Why Choose an RPi Engine?

Our blocks
All of the blocks we use go through the same process to ensure they aren't cracked. First, we chemically clean the blocks to ensure that all the oil and waterways are clear. Then, the liners are removed, and the block pressure tested at beyond operating temperature. If a block fails this test, we simply don't use it, and our reliability record speaks for itself with many thousands of engines built and still running.
Our components
We use the best quality components in all our engines, using the experience we've gained over the last 30 years of Rover V8 engines. For example, we only use Piper cams, Cloyes, kent or Genuine Land Rover timing chain sets, OEM tappets and much more
Our experience
RPi have been working on Rover V8 engines and the vehicles they power for the last 30 years, and in that time Holly, our only engine builder, has built over 2000 Rover V8 engines of all specifications.

RPi Advice

  • The price shown here is for a 4.6 litre short engine with standard heads, however many more sizes, build levels and upgrade packages are available
  • For fuelling, either fuel injection or carburation can be used depending on your application and preference. Our carburettor of choice is the Weber 500 every time. If you're running fule injection, it's essential to chip your ECU to ensure correct fuelling. Please feel free to email or call us if you have any queries or would like any assistance with your decision.
  • Using the best possible ignition system is essential to get an engine running correctly, for this we always use Magnecor plug leads and where apllicable an RPi amplifier with compatible Bosch coil
  • Always use Valvoline VR1 20/50 oil in the Rover V8 engine. It's the only oil we recommend and is available from us on enquiry.
  • Choosing a long engine from us over a short engine means that tappet pre-load is already set, cam timing is already correct and the heads have been bolted down to the correct torque and sequence by our engine builder.
