I have a 99 GS-R that I have done some major mods too. I was looking into adding an oil cooler and after researching I have noticed that my car should have been equipped with one from the factory. Anyone know if this is true of all GS-Rs or just an option on them.

I don't think the oil-to-water cooler was sold as an option, but I have seen late model B18C's that do not have it. :thinking:

If you're concerned about oil temps, I would look into buying a sandwich adapter, AN hoses and an external cooling radiator.

Call me a skeptical bastard, but I distrust oil-to-water cooling setups after seeing the aftermath of one leaking internally. It wasn't on a Honda motor, but main bearing failure and a blown head gasket were just the start of the problems.

do u have an oil temp and oil pressure gauge setup?

what major mods do you have, and what kind of driving is this car is exposed to?

Factory oil coolers only came on 94-95 GSR's and all Type R's.

Yea, the idea of an oil to water cooler doesnt sound good to me either. Glad it doesn't have it so it's that much easier to install an oil to air cooler. I do have an oil temp and pressure gauge set installed. On a day at the track, oil temps reach close to 260, which is why I was looking into a cooler. The car sees mostly track time and I'm pretty hard on it, but that's why I built it.

The mods are:
Dart B18 block bored and stroked to 2.2
Crower billet steel crank
Crower stage 3 cams
Crower rods
Crower valvetrain (SS valves, springs, rets)
Crower 12:5 cr pistons
Toga high volume oil pump
PnP head
Edelbrock IM bored to match oversized TB
Warlboro FP
Bored out fuelrail w/modified regulator
RC 440 Injectors
Custom header
Greddy Evo2 exhaust
Fluidyne radiator
Custom tune

wow, thats a healthy list of mods.

good to see an integra owner doing track days.

260 is pretty high, so get that oil/air cooler in there.

dont know any places off the top of my head where one can easily mount.

MFactory makes a reputable oil cooler. Do a google search, or check Honda tech. I believe the unit runs for $300 or so.

I will check them out, thanks.
