SMIC with stock airbox, batter & piping.
I'd like to keep my car as stock as possible -- retaining the original battery tray & airbox, but would like to run a larger-than-stock intercooler.
Which one am I looking for?
Blitz? Greddy?
Are there any good better-thab-stock SMICs that are drop in?
Ideally not requiring their own pipes either.
Or am I looking for a unicorn?

Greddy, Knightsport ,SR motorsports, BlITZ, if you're lucky enough Mazdaspeed should all work. Pretty much anything similar to the Greddy SMIC. I am not 100 % sure about the stock piping though. I have an SR Motorsports SMIC.

Pretty sure GReddy and Blitz require modifications to the duct that are visible. Not certain on the KS and SR, but I think they do too.
Finding a true Mazdaspeed SMIC might be tough. I THINK the ARC was pretty much identical (they might have even been the supplier of the MS SMIC), but I don't think either one was much if any larger than the stock IC. I want to say that the big selling point was that they were all-metal and welded. I vaguely remember an article from way back in the day where the stock plastic IC's had developed leaks from higher-than-stock boost levels and heat.

It's pretty hard to get too much larger than stock in the stock location with top/bottom end tanks due to the geometry and space available. The Greddy SMIC manages to get a core in there that is nearly 3X the stock volume... but comes with the cost of a circuitous air flow path and very narrow end tanks (the bottom tank is ridiculous). Core volume does not necessarily = higher efficiency or lower pressure drop... though it does help.
For near stock packaging, the Aussie U-type intercooler looks like the best compromise... not sure of how to get a hold of one, though. Don't know if you can use it with a stock air box either.
Once you get an IC in there that actually works, things aren't looking stock anymore... so why constrain yourself with the oversized stock battery and intake?
Good info here on the older units still bouncing around: Intercoolers

I used the RP one both with stock airbox and with open element dal Blitz air filters using '95 Y- pipe.
I am using the huge M2 unit now with M2 narrow airbox and relocated battery which uses the old '93 Y-pipe.
I miss the old set-up with the small stock sized IC- it had much better response and felt like more primary turbo power.

You cannot beat either the Knightsport or the Australian U-type SMIC (which I have) for size and efficiency. It is hands down the best for size vs performance in the stock location. These have 5X more surface area as compared to stock and have the double cooling effect on top of its greater surface area (U-type style).

No I haven't. I have only tested efficiency. I have not seen any specs on pressure drop on any of the U-type IC's. Knightsport has some efficiency testing stating a 30 degree C improvement in temp drop on their dual bank U-type IC as compared to a single bank.

It's correct that lowering pressure also lowers temperature, everything else remaining constant. However, no one I know wants to lose more boost pressure than they have to across the IC. In a device such as an IC, the temperature can decrease while maintaining (most of) the pressure. What ideally changes is the density of the air increases while pressure remains as close to constant as possible. That, along with reducing the high temperature propensity for detonation, are, IIRC, the 2 main reasons for having an IC.

The pressure drop and efficiency are tied together somewhat by the ideal gas law, which states that temperature is determined by the pressure in a fixed volume. If you have to start off with 14psi air at the compressor to get 10psi at the manifold, your IC inlet temperature is going to be higher due to the higher pressure required to overcome internal resistance to flow. The intercooler has to work harder just due to the increased inlet temp/press and will show a lower efficiency.

ARC makes a stock mount IC, i didn't look at the price, but they seem to be available new

Because the RP smic core is thicker than stock the lower IC hose can rub the accessory belt. I fixed that by putting in a silicone lower IC hose.
Also the inlet/outlet were a bit too big diameter which sealed well with the old blown out stock couplers, but made putting new stock or aftermarket couplers on a bit of a workout.
You could pay more for something a bit more refined, but I was quite happy with the performance of the RP smic.
