Epoxy kinda looks like s*** but there's not much I could do about that. I sanded everything first and I also added some epoxy to the underneath side of bungs.
I would suggest trying to find a black epoxy that withstands gas. I'm actually planning to paint the epoxy black which will make it look much better.

WARNING to anyone considering this modification, you are pressurizing the intake to hopefully 25 psi while injecting fuel in to it, you get the recipe right? A leak in the intake means pressurized fuel vapor can come out of the breach and certainly could cause a fire/explosion. Also there's a remote chance if there's engine failure you could have a backfire through the intake which would certainly explode the plastic part. I think the risk is extremely low but it's still a risk. I was very careful selecting epoxy and I followed the instructions perfectly and did the best job I could. Getting the epoxy right was #1 on the list, making it look nice is second.
To mitigate risk I would assume the aux fuel system would be utilized only during WOT, or only at high boost levels. Having a fire extinguisher handy and an occasional inspections of the expoxy wouldn't be a bad idea. I'm sure if there is a leak you would hear it and smell it fairly easily.

Got the transmission and starter installed without any issues. Had a friend come by and give me a hand stabbing the transmission, that's never easy unless you have a transmission jack, which we didn't. I'm probably going to be sore tomorrow lol.

Sanded the epoxy and scuffed the plastic, then added a coat of paint. I also cut off the extra thread bar. Looks pretty good now.

Thanks boss man! I hope to have all the small details done by the end of the month. I still need to spend around $3k to get the car started (exhaust from engine to mufflers and control pack), that might take me a little while to spend that money without making my wife mad. In reality I figure I'm 60 days from having the car ready to drive.

Maybe I missed it somewhere in the rest of the posts, but what is the plan for the exhaust? Going to get custom work done or try and make something factory work?

This is a 2.25 diameter pipe, I'll be connections gt500 mid pipes from there going back to the quad tip gt500 exhaust. The gt500 mid pipes are 2.75" so there will need to be some welding to make that reduce.
My other option is to buy gt500 complete exhaust and modify it to fit the ecoboost exhaust manifolds. Does anyone have an opinion on this? Can 550-600 whp be pushed through 2.25" pipes efficiently? It's only a short distance, seems like the cats for the gt500 setups would be higher flow too since they are designed for that HP from the factory.

I've been thinking about turbo piping for months, I finally see got a few pieces put in the car and it looks like my plan will work. I strategically cut the oem pipes and added adapters to reroute the pipes in to the intercoolers. The factory turbo pipes are 2" OD (plastic pipe in the picture), I cut them and added a 2" to 2.5" 45 degree silicone fitting. This gets me a larger pipe for at least a good portion of the turbo piping.
My idea is to send the air down to a 180 degree fitting that's connected to the bottom of the intercooler. Then out of the top of the intercooler the piping will go in to the intake.
