When is the next track day?

Don't know if it bothers you or not, but as soon as you remove an air bag the car is no longer street legal.

The Link G4 can read the fuel pressure sensor provided you have the spare input for it. Yep, you can T in between the rail and fuel filter for the sensor. For your wideband O2 sensor, one sensor is fine and you can install it in front of the cat. You'll need to get a bug welded on for where you want to locate it. Where the factory O2 sensors are, you can leave the factory sensors there. I wouldn't install a wideband sensor so close to the turbos.

That's bizarre, they have HKS stuff on their site =/ Did you ask GCG/Turbosmart if they have a spring of the size you require? If you're not having luck over the phone, you might have to visit your local Turbosmart dealer in person and bring the gate/spring with you to size up. People tend to be more helpful in person.

So, first thought is. Contact someone who sells HKS stuff, for example - www.carmodsaustralia.com.au They import stuff from Japan regularly and obviously can get HKS parts. They can probably help you out. Next thought is speak with a company that deals with turbo stuff as their core business. There might be some cross over with say a turbosmart wastegate spring and your HKS one - gcg.com.au comes to mind as such a company. Last resort, your going to have to learn Japanese, fluently. Fly to Japan and visit the HKS headquarters and beg for a wastegate spring. They might take pity on you and supply you with a spring.

Does anyone feel like pulling their flex sensor out to see what happens? lol

Ah ok. I was thinking that if the sensor was starved of fuel, it would not send a value to the ECU. So the ECU would just keep using the last known value. But what you are saying is, if the sensor was for example, just plugged in to the ECU with no fuel flowing through it at all, it would still function as expected and send a value to the ECU for 0% ethanol?

Is anything going to happen if the flex sensor isn't sampling fuel for a period of time? I mean the e content of the fuel is the e content, after a few minutes of driving, the mixture never changes. I could only ever see this being an issue after filling up the tank and before the current mixture was established. Is there something I'm missing?

The real challenge is, what does that car even sound like in person? Who knows. Its a video, its a very simple process to just go.... yeahh and another couple of db over the 0 to 40 hz range.... yep perfect. I don't know where you're located, but I'd advise to go to car meets with people that have the same car/engine as you. Have a listen to their setup and go from there.

I don't know if it's just me but a bunch of the photos aren't loading =/

What coil packs are you using?

All of my control arms/traction rod are stock in the rear at the moment. Does the factory setup toe out much on power?

Yep, I'm not surprised. It's good advice. Some of the really big HP drift cars run up to 10mm toe in chasing outright grip in the rear.

Do you have everything solid mounted/rose joined in the rear? My zero toe might be a lot more toe out, then your zero toe. I've still got a lot of rubber bushes to delete in the rear.

Hmm I think I really need to start running some amount of toe in. I run zero toe in the rear, because exciting, but it really doesn't help for performance lol.

I think I'm going to need a detailed breakdown of your suspension components, setup and alignment lol. I can't even put down 300kw on the street in 2nd. Say I'm cruising around 1500 rpm, then floor it in 2nd, around 5500ish rpm it will break loose. I wonder how much of that comes down to the shape of the power delivery from the journal bearing turbo. Maybe if I went with the ball bearing centre, it would have had a more gentle power delivery.... I dunno.

100% agree with this. A proper diff would be at the top of my list of priority mods.

CRS is about 50% more expensive then NS2R in identical sizes, check out the links I put up. Yeah I've been looking for sur4g for a while now, can never find any place that has them in stock. Also been looking for Valino and Zeknova tyres, again no one has stock for what I want. I would run a square setup if I could get the same size to fit the front. Can't see that ever happening without cutting up the front guards and fitting flares, but I'm really not keen to do that. Yep. I'll check out that tyre shop, see how we go with pricing.

It's a weekender + track stuff. It varies, but I'd say I do about 10,000KM a year. I'm priced out of CRS completely. I got a quote for CRS when I was picking up the NS2R... CRS in size 275/35/17.... $435 Can't get NS2R in that same size, but I paid $265 for 255/40/17 Here is a good apple / apple comparison. https://sleekaspares.com.au/product/255-40r17-nankang-ns2r-semi-slick-tyre-120-180tw/ https://sleekaspares.com.au/product/25540r17-nankang-cr-s-competition-semi-slick-200tw/ I don't know how long the CRS would last on the street, even though they are "200 tw" they are a faster tyre then the NS2R, so I would expect they would have an even shorter life expectancy. 15,000km sounds pretty good to me. The more I think about it, the more I think that's where I'd want to be for my street tyres. I think it's bothering me that the tyres won't even last the year.

Did you use these? https://au.gktech.com/solid-subframe-bushes

I've got 2 sets of wheels, both my track and street rears came up for replacement at the same time. I popped 120 treadwear NS2R on the track set and have been using them on the street. So now I'm in an awkward spot, I really like them on the street, even in the wet but that rate at which they are wearing, I'll probably only get about 7500km of street use out of them. So now I'm torn, do I just accept that wear rate or should I pop something like some RS4's on the street set, or maybe try the 180 treadwear version of the NS2R.... What wear rate are you happy to accept for street tyres?

Mako makes this - https://makomotorsport.com.au/collections/nissan/products/nissan-skyline-r34-mfd-mount-2 I bet they could make this - and this To have a baby. That would get you half of the way there.

More inspiration stuff- https://www.skylife4ever.com/2011/02/nissan-skyline-r34-mfd-display-swap.html

You could take inspiration from something like this - https://zada-tech.com/products/multi-gauges/nissan-skyline-gtr-r32-r33-r34-multi-function-gauge-display Then model it up for your Link MXS in something like Fusion 360 and get it 3D printed.
