May 2013

ACR has been at its current premises since its start 1996, and has grown considerably over that time. We have used all the space available here at J Reid Trading and are bursting at the seams! ACR now have aquired land and buildings on Factory Road formerly belonging to Veolia PLC.

ACR Jaguar V8 sports engine News 

Now in its third full season of competition, Dan lofthouse continues to test in action the latest tweeks with ACR 4.4 Land Rover / Jaguar V8 engine. This highly competitive budget clubman racing engine has simply blown away the competition running engines costing 3 or 4 times as much. Totally reliable and trouble free, the engine now exceeds 380 BHP and 350 FTLB of torque on a carefully built but basically stock engine. This year, we have further pushed the performance with a new set of super high lift cams, which required machining the cylinder heads for clearance of the lobes. Dan will no doubt endeavour to find the limit of the excellent Jaguar V8 engine again this season!

The key to much of this engines exceptional torque and power is from the level of control afforded by the Pectel SQ6 ECU. Even with super high lift cams, we still retain the Variable Valve Control (VVC), and the Fly By Wire ( FBW ) throttles enable us to run the sequential 6 speed gearbox without the clutch. We really can get the very best out of the engine at every load and RPM. Even further improvements are in testing, ever mindful keeping costs low.

Ever popular are the older first generation Jaguar engines. ACR offers the Omex 710 ECU package to run these engines standalone for the 3.2, 4.0 and 4.0 supercharged engines. We look forward to seeing Richard Green, and Steve Smith this season, with Steve running our first Mercedes 5 speed 722.6 Jaguar gearbox control system. Later 3.6 / 4.2 / 4.4 engines with VVC and FBW are better run with the Pectel SQ6.

Nissan 350 Z News 

ACR Offer the Omex 710 to run the stock Nissan engine standalone. Engine runs completely standard crank and cam triggers, and all the stock sensors. Even standard exhaust manifolds! A mechanical throttle body is fitted in place of the electronic unit. Full variable cam timing, which this engine depends on heavily is fully operational. 290 BHP from a very light, strong and compact engine. 

Engine test and set up. 

ACR enjoy an excellent track record of supplying and setting up standalone engine management systems on its in house dynamometer, for all kinds of purposes. Racing, IVA emissions complient road vehicles, generators and pumps. We have setups to quickly turnaround the popular Rover V8, Jaguar V8, Jaguar V6, Nissan 350Z,  BMW M3 / M5 6 cylinder, Land Rover 4 cylinder petrol and diesel, Land Rover TDV6 engines, and can set up for other engines of similar types. We prefer Pectel and Omex where possible, as we have grown to love the functionality and reliablity of these systems. However we will work with DTA, Emerald, Motec, MBE, Simtek / Specialist Components and other systems as our customers prefer.

April 2012

Automotive Component Remanufacturing Ltd acquires Wildcat Engineering.

Wildcat Engineering, the specialist engine component manufacturer and  Rover V8 race engine builder has been acquired by ACR following the  decision of Wildcat Engineering's owner Ian Richardson to retire.

Wildcat Engineering's products include high performance cylinder heads  manufactured from completely new castings, throttle body intake manifolds, dry sump systems, front covers and associated high performance Rover V8 engine components.

Ian remains on hand to assist with the transfer of tooling, foundry  pattern equipment and product expertise.

ACR Engineering director Roland Marlow reports "We have been involved  with the Wildcat project for a number of years, having built and dyno  tested Wildcat engines for off road motorsport, and are very familiar with the product. We are delighted to take on Ian's business, and will ensure the huge experience and effort gone into the Wildcat component 
development so far will be maintained and expanded. It fits right in with our existing business, and complements our existing Rover V8  range of sports and hi torque engines."

Over the next few months, ACR will be setting up the Wildcat tooling to suit their CNC machine shop with the objective of maintaining stock availability of the Wildcat product range.

Website will be updated as information  and stock becomes available.

Second place overall on first competitive outing

The ACR 4.4 Jaguar sports engine powered Lofthouse Freelander is showing its pace with two amazing second overall podium finishes in its first two competitive outings.
First event was the All Wheel Drive Clubs and Northern Offroad Clubs interclub Wisbach Safari.
Second event was the British Cross Country Championship ( BCCC ) Cardiff Round.

After the Cardiff round, on the Brynffynon hillside course, driver Dan Lofthouse reported to BCCC news " I am pleased to be second. We are still at the early development stage with the car, and I didn't expect we would be doing so well so soon". He added " There is a lot more to come from the car, and we will be upgrading it through the year".

The full race report and news and further information about the BCCC can be found here ( You can find more information about the car and what's inside it here (What's inside the Lofthouse Freelander?).

Back in the workshop, ACR have been busy with an exciting new development for series and early 90 / 110 owners with the 2.25 engine.
ACR are dedicated to keeping the series land Rovers on the road with our range of remanufactured engines and the Power Plus range of components.
