Performance Stuff for Northstars!



This page is actively under construction (Jan 2017)

We are working on some performance upgrades for the different generations of Northstar powered cars. Performance tuning is now available for 1996-1999 Northstars, and under development for 2000-2003 and 2004-2005 Northstars.

By April 1st 2016, we plan to have a performance package ready for the 1996-1999 Northstars that will bump up the output to around 375 horsepower (Dyno Proven). The package is expected to cost around $2495.

Performance Projects in Our Shop:

2004 Pontiac Bonneville GXP

     Starting with a black 2004 Pontiac Bonneville GXP and its base LD8, 275 HP 4.6L Northstar engine, this project is scheduled for an all out performance build. Once it's done and dynoed, we will have the performance package available to the public!

Eldorado One:

     Eldorado One - my first Cadillac. A 1997 Cadillac Eldorado. This WAS a base Eldorado. Not anymore!

1986 Pontiac Parisienne Brougham

     Of course.....we had to convert a small block Chevrolet car to a Northstar. We started with a FWD Northstar engine, developed custom engine mounts and headers, and installed it longitudinally into a 1986 B-Body Pontiac.
