My 370z "unicorn"

Hey Rusty, about this fuel pump top hat.....I'm looking at what I'm going to do through winter months and probably this is one of the things. Does this also resolve the fuel starvation issue? While I'm in there, I'm looking at resolving that issue as well. Any recommendations?

The billet top hat solves a different issue. CJMotorsports used to sell a Road Race Fuel Pump kit. Seems like that item is no longer on his website. If I recall correctly, Charles had stated that it’s not enough sales volume to make another batch of RRP, but that was some time ago (when someone complained about the lack of available inventory). You may confirm that with Charles the owner. Also see thread below.

New season, new stuff!

This winter was pretty uneventful, as my car is....almost perfect the way it is! There was just one tiny bit where I wanted a tune. Namely, the LSD.
I have the OS Giken LSD, factory setting. There was one scenario however, that bothered me when it occured. At steep uphills like a mountain road, if there was a very sharp hairpin and I was fully on the gas, the inner wheel if lifted, would have a quick wheelspin before the LSD completely locked up. And this was just a bit slow for my taste. I wanted it to lock up quicker. So I contacted the reputable shop in Netherlands where I got the LSD, and they kindly suggested I change the preload and the sungears. So I did just that!



No specific progress pics, sorry, hands were dirty. I swapped out 4 negative spring pairs, lowering the preload from 336kg to 296kg. This should allow the pins to jam between the LSD core easier, thereby quicker engaging clutch plates. I also swapped the spur sungears for the helical ones, as apparently that should also help with the effect.
While I was working on the diff, I pulled out the breather tube that I had punctured and pressed in a new one.

At the registration, I also homologated my KW V3 coilovers. I went for a drive and it's all working well, but I haven't yet tested that specific uphill scenario to test the diff settings. In usual or slightly spirited driving on normal roads it seems the same behaviour as previously, which is good.

Alright, so just to post a couple of small updates, gonna add some pics/vids later, but for now...

...the diff tuning was a definitive success! Lowering the preload to 296kg is spot on, because now it does lockup quicker, tested on the local touge a few hours ago. Where previously it had a ~one second delay until it locked up, and which subsequently resulted in a violent oversteer if continuing to press the throttle, is now actually quicker lockup with slightly more gradual oversteer so it's much nicer to throw it around uphill hairpins.

This winter I also replaced the disc rotors, as the previous (brand new ones ) got warped, so I put new EBC Bluestuff pads again, and it works very well. I think the previous pads (EBC RP-1) might've been the reason for overheating the rotors.

On the way home, got a surprise in the rearview mirror when a newer Porsche Panamera glued on my back and then did a provocative overtake. Had a go with him on the next few corners where the Z presented itself not as a decent contender, but an absolute beast. I backed off after three corners because the Porsche driver was (I believe) either a newbie or unfamiliar with the car, having had a couple of uncontrolled sways braking for the corner and ending up it the opposite lane unwillingly. That was my cue to just let him go.

Anyhow, the season has only just begun, and so far I'm loving the current setup on the car!
