The billet aluminum CJM Active Baffle Oil Pan for the (07-08) 350z & (09+) 370z was constructed to improve on the lubrication system of your VQ engine.

Integrated within the pan is a separated sump area surrounding the oil pump pickup. Active 1-way trap doors allow engine oil to easily enter the sump area yet greatly slow its departure during high lateral-G maneuvers. Vertical longitudinal baffles guide oil returning from the rear of the upper pan into the sump area.

Improvements to oil control will contribute to longer engine bearing and oil pump life by reducing the tendency for oil pickup starvation during aggressive driving sessions.

Oil capacity is increased over the original pan roughly 0.5 quarts by increasing the sump depth (the most effective way to increase capacity while adding additional fluid control and starvation protection). Overall depth was intentionally left above the front suspension cross-member to keep the oil pan within the factory lower engine shroud and out of harm's way from road debris. The additional oil capacity will contribute to stabilizing oil temperatures and increase oil quality life between changes. To take advantage of the extra depth, an oil pump pickup spacer and extended hardware is included with each pan.

Additional surface area is added to the lower side of the pan to aid in air-cooling via a heat-sink effect.

The drain plug location was moved to the rear bottom of the pan to improve oil draining when the front of the vehicle is lifted on jack-stands. A low-profile drain plug is included (-6AN threads, 9/16-18) with 3 reusable high quality bonded o-ring drain plug washers.

Each CJM billet oil pan includes -10AN port fittings on the left and right sides. These ports are mostly intended for turbo oil drains. The pan can be ordered with plugs or -10AN fittings for these ports.

Stainless steel cap screws and washers are included to secure the oil pan to your engine.

Thanks!!!

Will work with z1's undertray?

This oil pan sits higher than the crossmember, so unless an undertray intentionally raises up higher than the crossmember, they will fit together.

It sits right above the cross member so...Since the under tray attaches to the cross member, I bet it would

I'm leaving work soon seeing if this will fit into my budget

I am in ... refer PM on oil pickup ...

:iagree:

Is a spacer included for the pickup? Very nice job Charles looks great.:tup:

How much oil does it hold? I have a few friends here in Taiwan that want it.

In for one as well. Also would like to know if youre extending the oil pickup.

Sorry for slow responses today has been a long one! Any time I get batches back from the anodizer, the rest of the day is crazy. Also had to get another big batch of parts ready to drop off during the pickup. I almost dropped off this pan! But I think I'll leave it pretty for a while longer. I was thinking maybe like an olive green color or something out of the ordinary black and blue I always do.

I will hopefully have oil capacity increase measurements this week. As soon as I get my hands on a stock pan to measure its displacement I will know the difference/increase.

As for extending the oil pickup, yes! That is another reason I need to pick up a stock pan. I want to lower it to have the same vertical clearance over the floor as stock.

Anodize it black - better heat dissipation ....

I'm in, but i want it raw. would rather clearcoat it with powder so it stays pretty, even if only me and Z1 will ever see it

Excellent! I will let each buyer decide if they want it straight from the CNC or anodized. I figured most people will want such a large billet part to still look billet and it really is so cool to handle and look at. I'll probably make another for myself to just keep around.

For the 6 screws securing the baffle lid, I was figuring on providing pre-drilled safety wire screws for anyone who wants to use stainless wire on them as an added security. I was thinking of having the laser put a U notch about 1/2" from each one to hook the wire around.

Charles - I would drill each fastener and lock-wire them together in a daisy-chain - I do this in several places on my race-car for security - implies you have (or have access to) lock-wire pliers (which I do).

So much want, is this going to be something that can be ordered on an individual basis? Car is about to get the 2015 nismo conversion painted and blended.

This is great! I have the JWT spacer currently since I have turbo lines plumbed in there. I wish I didn't have to re drill this one. Any chance of having it predrilled prior to shipment? I would be interested in this pan plus the billet gears.

In a week or two we will compile the list of who all is *IN* and I will then propose the manufacturing schedule and take material only deposits. I will probably produce 3-4 more than what is pre-ordered to keep around for late arrivals.

Yes I would be willing to CNC the ports for a rather small labor charge. (It will entail mounting in the CNC from positions otherwise unnecessary)

Well actually, maybe I should consider just making it part of the standard process. I dont know. Generally I would prefer they not be there if I dont need them... but I am thinking that since there are moving parts in there, perhaps some big ole -10 ports would be nice to have as little windows to look in and check on things every few oil changes? I cant imagine what to see, but I would look anyway LOL

This is art, but has anyone built a baffle for the stock pan. I may be able to afford that. I use to have access to NC mills. I miss them.

phunk, I TOLD you that there would be interest in the pan. And the price. That's damn good.:tup: The AM Perf. pan sold for $1200 new. Used ones was going for $500+ IF you could find one.

So how much are you talking when referencing material costs? I could probably do this right now then. Pay for the material right now and upon completion pay for the remainder? I would need a hard "deposit/material" price to run by the boss lady.

I think I am in. How did you deal with the sealing surface at the pan lip? Did you notch out a groove for the silicon sealant for a better seal? This is something Nissan has always done on timing covers and 2-piece oil pans.

In for this.

I would probably just round it out to $100 even. Like when I did this with the road race pumps, I would set a sizable amount of time to pay off the part after production so people can fit it into the budget without forcing it through. I would probably hold the pan up to 12 weeks after production with the deposit.

I considered doing that, but I didn't do it. But I sure can if you like that! I can take the same ball cutter that worked in the heat sinking surface on the bottom, and run it a little less deep to create a valley inbetween the bolts.

Another thing I plan to add to the production pan is a recess in the flange for pounding in a pry tool for removal without banging up visible surfaces. I also thought about possible a threaded hole or two to threads bolts into that push on the upper pan to ease later separation.

Thanks for the text message emotion support! From what I found on the forum, I think AM only made 4 pans for customers

Also thanks to FL 4motion for reminding me to make this last week. I had the material sitting around forever.

Yes, I would like that. I also like the idea of at least 2 pry points to get the pan off if needed without damaging it.

Ready to send money. Pm me when you are ready.

Far as supporting mods go, Is this pan more for people who intend to track their Z's at anything above 7,500 rpms?

When you have another emotion break down. Feel free to text me. :D

AM made about 20 pans. Think 8 was for the race cars, and the rest was sold to the public. Maybe 6 forum members have one.

It's beautiful Phunk...expect a call.

Information moved to first post

this pan prevents oil starvation in sustained hi g turns on the track. It helps lower the chance your engine goes boom. It also prevents oil sloshing to and fro as you zip thru the shorter back to back turns.

Nicely done Phunk. :tup:

No maybe, I am in.

Tail of the Dragon......at 7,000rpms.:eekdance: While your passenger does this :barf: and you don't want to do that because the motor went pop.

Damn you Charles. Every time I think I've gotten the built motor fund needs figured out you go and release something else I 'need' :ugh2:

Charles did you ever determine the increase in oil capacity of the new pan. I'd be interested in one but I'm running the Wolf pan spacer. I don't want to loose too much oil capacity by going to this pan.

Not yet, I still have to find someone local with a pan. There is a shop about a hour away that probably has one but I havent had time to get up there yet. If the spacer doesnt put your pan past the crossmember, you wont lose anything. Even at the same depth this pan will hold more due to its straight walls to the floor opposed to large radius.
