Custom Tubular headers with a top mounted Precision 6766 Turbo

If you want the thing to be remotely reliable - do yourself a favor and pick up a set of S6/S8/A8 NA exhast manifolds and just elbow off of that. Custom made tubular stuff tends to crack really quickly and doesn't give any real benefit.

For a journal bearing 6766, will an oil reducer be necessary?

No, if you feed with AN3 from a stock banjo. Maybe even AN4 can work as is.

I plan on having the power delivery coming on smoothly on the right end of the power curve to help prevent not throwing a rod. Feedback is greatly appreciated.

Stock rods live just fine at 25+ psi on small peaky hybrids. You'll be fine with any power delivery with a big turbo (it's naturally smoother acting), as long as it's properly tuned (and fueled!) and doesn't knock. Talking gasoline ofc.

Twin Walbro 450 Fuel Pumps

Twins = overkill, unless you go E85.

yes, the turbo will be sticking out of the hood...

I don't like this.
Comes down to personal preference ofc, and you're free to do whatever as it's your car. But to me the whole idea of such build is to have a "sleeper", that can surprise everyone with sudden 700+hp.
