I'm curious I've owned a few vehicles with throttle body injection. One was a 90 s-10 with a 4.3 and my new one is an 88 commanche with a 2.5

Is it possible to add a turbocharger to this...i woudlnt know quite how to do it on a setup like this.

 

If it has a fuel return line and a fuel presure regulator that has a vaccum port, then you can use a "FMU" it will add 12psi on fuel presure per psi of boost. These are only good for 6-8psi at max, and they aren't the best thing to tune a car with. No less they do the trick, MANY turbo kits use them as well as my friends vortech s/c for his 5.0 stang.. They cost about $100.
