Johnnydrama’s N/A Nismo 370Z Build Thread

[johnnydrama]

Finished up installations underneath the car:

Z1 fully upgraded differential w/ Street Pro w/ 4.09 gears
Z1 Diff brace
Z1 performance sway bars w/ sway links
Fast Intentions 10” non-resonated Sport exhaust
Coated all of my Soul Function chassis braces Red to match.

Pictures don’t do it justice just how good and clean it looks under the car. Somewhat sad to take it off the Jack stands but can’t wait to drive it.

First some brake upgrades, some under the hood goodies and maintenance. Then headed for dyno runs/tune 4/18 at Dynosty!

Got the car tuned today again down at Dynosty in Louisville. Picked up a few more ponies, 358WHP. And I know I’m biased because it’s mine, but the exhaust setup sounds absolutely wicked.

Got it thanks, I uploaded/posted on mobile and it looked correct. Just updated/corrected my OP on my laptop.

Went full Carbon under the hood w/ full titanium hardware kits, nuts, and bolts.

I’ve had the pedals for awhile, just added the floor mat heel guard. Love when I open the door how inviting this cockpit is!

Checked another visit off the to-do list last week, and was able to get the car weighed. In addition to the power, braking, and handling upgrades I was always curious what the car weighed with the weight savings modifications that I've made. Off the top of my head, here are some of the main weight reduction mods:

-Lightweight Battery w/ 3D printed tray
-LTH
-FI Exhaust
-Full Carbon Fiber Engine bay w/ Titanium bolts
-Lightweight Flywheel
-Lightweight Pulley
-Lightweight 2-piece rotors
-Spare Tire/Tools Removed
-Racings seats/mounts
-Bash Bar

The car filled with all fluids weighed an even 3,100 lbs. on the dot. Originally w/ the build I always wanted 400hp/3,000lbs while maintaining OEM+ performance/aesthetics. I read in a 000 Porsche magazine article years ago from a Porsche engineer that 400hp/3,000lb is perfect for at street car (can't remember if that was strictly for mid/rear engine or not). Given my car is ~420hp and 3,100 lbs. that's really close to those figures and I'm quite happy. Cutting another 100 lbs. out would be difficult and excessive at this point and I really have no intentions of pursuing that mark. I will likely just imagine that without all fluids and dry weight the car is pretty close to that 3,000 lb. mark.

How are you liking that Z1 diff + Gear combo? I have yet to update my rear Diff mainly because I can't decide if I want a clutch type or not.

I like it a lot, definitely a noticeable upgrade. The 4.09s really helps with the lack of torque that this car has. I never had a problem with the viscous LSD on the street but the Z1 is noticeably better at getting the power down when throttling out of corners. I always drive with TCS off. One improvement I didn’t expect/think much about before install was the improved throttle off deceleration into a corner. Only negative that I could share at this point as there is more noise from the diff on decel, a slight whine. If you never drive the car prior I doubt anyone would even notice.

I've used this battery in another car before. It definitely needed recharging if it sat for a while.

Yea I've never had a problem with it. Typically the car doesn't sit for more than a week or two at a time. Even during the winter I will start it up and let it get to operating temp. Probably should grab a battery tender, just never have.
