I wonder if there are any D-series Gurus on this forum. I've been doing alil research and I want to find out if anyone has openedup the bore of of a d-series motor. I have read that the stock bore is 77mm then other places read it is 75mm. I want to find out what the biggest bore anyone has used on a d-series. I want to take a stock d-series motor and try and pull out 200whp n/a out of it. Sounds like a hard tast but I personally think its possible with the vtec models. Anyone care to shead some light on the topic?
