Product Description
Rover SD1 V8 Camshaft, Kits and Components
We stock a full range of Standard camshafts, which represent good value for money.
We also offer a choice of Kent Performance camshafts - available either as complete kits or on their own - which are designed to improve torque and horsepower when fitted to standard or uprated engines. Kent Cams are renowned for their range of performance enhancing cams, and have been manufacturing in the UK since the early '60s. No other single modification will result in a greater increase in performance, than by fitting a performance cam. Rimmer Bros stock a range of Kent hydraulic cams and also offer a selection of cam kits for the Rover V8 engine. Depending on whether you want a straightforward bolt-in cam to improve bottom end power and torque, or are looking for a competition spec set-up which involves modified heads, enhancing the bottom end, fuel and exhaust systems (and perhaps an upgraded distributor), we can help!
Essentially, there are 2 different types of cam for the V8:-
Non GEMS (to 1995), and GEMS type(1995 on, ie 4.0 & 4.6 litre Range Rover 2, 4.0 Discovery 2 & Defender 4.0 EFi). GEMS refers to the electronic engine management system, where there is a sensor pick-up on the rear of the block. GEMS engines are distributor-less and have a crank driven (as opposed to distributor driven) oil pump. This then dictates the type of cam installed.
We offer 4 different types of cam / cam kits, ranging from the Sports Torque to Competition. Our cam kits include the minimum of parts required to install the cam chosen. Our Kent cam installation kit should also be purchased separately (see item 2, RB7488KENT), along with a head gasket set (since valve springs will need to be changed)-see page 25. There are also a few other options to consider depending on your requirements, such as uprated timing chain set, or uprated head studs, main and big end stud & bolt kits. Finally, you may also wish to consider a K+N Filter or even a 4 barrel carb / re-chipped engine management, or performance enhancing extractor manifolds. (Please see relevant sections). If you have any specialised requirements such as high-end competition/racing (solid lifer) cams or cam kits, please enquire.
