Just the raw block of aluminum for our pan costs more than an imported cast part. I would vote that our pan is a more practical size. Personally I am not a fan of the giant wings on the GTM pan. I wouldn't want that on my car. Different strokes for different folks!

So if I am not going to be tracking my car, well maybe a few times a year at max, and it is only a daily street car, do I need this CJM race pan?

Would the GTM pan be more practical for me?

I might go out on a limb and say that it sounds like you might not need any pan at all to be honest.

The CJM pan will put a dent in your wallet, no doubt about it. The GTM pan is practically free and I dont see any harm in having it. But the reasons I wouldnt put it on my personal car is because I dont like the big wings... I like race-car style serviceability and being able to reach my hands in everywhere I can. For a turbo car, that pan blocks off valuable hand/arm reach access to turbo system pipe couplers etc. Blocks the oil filter and oil cooler line access too. I also dont like their baffles that much, the flappers look really small and then the top is blocked off for some reason, so now oil returning from the block has to take the long way around to get to the sump area. My CJM pan does the opposite and even has vertical guides to try and influence returning oil to go directly to the sump area.

Too much oil capacity will make it take forever for oil temps to reach operating temp, which would drive me crazy because I will only baby my cars until the oil reaches full operating temp.

If a customers Z was here at my shop and they wanted oil system upgrades but didnt want to flex the cash for the CJM pan, I would use a Z1 oil pan spacer kit and a real nice oil cooler kit. The oil cooler kit will add the cooling ability you need, and the extra capacity you want without going overboard. The stock oil pan spaced down and with the oil pickup spaced down to match, will help reduce oil starvation because deepening the sump and pickup you have greatly increased the ability to keep the oil pickup submerged already... and then again the spacer adds some more displacement without going overboard. IMHO, this combo would be the best budget oil system upgrade path.

Alright, so if I did get the CJM pan, am I going overkill?

Like i said my Z will only be a DD street car and occasional tracking at most, but I am shooting for 450-500 whp on a Stage 2 SC kit and I might be using the AAM R Line oil cooler, or a similar style oil to water cooler by PWR (racing company in Australia) with a 42mm core which apparantly cools like a beast.

Would that be overkill? I do have the cash for it all, but I just don't want it wasted if I am overkilling for my application.

I dont think I would consider it overkill. I think it has somewhat to do with your own taste and preferences! Do you like the finer things? haha! Our pan is pretty nice. If you have an appreciation for that pre-installation fondle-factor, this pan takes that trophy hands-down. IMHO the function and displacement of it just right, which would say its not overkill. But if you ask me, "will my engine blow up without it?". My reply would be... probably not.

I have the CJM oil pan/sump and it's a top quality product. I also happen to love CNC machined parts. The oil also seems to cool down more quickly now when engine is stopped and it seems to assist a bit with the cooling of the oil. I also have an oil cooler and the oil does take a bit longer to warm up but it's not an issue
