Nismo Z Track Impressions (3 Events)

[OptionZero]

the fuel starvation is real. Is there a kit available to add a pump somewhere? Haven’t seen anything available

i dont know what, if anything Nissan changed from Z34 to RZ34

on my Z34, i consulted CJ motoring. He previously made a surge tank solution but it waa discontinued. He said the Radium one looks pretty good, but its about $1k

CJ has more exotic solutions which involving more stuff, but they are several grand and geared for forced induction and built cars

i am staying NA so he ultimately recommended the Z1 anti starve kit which is reallly just a Hydramat, secondary pump, and some hardware and an adding an on/off switch.

thats what i went with. Switch goes on the center console, i activate it on track and leave it off on street

you can piece together the components for cheaper than z1 if u look around

AMS Performance makes an in-tank system which you can use to run single or dual pumps for more HP even or Z1 had a kit, but they don't call out comparability with the RZ34, so I would confirm before you consider that.

Otherwise avoid getting at or below half tank at all costs.

A few observations and question after 3 track days. First day stock with SRF Castrol brake fluid and Carbotech XP24 pads, pushed fairly hard and was impressed with most aspects, tires/braking/suspension, Sport+ with TC off throttle response was quite sensitive so mainly used Sport. A few times the car did not shift when I pressed the paddle on downshift and upshift but no other major issues.

2nd day added full exhaust and E30 tune, Sport+ unusable with the added power, was using 3,4,5,6 gears. In Sport turbo was still a bit unpredictable but suspension seemed fine and tires definitely got a bit worse.

3rd day I added SPL camber arms, more aggressive alignment and added 100 TW tires (F1 3R) on 18x10.5 setup. I used different tuner and the power was much more consistent with no missed shifts by the trans. I did only use 4,5,6 gears which seemed to help. On high speed trail braking the car got super twitchy so had to back off a bit in those spots. Completely cooked the Carbotech XP24 pads with SRF Castrol (multiple cracks and glazed spots) and was getting some other knocking/vibrations unable to diagnose. When everything was working well I was much more impressed with the car and can see the potential. Still not as fast as my previous Supra or RS3 though.

Any advice or parts or driving style are welcome, especially about how to keep the brakes cooler, maybe ducts or different rotors.

That’s wild to cook XP24s with SRF, definitely sounds like a cooling issue more than anything. I’d look into proper ducting first before changing pads again.

yeah it's been mentioned a few times

at above stock power levels, with 100TW tires

you need 2.5 inch ducting or better, plus 2 piece rotors (the good kind, like Paragon or Racing Brake)

or even consider swapping the stock system for something more dedicated from AP Racing

What ducting options have worked with our cars, Nismo or not? Quality two-piece rotors will help quite a bit, being lighter unsprung weight and better heat dissipation.

all i know is that the nissan solutions haven't worked, even GTR owners are always looking for more cooling

on the z34, ducting has worked, but it will always vary by diameter, tires, rotors, and driver

basically - do everything
