Yes, they will bolt up... no, the internals will not hold up.

Why not drop the SC motor into your 97? A JModded 4R70W ought to be able to survive if it bolts up. I think it should, but I can be wrong on this point.

Don't waste your time

But ......if your pockets are deep

Get a new PA built tranny, 8.8 rear, new drive shaft, bigger half shaft. And most importantly, a built engine with forged internals that can handle boost.

After spending around 9k then you are ready for boost. The only question is, who makes kits for N/A Tbirds?

I wouldn't mine getting my hands on a Kenn Bell 1.7L autorotor. The supercoupe guys have found a way to mate one up to their cars, what about us?

You can use the Vortec kit from a Mustang 3.8 and it will work. Member rancherlee has this setup and can probably answer any questions when he's on.

ok ok i've got the best possible solution for you:

swap a splitport 4.2L in, save money, save gas, get good results.
or, if you're feeling cheap, simply buy a splitport 3.8L. They are common and CHEAP. (the 4.2Ls are harder to find and generally more expensive but you do get more hp)
get a 03-04 windstar intake (the 1999-2002 intakes are PLASTIC and are to be avoided at all costs), or F-150 intake. Port-match the Windstar intake.
oh, and pull the 5-speed gearbits out of the SC. (if it is a 5spd, if not, keep your 4R70W)
and pull the SC's 8.8 rear diff.
and the driveshaft.
and the halfshafts.
and the springs.
and the swaybars.
pull SC 8-way adj. power seats.
install parts in your car.


put your parts (springs, sway bars, d/s, rear diff, automatic gearbox) onto the SC.
strip sc.
race gutted SC.

have fun.

the end!

that said, SCs are such a bastard. I owned one, and while it was the fastest car I have ever owned in my life, good jesus, was it a BASTARD to work on. It died when the N/A 3.8L bottom end that was in it happened to snap the crankshaft at the #1 cylinder under boost. That was a sad day. If I had the chance, I'd do it all over again, too. But I'm happy with 4.6L now.. even though it isn't what the 3.8L was. and gets crappier mileage.

well actually a stock 3.8 can hold some boost respectably (as long as you get enough fuel in them). i think thomas had mentioned sometime that they can hold about 8lbs. roughly.

Hopefully you are not talking about a v8 engine swap.

Actually, from what I read, you can get SC like numbers by just doing a splitport swap to your N/A motor. From there you can put in a cam during the swap and a SCT chip for more go. If you watch what intake you put on, you can go back with a Vortech or a turbo for even more insanity.

A split port swap will not get SC hp numbers. The 89-93 SC was rated at 215 hp while the 94-95 were at 230 hp.

A split port Mustang was rated at 190-200 hp.

Cammed and chipped with a few other bolt ons has resulted in about 230-250 hp for most Mustang V6 owners.

A 94-95 SC with a 89-93 %10 overdrive pulley will reach that power level. Add exhaust, larger TB and MAF and cold air etc., and you will be between 280-300 hp. The major difference though will be the torque. While big hp is nice, it's big torque that rocks.

Most don't realize that torque is what gets a car to about 3/4 of the way down the quarter mile.

My mildly modded LX pulls pretty decent of the line, but my bro's heavily modded SC literally sucks you back in the seat.

you mentioned the split port mustang. is there any difference between that and the split port f-150 that people use for the split port swap?

The split port in the F150 is the 4.2. Essentially very similiar to the 3.8 but dimensionally a little larger shortblock due to a deeper oil pan.

They were also rated at 210 hp and 255 ft lbs of torque for a little more power and have an entirely different intake design.

It takes more then just those few bolt-ons to hit 280hp.

I've had a 91 SC before i got my 95 V8 and I liked my SC better. You'll get into a lot of work making power out of the early 4.6 motors. I'm in the process of swaping in the Mark VIII motor. The SC motor is definatly worth it. If you can, get ahold of a 95 SC motor. The 95 is the last year of the SC and is the only year of the power increase due to the supercharger internal ports being slightly larger. If you have the time go to the Ky chapter and talk to a guy nammed Jeff Bratton. He has a nice SC ang can tell you all about them. Later.

I've only driven one SC and one 4.6 Bird. I much preferred the power of the SC to that of the 4.6. But I like the Mark VIII's 4.6 more than an SC. Enough low-end to make it fun, but plenty of top end and much more refined-feeling than the 3.8.

The Mark V III has the DOHC 4.6, the TBirds did not.

That's what I was saying, I like the DOHC 4.6 better than the SC 3.8, but the SC 3.8 more than the SOHC 4.6 (in basically stock form.)
