Hey guys,
I'm trying to collect some info on what I would need and what I wouldn't to set my 89 GT up for a turbo. It's bored .30 over and that's pritty much it as far as I know. Bottom end really hasn't been messed with two much. It has a stock automatic transmission with a shift kit and 373 gears. Suspension is stock except for eibach drag springs. It's got an H pipe with flowmaster 50s and shorty headers. MSD ignition. If you have any helpful information it would be greatly appreciated
You would probably be more happy with a nice hci combo if your car is stock, the 89s already have forged pistons, as long as you keep it under 10 psi you would need something along the line of 40# fuel injectors and a 255lph fuel pump. Once installed you would need a tune so your mass airflow meter is set according to your injector size. As long as you got the fuel and a good tune then you would be okay SORTA, on boost can make your car run warm. Upgraded radiator and cooling system is recommended, also blow by can be a problem if any of your rings are worn out. If you are building more of a drag car, a higher stall converter would help your car leave a LOT better
Transmission - No, probably not. Depends on the HP you develop.
Remember most of the 5.0 transmissions were designed for around 300 HP. Some a little more and some a little less. If you throw an extra 100 HP or more on them, they are going to fail.
Engine - No, not without some upgrades.
For 12 PSI you should start looking at replacing the rotating assembly with all forged pieces, adding a main & valley girdle and above all be very conscientious about keeping it tuned properly.
You can usually get by with 6-8 PSI on stock components.
12psi might be a bit much but it depends on what motor upgrades u have
