These cars have blown up at stock boost and some (like mine) have over a 100k miles on them at 13-17PSI on both the stock on the now the Nick modified turbo. It is a total and complete crap shoot on whether or not you will bend a rod, burn a ring, crack a piston or like me sail along with nary an issue (except that damn defective diff) for 4 years now.
So roll those dice, turn up that knob and hold on! :)

13-17 lol your fucked...

13-17 lol your fucked... Um...well not thus far. It has held up very well and in fact I have hit 20PSI with the new turbo and just about shit my pants. I could see my rods going into orbit!
I ran 12PSI from 2000 miles on, then got an exhaust, and an Injen and bumped it up to 13-15PSI. I hit about 103-104k miles and the diff went (while pulling away from a redlight barely moving no less) and I then kind of went apeshit and threw alot of other stuff on. Either way 12-17PSI has been what I have run and I am at about 113-114k miles now. Good milage, runs great, pulls hard and I drive it a 104 miles a day to work and back.
I am not alone in this 505ZOOM, BlackZoomZoom, DiscreetSpeed and Apocman have all been hitting just as high PSI as I have. Heck 505 has a big ass turbo now too.

Not all of us can be factory freaks like yashooa and 505 Zoom. :rolleyes:

[fr0st]

im gonna stick with stock for now.. it pulls more then 90% of the cars on the road here.. which is enough..

[BOOSTR]

If you have a two stage boost controller, keep stage one stock and 10 or less for stage 2. You can go higher, but its not for the faint of heart or for light pockets.(glare)

[dapope]

lol....you seem like someone i would chill with lol...so i am going to listen to you...13-15 seems just fine lol.. thanks

But none of the above said cars ever track their car hard is the key factor.

[Karna]

i am in the exact same boat as you man, new owner, same mods and i want to up the boost (up to 12-13)...but based on looking around i found that you should also add a step cooler plugs and the ecm seems to be very important

[JDM Sam]

The rods and rod bearings are the parts the commonly fail.

They can start from oil starvation and then seize on the crank and throw a rod, or just not being able to handle the increased power.

[yashooa]

But none of the above said cars ever track their car hard is the key factor. Nope. I don't own a "track" I own a street car I never said I was safe.
Read my first post and I told him basically with these cars it's up to God, the weather, the Easter Bunny and AL GORE, SAVIOR OF THE PlANET! As to whether or not an MSP will decide to explode.
I also forgot to mention three of the 5 high boost MSP's are on their second motor D'OH! Not mine or 505Zoom's allthough APOC's car was ok it was just a case of misdiagnosis that lead him to change his engine only to find the old motor in perfect shape after a tear down. It was a case of loose exhaust manifold bolts! Oh SNIZAP!
I have slammed the first three gears to the redline more times than I can count though, and I have been a general holigan. So it has seen very hard street use just not "dumb" street use. :)

I do have a J&S Safeguard and an MPI plus some AWESOME, COME ON OVER WHEN YOU WANT TO HELP ME CHANGE THIS SHITTY CLUTCH, friends who have seriously mass-aged the Nubian with me (cool)
Seriously though Nixypoo,Apocman,Moeed, Turfburn and some others all helped me build this Blizack Mutha Fugga up and I owe them a lot but eitherway my car has beaten the odds and yes it HAS NOT BEEN track attacked.

Word to the wise. I never dicked with the fuel cut until I got an MPI and could add fuel. I hit it now when the car goes lean. Moeed and Linux were over here a couple of weeks ago and we saw it hit 13/1 on the datalog when it cut. So I add a bit of fuel and avoid the cut but again I NEVER FUCKED WITH THE CUT before I could see what it was doing. In the summer I never hit and when it was in the lower 50's and below I would get it some. So the moral is don't fuck with the fuel cut until you can see where it needs fuel.

[dapope]

how do you fuck with the fuel cut

You get an FCD but no way to tell what the fuel is doing.
