Went to Sebring last weekend with NASA. Only lasted first few sessions, then blew up diff. Nismo Pro 2.0 diff ordered from Z1 and on it's way. Probably won't have it back from Z1 and installed in time for Nov at Sebring. Instead, shooting for Daytona in early Nov and Palm Beach in early Dec. Also got Z1 fuel starv kit, which will help on the sweeping right turns. I also blew up my rear axel assembly. Any suggestions on a replacement? I'm naturally aspirated at 400hp, so no need for anything extreme.

Holy ****. Oem should work perfectly fine at those levels. You have any pictures on how your diff blew or can you describe? I would email Nismo about the diff and what temperature range those clutch plates can tolerate. Dss pro level axles is always a option ( believe that the name), I would try another set of Oem before pulling the trigger on those DSSís, also I would look into a diff cooler from MaMotorsports, and a billet diff cover from soho motorsports. Will the car be ok running that crazy bank at Daytona without any oil
Issues? I heard itís highly recommended to have a dry sump you are able to keep steady oil pressure and not suck in air.

You are way overthinking it, Daytona and oil starve issues that is. Wifey ran both of our nismo 370s there all the time, itís our home track, total of six years, three for each car, never an issue, fuel starve on the other hand...thatís a huge issue.

Both cars were n/a with bolt ons, so for fi, perhaps a different issue with oil starve, btw, mikeís full on race car spec 370z never had oil starve there either iirc and he ran the **** outta that car, I believe all he had was a z1 oil pan spacer. Again, full bolt ons and n/a.

The Z1 built diff with Nismo Pro should do fine in terms of temps. Comes with their modified diff cover. Yes, I’m going with OEM axels since I’m not boosted. Used ones are super cheap vs over $2k for higher end versions made for drag strip, which I don’t need. I’ve never had oil starve issues, even on turn 17 at Sebring with R compound tires. My shop installed “idiot lights” for me so I stay on top of that. I also upgrade s the gear from 3.69 to 3.9. Hoping to see better corner exit from that.

That diff still gets crazy hot something I would consider upgrading to in the near future. Let me know how you like the 3.9, i feel like the 3.69 are perfect for Sebring. Only turns I gripe about is coming into 7 and 10 where Iím almost hitting the limiter in 4th gear.

Mike broke a rear wing there. Never heard him say anything about oil starve.

Towards the end of his time with the z before he went upscale with the gt3, he was thinking ls swap and he was TRYING to blow his motor, purposely didnít install the cjm baffled oil pan.

Still never had a problem.

The only oil pans available at that time was the AM Perf. pan. They was $1,200 then. Only 20 was sold to the public. I got the one that was on Shamu's Z. The CJM pan didn't come along until a few years ago.

I remember something about getting a chance to pick up an oil pan from him at some point, oh well maybe Iím thinking of someone else.

Either way, he still never had oil starve issues and neither have we.
