Bahahaha, bloody hell Greg. You've got bent and broken things, but instead, you're replacing perfectly good items. This story keeps getting more gregged! Also, I'd 100% replace that reo if I were in your shoes, unless you panel beater is REALLY good. Even if you put another GTT one on there. Just because you've done so much nice body work lately, I'd say repair the body work fully If it were more drift car spec, I'd be all "Hit it with a hammer and send it!"

Yep, agree with all of the above added on too. I just love the age old "what boost were you running?" Question without getting any other surrounding data. IE, may have ran 20psi, and lived for 12 years, but it was an 80 year old granma driving it to Bingo once a week and never took it over 2500rpm.

The "ideal/formula" that used to be touted was death of the turbo is going to be caused by a combination of 3 things. Heat Speed of turbo (boost level you're pushing) Time Basically, you can get away with high heat and high boost for short periods. But start doing long hard pulls, or circuit driving etc, and now you've increased time as well which will shred things. From memory when Adrian was drag racing he was running 17psi, on a stock turbo, and running insane speeds. But he also had other additives helping in the setup too. Some people have success at 14psi for a while, while others due to pushing the cars hard for long periods opt down to lower temps. But also, generate a lot of heat (let's say bad tune), for a long time, and you'll be okay, until you try to spin that little guy up slightly. It's the one advantage of dumping a lot of fuel in, you'll be reducing EGT a bit and helping with the heat portion of the above 3 areas. And these days, stock turbos are that old that there's the possibility of just outright failures due to material age. I'm not shocked that even when used in factory spec that a stock turbo fails when 30 years old. It's a worn out "precision" "balanced" performance item, that's likely no longer precise, or well balanced

In a few years from now, you'll regret that. It'll eat away at you, knowing the truth of the ugly hiding beneath the beautiful exterior... 😛

Some of the stuff the PDR guys in the states pull is amazing too. Instead of drilling a hole. They crank some insane tension into it. I actually DIY built a pulling bar myself that I used to pull the Subarus front end out with. About an hour's work, a bit of 30mm *3mm shs, and a piece of 5mm thick plate. Worked great! But I vote replace it with a GTR rad support. And not going to lie, I'll laugh if a GTR rad support doesn't fit a GTt...

That's a write off for sure... Part out? 😛 I kid. It looks like the rad support has a minor minor bend in it too where the rep support sits near. Could just be the photos (and me not wearing my glasses right now). Worst case is you can buy a new radiator support, have it swapped over, and leave the car in paint jail for 12 to 18 months while you build the motor to handle twin turbos or a Harrop SC...

LandCruiser used to get a fluid flush every 12 to 18 months. Only because it was about that often the electric motor on the master for brake assist kept dieing and needing to come off.

Give the fluid a really good flush, then go do the same track again. Report back too please

How good is it though when you can run the AC without the engine running to cool the car off before you get in it during summer? God I'll miss a bunch of the EV features when it leaves on Monday

I hear you were headed for a track day yesterday... Thread clearly needs updates

RBF660 doesn't meet DOT5.1 as it is too thick. DOT5.1 has a very low viscosity requirement compared to DOT3 or 4. (Dot5.1 must be half as "thick" as DOT4) It would also be a big indicator for anyone using that fluid in extremely cold weather to possibly look to swap for something in the DOT5.1 range.

Or it's a photo from his last track day 😛

Races cars don't care for VIN either...

Ha ha ha, mine loves to spend, all on the dogs (they're our kids, and her spending would likely rival that of some people raising children!) the only benefit is, her spending is tax deductible as she runs a business in the dog industry 😛 The above all means she can spend race car budget quicker than I can. 😛 That and a lot of the things I want are very expensive, and I can be a bit "you want how much for that?!" And at other times overly impulsive. Or I start the w days of research, get to day 1.5 and get really annoyed that no one will advertise actual specifics and it's just marketting BS and I go "well, now I don't want anything to do with that now!" Also I hate paying lots of money for something I can make from $50 in materials. Then I get the shits halfway through making things and wonder why others who just buy parts have more fun... 😛

I totally couldn't do the whole kids taking up my life thing! 😮 I find it bad enough doing 45 hours in 4 days, and then fitting normal adulting life into the other 3 with no kids! As for my mates race cars, they're AMG C63 setup for production racing. The original is what has just been stripped and a brand new shell built. The original is then going away to have some panels straightened, then it will be put back together again. Then there's a third that will shortly head off to have a roll cage put in, then build it up too. And potentially a fourth to be built too... Oh, and he has two Renault Clio D class production cars, ha ha. And when he's not racing them in the Australians and QLD production championships, he's been racing one of Chaz Mostert's Lamborghini's in GT4. They just won GT4 at the 12 hour in the Lambo. We're pushing to finish the new AMG as it has its first round (and potentially its first shakedown/outing) in under w weeks for Round one of QPC, and that round is really the shakedown to make sure it's all good for the Bathurst 6 hour, which I'll be at too. Ha ha ha Working on my project is different to his, I slowly tinker and work ways to make things happen on a shoe string budget. Hes in a good position that he has a massive workshop full of parts and tools, ha ha. He also looks after me. When his air compressor died, he just needed it working, so bought himself a new one and gave the old to me. Sand blaster unit too, and a 20t pressing. And pretty much all the shelving in my shed too as he upgraded all of his (the stuff he gave me is the expensive black Bunnings heavy duty stuff)! I enjoy working on his stuff. No decision paralysis, and anything that's needed parts wise is just there. Plus, then I get to be hands on at the track in real racing, not just club day stuff.

