you are better off just getting a V8... you will only be able to get as much power as the motor can handle.. with everything you can do to a V8 (unless you spend big bucks on a procharger) then you can double that potential with a V8

So what is a m90 swap? I seen it on youtube and dude pulled on a guy that did have a v8 motor? And also i heard thru the grapevine that i can use a gxp supercharger out the Pontiac is that true?

You will be in for quite a project, here you go. YOU'LL NEED THESE PARTS... -Eaton M90 blower (off of a 89-95 Thunderbird Super Coupe) -Super Coupe Blower top (often refered to as a "blower hat") -Super Coupe Lower Intake Manifold -Super Coupe Inlet Plenum (connects the throttle body to the blower) -Super Coupe Air Intake Tube (you'll use this to connect your 94- 95 Mustang GT throttle body to your stock V6 Mustang MAF) -94-95 Mustang GT throttle body (Super Coupe throttle body WILL NOT work with the Mustang throttle cables!!!) -Super Coupe Upper Intake Manifold (connects the lower intercooler tube to the lower intake manifold) -Super Coupe Thermostat Housing -Super Coupe Jackshaft Pulley Bracket (accessories bracket that mounts on passenger side head) -Super Coupe Power Steering Pump Bracket (accessories bracket that mounts on the drivers side head) -Super Coupe Crank Pulley -Super Coupe Water Pump -Super Coupe tensioner pulleys (for accessories belt, jackshaft belt, and blower belt) -Super Coupe Injectors (89-93 Super Coupes had 30lb/hr injectors, 94-95 Super Coupes had 36lb/hr injectors) -Super Coupe Fuel Rail -Super Coupe throttle cable bracket (you will have to use the base of the Super Coupe bracket and weld it to the end of the Mustang bracket) -94-95 Timing Chain Cover (if you have a 96-98, you'll need either a 94-95 Mustang OR a 94-95 Super Coupe timing chain cover) -Super Coupe Intercooler -Super Coupe Valve Covers -Super Coupe coil pack bracket (will probably be already attached to your Power Steering Pump Bracket) -Super Coupe Throttle Position Sensor -Super Coupe Throttle Position Sensor Pigtail (needs to be soldered into your mustang wiring harness) -Super Coupe Intake Air Temp Sensor -Super Coupe Intake Air Temp Sensor Pigtail (needs to be soldered into your mustang wiring harness) AND DONT FORGET TO... -Replace the Super Coupe water temp sensor with the Mustang water temp sensor (this way you can use as much of the Mustang wiring harness as possible) -Bend the brake line (the one that is the closest to the front of the car, the one that is closest to the firewall will clear just fine) that comes out of the master cylinder towards the rear of the car to make room for the lower intercooler tube.
