hi, I have a 95 stealth tt with a cone air filter and crank pulley. I want to know what the max boost is and what is safe.

Don't go past 14 lbs without sufficient fuel upgrades and logging tools.

My $0.02: If you're going to add a boost controller, go ahead and do a vacuum reduction. Vacuum Reduction - 3SI Wiki

+1 for vac reduction, and maby even clutch/brake booster delete. It gets rid of a hardline on the firewall and that big ugly tank next to the passenger SMIC. Pick up a set of EGR block off plates while you're at it.

And don't the stock turbos max out at around 17psi or so? Wouldn't any more boost just be blowing hot ait into the intake?

Sounds like your new to the platform. Read up on Stealth 316 Home before you start modding.

i never hear of anyone boosting past 14psi on stock 9b turbos. search the forums for a while and youll learn the basics of the platform. its worth it to read old posts and search when you have a question
