Thinking of getting a 3.8 for better mpg going to school soon and need better mpg.

What years would a super coupe supercharger work for?

How much poewr would it give me?

Is it hard to do? and how much boost can it put out?

Thanks

The gas mileage on the 3.8 is a hair better than a 4.6. Don't get a v6 for gas mileage, get it for lower insurance.
The supercoupe swap will work on 94-98 3.8's. I think the gains will put you a little above a stock split port 3.8. Those sn-95 motors are turds[:'(].

i think the 90 super coupe had 210 hp so. it wount work on a 99 and above?

Nope, not if we are talking about the same supercoupe swap here. sn-95's have single port intakes, new edge's have a split port intake.

It depends on how you drive it because I get 18+ city and 29+ hwy (04, 3.9 5spd.).

The supercoupe swap will only work on 94-98 stangs cause there singleport 3.8's I would get a 96-98 that way you wont have to worry about the head gasket problems with the 94-95's and with a supercoupe supercharger you should be putting decent hp like 220 or so but you will gain in the tq department ive heard people pushing almost 300rwtq with this setup.

The motor is the same as yours.

The M-90 will make a nice addition but you really need to up the boost to 9 PSI, or even 11 to get any serrious gains out of it on an otherwise stock single port engine. Best thing to do would be to get the following:
M-90 SC from a supercoupe, most complete kit you can find
36lb fuel injectors
155lb hr fuel pump
80 or 90mm MAF set to the injectors
9 psi or 11 psi pulley
Get dual exhaust on the car to get rid of some unwanted back pressure after the mod

Then do the following:
make the necessary modifications to the fuel system so that the M-90 fits
port/polish the lower intake and the M-90 for better/cleaner air flow

Now depending on what boost you run you'll sit anywhere from 180rwhp-mid 200s and unless you're constantly romping on the S/C you'll get nearly stock MPG.

300 rwtq damn. 220 to the wheels?

And with a super coupe can you hear it whine?
