4.0l Standard GEMS RPi Rover V8 (built to order)

Out of stock

Product information

For sale here we have an RPi fully rebuilt 4.0 liter turnkey engine in standard fettle. 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 or Defenders to 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 rigorous testing and build standards meaning you can be sure of the best quality and excellent longevity regardless of the application (with a few obvious exceptions). 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.
