so I'm getting my ignition signal from the crank and that's how we set it up in the beginning. we use a piston stop marked top dead center on my reluctor ring 1/8 in in front of where the sensor is and that Mark is gone. That was before I drove it from New Mexico to New England. I've never had a problem with the car. I will say this I've had many turbo engines but they've all been hydraulic heads. I've done a valve adjustment on it and it seems to run fine... may e the valve adjustment could be causing these issues if it was adjusted too tight. My last engine I put over 50,000 miles on making over 350hp with no keyway in the crank with no issues banging it off rev limiter road racing time attack all kinds of things so I don't think that's an issue. I really think it's a cam timing issue from the engine running backwards for a couple seconds or the valve adjustment is too tight. That's the only thing I can think of. I really thought this engine would be more rev happy than the hydraulic head. Here in the next day or so when I get a chance I'll do another valve adjustment just to check it. unfortunately I'm working in a parking lot while traveling and can't work on it in a garage.
