I think I hurt my engine.

Okay i ripped the twins out and put my single on. Started right up. It was sitting for 4 days but that was it. Let it idle for a good 30 minutes, reved it a few times, let it idle for a bit more than shut it off. Went to start her up 2 hours later and it wouldnt start up right away. Tried 3 times and nothing. 4th time it started but sounded and acted as if it was blown. Let it idle on its on and it died. Tried to start it back up again with no luck. Felt like crying. Then i started it up again with a little gas and it sounded the same, like it was blown so i revved it out to see if it would clear up and it did. Now it's idling fine and starts right up?

1. first question...... are all the vac nipples on the lower intake manifold vaccum?? I have the OMP nipples connected to two of those nipples on the inside of the LIM. Is that okay?? What i was thinking was maybe i hooked them up wrong and they dont see the proper vaccum??

2. second question. There are two metal lines on the engine, My rats nest is gone, so the only two i have are the oil lines that are towards the front of the engine and i believe they both hookk into the Oil neck? One i believe is the Oil feed line for the turbo. The other line plugged into the turbo pipe for the primary turbo when it was sequential. I took that line and attacjed a silicone hose to it and connected it to the outter side of the LIM. Just chose the vac nipple pointing towards it.

Reason im asking this is because i think maybe i hookd those 3 up wrong?? Not 100% sure but definitely would like some feed back. I think im gonna go back to premixing. What do you guys think?? I havent premixed with my FD. Only with my T2 because i had broke the plastic lines for the OMP. But who premixes with there FD?

Thanks.......

Okay if you look at the diagram look at the light blue vac line. They connect to the omp squirters and then to the front of the primary turbo. As well as that other line i was talking about. Now you see the Bright yellow vac line that connects to the inside of the LIM, well thas where i connected the omp squirters. One to that nipple and the other to that burgandy nipple right above the bright yellow one. And the other metal oil line that is attached to the oil feed line which goes to the other nipple on the priamry turbos pipe i have that connected to the bright yellow on the outter part of the LIM. Is what i did okay or do i have to switch up these lines??

1) the oil injector feed lines can go to any filtered air source(even a single filter off of a solenoid off your rats nest will do or to your intake pipe)

2) i don't recall there being a line off the turbo oil feed tube that is used, cap it.

plenty of FD owners premix, it is a rotary thing, not a series thing.

check your coil packs, more than likely you have one that is taking a **** on you, don't ask me why mazda decided to place them there.. check your grounds and injector clips as well.

Hmmm, okay well i defintely have my Boost control Sloenoid hooked up wrong. Gotta switch that. And no i asked about the premix because i used to run it in my T2 and didnt mind throwing oil in every time i filled up. I think im gonna start again.

the boost control solenoid can be installed a variety of ways. as long as it's on the wastegate and has a pressure source, you ok. Just double check the rest.
