1992 BUICK ROADMASTER ESTATE
SOCIALS
GOALS
-
TRANSMISSION
Long term goal is to put a 6L90E 6 speed auto in the Buick. This is going to be a challenge due to the small transmission tunnel in B-Bodies. We will likely produce a kit for this swap. A 4L80E is currently in the car for V1. V2 to come soon.
-
REAR END
We have purchased a complete rear end assembly from a 2011 Cadillac CTS-V. We are working on developing an adapter to mount the CTS-V rear end assembly into the B-Body frame.
-
WHEELS
Our 3D models have allowed us to change wheel options very easily. Ultimately, we ended up with a 5Y design that originally came on 2014 Camaro Z28 models. This design is readily available from many aftermarket wheel companies.
-
BODY MODS
Many modifications are planned for the Buick. Aftermarket fiberglass bumper, hood, and roll pan are in the works. We will be making a custom tail gate and possibly replacing the stock door handles with an option from Kendig It Design.
-
INTERIOR
The stock interior of the Roadmaster has no support for spirited driving. We will be replacing the front bench with performance style buckets and a center console while the rest of the interior is updated to match. Retaining the rear facing seat is mandatory.
SPECS
-
ENGINE
We have built a very robust 5.3L Gen-3 LS engine capable of 1500 horsepower. This engine is installed in the car in an NA configuration. We will be bumping ther power up with the help of mirrored twin turbos from Precision Turbo.
-
SUSPENSION
The entire suspension has been replaced with QA1 tubular control arms and coilovers. The drop is accentuated by Belltech drop spindles and new bushing and bearings all around.
-
BRAKES
The stock brakes on the Buick were in rough shape when we purchased the car. We replaced all of the braking components with R1 Concepts Geo-Carbon rotors, OEM calipers, pads, lines, drums, and shoes.
