Finished modifying my TPIS modified 90mm LS6 intake, pics inside. I ordered a TPIS 90MM LS6 intake a month or so ago, and received it in the mail. I wanted to install it with my billet fuel rails, Katech valve covers, relocate my coils, etc. I looked at it and thought "Man, that is an ugly looking intake!" And it was, it was a factory LS6 intake that had been ported and had a 90MM snout glued to the front of it. So I started sanding down all the factory casting marks on the top. I got it nice and smooth, and thought "It's still ugly!" and kept working. There were 4 tabs on the side of the intake, and since I am relocating my EVAP, most of my wiring harness, the coils, and ditching my fuel rail covers, I decided this wouldn't work for me. So I used my dremel and cut the 4 tabs off. Well, under the tabs were low spots for clips to snap in, and my intake was now uglier than before. So I ground all the edges down, and busted out the JB weld and liberally applied it to the intake on all the spots I had cut.
I would apply it liberally to the low spots, let it dry for a few days, and then sand/file the crap out of it. I kept doing this until the surfaces matched and were perfectly smooth. Then, I kept sanding the intake some more. I also worked on the snout, using JB weld to blend in the areas where the glue was very visible, then sanding it down. I also removed the marks made from cutting the original snout off, along with blending the casting lines on the front.
When I was done sanding the intake, I sprayed it with a few coats of sandable primer, and sanded some more. My goal was to make the intake as clean as possible, but still look like a stock piece so I sprayed in such a way that I would have a light texture to it. I know, it doesn't make sense that I spent so much time sanding it, but this way I could make it how I wanted. I then used several coats of a semi gloss black, and here it is. I just washed it in these pics, I plan to put it on tomorrow and don't want any dust from sanding inside the intake so I rinsed it with soap and warm water very carefully. Here are some pics of the finished product. Some of the spots look kinda funky in the pics, but they are all smooth. This intake is wet, and the pics were taken with a cell phone!
I'll be sure to post pics of my install, I have A LOT to do. This is all going on a 382 LS6. Thanks for looking!

Out of curiosity why did you go this route instead of the FAST? I ask b/c here you pay $350 for the intake and $350 for a 90mm TB ($700) whereas you can get the FAST IM/TB for $1100 and sell your LS6 intake and TB for say $350 and you're at $750 out of pocket. I've heard the 90'd LS6 will do a little better on a mild setup than the FAST but your sig says 383 so I'm sure you've got some decent heads/cam in there.

while i agree with Red99
i can understand just wanting to do something different.
i'm VERY interested to see what the intake does when installed and tuned.
if possible, dyno before and after so we can see what the REAL gains are.

Looks awsome man, I like your style. If I ever get a fast I plan to sand the letters off and spray it texture black. Keep it looking real factory under there.
It almost looks like a street warrior!
