Hello just wanted to post an update of where I'm at with this. Picked up some new hole saws Plotted the holes on the flanges that were previously cut and drilled them out Tacked in a length of 2" exhaust tube and bolted the turbo up. I also made a card board intercooler for plannig. here is how it looked

Wanted to get the intercooler a little more centered and did not like what I was left with for air filter placement and oil fill access so we turned it around and re clocked it
Well that seemed to open up some possibilities. so I rolled some print paper into a tube [it was only 2" not 2.5" but was able to let me imagine it better.] and this is what we came up with using this intercooler








I am really digging this lay out
!!!I will probably raise the turbo up a couple inches and tilt the intercooler to get a strait shot at the inter cooler. It will get a1.875" -2" coupler then a 2"-2.5" reducing coupler to intercooler. then a 90* coupler out to a
T. Then a Couple 90* elbows to the throttle bodies. This layout puts the air filter pretty close to where it was which I like for side mirror and rear window visibility. It also really frees up the oil fill canister that has always been a bit of a pain to get to. And this makes the exhaust pipe and muffler routing sensible and easy to build.
The plan is to build as much of the pressure plumbing out of silicone tubing using joiners at the elbows and splices as needed.
These for out of turbo 1.875" - 2" and 2" - 2.5"
And these to splice

Some 90*
Some lengths of silicone tube
They even have 4" - 2.5" for turbo inlet to air filter still have to get from 2.5" to 1.9" turbo size
Pretty simple and hopefully durable and reliable. Cant seem to locate a
T for out of the intercooler to throttle bodies. Spent more time trying to search one online than it would take to make one

I would think it would be wise to extend the T to past the turbo up pipe as I don't know if silicone would be up to the heat where they cross. Better safe than sorry I guess.
Here is a shot of where the air filter was worked real good. Thinking maybe i can put the radiater for air water intercooler up on the rack. have to find a short wide cooler/ radiator Should be protected up there and in the air. Could also put puller fans there for high load low speed situations.
You can also get an idea of how the turbo will be and see how it might be on the car. I think it will look right at home there Should be cool
Also made flanges for #1 and #3

Well that's how my plan is for now
