Put it this way, There are tons of people out there with supercharged 4.6L Mustang GT's w/ stock internals and 90% of them always start running into *major* mechanical issues with their engines at around 70,000 miles with the blower on. Forced Induction basic rule of thumb: It's generally not safe to boost an engine with the stock bottem end still in place! Differences in most (if not all) stock engine's internals that come straight from the factory usually vary greatly between factory boosted engines and factory normally aspirated ones... i.e. - forged pistons, crank, bolts, etc.. in order to withstand the extra loads of power that's being put on them from all the extra boost they're receiving via any different kind of forced induction method being utilized.

hmm i think i'll have to go find out the exact parts the rebuilders put in my engine and see if its capable of anything.

Ok so you have a 85 3.8 which had about, what 150 hp? Put on a S/C and you're looking at about 200? My N/A 96 3800 seriesII in my Eighty Eight has 205 stock supercharged ones have 240hp. You are better off getting a newer model.

Oops just re-read the orig post. 125 to 280? I find that hard to believe, but if it's true I don't know which will go first trans or motor.

The condition of the trans right now, it would probably go. But im rebuilding it in september...

Hi speedy266, Hi All
Are you sure these guys are reputable? Those power numbers sounded way optimistic relative to cost. Then I did the currency conversion.
I suggest you reread all the above posts with an open mind, as I didn't see any misinformation in any of them.
$4000 to $5000 dollars US to rebuild your engine to be able to work in conjunction with the blower, and probably an equal cash amount in drivetrain upgrades to make it all work.
After all that you would be badly embarrassed by any self respecting ricer in my locality.
I think you now have enough information to make your own informed decision, and I wish you luck.
