Thanks Damien and Gregg!

This project sounds simple, but everything I did was hours of work. I'm very happy and proud of the outcome. I hope all the information I provided helps any other enthusiasts considering a similar swap. I know I'm far from the first to do this swap and I know a couple of the things I noted I was not the first to do, but I do believe there are a couple of porting mods and the PCV mod that I am the first to try out.

I just noticed I forgot ONE more change I made to the UIM (I'm going to add this pic to the info earlier in this thread).

You can see the tip of a screw driver at a step in the UIM. I tappered this down a lot so it's a smooth transition (I tried to carry it as far as I could to the inside of the snout).

Looks damn good!!

Now we just need to work on hiding some of those excess wires if it's possible

Also, You need to remove those mounts and paint them black. Next to the painted valve cover and UIM the brackets just look bad

Thanks guys. I'm thrilled with how this project turned out so far. I've got a LOT of hours into it. When I began, it looked like it was going to be so quick and easy lol.

Hopefully this helps anyone looking to do this mod

Looks like you did an Awesome job with it Jason Very nice finish as well, I gave up quick after trying to polish mine haha
The way I ran the PVC lines on mine is still holding up great, yours looks a little cleaner where it's tapped into the UIM itself rather than extending the lines like I did LOL
You should consider painting those mounts like Mike previously mentioned
Oh and about the MPG's I didn't really notice a difference if any after the swap, but I wouldn't say it hurt my gas mileage at all... Then again I've never really calculated what I get to the gallon. Driving down the freeway at 70 mph gives me around 26-27 mpg going what the info center in the car gives me

Thanks frank
As for the mounts, all in due time lol
So far I am thrilled how this came together and how clean It looks.
Frank you helped in noticing the first l26 uim I had differed from yours as well as seeing how you made it all work.
The wizaird was a pain to get things together, but it came together
It also helped reading stuff from some Bonneville forums.

I'm glad I was able to help a little lol
You guys helped out a lot too so don't forget that
Haha and don't even mention the Wizaired! I hate removing and installing the damn thing! I replaced the original duct with the rubber one zzp has It's a little easier to handle and get around the TB.
Our sig pics look pretty similar now haha
