My buddy has a spare stock P28, from his Del Sol. We switched it for a Chromed P28, with a proper map. But his H22 started and drove around just fine on it, (I wouldn't recommend too much high rpm stuff) But it would crank and start a B16/B18 engine just the same.
I can ask him to borrow it for a bit? He lurks on here, he might read this anyways.
