Dimitar Kaleev is selling his custom 1996 Oldsmobile Cutlass Supreme. He purchased it as his first car in 1999 and then went about upgrading every major component.

After the factory engine died in 2002 Dimitar installed a 3.8 L Buick 3800 Series II L67 and 4T65-E HD four-speed automatic transmission out of a 1998 Regal GS. Then he upgraded from the factory Eaton Gen III M90 supercharger to a Magnuson MP112 supercharger.

Eventually Dimitar decided to rebuild the engine and switch to a turbocharger system. The engine was upgraded with a balanced crank, Diamond forged pistons, JE pistons, Intense Racing S3 turbo camshaft, and custom ported heads. Together with a T72 turbocharger the engine produces 600 horsepower to the wheels. Behind the engine sits a Getrag 282 five-speed manual transmission with a SPEC Stage 3 clutch and F-body 3800 flywheel.

The car rides on A1 coilovers with KYB GR2 struts. It stops thanks to Corvette C6 Z06 six-piston with 14″ rotors up front and GEN3 W-body rear brakes.

    The ” currently for sale” link is not working!!!
    This is something which my feeble mind could have never conceived. If someone had just mentioned it to me I would have completely blown it off as a 1996 Olds that needs help getting out of it’s own way. But, BUT seeing this and all the parts come together, I’m thinking WOW. Get that link fixed quick…
