A-SD have been building A-Series Engines for Road and Race use since the 1970’s, with machinists from the era when tuning the A-Series was for real competition use we know how to get the most out of the engines no matter what your application or needs.

Since the 70’s the most cost effective way to get power into your A-Series powered car was to start with a 1275 / 1300 power unit. This has been turned on its head in recent years, where you can now be spending anywhere upto £500 for an untested 1275 unit.

With interest from specialists and car enthusiasts, you can be sure you will be seeing the A-SD performance packs on plenty of 998 and 1098 Power Units.

Most customers will have an engine to send back to us, and where possible we encourage this as it means that we always keep a healthy stock of doner engines to
recondition. We ask that the engines are cleaned off and drained of all fluids as our courier can refuse to collect engines that are leaking fluids.

Engine Pallet Surcharge: £50.00
Our workshops have engineered metal frames that secure inside a crate to safely transport the Engines. We are keen to get these back to save our workshop having to recreate them. These are ideal for you to secure your engine to and send back, but if you do not have an engine to send back, simply send the frame back to get your surcharge payment back.
