Brief History

ACE Performance Engines (Formerly Aircooled Engineering in the UK 2010-2019) was founded by Hot Rod & Aircooled VW enthusiast Stefan Rossi in 2010. Stefan specializes in GM LS small block series engines and Aircooled VW engines.

Prior to opening the ACE doors for business back in 2010, Stefan had worked for some of the top VW restoration and engine shops in the UK & Canada, he also served in Afghanistan with the British Army. After 9 successful years based in the West Midlands, he felt it was time to expand the business across the pond.

The new shop is based in Torrance, California and will continue to specialize in new performance engine builds for Aircooled VW, Porsche and Chevrolet LS based engines.

The Builds

All engines are built by one engine builder in a clean, purpose built engine room. Each engine is fully balanced, blueprinted and built to highly detailed show standards. We also have an in house machine shop and ultra sonic tank for deep cleaning of engine parts. All builds are photographed and posted on social media to allow each customer to follow their build and see exactly what parts are going into their engine! Here is a selection of pictures from previous builds, you can find plenty more on our Instagram & Facebook pages!

          

Upcoming projects…

An upcoming focus for 2019 is to provide a complete Aircooled VW turbo kit. This will be available to purchase with an ACE engine or separately for your own engine. The kit will consist of the best parts currently on the market… FuelTech EFI, A1 Muffler stainless turbo header, Garrett ball bearing turbo, CB Performance throttle bodies and finished off with Aircooled Engineering billet CNC parts.

Chevrolet LS turbo kit also coming soon… 

Keep an eye on the Facebook & Instagram pages for details!
