couple of intercooler questions

[1966 dart wagon]

Im looking at upgrading my intercooler this year, sometime soon. Anyways cars specs of now:

89 daytona cs 2.5(all the TII stuff on it) garrett turbo 23psi, stock ic, 1pc intake, stock tb, 3in exhaust.

Im going to be upgrading to 83lbs injectors(40+s cant keep up with e85) running probably even more boost...ya im getting greedy/addicted, plus upgrading to a t3/t4 turbo hopefully this summer, and would like to keep this intercooler when i build my 2.2 motor with either the t3/t4 turbo and put out 350-400whp, that is the loooonnnngg term goal(2-3 years). Also this year before my turbo upgrade(stocker) id like to hit high high(12.99) on slicks no weight stripping (2700lbs dry).

Anyways I got a quote from a local shop today to make me intercooler piping, going to cost 325-425 depending on bends and type of couplers used(how does that sound). Should i go with 2.25 piping, or just go to 2.5 since i do have a 52mm tb and it will be installed down the road. Should i just go all out now and get the spearco, or will an ebay suffice?

Nobody??? I checked out some other threads but didn't really find the answers i was looking for. also the car now has a 2.5 sv, but Im on the order list from chris to get a 3in one

With intercoolers I look at cross section the air will see.

Intercooler A 22.5x3=67.5
Intercooler B 18.1x2.75=49.8

Now they both have similar construction, so to my eye without testing then the intercooler with the larger cross section should have the lower pressure drop.

if anyone has had good luck with a specific intercooler feel free to post up specs and feedback of it, I would gladly appreciate it
