The Single Turbo Caprice Classic is Alive! It was a long 10 months, but my 1981 Caprice Classic is finally 98% back together and alive!
____________________________________
A little History:
July of last year the car looked like this
Last season the car had an aluminum L33 5.3 & TH350 combo. The motor was stock as a rock as pulled with an intake and exhaust. At the time, the car had a race weight of 3620 and would run 13.0 @ 105 all day after driving to the track. It ran good, sounded cool and was an overall fun street car until I snapped n axle and tagged the quarter last May. (paint was tired anyways lol)
In August I pulled the drive-train and off the shell went for paint and body repair.

Fast Forward to today:
It was a long winter and I could go on for days about all the one-off fabrication I did on this thing. I have hundreds, maybe even thousands of hours in this car from the past 10 months getting it to what you see today.
1981 Caprice Classic
Subaru Satin White Pearl
200k mile 4.8L (bone stock internally besides cam swap and springs)
Front & Mid Plate
Comp Thumpr Cam (completely wrong for the app, but sounds nasty)
Holley Modular Midrise on 1" spacers and flipped base & 90mm Throttle
GTO Manifolds V-Banded 2.25"
2.25" Crossover T4 Flanged
Older Precision/ Garrett 70mm
Turbonetics RG45 Gate
Ford Racing 80lbers
Holley Pump, Rails and Regulator
Remote Mount Meziere Water Pump
Front & Mid Plate
4L80e Freshened with TCI Transbrake Reverse Manual Valve Body
Stock Converter and 2.93 Rear Gears (needs attention lol)
-3950 Race Weight-
I put a ton of little things into this car haha. Fender exit down-pipe where the marker lamp was, removable stock wheel on a Strange hub, 15 gallon aluminum tank in the stock location with the Holley pump submerged, bench seat mounted modified shifter for the reverse 4l80e...the list goes on and on and the end result is better than I had imagined!
Hope you all enjoy.

Damn dude I am loving this car! Sleeper to no end! Very clean. I would love to do a big body car as a nice cruiser. Any chance you may put up some more pics of the build?

Thanks for the compliments everyone.

Two weeks ago in the configuration listed above, I went to the track on a rental day to rough in the tune some more. Through the stock converter, 2.93 gears, pig rich, low timing; it trapped 117mph just walking it out. Boost peaked at 15lbs, but I was having some spool issues. So given the weight, the car was putting somewhere around 500whp down. Not too shabby for the little 4.8s first time out!
Since that trip to the track, I changed the rear gear out to 3.73 (not my first choice, but it is a heavy car with a little motor...it certainly needs the help getting motivated), I dialed in the tune-up (more timing, less fuel), turned up the boost (solid 20lbs from the top of first and on), and I went through the full rear suspension. I also corrected two small leaks I found at the V-bands which had warped.
I am still pushing it through the stock converter, but I can tell you it is a night and day difference. It feels like the way it sits it would trap somewhere in the 125-130 range. I am going to try and hit the track next Saturday.
