I was thinking about upgrading to a dual oil cooler kit and was wondering what brand/kit y'all recommend i buy

Your best path will be to build it all yourself. there are "kits" available but making it for YOUR set up would be best. its not hard.

for the most part, any name brand cooler will work. it just depends on what brand you want to claim honestly. we prefer the mishimoto 19 row because of its value and how well they work. also having the 10an fittings built in is nice in addition to all the color options. we use their thermostat as well for the same reasons. we have shifted to using push lock over AN not only because of the cost but its easier and faster to assemble, has an oem look and is low profile. mounting the coolers is pretty straight forward as they need 1 Z and L bracket each. Very easy to make if you have the ability to do an oil cooler job yourself. the thermostat can be mounted on the bottom of the driver side frame rail.

the lines can be ran under the bumper or in the sway bar area. just depends on how clean you want the install to be. there are quite a few threads on doing a twin cooler set up so you should be able to find all the info you're looking for. we do intend to offer a complete kit one day that will be the most unobtrusive and universal to ANY FD set up. thats not for a while though lol

Option #2 of course is finding a good set of R model dual coolers. Usually they’ll require a little fin combing but plug n play if you’re like me and have trouble fabbing a ham sandwich….or have a super-original car and want to keep it that way. Be sure to get the ducting for the second side. Either way I think it’s certainly worthwhile.

^That's the exact route I took, and it provides more than enough oil cooling in a street driven FD. Even if I'm flogging my FD with lots of revs & boost on a hot 90*+ F day, I've never seen my oil temps go beyond ~195*F or so. Unless you spend a lot of track time on long road courses that push oil temps really hard (i.e., courses with really long straights where you're flat out much of the time), I think the OEM R1/R2 oil coolers & ducting is perfectly adequate.

I've been curious about this Touge kit, but haven't seen any write ups.

The site also has plenty of close-up photos that give a pretty good roadmap for rigging one up yourself.

WARNING: during winter if you do not block off the secondary cooler, most likely your oil temperature will run too low.
This happens even with the stock R1 oil coolers here in Houston.
Search it or test it with temp sensing stick ons during winter.
One where the oil leaves the front cover and one on top of the oil filter.

Twin THIRTY row coolers on a street car is a mistake.

i'm using sakebomb garage dual oil coolers. 19 row setrab with nylon braided lines.

I’m with you. Picked up the 25 row Sakebomb kit (setrab coolers). Haven’t looked back.
Everything is included in the kit and the install is fairly easy.
plus, if you ever do go to the updated 99 spec bumper or any other bumper with larger openings, the mounting hardware is all included so you can rearrange accordingly.
She runs extra cool now and I never have to worry about overheating.

I have had good experiences with the Setrab 19 row coolers. I purchased the Sakebomb kit but looking back and knowing what I know now, I would probably just make my own next time around. Still need to figure out a ducting solution for them with my series 6 front bumper. Additionally, FWIW, I recall reading somewhere that back when the Pettit was competing in endurance racing, they were able to run several Rolex 24 events with the stock dual oil coolers and allegedy had good results with them. Purely anecdotal, I know. If you happen to locate some in good condition for the right price and you have the factory ducts, I think it still is a pretty good option all things considered. They also have integral thermostats so you won't have to fabricate something to hold it like you would a remote thermostat.

I had a similar experience as Chuck did in post #6 and my oil temperatures would not get hot enough when it was cool out back when I was still on the stock twins, which I would imagine would have had an increased thermal load on the coolers. For a street car (and probably a single turbo race vehicle) I personally would not go any larger than 19 row. Only exception IMO would be a turbocharged 20b. I helped a buddy build his and we chose dual 25 rows and I don't even think it has ever passed 185 f.

I too had the issue of my car not getting hot enough with aftermarket twin oil coolers. I have 25 row coolers and even on average days here in so cal my car was still too cool for my liking. I didn’t like having to run a piece of cardboard in my bumper so the car could warm up… so My fix was to change the Mocal thermostat to an Improved racing model instead and it did the trick.

Various old school guys who do 8s in the 1/4 as well as endurance race rotaries say that you can do WOT pulls at 100-120* oil temps without any issues. Has anyone here actually ran into problems caused by oil temps being too low?

I feel like it probably depends on bearing clearance.
