Ok, I recently acquired a 88 10th ae. w/ blown motor. I swapped in my 91 jspec(swapped the front coverer w/ a s4 motor) removed all emissions just like Kevin Landers told me to(followed your instructions exactly. I am still running the BAC valve. here is my current setup

91 jspec motor w/ 120psi compression on each rotor
60-1 HiFi hybrid turbo
s5 manifolds
s4 throttlebody(w/TB mod and s4 tps
no smog pump
no acv, egr, or rats nest, running vaccum to boost sensor, FPR, and Oil Injectors(oil injectors are connect to stock port, this was left untouched)
s5 CAS
Walbro fuel pump(getting steady fuel, good fuel pressure)
Using S4 T2 Harness w/ all S4 sensors

I have fresh gaskets on all manifolds and the throttle body, all vaccum ports that are not in use are plugged, I have good engine ground.

one of my major concerns is that I may have the cas stabed in 180 degrees. I dissassembled and reassembled the main pulley assembley, mazdatrix told me that they will only bolt up one way (asymmetrical, idiot proof) so I set it at TDC and stabbed in the cas(with the cas aligned to mark on gear)

I have swapped several N/A engines, done 1 n/a to turbo conversion, and 2 turbo motor replacements(stock stuff) , this has got me completely boggled, please help.

The engine will crank over all day, but will not fire, rotates great.

I do have 1 stray connector coming off of the charging harness, there is the lead that goes to the oil level sender, and another lead that I forgot where to connect it and cant find a stray lead similar to this(been drinkin a lot) this lead is a single red wire with a male spade type of connecter shrouded in a plastic housing that holds the locking tab for the other end of the connector. where the hell does that go??

Please help me out , i gotta get this car under its own power by tuesday.

 

Have u checked the plugs to see if ur getting fuel? Double check ur fuel line, that u haven't got them reversed. I helped a friend with his "no start" prob after he had rebuilt the engine and then put it back in the car, he had the supply and return lines reversed.
