Can this be done safely? (a little dreaming)

makes sense. now that that has been discussed and decided that a) the haltech really doesnt need tuning at 8psi and b) this kit will not destroy anything major at 8psi daily...
lets talk about what turning up the boost to say 12 would do to race every once in a while.

(jacked) not to thread jack but have you guys picked up the newest issue of turbo you should,I did and they talk about how to keep the turbo and your engine safe they also say that you should cryo your turbo and basically everything.

I wouldn't go over 8psi..Unless you plan on running racing fuel! And i am not sure of this..but the standalone highboost offers doesn't have knock control/aka if the engine is detonating..for whatever reason..it will not retard the ecu/pcm..
I know..that before i turn it upto 8psi..for daily driving..i will be investing in a J&S safegaurd!
And about driving habits..it's best to stay below 6k or redline! To many engines have blown when the user/driver..goes right to the rev limiter (msp not included! those just blow up as soon as you turn up the boost
)
And about the tranny..just don't dump the clutch..and when shifting into 2nd..be gentle..other than that..bang out the rest of the other gears..that's what i do!
Oh and lastly..don't boost very long in 5th gear..aka no trying to hit 140 in your p5 and keeping the needle there(Especially if you have passengers)! Added weight + high speed runs=Boom!

Well expect a drastic decrease in mileage..especailly if you drive at 75-80mph..b/c it's very hard to stay off boost at those speeds...as soon as i push down on the gas..i immediatley hit boost! Just the other day..i took a trip over 1hr..on a highway..and i tell you..every time i looked down at my boost guage..i was in boost! Unless i used the cruise control!
The problem with boosting in 5th..is when people try to do high speed runs for a long time..in other words trying to do over 100 for over 10-15minutes..which is allot of stress!
But on a good note..i never have to downshift on the highway..when passing someone!

once you get up to speed you wont be in boost unless yu give it a more then say 15% throttle.. I can easily cruise at 90 without going into boost.Matthew said:
3 weeks ago i went out to pittsburg ~300 miles each way. I avg. 33mpg including all the around town and traffic i sat in.
here is my opinion
any time you make more power you will kill the lifespan of the motor. from what i gather from this board the protege is pretty weak all around for the added power output. to upgrade everything and spend over 8 grand is alot of money.
my friends car is 97 nissan 240sx
installed 6psi turbo kit. power increase was ok.increased to 8.5 psi was a world of difference. everything needed to support up to 10psi. year later burning oil and 1cyl loosing compression. he did have a couple of overboost problems to wastegate line braking. bad location on the external wasgate which would melt the hose. all this on a stock motor.
my last car 91 volvo 940 turbo
bought it with 150,000 miles. stock boost is 8psi. turned boost up to 15psi with some other mods. ran it for another 20 thousand miles and no problems.
volvo makes a pretty strong engine. i did rebuild the motor with forged pistons and other stuff made even more power. then the tranny went. no big deal but expect to break things when you make more power. and yes it was quicker than my msp.
i didn't buy my msp to have really quick car. just wanted a new car with some power and some simple upgrades.
if you can't afford new sti or evo than i would research and find a car that is all ready turbo and can support mods.
