Check wastegate(round valve on turbo)is working it may be loosing vacuum,or you have an electrical issue with the boost controler,but check wastegate first as its easier and could be the problem

It sounds like a lack of fuel to the injectors. check the fuel manifold pressure and the regulator. run fault codes to check for faulty sensors.

Oil getting too hot

I guess my first question is - how do you know the oil is too hot ?
Engine oil is designed to handle several hundred degrees of heat, so unless the engine coolant is over 275 degrees the oil should be functioning correctly.
If you have worn bearings you can loose oil pressure as the oil heats up because the oil gets thinner. And if the oil pressure drops below 5psi you could loose power to the fuel pump.

I have a 1990 Legacy 5 spd. One of the sparkplug caps. keeps popping off causing the motor to lose its cycle. What is causing this?

Is this one of those plug boots that also seals the hole in the cylinder head around it? The plug might be loose,or missing a gasket(if it is supposed to have one).This would allow cylinder pressure to blow the boot off. Or,maybe the plug's porcelain insulator is allowing cylinder pressure to blow inside the boot.

Losing boost!! I have a 1993 mazda rx7 13b twin turbo with the stock turbos. When i punch it my boost goes up to about 10psi. But bleeds off and i can head it blowing out. Was thinking it was blow off...

Have you checked all the tubing cuplings? When mine was doing that i had a cupling that would keep sliding off just enuff that it was letting out air and loosing me boost.

Hi i have a 1990 subaru legacy rs BC5 single turbo it seems to blow turbos all the time, the blow off valve opens up on idle even through the boost gauge reads zero and when it drives and hits boost it...

Hello, that is a puzzler, but the blow off valve opening up at an idle is making me think exhaust/catalytic converter restriction causing to much back pressure. Like it can't get the air through fast enough so it's backing up in the intake. I would start my chase there... Let me know if you find any thing...(subyguru)...
