I'm thinking of going turbo on my '94 SC. It is completely stock except for a built 2003 mustang 4R70W, and mach 1 torque converter.
I can mig weld very well, and have fabricated several exhaust systems from individual mandrel bends on several different cars. I have access to a TIG welder as well for aluminum IC piping fabrication.
My plan is to start with a refreshed '91 SC shortblock (8.2:1 compression), with the '94 windage tray and oil pickup, MLS gaskets, and head studs, and the '94 SC cam as I feel it is better than the early model cams IN A TURBO application.
The turbo I am looking at running is a single Borg Warner S256 w/extended tip, and using a Tial 38mm external wastegate.
The goal of this project is 350whp on a stock longblock, fast spool, and good drivability. Not looking to win any awards for "highest HP" or fastest 1/4 mile times.
Why do this? I made 345.5 rwhp and 402.8 rwtq on my old M90 setup?? Am I stupid? Well, no.. Lets add up MP blower, inlet plenum, big cam, springs, ported heads, SCP headers, pullies, big TB, big MAF, yadda yadda yadda.. Not to mention poor gas mileage to boot.
I think for much less than the cost of those things, I can make my own streetable turbo kit that will be fun to drive daily, and just as fast, if not faster.
I'm thinking of fitting FWD 3.8L (taurus, windstar, etc) center dump exhaust manifolds, bringing the downpipes forward (2 or 2.25"), and making a custom upper intake to bolt to the existing SC lower, with an adapter to utilize the factory EGR (we have smog tests here in CO)..
Also may go Precision T61 turbo, but I think the S256 will spool better and more than be able to meet my daily driver horsepower goals.
Thoughts? I'm thinking it will be a fun winter project.
With an uber quiet exhaust, i think she can be a sleeper.
