Lorne-excellent link and understand that at initial startup it is critical to keep the rpms around 2000 until coolant starts flowing for proper seating of rings. I found a set of original cast iron Nissan rings for the A15 from a dealer. My goal for this motor is a long term build. The article touches on ensuring all systems are optimal so that the engine maintains the rpms, especially carburation. That leads me to the dual Hitachi's I have. Not knowing their condition, do I put the original H95 head with stock carb for the breakin period and once that is done, then remove and replace with GX head and dual Hitachi's? Those carbs may take a bit to get fine tuned and it isn't something that I should be tinkering with at startup. Not sure on the specifics of the honing that was done but know that the machinist finished with 45 degree hatch marks which were similar to the original hatch marks.
DD...My GX head has been shaved 20 thousandths over the last 40 years. It is now 28cc. A little under your range. Encouraging to hear that honing should suffice for a long time. I still haven't got around to checking ring gaps at the bottom of the stroke. Should do that in the next couple days and report out.
RT...Thanks for the offer on the flywheel, but had mine shaved down to about 15 lbs. MG weighs about 1,600 lbs which is about 500lbs lighter than the 210?? So taking some weight off was appropriate. Guys that have done these conversions recommended doing this. Not sure how your coming up with 6cc for stock A15 pistons. Mine measured 13cc. I have the offset dish type.
