We are rebuilding a 1.7L which AC will be reinstalled? It is a low mileage car and the as found pistons/cylinders are well within tolerance. They really are in excellent condition. We are evaluating reinstalling after honing the walls and installing new rings. A Sanden 508 compressor will be used that supposedly has little HP drain.

Question? If we upgrade to larger cylinders/pistons what is the real HP gain for the expense? We understand drop-in 96mm walls are too thin. We also understand 94mm are a good bet but the heads have to be machined. So what is the real gain? It is that noticeable?

Thanks
Jeff
