I was able to tighten my crank bolt. I'm trying to remember how I did it. I believe I just put it in gear. I know I did not pull the starter.

I too rear mounted my battery. I also have a saab intercooler. You will want to get a blow off valve to replace that 15psi pop off valve. I got one on ebay from an eclipse. you need one that can hold 15psi (what the pop off factory valve provides). A blow off valve will keep boost from falling too far between shifts. When you pull the pop off valve, the good news is that underneath it, there is a threaded hole in intake. I intend to just plug this with a brass plug/nut when I determine size and thread pitch. This will allow you to reverse the intake inlet where turbo pressure currently flows into the intake. Right now, that small tight 90 degree rubber elbow won't leave room for 2 hoses. But as I said, with pop off valve out of way, you can reverse the turbo inlet adapter and have plenty of room for intercooler hoses/piping.

ps, make absoluteley sure you are at TDC, cause this engine will bend valves if the camshaft is out of sync. (complete rotate engine a couple of times to catch this) I pulled the valve cover and insured both valve lash clearances on no.1 cylinder were correct when cam and injection pump pulley arrows were precisely at each other and crank at TDC.
