Picked her up today at the end of Phase 1.
Trans, diffs and transfer case fluids (fluids and gaskets from Z1)
New oem rear stay and coupe rear sway bar with new hardware. Can definitely tell the difference with the rear sway.
Tack welded Stillen exhaust sections and did the final tighten down of the clamps.
Installed painted front grill and rear spoiler
Replaced the vertical weather strip between the front and rear doors(OEM from Amayama)

A few pics, but will take more from under the car when I get the chance.

Next up I need to install my matching painted emblems on the trunk and Megan Racing front tower brace,

Then I’ve started gathering parts for Z1 big brake kit. Got the sport dust shields cheap from Amayama and ordered the red calipers from Z1 along with red paint to paint over the Z1 logos where I plan to put on black Nissan decals instead. Man, red Nissan branded calipers are off the charts expensive! Way better to go this Z1 optionIMO. I want to do wheel hubs at the same time I do this and probably 15mm spacers for a one and done.

What I’ve learned from this adventure so far and what I would do differently: 1) I should not have been so fast to re-do my oem wheels - the car really needs 19” rims to handle up to its potential. Would have been better to have held off and tried to find a set of G37 coupe wheels as a kicking off point, however, that would have almost definitely warranted lowering the car which is not in the cards right now. So, a push. 2) That being said, the car really needs a stiffer spring and shock set up again to reach its potential. I’d like to eventually do a 1” drop with springs and shocks (need to research what is the tried and true option here).

Do people use RWD oem sport springs for a modest drop? And what shocks for an AWD?

Pics of my interior (60k mile time capsule!). Barely even a crease on the drivers seat. Without an interior in this shape, I would not have invested what I have in the car. Mechanical and body is one thing, but there’s really no way to bring an interior back to original shape if it is compromised, I truly do not think anyone ever sat in the passenger or rear seats!

Trying to figure out why this isn't a DIY.
Just scheduled this for next week at the dealer. He said they use BG (smells great) and apparently it is a foam that fills up the entire hvac system (ie, he said the cabin filter has to come out or it woukd be soaked).

I can’t recommend this enough if you’ve never done it and if you have, good to do every few years to keep her smelling fresh.

Not sure how much different it is but you can buy
Amazon Amazon

Take your filter out and the evaporator is in the center of the car in the dashboard. So you'll need to fish that probe in there

You can save your time and $$$ and do it yourself. Just take out the cabin air filter and spray a can of disinfectant through the blower motor with it running. Did mine about 3 years ago and no odors since. Just roll down the windows and air it out for about 10 to 15 minutes

The cost is about 100$ and all I can say is that the last time I did this I was shocked at what a difference it made. Very much exceeded any expectations that I had. Maybe I could do as well myself, but given my prior experience I think I will let the dealer do this one for me,


BG Frigi-Clean and Frigi-Fresh are products designed to clean and deodorize a vehicle's HVAC system.Frigi-Clean removes debris and contaminants from the evaporator, while Frigi-Fresh eliminates odors.These products are used as part of the BG Climate Control System Service.

Elaboration:
  • BG Frigi-Clean:
    This product is specifically formulated to clean the vehicle's A/C evaporator. It foams up and fills the evaporator core, removing debris like dirt, dust, mold, and bacteria. This process improves airflow, restores A/C efficiency, and eliminates foul odors.
  • BG Frigi-Fresh:
    This product is designed to deodorize and disinfect the HVAC system. It eliminates odors, kills mold, mildew, and fungi, and leaves the vehicle interior smelling fresh. It also helps to prevent the growth of harmful microorganisms in the moist environment of the evaporator.
  • BG Climate Control Service:
    This service offered by BG involves using both Frigi-Clean and Frigi-Fresh to thoroughly clean and deodorize the vehicle's A/C system. It can also include the use of a high-performance oil, BG Frigi-Quiet, to ensure quieter and cooler compressor operation.

Actually, this does look very easy!

60$ on Amazon for both products! Damn, now I’m going to just do this myself…

Key was knowing what product they used and now that I know it is BG I can definitely do this DYI.

Thanks for motivating me team 😁

For reference, Ive still got OEM suspension (RWD sport) with coupe 19s (factory size tires too). A modest drop would look cool, but I think the factory ride height looks fine too (biased of course)

I’m mainly holding out on upgrading shocks and springs until something breaks, which might take a while at my pace

Your coupe wheels look absolutely perfect! Whole car looks great! Drop is also perfect.

This is my previous 2011 ISF which I think shares a lot of resemblance with a well done G sedan. Love them both. The ISF edges out the G in many ways, but honestly the G is not that far off and I actually prefer the interior and front end of the G over the ISF.

Amayama

Has anybody here used Amayama for parts out of Japan?
My bottom weatherstripping on all four doors is all stretched out (they are referred to Seals). These parts are discontinued in Canada at least. Put the part numbers in Google and came up with Amayama. The price seems Very reasonable, which is a little worrying. :-)

I guess I will have to see if they ship and then what the quality is like.

Appreciate the kind words.

And the ISF was absolutely part of my inspiration for modding my car. In a “if Nissan/Infiniti offered a sportier trim, it’d prob be something like an F-model Lexus” sort of way. If the ISF came with a stick-shift, it’d very likely be what I’d be driving today. Somehow I’m still hung up on three pedals.

Believe I might be in your neck of the woods, maybe we can coordinate a trip to cars and coffee sometime. In the meantime, it’s nice to see all the progress you’re making here. Sharing is caring as they say!
