Hey just purchased my 1993 stealth rt tt and forth first mod instead of out right replacing the stock turbos I was just going to buy a boost control was just wondering what best brand for the stealth would be and how much boost from each turbo can the engine take safely.

Thank you

 

You use one boost controller, to control both turbos. Without any other fuel modifications, you can only safely run 14psi.

boost controller brand boils down to what you are willing to spend, and what you want. There are dozens upon dozens of boost controllers available.

 

Ok so basically in order to get what I want I'd have to replace my fuel rail and probably upgrade my intercooler and when you say 14psi that's the stock 14psi from both

 

your car runs 9psi stock. The stock gauge does not measure boost accurately what so ever. If the gauge is pegged, your car is running full boost, whatever that may be.

Why are you replacing your fuel rail and intercooler? Those don't need to be replaced, regardless of what you are doing.

What are you trying to do to your car?

 

I'm looking at getting a boost control to bring the cars psi to max I was not aware it ran 9 psi stock that is good to know thank you. Some day I would like to replace the turbos for bigger ones but as you can tell when it comes to boost I don't know a whole lot so I don't know what needs to be replaced to safely run say 20 psi total 10 psi from each turbo.

 

Psi is not split between turbos.

Stock boost is 9psi.. that means each turbo is running 9psi... it is not added together, that is just what they push, it's a single system and flows together, and monitored as such.

20psi on stock turbos is not worthwhile for the stress you will be putting on the system. 14psi, and leave it be, until you are ready to dump $6,000+ to install upgraded turbos and the proper supporting modifications.

 

VOLUME is the measurment you need to worry about an example 20psi on stock turbos might only be 10psi on a bigger turbo and there both flowing the same amount of air. keep in mind the amount of miles on the car and if you boost to high you may cause a blow by problem. theres more to building power then just air and fuel. what good is all that volume of air if ti blows rite past the piston rings. you need to do a lot of RESEARCH before you do anything

 

Thank you both of you I will continue to do my home work before I get any thing done
