Product information

For sale here we have the ultimate in Rover V8 engines, without question. This is an RPi fully rebuilt Rover V8, however it's no ordinary Rover engine. This is a 4.6 liter, Stage 4 "Merlin" engine with a triple throttle body set up and carbon fiber inlet plenum. Sold here as a turn key engine, this uses the GEMS/Sagem engine management system and will be supplied with everything needed to get you up and running including ECU, engine wiring harness, injection and ignition systems meaning it's ready to drop in, plumb up, plug in and turn the key.

The engine here can be configured to suit a huge range of vehicles from Range Rovers, Defenders, TVRs or kit cars; just let us know what you're building and we'll do the rest. This engine will of course also be built to our rigourous testing and build standards meaning you can be sure of the best quality and excellent longevity regardless of the application. This means you're getting a block which has been hot pressure tested across all 8 cylinders to ensure it's not cracked, and with our correct ECU chipping and ignition upgrades it's far less likely that it will ever crack.
