I have a 1995 cadillac seville sls, and I want to know where I can get a turbo for this car, the design didn't change much for many years, so why can't I find one.

 

How much money are you willing to spend?

L47



[/align]A L47 inside an Aurora's engine bay[/align][/align][/align]The L47 Aurora engine was a special V8 designed for the Oldsmobile Aurora, based on the Northstar engine. It is a DOHC 4.0L (3995cc) V8 which produced 250horsepower (186kW) and 260ft·lbf (353N·m) of torque. The bore is 87mm and the stroke is 84mm. The L47 has a 10.3:1 compression ratio and uses premium fuel.
Although most of the Northstar's features, including the coolant loss system, remained intact, the decreased bore increased weight unacceptably. To reduce it, Oldsmobile used a one-piece glass-filled thermoplastic intake manifold and simplified AC Rochester sequential fuel injection. A new die-cast structural aluminum oil pan incorporated baffling to reduce oil starvation in hard driving. A starter interlock prevents the starter from engaging if the quiet L47 is already running.
A highly modified version of this engine was used by General Motors racing division initially for Indy Racing League competition starting in 1995, then was later used in the Cadillac Northstar LMP program in 2000. Both engines retained the 4.0L capacity, but the Northstar LMP version was twin-turbocharged.
The Aurora was also used in the Shelby Series 1 car.
The Aurora engine was introduced in 1994 for the 1995 model year, and General Motors has not used this engine since the demise of the marque in 2004.
