Careful with messing with your MAFs and Injectors. You've already blown one engine NA by messing with MAFs and fuel. The room for error boosted is much slimmer.

How much bigger do you need? 42lb/hr high impedence have done 300whp with a little extra fuel pressure and you won't need to get a injector driver. They highest they sell, high impedence, is around 50-55lb/hr though.

What the heck is a 460 MAF? Do you mean a Mustang GT 4.6L V8 MAF? Read the FAQ. Bigger injectors and a bigger MAF = MORE TIMING. The ECU looks at the MAF volts as it's main load and timing calculator. I had 42s and a 70MM MAF calibrated for them and pulled a constant 30* spark advance. More timing = a blown engine as in exploded.

No way should you put the intercooler in the engine bay unless you have a scoop there and have the cooler facing up, kind of a side/top mount. I say hack away and put it in the bumper.

My nitrous run was done only once. We pulled 4.5* of timing across the board and hit the juice at around 4500rpms(a bit late but I was worried about a backfire). Only had a bit of a misfire and still got great numbers on arizona 91 octane and 9psi. My tuner felt the timing was still a bit conservative so after over 10 hrs on the dyno and tired as heck I thought why not. Added back the 4.5* and BOOM blew the motor on the next shot.

Be careful. Doing a turbo on the cheap is easy. But doing the fuel and timing on the cheap will cost you more in the long run.
