Been doing some added research on putting an intercooler in my '94. In some respects I'm wondering if I chose the right direction to head - materials wise.
I've gleaned over the two threads here on IC installs, as well as looking at a couple of other sites - forums and vendor, and a printed article I have on the install of a Turbonetics system in a 6.5 Blazer. For reference purposes here's what I've looked at and gathered info from:

First, the 'original' 6.5 IC kit appears to be from Turbonetics. The IC core I'm guessing (as I have yet find listed dimensions) is about 20"w x 10"h x 3" d. Compare this to the Large IC core sold by Kennedy (Spearco) - 25"w x 6.5"h x 4x5d, and the IC core used by our own MrTailLight - 24"w x 12"h x 3"d. The Kennedy(Spearco) version and MrTs' version are both 'bar and plate'. It is unknown whether the Turbonetics used bar and plate or 'tube and fin'. From a volume perspective we have MrT @ 864 cu in; Kennedy/Spearco @ 731 cu in; and Turbonetics @ 600 cu in. (Understand that this is a physical dimension reference. I was to find flowrates for the Kennedy/Spearco IC only. Flowrate would have made for a better comparison.)
So here are some questions to ponder:
1) How much air flow (flowrate) or volume is required by the 6.5 Turbo?
2) Can an IC be too big? Or too small?
3) For each of the IC,s how much of the actual IC core is out of the 'direct flow" of oncoming air? That is to say when looking at the front of the truck do you see all of the IC core or only a portion?
a) If you only see a portion, would a longer (l-dimension) but narrower (h-dimension) and deeper (d-dimension) be better in that it might expose more of the core to oncoming air.
4) Tubing size - is it best to keep the diameter the same as the turbo outlet and intake?
5) What are the pro's and con's for each - 'bar and plate' and 'tube and fin'?
6) What is an exceptable pressure loss across the inlet and outlet of the IC?
