Overkill has discontinued products and tuning services for the 3800 platforms to focus on new projects. After ownership of 5 W-Body Grand Prixs and Regals, the 3800 will always been affectionally remembered for what it brought me personally and professionally. Thank you to everyone for 17+ years of interest in Overkill 3800 offerings.

As a gift to the community, I'll share information on the fuel injector upgrade sold by Overkill. These injectors come from a 2006-09 Cadillac STS-V or XLR-V with the 4.4 Supercharged Northstar V8. They are rated in that application as being around 50# flow rate. They are a direct replacement in 2004-07 Series 3 3800s and can be used in Series 2 3800s with an electrical adapter. They are made by Bosch and feature a projected tip which results in an excellent spray pattern of fuel. Best of all, you can get these from Rock Auto under the GM/Delco part number 2173076 for around $30 an injector, a great deal!

Please credit Overkill for this discovery when sharing, it would be appreciated. Happy modding!
