Scary400, in the last picture can you see how neither the roundness of the 1uz throttle or the width of the m112 port are really used? I feel that this will greatly hinder airflow. so, I have two ideas... either modify the bracket so that the opening fits the m112 side better (easier imo) or buy a throttle body and intake manifold for a cobra and wire it in (harder of the two, and probably more expensive). The only reasons I could see going with the second option are 1 my o.c.d. and 2 the extra flow/ability to bolt on a KB big oval later on. I think for now I'm going to run it this way until the car is running, from there I will go one route or the other...

First idea I had upon seeing the image, and what I think is your idea as well, is to use a round to oval transition (see pics below). Remove the current pipe, keep the flanges (assuming the round flange matches the SC throttle body), and weld the transition to each side. These transitions are available online, but you can make your own relatively easily. One issue is that tubing large enough to be flattened into the oval shape to match the M112 inlet may be too large for the SC's throttle body. If so a reducer may need to be added to the setup as well.
In the end a Cobra supercharger elbow and an oval throttle body may be the best choice, however the solution above isn't much different short of the extra reducer to meet the SC throttle body (should it be necessary and will be removed later if you go for a larger throttle body) as even the Cobra elbow and oval throttle is going to require a transition from round to oval, just in a different spot (from intake pipe to throttle instead of from throttle to supercharger).
Do you have a workshop manual? If not let me know and I'll pm one to you. That plus the TRD Tundra supercharger install manual should allow you to extrapolate what they say to do with the lines and use that for this install. Shoot me a PM and I'll send you the TRD manual and the workshop manual if you need it too.

Hey SCary400, if I remember correctly Lextreme was the man who did most of the fab work for this, I think his plan was to port the supercharger to match... problem is that wouldn't work too well considering the amount of material that would need to be taken away (plus the cost would be a little on the high side).
