I am changing my engine and trying to get the ring that goes in the end of the crank off the old engine to put that on the new engine (new engine is a manual) And I cant figure how to get that ring out of the old one. Anyone have any tricks to remove it? Thanks!! My new engine is almost ready to go in the car just need this removed from old one to get to the new engine before i can put it together!

Do these work for our cars or overall?  

I'm wondering if the stock temperature gauge can be hooked up to the GM coolant temp sensor for use with megasquirt? How can I find out if the two temp senders have similar ranges? Does anyone have info on what the stock temp sender's resistance range is?

Started to happen a week ago, when accelerating moderately, I get an ever so light missfire at 3.5k.   Spark plugs and wires are less than a year old with maybe 4k miles on both. Boost is turned up to around 14, this occurs at .5 cmHg.   What could the cause of this be, what should I look into?
