    M30b35 engine specs

    Does anyone have or does anyone know where I can get full engine specifications for the m30b35. I am talking about, bore, stroke, deck height, combustion chamber volume, rod length, head gasket width. And specs for the head as well like, cam duration, Lobe Separation Angle, lift, Intake closing angle, Intake centerline, etc.

    The reason for asking is I am planning on building a nicely set up N/A engine and I need to find out the dynamic compression ration so I can decide on what new static compression ration to run so I can adjust the cam accordingly.

    Thanks

        Good luck on your build. I am finishing up my N/A build now, one thing I will tell you is that it isnt cheap but I am sure you know that. I should hopefully have my dyno numbers end of next or the following week and I will post them up.

                  holy crap, now that is a built engine. Whos cam are you running, schrick? How much did you pay for the 10.5 pistons and who are they from? The best I can find are the CP ones on VAC motorsports. Also do you know the intake closing angle of the stock b35 cam?

                  Sorry that is a lot of questions but I am trying to gather information. And yes, please keep us updated on the dyno tuning.

                    I am using a reground cam from ireland engineering (going to see how it holds up), got the pistons from Import Performance Parts (http://www.importperformanceparts.net) and I think they were around $700, and I don't know what the closing angle is on the intake

                              please post up dyno numbers when you have them. that sounds like a bad boy!
