. Most kits come with all the extra parts needed to run a PSI higher than 8. Most of the time bigger fuel injectors are included. The kit that im lookin at has the bigger injectors included.

Well..It's not that i am only going to run 6psi...
I am waiting to get some more support mods before turning up the boost!
I will have my Ic installed in about 2 months..than upto 8psi for daily driving!
