Hi sorry I should have said. I am planning on adding a turbo to the mix down the line but not imminently. I work at a company which is pretty synonymous with engineers doing mad things to their cars in their spare time and many of my colleagues seem eager to help me plumb the turbo and increase room so-to-speak. 270hp was just a figure I wanted as I believe the BMW 535d I’m trying to whoop has about that much weighing a lot more! I’ve seen some make zetecs make 300+ with a turbo. For now, I’m just trying to throw a simple old silver top into the car, the power comes later! Hope this helps!
