Aluminum Oil Pans (Z1 vs. CZP)

[kevinbonds]

I would go this Mishimoto route, sturdy shroud is your first line defense, I know from years of off-roading my Jeep, beat up skid plates. Weight penalty is minimal IMO. Don’t think I need to replace my oil pan, yet.

CZP shroud is best of the bunch on my opinion.

I have the CZP pan, yet to install it (waiting for next oil change), but it's an impressive piece of kit, fully machined and sturdy. It comes with everything you need(magnetic drain plug, high quality gasket) except Teflon tape which is only needed if you want to be extra sure of the seal on the extra NPT port. They said it's not required but also said it was NPT and not NPTF when I asked so I'm going to opt to tape it.

The included magnetic drain plug is also stronger than the Greddy one I had bought.

The Hex looks awesome also, reminds me of the HKS honeycomb GTR transmission pans.

I couldn't recommend it more based on initial impressions.

Just picked one up myself and can confirm the build quality is superb.

Getting it installed today, as I'm taking my car out for the season and going in for the oil change.

Super excited!!

I hope CZP makes an undershroud that fits the NISMO

I'm cheap. I decided to do the Dorman pan..... Price was at $150 forever. Now it is $187.

I got that oil pan and had it installed with an oil change. The drain plug is in a better place to drain all of the oil for every future oil change. It allows for slightly more oil and it’s a stronger material. The plastic oil pan was used for cost saving. This is a no brainer.for Z owners who care about their beautiful cars.

Sadly, comes out to be about the same after shipping.

I'd keep an eye on Amazon: https://amzn.to/4cqyF5t

I bought mine there in January for about $135 before tax with a coupon.

I have a question for those who have installed the Dorman oil pan. According to the Dorman website the oil pan bolt sequence is the same as Z1, but different from what ZCP recommends. Also, both Dorman and Z1 recommend a two step torque specs, 26/74 in.lb. Whereas ZCP recommends a four step torque specs, 26/74/108/144 in.lb.

I am getting a Dorman oil pan. What bolt sequence and torque specs should I follow?

Also, can I assume this oil pan will also fit a 2026 Performance ?

Use the factory torque specs. If the ZCP pan comes with their own bolts, their torque would be appropriate. If you make sure all threads are clean, you can put a dab of silicone sealant on the bolt threads. It will add a tiny bit of security preventing loosening but, will also aid in stopping corrosion between the dissimilar metals.

Forget Z1 or CZP

contact CJ Motorsports and ask them to make you one of these for the RZ34

Follow the Dorman procedure as you're reusing the factory hardware.

Yes to fitting a 2026.
