My motor has a oil-water oil cooler. Is it supposed to have one, I know Shawns dosent. After reading the rebuilding thread I got curious.

Yours is the 2nd that I've head has one. Mine doesn't. I'm not sure what dictated whether the car got one or not, but it seems to actually be a pretty rare item. Congrats! If you wanna sell it let me know.

mine doesn't

Weird maybe it was an option, Mine was all stock manual transmission car. Well except for the nismo ECU....

I know All FWD CA18DET with top mount intercooler came with the oil/coolant cooler, but some RWD did come with it, stange, that would be interesting to find out why and why not Nissan decided to go this way.The RWD ca18det that I stripped didnt' come wiht one, and that was kind a strange to me.

In UK ALL S13 CA18DET have it, in US, many automatic CA cars (i.e. KN13 Pulsar NX and others) have it.

It may have either been a factory option, or swapped on from automatics in Japan. But I don't even know if automatics had 'em there... I need to get around to trying to getting a full working set of FAST discs for Japan ver.

yeah, mine doesnt have one. im clueless as to why some would come with one and some not..

Ok, lets see if we can figure it out,

For the RWD ca18det guys that got there engines with the coolant, did you engine come with A/C OR NOT, I know all the FWD dets that I got they all had the cooler and they all had the a/c on them, may be that made a difference, can't see how , but possibly, The RWD det that I stripped it didn't have the cooler and it did have the a/c on it.The other thing, may be nissan figured that the cooler wasn't making much difference, and they scrapped it off in later years on. this way they would save money and at that time, Nissan wasn't doing very well and saving a dollar here and there would have made a difference on the company structure.

bla bla bla I am just fricking at work and bored.I thought I would throw more confusion lol

mine had a/c and no cooler. its an 89 engine if that helps you out. 5spd transmission...all that junk. and it was the freaking cool old school beige/white 2 tone scheme.

Post by **pulsar gtr** » Thu Mar 04, 2004 5:32 am

Did any one get there engines without the A/c on it, (don't mean the a/c was lost some where on the way to you, but the car was manifactured without one?

Mine had AC. It could have been a factory option or a heavy duty model. Like I said my car was a freak, All stock (dealership service) not even a aftermarket filter. It was fully optioned and had the Nismo ECU in there. There was a turbo timer that was hidden in the trim under the lower cover by the steering wheel. The world may never know. Mine was also a mettalic blue if that counts.

Jon's is the only other one with an oil cooler.

JDM one's didn't have them. UK/Euro models did.

my RWD does

Post by **PacManVR4** » Thu Mar 04, 2004 5:32 am

I dont belive the Uk thing, I think they were an option and very few got them, we need to ask TMS. Main thing is that my ECU says 'Nismo paddock in Chiba" on the cover of an otherwise stock car that hasent had the ECU pulled till I got it. Anyway why would flashoptions or any importers for that matter have UK spec stuff? It defeats the point.

Post by **minutericesentra** » Thu Mar 04, 2004 5:32 am

My auto pulsar w/ a/c has an oil cooler(first pic) and my DET that's supposed to be from a Bluebird doesn't(second pic)I don't know what kind of options it had or whether it was auto or not.http://community.webshots.com/...xrNflh ... m/...TyPGo

Does anyone have the oil cooler and secondary intake runners? Because it kinda looks like there just might not be enough room for it on my DET because of the runners.

Post by **slw240sx** » Thu Mar 04, 2004 5:32 am

i have a JDM spec motor with variable intake ports and the oil cooler

Post by **CA19DET** » Thu Mar 04, 2004 5:32 am

Quote »JDM one's didn't have them. UK/Euro models did[/quote]^^ Both my JDM motors (DE & DET) came with them, both RWD and w/ AC, all CA18's i have seen (all JDM) have the oil cooler, even the FWD ones in B12's and bluedirds...

Post by **cuzan0** » Thu Mar 04, 2004 5:32 am

mine is also a JDM spec motor with variable intake ports and the oil cooler also cam with a/c

I think someones been selling yall bunk motors

Post by **r34 gtr** » Thu Mar 04, 2004 5:32 am

haha. hope not. anyone know how much of a difference it makes on oil temperatures? im kinda wondering how well they work..

Post by **diamondstar36** » Thu Mar 04, 2004 5:32 am

Honestly I doubt it makes much of a difference. The external oil cooler that came on '90 DSMs is a very coveted piece over the standard water cooled version in the later years. It's said to be more efficient and less troublesome. So whether you have it or not, it's hardly worth getting worried about.

Post by **r34 gtr** » Thu Mar 04, 2004 5:32 am

alright. im not going to go find one but was just wondering about its efficiency. thanks!

Post by **NeedCAforS13** » Thu Mar 04, 2004 5:32 am

neither JDM motor I got had oil coolers... the DE I'm using now, and the DET that blew up were both a/c equipped (bracket was there at least... someone removed the power steering pump and compressor though:( ) oh well, as long as it doesn't really make a big difference I'm not too worried:)

For 'normal' conditions a water-oil cooler is best, as you get up to operating temperature faster and still keep it within operating range; for 'hardcore racing' an air-oil cooler is better, because you have more heat to get rid of, and this is great for getting rid of it fast.

Of course your oil temps will go up and down as the oil thermostat opens and closes using the air cooler, a water cooler they'll stay somewhat similar to the water temps, which will keep them both close together and also keep both from wavering too much, hopefully maintaining a good operational temperature for the engine, but of course limiting all cooling under greater load circmustances to that available to the water cooling system.

An intersting idea I've wondered about and yet to see tried (altho it may have been) would be using an water-oil cooler AND a air-oil cooler; the water-oil would help maintain temperatures in the block via the oil and water at a proper heat range, and the air-oil cooler could be thermostated to open a little later than normal so under heavier loads it benefits cooling, but not until then, and the water-oil would still help mediate temperatures fluctuations and heat load(the additional cooling of the oil would also contribute to less heat in the water, altho not at any great efficiency it would help to act as a secondary water cooler).

Of course this would be kinda complicated and all, ... it's just crazy enough

Turbo automatic CA18DETs in Silvias and 180SXs came with a sandwich water cooled oil cooler. The swap onto one not so equipped, I put one on my Silvia's CA18DE

Post by **biosehnsucht** » Thu Mar 04, 2004 5:32 am

Well then that sounds like any motors from Japan w/ cooler are likely from originally automatic cars just like in the US (either car was converted to 5spd, or the oil cooler was added, or the engine was swapped); of course in europe just about everything (manual and automatic both) have oil coolers.

yes, altho at the time the album came out, the title fit me, after having translated the meaning...

and uh, how bout them 'coolers? (sad attempt to get back on topic before we get any further off topic)

Post by **pulsar gtr** » Thu Mar 04, 2004 5:32 am

Ok, I believe I have figured it out.

I picked up a RWD ca18det for a customer on this forum, and it does have the oil cooler on it, what I noticed is that, the power steering pump had three nozzles, which indicates that the car where the engine came from had HICAS AWS, and since these hicas cars weren't as popular as the regular 180sx, hence making them rare to find, which makes the engines rare to find with oil cooler.

Please applause.

Thank you

yes i forgot to emntion that my DET came from a 180sx with HICAS AWS... hence the oil cooler..

but my Stock JDM original CA18DE Auto Q's S13, cale with oil cooler, no HICAS AWS, no ABS, no LSD...

go figure.
