Rover V8 Induction

Once cylinder heads have been ported, the next point of restriction is the injection system and induction parts (Inlet manifold, Trumpet base and Plenum) and we therefore offer a porting service for these items as well. Each part is matched to the cylinder heads and the next part in the sequence in order to provide a seamless air 'corridor' from the throttle butterfly to the valve. To have your parts ported will cost just £175 per item or £450 for a complete 3-part package. Complete descriptions and pricing can be found in the products section.
