Aircooled VW 2387cc Turbo Engine


All new 2387cc Turbo aircooled engine, using only the best parts on the market & fully blueprinted!

Each engine we build is custom per client; we do not operate an assembly line therefore our engines are not ‘off the shelf’. The list below is a non-exhaustive list of components we like to work with, though we prefer to speak to our clients first and foremost to discuss their engine requirements before finalizing the build spec.  Please contact our chief engine builder and owner Stefan, if you would like a quote or to place an order.


The perfect Aircooled VW turbo engine for street and racing applications. Our 2387cc turbo aircooled VW engine consists of the BEST parts and modern building techniques available in todays engine building world!

We use the FuelTech EFI engine management system on all our Aircooled VW engine builds. Check out the FT450 here or give us a call if you have any questions.

This engine is available in 2387cc and 2442cc sizes. Please call if you are looking to build a bigger engine. Every engine comes broken in and Dyno tuned in our state of the art dyno room!

This YouTube video shows ACE Owner and Chief engine builder, Stefan Rossi, doing a little fine tuning with a customer on the street with his 2387cc turbo engine running on E85. This motor makes 292w/hp and 344fw/hp at just 10psi of boost!

We have personally tried and tested all the parts we include in our builds, ensuring our customers get the best of the best. We blueprint every part and stage of our engine builds. Cylinder surface finish and geometry are vital steps to any engine build, not just aircooled, though they are often missed or not even considered.

Take a look at our Machine Shop page to learn about the importance of surface finish, and our Engine Room page, where we show you our top of the range measuring equipment and the clinical, clean, engine assembly room.
