Need to know if i can just flip the headers up or foward and make flanges for the turbos off the stock manifolds (1994 3.0). Thinking two cheap junkyard turbos with internal wastegates mounted high enough to drain into the valve covers. Another question, if i set both turbos to 5 psi is it going to go up to 10 psi or even out to 5psi with the internal wastegates. In my head since theres no wastegate on the charge pipe its going to go up to 10 which i don't want.

Will the maf hold up to 5 psi without breaking? Also will the stock injectors keep up with 5psi. I have alot of what i need to get this done. Wondering if a fmu is a good idea or if the stock injectors and maf sensor can keep up with it themselfs

But my idea with the twin turbos is for two reasons:
1. I feel the vw/Audi turbo's exhaust side is way to tiny to push 6 cylinders through. Ive got one from the junkyard and its really tiny.
2. Exhaust seems like it would be way simpler, no crossover pipe between the manifolds and with two turbos you can run the exhaust back into the stock y pipe keeping the oxygen sensors where they were before.

My credo
Make it fast, Make it loud.
I don't know if the headers can be flipped, but if the internal wastegates have a 5# springs in them, the truck will only make 5 pounds of boost. The charge pipe only releases boost when it spikes the vacuum because the throttle plate closed (needs to be recirculated or your maf will spike and run rich as hell for a second) I personally believe the stock injectors and and mass air will keep up decently, but to make a noticeable amount of power, larger injectors and a tune would be needed. The tiny vw turbos would, in my mind, create immense back pressure.

Another question, how would the stock fuel pressure regulator react to boost? Would it mess it up? I know the brake booster has some type of valve on it that will keep it safe.

I was also at the junkyard the other day and was looking at 3.0 Taurus's. Their manifolds look perfect for making turbo manifolds

Yes, its got a newer 3.0 in it now, i believe its from a 2002. Ive removed the coolant overflow and windsheild washer tank to make room. May be pulling all of the a/c parts and even the blower motor since it doesnt work

Anybody know what i can use for an oil feed? I was going to use the oil pressure sending unit but its m14-1.5 and would need to go down to -4an line and its impossible to find a tee block for it

The sensor thread size is 1/4 npt. Summit has a bunch of fittings that will work, for it. Home depot has a tee for the size and you need a double sided nipple to thread into the block. Ill be doing a build thread on this
