Mr Valmonty's 350z project. Learning through doing


Recommended Posts

Hey all. 

Thought I'd start a build thread for my 350z

 

Purchased my 350z last year. Photos attached are from the day of purchase

Slightly worn in places - but completely stock car

GT edition with track Rays wheel option

 

The aim is to DIY as much as possible, which forces me to tinker and improve my mechanical knowledge

My long-term goal (looking 3-4 years ahead) is to turbo the car myself and learn to mess with the ECU

 

 

I've previously heavily modified a mini R53, so this is a nice upward progression

I'm also a bit of a data nut, so I'll be dropping facts and figures into the area below as I find them.

I'd love to make a comprehensive reference for enthusiasts

The whole front bumper and boonet were covered in stone chips

Grabbed a kuro black dabber pen (paint code: KH3) and filled all the visible defects.

 

Before and after:

Added some mean-lookin' ABS headlight eyelids

 

Stuck on temporarily for now, as I'm not sure whether they'd get through an MOT

If they pass an MOT, I'll later aim to fuse them with the edge of my bonnet

Looking good mate, always nice to see the info and data logs, however don’t think I’ve ever known anyone to use dot 3 for these especially as dot 4 all round is better due to higher boiling point which is definitely needed on these as they get so hot. 
 

Keep the good work coming 😊

Thanks

 

This is partly why I wanted to make a full dataseta. Half of the specs I had to find on forum threads and not always sure how reliable things are

 

I've updated the top

On a side-note, I made myself a 350z wallpaper for my PC

Looks great!

Take everything with a pinch of salt and do your own research always best method haha! there’s a plethora of knowledge here on the forum!

Removed the front numberplate and badge

Filled, sanded to 5000-grit and re-sprayed

 

During the process, I noticed quite a lot of existing damage on the lower edge of the bumper. So I'll probably look to change the entire thing to a Nismo V3 with professional paint-job in the near future

 

But here we are for now...

Dentist had been telling me to use floss for quite a while

Finally discovered how I am supposed to use it

 

Removed the rear lettering and badge. Replaced with a black 'Z' badge

I'll admit I bodged it, but I wanted superSUPERSUPER-bright cool-white LEDs over the numberplate

 

I will formalise a proper housing for them once the 3D printer is up and running.

 

Function over form and all that. The picture doesn't do it justice

This was by far my favourite modification so far

 

Japspeed K4 twin-exit exhaust, combined with a rear bumper tuck so that the pipes are showing from behind. Glad to take out some of these rusty pipes from underneath. Three self-tapping bolts for the bumper tuck 

 

What's more, the exhaust seems very responsive to foot control. Keeping the throttle light, it's barely louder than stock and will definitely be girlfriend-friendly. But ramp up the revs and it gets very exciting.
