Cayman The Destroyer!
Changing the stroke on a turbo engine plays havoc with the DME programming. I was aware of this going in to the project but it is more complex that I first thought. tuning found 100hp vs the 3.4L programming.My engine retains the 78 mm stroke and the pistons are 99.5 mm. I chose not to stroke the engine at all because I was not willing to take the risk of unintentional results. I think Diverdog made the wise choice by going to a 3.8 block because the block is designed for the longer strokes.
Different strokes for different folks
