I have a client who works at a Jaguar/Landrover dealership. He has a Jaguar F type and I won't tell you how little he pays for it. He was telling me the engine is a Pontiac Solstice engine with a turbo..they are both 2.0 engines but that's as far as I get trying to see if he is right. I'm not sure who built the Pontiac Solstice engine but I doubt it was Pontiac or even GM ......
