Twin oil coolers? - Widebody 1st gen S5 TII

Hey guys, reached the stage in my project where I am planning my cooling system and I was originally going with the traditional fb oil cooler under the rad, then decided to mount it I front the rad and opted for the bigger rad. The car is turbo and also will have AC.

But I was thinking that since I have a Mariah mode one widebody first gen and it's got these air scoops (designed/used usually for lights - which are illegal in my country as they aren't factory) I was thinking of using them for twin oil coolers?

The openings are approx 7.25" x 5.5" and I have been looking at the earls 19 row coolers which measure 8" x 5.75" x 2" with 10an fittings. I could easily fit a twin parallel setup and could even fit small fans on a thermo switch. I would run an oil thermostat and gauge to monitor it all to stay between 190-210* (hopefully)

I guess what I am asking has been asked (twin vs stock) but both sides have provided enough arguments to keep me guessing. But none of the examples were on a first gen as usually side mounts wouldn't make any sense, but I got these side ducts on my front bumper I think could be utilized. Here are some pics. (Please excuse the wheels and paint, they are just rollers and the paint is well... It's gonna paint soon )

The car in question

The front bumper, I hope to mount the intercooler slanted like this to trap more air in the front air dam. Getting a 30"x10"x3" one.. Anyway Couple pics down I'll try to show the 3" pipes coming out behind the oil coolers.

Here is a photo of the back/inside of the bumper showing the cutout for the proposed oil coolers

I got a package that measures almost the exact size of the earls oil coolers I have been looking at and the factory fender/apron mount tabs would be the perfect counting point. I was thinking I could cut the bumper more for some space or to angle the oil coolers. I was think I could cut them more and flare them to fit even bigger oil coolers. This I think would be the real and practical solution.

Here is how I was thinking the 3" intercooler pipe(s) would turn behind the oil coolers back to the engine

From the front.

I got the car with no engine and no cooling etc. So in either case I need to get an oil cooler and lines etc. I don't mind spending a more on the twin setup once it'll work. It'll look bad *** and utilize the bumper and free up some space (as I am installing AC as well). Thoughts please??

Here is my setup for reference to my cooling needs.

JDM 92 13BT w/ streetport
RA 2mm Super Seals, mazda apex springs
Atkins solid corner seals, mazda springs
New mazda side seals & springs
FD bearings and stationary gears, oil pres reg
Haltech, 800, 1600, BW S360 .88

Being built for weeks fun, Autocross and Sunday cruiser. Opinions and advice welcomed. Thanks.

unless you just want to go with twin/dual cooler system, i would think simpler is better in this case. even when fairly BIG power is involved i can't say i come across many people complaining about oil temps with the stock Gen II coolers. i think you should start with that and see if it handles your needs.

Thanks for the advice. I think my biggest issue if going twin coolers is the size coolers I can fit. All the modded FD's etc usually have pretty big side coolers.
