Ok, so lemme start with what I have for a car. I have a EG6 with a b18b1 turbo motor making about 400+hp with a b16 head fully built...But the exhaust wasn't hooked up right after the downpipe from the turbo. I bought it the other day down in texas and drove it back home to vermont. Approx 2300 miles, quite a haul. I got through texas in a little less than a day and breezed along through the night.

About halfway through the trip it started to misfire and backfire terribly around 6000rpm. Then it got worse througout the trip and wouldn't let me get past 4000rpm. Yeah you guys probably would have turned off the engine at that point, but I had only 700 dollars with me and we were 2000 miles away from home with no tools except simple wrenches. So we didn't have much we could do.

I was wondering if anyone could help me out so I don't go dropping all my money into buying a handful of new parts. My friends dad (mechanic) looked at the distributer and some parts were pretty loose so he did a small fix and fixed some of the wires coming from the MSD-6AL system that the guy I bought it from put in there. The car ran a little better after that, but not a whole lot, still wouldn't let me get past 6000rpm.

I'm probably going to end up buying a new distributer anyways but I'm not sure what I should get, I read up on the OBD1 B16 distributer but then I saw something about a OBD2, I'm not sure what the difference is...

SOMEBODY HELP ME I NEED THIS CAR RUNNING BY THE END OF THE WEEK FOR WORK!

Edit: If you have any other questions about the setup or questions about what else I have and will give you a better idea on what could be wrong just ask...I really need to get this fixed. It's my only ride!

Ps. And also the tachomter seemed like it was freely jumping from 3-5 or 3-4 grand every now and then but I'm not sure if that had to do with the misfire, it seemed like it was doing it even when it wasn't misfiring.
