We got the oil pan, intake manifold, and a few miscellaneous items back on the E30 stroker a few nights back, but we found a fuel leak at the injectors while priming the system, so we decided to call it a night.

Today, I brought over some 'i' injectors, new injector o-rings, and a late model fuel rail which works better with the late model injector harness. Priming showed no leaks.
We nervously cranked it and had a partial success. The engine would start and die soon after, or would bounce off the rev limiter with partial throttle, so we made a list of things to test over lunch and got to work soon after.
After reasoning that fuel and spark were probably ok, we diagnosed and replaced a bad airflow meter and plugged a vacuum leak from an unused port on the throttle body (also on the to-do list, which we hadn't checked in our excitement). Another crank and it fired right up!

We were running the car with open exhaust ports, which is deafeningly loud, but also amazing in the dark since the motor is shooting blue flames right out of the head.
It also helped us see that #2 was running a little weak, so there was more to it than just the coolness factor. A video does exist and I'll post it if Leo gets around to uploading it.
