Just got an 86 TC for 150 bucks from a friend, dis wasn't turning so he thought it was aux shaft naturally. I got it home (had already got a timing belt to do while i was in the cover) found out the timing belt was toast, lined everything up, threw it on, but the hang up is the dis had been removed when i got it and i couldn't find a definitive guide on how to stab it, so i stabbed it with the rotor at the #1 post, crank at tdc. Didn't want to even try so i retarded it, nothin, flippped it 180, nothin, advanced it, nothin, flipped it back, etc. Anyway i got it to where it'll pop some times when i stop cranking but that's it. Good spark off coil and plugs. 
My Del Sol did this and the plug wires ended up being in the wrong order, double and triple checked and I'm pretty sure they're correct. Already reset the rotor to No.1 with the crank at tdc again one time, that's when i started getting pops. Some reading suggests my cam could be one rotation off?

Did you disconnect the SPOUT connector? Underneath the distributor—running from the ignition module—are two wire leads connected to a sort of plug. This is the SPOUT connector (which I believe stands for SPark OUT, but maybe not).

This is basically a shorting plug that allows the engine to automatically advance the spark upon acceleration, etc. When it’s not connected (the plug is pulled out from the connector) the engine returns to base timing, which is what you MUST have to properly set the timing.

Afterwards you reconnect the SPOUT connector for proper engine operation.

Without the SPOUT the engine should still start and run, but not as well as it should. Trying to set the timing without it disconnected would be an exercise in foolishness.

The little round guy that just runs in a loop? Nope absolutely not lmao, thank you, I'll give that a shot. Glad i came here, it's all the little particulars like that I don't know, and are hard to find for this car. 
I know Hondas like the back of my hand, but this is new ground.

Figured it out, we didn't quite install the tensioner right and it jumped a few teeth, got it all realigned and restabbed and it runs pretty good now!
I think it's still a wee bit retarded and there's a very infrequent miss but progress feels good.

Good to hear it is running pretty good!

Turbo Coupe engines are known to “hiccup” from time to time; it sounds like it’s going to die (stall) for a second or so whilst at idle, then recovers. It’s VERY infrequent—once or twice a week in normal driving, maybe.

Mine has always done that, and I long ago gave up trying to figure out why (after throwing a lot of parts at it).

yep. if you let the car run while you're standing outside of the car, you'll definitely notice if after a while.

I eliminated 99% of the idle "hichup" issue by running a 10 ga wire directly from PCM ground pins 40 and 60 to the battery negative terminal (basically overlaying the stock ground circuit that has several connectors along its route from the PCM to the battery negative) and also powering the injectors directly from the battery positive terminal via a 40 Amp relay triggered by the VPWR circuit.

Bunch of cool info, thanks guys. Got a timing light in and actually verified and I'm at 12 degrees at idle which I'm perfectly happy with for kind of throwing it all together. It revs smooth, starts to run on 3 cyl. at 10 psi, plug wire is pretty janky, my guess is weak contact is letting spark blow out under heavier boost. If I back off the throttle it cleans back up some. Ordered plugs, wires, motorcraft cap and coil, and go from there. Really though my "hiccup" is 1 in maybe 10 k revolutions, and is just a little "buh" sound; I can totally live with that. It really runs pretty good, better than I expected. Oil pressure seems a little low at idle admittedly, probably a quarter way up the gauge, but i've driven my turbo integra a good 200 miles so far after finding a loaaad of bearing material in the pan (cleaned it out ofc) and have yet to hear a sound, doing highway pulls at 10psi tuning, the works.

Jeff I super appreciate that little tip about improving the grounds, I just might do that. Those pins are correct for my 86? Still not too familiar with Ford's updates in Fox ECU's.
Sorry for the delayed response as well, have been working on aforementioned Integra, working out kinks, waiting for the motor to knock so I can swap the fresh b20 in.

Also, from what I gather, it's pretty easy to pick up power on these things right? Headstuds, MLS gasket, bigger injectors, FMIC, more boost?
I'm used to Hondas, where you really have to tune and do support mods for any little thing you do, and I have no problem doing things right.
I guess just correct me if I'm wrong but factory hardware is pretty much good up to like 250whp yeah? I mean clutch and rear end aside.
To my understanding the factory turbo maxes at probably about that, maybe a smidge more?
