Same side FMIC inlets. Which to pick from?
Well, I am finally going to go ahead and do FMIC. I just dont really trust the meth/water for some reason. I am doing same side inlets since it will be alot less piping. Now, i have two intercoolers to pick from.
This one is same side inlets, but the bank on the left dosnt seem to be a great flow its just squared, so air is going to make that sharp 90* turn which i dont like. Overall Size: 27"x11"x3", 3" inlets
This one is meant for a twin turbo, but I would connect one side with like a U coupler or something and turn it into a same side inlet IC. Its alot cheaper and I think it would flow alot better since it dosnt have that sharp 90* turn as the one above (since i'll have a U bend on that side). Overall Size 30"x11"x3" 2.5" inlets
What do you guys think? would the 2nd option work well? just connecting one side togethere and use it as a same side style?

What you need is a vertical flow IC like this:
That first intercooler design is just crap overall (I can't imagine the pressure drop that thing must have, assuming the inside of that first endtank is as I'm imagining) and the 2nd one as you suggest setting it up is bad too (but not as bad as the first one I'd say, at least if you use a connector pipe to connect the left side tanks together there will be a velocity increase that will help draw the airflow through the tube and back on its way out of the IC.)
The vast majority of cooling occurs in the first few inches of the tube. Using those intercoolers would have you effectively running about a 5.5" tall, 48" long intercooler because you'd be running the air through the entire length of the IC twice, but only using half the height of it. With the first few inches doing the vast majority of the cooling, the rest is just pressure drop city.
Vertical flow intercoolers have many more tubes that are much shorter, meaning that a core of the same dimension has much more efficient cooling and less pressure drop (pressure drop is a function of tube length, the shorter the tube, the less pressure drop).

Ok thats the explanation I was looking for. Now that you mentioned the first few inches being the majority of cooling, that makes me think of just running a traditional IC, and that way i keep my bumper support and fog lights, since i'll have to remove the support if i do any of the IC we have mentioned here. Thing is, what size core should i be looking for? does it depend on my turbo and how much boost i'll be running? i am looking at this one now
Overall Size 28"x5.5"X2.5"
Core Size 21"x5.5"x2.5"
2" Inlet & Outlet
2.5" Thick Core
Now that you have removed those two i posted from my mind, I would def go with vertical flow core same side inlets, or the one im asking about now.

are you planning on adding more power or are you sticking around your 260ish hp that you have now? If you are sticking around that power level then i think that small one you posted would work just fine, but if you are planning on going upwards of maybe 300whp, I'd get something a little bigger like maybe 8" tall, you can still keep your bumper support with one that size, might need to cut into it a tad, but I doubt it. Probably want to get out the measuring tape for that.

I would like to suggest reading "Supercharged" by Corky Bell. He has a whole chapter dedicated to sizing the proper intercooler for your specific application, what are good end caps, what are bad end caps, bar vs plate etc etc. Lots of good info.

I monitored my intake air temperature for the first time. temp was at 123F!!!!! outside temp was 76F
I found part of the reason why the temp is so high. my charge pipe comes from below the tranny and up behind the driver said fan, then to the MAF and TB. basically the driver side fan is pushing uber hot air directly onto the charge pipe all the time. So im thinking about making some kind of shield so the air coming off the fan dosnt hit the pipe directly, maybe this will lower the intake air temp a bit.
(ofcourse still doing IC eventually)

I'd suggest you pick up an OEM 89-92 Supra Intercooler for $50-$75. Should suit your setup nicely.
I just sold a used three core Procharger Intercooler with 3" in/out for ~$230, and a similar Spearco model can be had for about the same price. Either of those as an alternative to the very capable Supra OEM, or a no name ebay model.
