Is there any way to make the auto numbers closer to that of the 5-speed??? Also curious if you had torque ratings as well???

Yep, do a T5 swap and replace the LB series computer with an LA series. Probabaly want to swap rearends while your at it. 5-speeds had 3.55:1 as opposed to auto's which had 3.73:1. The auto motors were the exact same motor as 5-speed motors. I'm fairly sure they were both large VAM and 35# injectors. I believe the detuning was done in the computer.

1987 had arrived and development of the Thunderbird SuperCoupe, a successor to our TurboCoupes, was not complete. Ford decided to insert the 1987-1988 redesigned Thunderbird TurboCoupe into their lineup as a spacer, to allow for finished production of the SuperCoupe for model year 1989. This new Thunderbird combined a new front valence and rear-end with a few more tricks under hood to produce the ultimate stock TurboCoupe. The addition of intercooling significantly increased power output. The addition of rear disc brakes increased braking ability. Hood vents and a sloped front end gave this Thunderbird a bird-like appearance, in addition to plenty of power to play.

Well, i'm happy as I found out my donor is actually a 5-speed

Any idea if there's any hp gains in using a 'proper' front-mounted intercooler instead of the one that goes under the hood???

An I/C performs much better out front in the airstream than it does perched on top of the turbocharger. Any cold air it produces is pretty much negated by the extreme heat generated by the turbo sitting 3" below it! A quick, cheap performance gain can be had by simply removing the I/C from atop the turbo, mounting it in front of the radiator and fabbing up some I/C piping. TC I/C's are small but they're actually very efficient!
