Conversion Flange for Radix J-Tube/90mm LS2 Throttle Body ....PICS inside!!
#94
Here are some prototype photo's of my Radix J-Tube Conversion via Richard @ WCCH. He has managed to help us out during a very busy time of the year, "Racing Season", when everybody needs their stuff done yesterday
This is prettymuch what the production run will look like. There are a few tweaks here and there that will further revise the flange/J-tube before they are released. On the units Richard modifies himself the inner weld bead will recieve a hand blending and your J-Tube will recieve a machining procedure to further enhance accuracy of fitment.
The flange started life as an 1 1/2" block of aluminum, which is exactly how much is machined off the J-tube for prep. The face of the conversion flange is indexed to the stock mounting position while the body of the conversion flange is slightly canted(or angled) so that it mimicks the original flow path of the J-Tube inlet area and so that the surface mounting area of the 90mm TB is oriented just like the stock flange. This will greatly minimize any fitment issues using the "Radix kit" supplied inlet tube. The tabs you see on the back of the conversion flange are there to properly position the conversion flange on the J-Tube so that the welding procedure is as accurate and precise as possible. As long as there is not excessive core shift with these castings we will see little in the way of issues. Whatever differences may arrise, the bellows of the radix inlet tube/MAF area will compensate for any minor variation. Other nice features are the perimeter of the conversion flange will follow the lines of the LS2 vette 90mm TB leaving the appearance looking clean and sanitary, and the factory O-ring groove will make replacement a breeze.
Now that all the fixtures are built and programs made, if/when you send Richard your J-Tube for modding the turn-around time should be fairly quick which equals very little down time for us. The details of conducting a J-Tube exchange program are being worked out and will take a little more time. Enjoy the pics
"This is my J-tube, there will be many like it, but this one is mine"







On a personal note: I'd like to thank Richard for all his hardwork, R&D, time and advice and BlownChevy for always helping a bro out when no one else could or would

one more thing, I am sure I read on this post that the "J" tube only had 5 bolts in the back. The picture shown has 6. Did you just take off the J tube on yours (moregrip) or did you take off the hole Radix

Never mind, I just looked and someone said there is no bolt in the lower right
Also where do you pick up the Gasket Eliminator 510? Is it at any parts place?
Do you put on just a bead or do you smear it on?
I am really getting excited about this Mod
