Help Understand GTT Boost Setup

[GTSBoy]

I have always resisted the urge to go silly.

8" wide wheels and street friendly spring rates? Check.

(Let's not talk about the steadily increasing spread of spherical joints across my suspension!!)

Stock turbo, run at 12 psi? Check. Lasted for~?10 years before it died. Highflow put on rather than seizing the opportunity to go G45.

You don't need 300 rwkW, let alone the more massive numbers that seem to be essential these days, to have a car that is already way too powerful and fast for a streeter. ~250rwkW is fine. I've never exceeded 200, although I will sneak up above it if and when I manage to get my finger out and do what needs to be done to use the highflow's capacity.

You don't need $10k worth of CF bits glued onto the outside. You don't need razor sharp ankle cutting front splitters. You don't need the car to be 2" off the ground. You don't need flawless paint, mirror finished wheels, brand new indicator lenses, etc etc. All these things just make the car impractical and will cause you pain when they get damaged, which is inevitable for a street car.

A few nice additions are good. Good seats are good. A nice stereo is good. A/C is good! (46° on the road yesterday and my A/C is degassed again. Was moderately traumatic driving home!)

The main reason I stick with a mildly modified old Skyline is that I have had it for >25 years, the mods are the rolling result of 25 years of things dying and being upgraded opportunistically, coupled with a few "just 'coz" ones. And I hate almost all modern cars. If I was a young buck starting out now.... I wouldn't bother. Cars have a few years left where there is any possibility of interest or fun. Thereafter there will be no such thing allowed or possible. Any time, money and effort spent now on a project would just be a waste.

I genuinely bought this car because I never got to enjoy it when I got my first GTT in 2015. 
I’m a simple man, give me a skyline that goes reliably from A to B and I will be happy. I mainly like driving it when the roads are quiet so you can relax. 
Nothing wrong with a few mods here and there but it wouldn’t be instagram worthy 😂

Big list. Get security asap I reckon.

Currently when the car is parked at home, I have the added security of a galah sleeping next to it 😂😂

But yeah, I want the viper system soon and saving up for it. Probably the next one after nistune

The west where I live is swarming with birds, not wrong they are bloody loud.

In the meantime, do a DIY killswitch - $5 worth of things from jaycar, easy as too. The west is copping it with car theft lately, especially the big shopping centres.
