The only silicone coupler I could get in town was a 3"-to-3.5", which I could NOT, for the life of me, get onto the LQ4 throttle body. I searched on eBay and bought a 3"-to-3-3/4" 90° elbow, which should be here in a week or more. In the mean-time, I threw a hose clamp on the 3"-to-4" 90° just to see if would even remotely tighten. Oh. Interesting. It does up and holds tight. Hmmm. Figures.
So, I piped the rest of the cold side, and since this picture was taken I welded the blow-off-valve mount in place. I have also spaced the rad out 1.25" to theoretically fit an AC condenser between the rad and the intercooler.
