I was going down this route, but I ran into a lot of issues. Mostly being what's the point in adding 150 horses if you're just going to sit and spin tires all day and other requirements to make ti a smooth install. IE GT500 Fuel Pump, injectors, Lower Control Arms, tune etc. You can find a Blower for about 4k, but the Pump, Control arms and tune will cost you about another 1000. Then factor in labor.
So I decided to turn 4.5k into traction and efficiency.
So far Short Throw Shifter ($250)
3.73 gears ($400 installed)
Tighter suspension (springs and dampeners and Sways) - (1000 installed)
Bump Steer kit/Adjustable Panhard Bar ($300)
Upper and Lower Control arms ($250)
GT500 Front brake kit w/ cooling. ($1250)
Total: 3900 + labor... (4500)
All said in done with a 93 tune + exhaust, the engine should be putting out about 335-340 hp and 350lbs of torque and all the traction and efficiency you can ask for. Hoping to put down good times and be able to rip up a track all day.
Then a supercharger
