1981 Caprice Classic 4.8L Single Turbo
I have owned this car for years, and it has seen multiple combinations. It is currently under the knife AGAIN getting reworked, but I figured some of you would find last seasons combination rather entertaining!
1981 Caprice Classic
200k Mile 4.8L with Comp Thumpr (completely wrong cam for the combo, but sounded awesome!) and BTR Springs
Holley Modular Mid-Rise with Flipped Base, 1" Spacers & 90mm Throttle Body
80lb Ford Racing Injectors and 3 Bar 2004 GTO OS
4L80E Full Manual Reverse Pattern with Transbrake
Old Garrett/ Precision T4 70mm Journal Bearing & Turbonetics RG45
This combination @ 20psi on E85 was one of the funnest street cars I have ever owned.
I spent a lot of time on the details of this car. The stock steering wheel was adapted to a tubular column with Strange quick-release hub; the fender-exit exhaust came through a billet flange where the marker lamp used to be; the Holley Dominator fuel pump was submerged in the tank. Just a lot of thought and attention.
The car definitely made the rounds and turned out to be an awesome conversation piece for the shop, but as with any of these projects....It is never good enough. The motor found its way into a truck out in Worcester area, and the transmission is in a single turbo Trailblazer SS now. Once again, the car is getting completely gone through with the goal of making it even better than before.

We are actually hanging twins on the nose of the car this year with a different motor/ trans combo. Biggest goal this season is to put the car on a diet (which I have done previously, but still super overweight). Actually, the car weighed 4040 this year with me in it if you can believe that!
Once we have made a little more progress, I will start a build thread (or maybe even just keep this one updated).

Is it tub in the back? small or large tire? what rear?
Lose that front bumper and that will help...that and a tubular front end.Last edited by SMWS6TA; 02-20-2015 at 02:14 PM.

The car is not Tubbed. Small tire, stock rear rails, currently on a 8.5" 10 bolt.
Last season it was on a typical 28" radial, but that tire actually looks small on this car. I don't plan on class racing or anything like that, so I think I will stuff the 295/65 radial back on.
The front rad support and rails are getting the tubular treatment this year to shed a few lbs and hang the turbos from.

Thanks!
Thank you. The TTA was actually at a friends shop. Cotton's specializes in Turbo Buicks / Grand Nationals. They have a parking lot full of cool turbo 3.8 cars.
