i think it's a great idea.... pre-drilled for external cooling is helpful... otherwise people have to take a chance drilling the oe unit

I'm not sold on the value of making a new diff cover. I think the Nismo version is sufficient. Are extra bungs really going to make that much of a difference? Diff cooler setups work fine with the stock bungs. It's easy enough to add a T if you want a temp sensor.

Sure, I would pay a 25% premium over the Nismo cover for a nicer version; maybe even 50%, but that doesn't even get us to $200. And it's a pretty small market to compete against an existing part.

Or look at the Grand-Am teams. They have a much much larger budget and they have not seen a need for this. Love your stuff phunk, but I don't think this one is worth your effort.

The problem is that there are no nismo diff covers. Try buying one tomorrow-they don't exist, and haven't existed in months. Nismo USA doesn't give 2 sh1ts about anyone of us is what it boils down to. If they did, they would be making the f-ing parts we need to make this car go faster. They are focused on the GTR market not us. If they were smart they would warranty replace the oil cooler problem and then build a nismo turbo kit. but when your golden boy and your marketing department suck at fast, just expect to get pimped.

I'll buy a diff cover with some extra cooling capacity tomorrow for 450 from anyone that can send it to me because it is holding up my LSD install.

^ well said. The Z gets no attention even from the US market where money can be made. Then the companies that do take a lifetime to produce. By that time the next model is out.

This is totally open for suggestion. This was just the preliminary results of messing around, and I am sure the part will change a lot before we machine it.

So, looking for feedback on this!

Got some mild cooling fin work there... theres not much airflow in this location but even those fins more than doubles the radiant surface area in the location.

Some of the radius are unrealistic to machine in, and the thing might look a little more boxy before its said and done.

Anyways... some of the first steps have been taken!

I know I said I would post a new thread yet... but I guess I am not ready to take on a ton of attention for this right now. I would rather have a more solid footing.

After looking at this, I would like to see a 1/2 - 3/4 inch spacer and the stock cover??? If there is more room under car a full inch? It would keep the cost down

phunk 01-07-2014 03:59 PM

Unfortunately there is a mount location on the cover, so it cannot be spaced. ABS sensor mounts too.

None have shipped out yet. They should be headed out this week. I began assembly of them Thursday or Friday and ran down the entire parts list and ordered up everything small that I didnt have enough of, and it all came in the other day. Yours, along with the other 3 paid units are in their respective shipping boxes about 70% assembled. I was actually going to start finishing them up this evening!

I can probably get yours out tomorrow if you wish. I will post up if I have any issue finishing your kit this evening.

edit: sorry I did not mean to ignore your post early when I was on here. My previous reply in this thread was posted from my phone. I was sent an email with a comment about the spacer, and I replied to it from my phone without realizing there had been more posts above it that i didnt read.

phunk 01-08-2014 03:30 AM

Welp... one part prevented me from being able to complete shipment on RRPs tonight. I just ordered it. It should be here Thursday hopefully.

Any thoughts on making an oil pan? The GTM one looks pretty good but with all the problems GTM has I have to wonder if it will ever make production.

The GTM pan has been ready. It would ship out same day if you ordered it. But that pan really serves no purpose than the baffle design. A oil pan spacer is all you need to gain quanity. When added up a 34R cooker and Spal fan orb ding where you live is all that's needed. But a average oil pan with baffle would be nice.

The biggest problem which isn't huge is We need more people buying to get cost down while supporting a real enthusiast as Phunk that gets things done. All these tards buying these crappy body kits and interior CF junk with what money they do have instead of real true potential performance parts. In which this is what the car was intended for.

The CF pieces are the best. Nothing says rice like "The whole point of this stuff is to save weight on an expensive car, but I'm actually *adding* weight to my car by layering it over something else."

Let's not forget the cheap Taiwanese coilovers so you can slam it on the ground, yo. And fitting 225s onto 10+" wheels. :rofl2:

An oil pan has been on the list for a long time. I sort of stopped thinking about it on a personal level since what i am doing with the oil pump will almost definitely use a custom lower oil pan anyway. While I have personally not been a big supporter of the aftermarket pans... Its not up to me to decide what everyone else wants, and I have to have wide open arms to that.

Having been designing fuel systems for too many years now, i have learned a lot about fluid control systems and I could probably build a pretty rad oil pan. Oil pan would be much easier/cheaper than the diff cover because it doesnt need to be totally solid billet since there is no load on it. That diff cover, since it has the rear diff mount on it, needs to be BEEF.

Now.. you guys have asked another vendor besides from GTM to build an oil pan also... so I need to choose wisely where to put my efforts. Its easier to play nice and all construct different products for a car that lacks so many. But then for some products, there is plenty of customers to go around and its not a big deal. So it all boils down to interest.

I have a 370z here, and I have the ability to manufacture just about anything for it either in-house, or through close contacts. I am total wide open to building anything that is asked of me.
