I have enough for one but not the other...
 

So I need to know which one is more prudent in getting done?

The modified CSC or the Oil Cooler? I'm going with Z1 for either of them and will be taking the Z to them to install the CSC when it's time(tried to get them to do it this week before I leave for New York but they're booked up :shakes head: so I guess I'm gonna do one or the other when I get back. So which one do you gents believe is more detrimental?

My thoughts were the CSC since it can go out at any time and the oil temp can be maintained by just staying out of the throttle or letting her cool down.

Lemme know what you lot think!

I've done both. Actually changed out the Csc and Master cylinder before utter failure. Use Motul 600 when you do it. Caveat on the Oil Cooler....with a 25 row it can take some time to get to 180 on your oil temp. Made a huge difference on hot days this summer. Completely solved any overheating issues. But as it gets cooler it can take awhile to get or even stay at temp if you are driving mellow. Free advice and its worth just that. CSC first aI would advise. But you will need both eventually.

Just get a thermostatic filter adapter , it won't open til 180 and it solves that problem.

Farm out the csc first and then diy the oil cooler.

Got it. It works. Maybe just the higher volume of oil = 1 quart. When I installed the plate and cooler there was no defining way of attaching the hoses. I have wondered if I have it reversed and the themostat is not even in play and it runs in an open loop. There was no info I could find and the info I did find said the hise attachment did not matter and was not defined. It is a good problem to have...might check that out the next time she gets lifted off the ground.

I think the CSC and master cyl. install was $700 plus at Nissan dealership. Oil cooler is definitely a diy afternoon project.

I planned on doing both somewhere along down the line but didn't know which one should be done first. Logic dictated that I do the CSC first but a fellow who is about an hour from me was telling me that I should do the Cooler first so it kind of caused some confusion.

You can drive the car as is without the cooler for now. Slave goes and you have a gorgeous yard ornament that will start. Hmmm..

Maybe not even start actually due to the failure. Still looks good though

$700 is what Z1 quoted me for the labor.

Out of curiosity I called my local Nissan dealer and they wanted $1200 for labor alone. It took all I had not to horse laugh him.

As far as the Oil Cooler goes, a guy at my work(I work at a Stealership, lol ;) ) is going to do it for $50 one evening when we've got down time.

Yeah, that was my thought process too. It didn't make much sense to me either but I thought maybe he knew something that I did not. Apparently I was mistaken about his sense of priority.

Thats a fair deal from the guy at work. A small price to pay for minimal stress. 1200 seems very high or I went to a cool dealership. It was supposed to be covered under my extended warranty but of course it wasn't.

Keep in mind most stealerships won't touch aftermarket parts so likely the quote they gave you is to swap out the pos csc for another pos Nissan csc. Go to Z1 and have it done right with their elimination kit, or take a look at the Zspeed option imo. An oil cooler is another necessity but it won't leave you stranded in the middle of no where unlike when you csc goes out.

Thats good advice. I installed the Z Speed based on alot of other good advice from forum members.

CSC.

you have less control of that failing vs. just driving more conservatively to deal with heat. It surprises me that some people will fork over more for an exhaust first.

But at the same time, you ideally should fork for the clutch and flywheel since the transmission has to be dropped and you're already spending on CSC and CMC. Helps with the response and vague clutch feel of the car. You shouldn't be charged any more for the labor either.
