3800 Series 2 L67 Engines
IWe specialize in Series 2 3800 L67 Supercharged engines, stock or modified.  The engine became a serious interest to us about 5 years ago and since then numerous engine swaps with the L67 engine have been performed with great results.  These engines create a great balance of Horsepower, Torque, Great gas mileage and Drivability and take very well to modifications either mild or wild while retaining excellent reliability.
88-96 W-body 3800 Engine swaps
Our main swap platform, the 88-96 Pontiac Grand Prix.  These are great swap canditates and make a great sleeper car that nobody suspects.  I have swapped quite a few of these cars to accomodate an L67 and respective components and it makes for a very reliable and clean setup.  The older Grand Prix shares a few things with the 97 and up body style which keeps this a very straight forward process with a near factory look finish.  While the Grand Prix is the main focus, other Pre-Gen cars such as the Oldsmobile Cutlass Supreme, Buick Regal, and Chevrolet Monte Carlo share the same basic platform which also works great for this swap.

Prices for these swaps start at $1900 plus all required parts and engine/transmission.  This price includes complete swap labor, custom wiring, custom PCM tuning, fuel pump install
97 to 03 Supercharged 3800 Engine Swaps 
Here is a very popular swap that the newer generation of non-supercharged 3800 powered FWD cars have been going to.  There are a few ways to go about doing this. Option #1 you can leave your existing bottom end in the car and have an L67 Top-End swap done which gives you a little more compression but leaves you with a weaker piston.  Option #2 a complete L67 supercharged engine can be used to replace the existing Non-supercharged engine, be it a 3100 or 3800 engine.   For the best all around reliability and longevity a complete supercharged engine swap is the way to go.

Prices for these swaps start at $700 plus any and all required parts and custom tuning.
Custom GM Rear Wheel Drive 3800 S2 Engine swaps
The photo shows an L67 engine in the engine bay of my 86 Olds Custlass Supreme.  This project took a long time and a required quite a bit of fabrication but was well worth the effort and long wait.  The sky is the limit on a serious project like this and there are a LOT of options that can be had.  There is a lot of work and time involved in a swap like this and a lot of special parts that must be changed or upgraded to accomodate a fuel injected engine.  This makes for a rather expensive engine swap but the benifits are well worth it to the 3800 enthusiast that is looking for great economy and reliability and added power either supercharged or non-supercharged can supply.  There is a lot of options to choose from and again the sky is the limit on what can be done.

Custom G-body rwd engine swaps start at $2500 plus all parts, engine, transmission, fuel system, exhaust, and any other misc items as needed.
