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.

Our in-house team has been working behind the scenes, coming up with exciting and cost effective ways of getting genuine power and reliability for different applications from the smaller bored A-Series units. 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.

998 Stage 2 Tuned A-Series Engine

IMG_0451-e1484938029527-330x248.jpg?resi998cc Surcharge: £150.00
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.

Short stroke?


Hi, I suppose in true terms this 1047 motor is not a true short stroke as the bore diameter is not larger than the stroke, I believe the 970 (possibly 1071 as well) were the only true short stroke engines in the range. 


I will change the listing as it could be misleading. It is merely the shortest stroke in the range. 

Many thanks