Ha ha ha! I know those feels mate I've finally got the garage cleared enough that next weekend I'll do some actual work on my car (hopefully). Unfortunately garage isn't usable after 10am at the moment That said, I've done a lot of work this weekend on helping finalise a friend's Production Race car. Full started Christmas Eve. We're down to about 8 tasks on the list, including "get a wheel alignment". Sometimes it's just easier working on someone else's car or project than our own stuff 😛

How's your first born doing? 😛 As for now what? Time to forget about it for 12 to 18 months while your go down a totally unrelated rabbit hole... 😛

Fuse taps are perfectly fine to use, especially when you're adding stuff for your own car, and so long as you're being smart about it. IE, don't throw a 30amp circuit, onto a circuit that is only a small circuit. It's best to add a small circuit, to one that is already quite large. Oh, and make sure you're not going to blow the fuses that are further upstream too! I dislike their use in other applications, such as alarms, telematics/tracking devices etc, as it's far too easy for someone to unplug them and render a system useless. Those sorts of devices I go for wiring in quite secretively.

Went looking at mine, reading off the tyre, presumably these are 1st week of 2003. Still hold air (I haven't had to pump them up in over 12 months!) I couldn't quickly find the date on the front tyres, they were fitted around 2008 to the rims, so probably not quite as old, but they have a lot more dry rot cracks in them. Still hold air.

I am now intrigued to go check the dates on the tyres on my Skyline... We need a game of who has the oldest tyre still holding a car up, and successfully holding air (for longer than a 2 weeks I feel is successful air holding). I feel your tyres may be beating mine

I think it's bound to happen, you finally get it all perfect, and bam, something will happen. I took a while to get a Commodore rear quarter repaired where a P Plater clipped it. Two days after getting it back, Sarah wiped it out on a concrete pillar in an underground car park... This is why I take forever to repair them, it stretches how long until it gets bent again... 😛

And this, is just ONE major issue for closed loop control, particularly using PID. One such issue that is created right here, is integrator wind up. But you know GTSBoy, "it's just a simple PID controller"...

First up, I wouldn't use PID straight up for boost control. There's also other control techniques that can be implemented. And as I said, and you keep missing the point. It's not the ONE thing, it's the wrapping it up together with everything else in the one system that starts to unravel the problem. It's why there are people who can work in a certain field as a generalist, IE a IT person, and then there are specialists. IE, an SQL database specialist. Sure the IT person can build and run a database, and it'll work, however theyll likely never be as good as a specialist. So, as said, it's not as simple as you're thinking. And yes, there's a limit to the number of everything's in MCUs, and they run out far to freaking fast when you're designing a complex system, which means you have to make compromises. Add to that, you'll have a limited team working on it, so fixing / tweaking some features means some features are a higher priority than others. Add to that, someone might fix a problem around a certain unrelated feature, and that change due to other complexities in the system design, can now cause a new, unforseen bug in something else. The whole thing is, as said, sometimes split systems can work as good, and if not better. Plus when there's no need to spend $4k on an all in one solution, to meet the needs of a $200 system, maybe don't just spout off things others have said / you've read. There's a lot of misinformation on the internet, including in translated service manuals, and data sheets. Going and doing, so that you know, is better than stating something you read. Stating something that has been read, is about as useful as an engineering graduate, as all they know is what they've read. And trust me, nearly every engineering graduate is useless in the real world. And add to that, if you don't know this stuff, and just have an opinion, maybe accept what people with experience are telling you as information, and don't keep reciting the exact same thing over and over in response.

As I said, there's trade offs to jamming EVERYTHING in. Timing, resources etc, being the huge ones. Calling out the factory ECU has nothing to do with it, as it doesn't do any form of fancy boost control. It's all open loop boost control. You mention the Haltech Nexus, that's effectively two separate devices jammed into one box. What you quote about it, is proof for that. So now you've lost flexibility as a product too... A product designed to do one thing really well, will always beat other products doing multiple things. Also, I wouldn't knock COTS stuff, you'd be surprised how many things are using it, that you're probably totally in love with As for the SpaceX comment that we're working directly with them, it's about the type of stuff we're doing. We're doing design work, and breaking world firsts. If you can't understand that I have real world hands on experience, including in very modern tech, and actually understand this stuff, then to avoid useless debates where you just won't accept fact and experience, from here on, it seems you'd be be happy I (and possibly anyone with knowledge really) not reply to your questions, or input, no matter how much help you could be given to help you, or let you learn. It seems you're happy reading your data sheets, factory service manuals, and only want people to reinforce your thoughts and points of view.

Holy hell! That is absolutely stunning! Great work!!!
