We are currently assembling this V8 engine with larger displacement using our own crankshaft, titanium rods, cylinder liners, pistons, valve train parts and modified cylinder heads. New exhaust and turbochargers are included in this development. We have decided to make available the upgraded cylinder heads and camshafts for this engine as a stage 1 upgrade to other McLaren owners who wish to limit the upgrade to just the cylinder heads.
Wow thanks for the link and I have subscribed to the thread , the world is indeed a small place. A friend just did a video Performance Developments last week as part of his Porsche build and Jeff mentioned the Mclaren engine.
