I'd do it all again in a heart beat. Well, not all, I'd make some different choices in which mods. But I'd definitely still spend all the money.

So you're saying don't let him do a track day in a car I own? Granted, I've only ever had successful track days in other people's cars, and a 100% kill rate in taking my own cars to the track...

You miss spelled bearings...

Maybe you need to go borrow one of Pete's cars? He doesn't seem worried about break GTRs

It's got a problem Prank... It looks like both washer spray caps have fallen off this car... 😛

The title of Engineer is not protected. However different states have different rules about what an Engineer requires to operate. Engineering for a motor vehicle modification is very different to engineering for a bridge, electronics, etc, including what that engineer needs as certifications. In Canberra, "Engineer" is the loosest category with basically nothing stopping you calling yourself and engineer and designing a bridge or building. From what I've reviewed, QLD has the strictest requirements through RPEIQ.

Well, in 2007 he must have been charging about $1800 an hour. He only looked at the car for 5 minutes. And another 4 to write the report wrong, and another minute to correct it. Mind you, this was for a car that was: Stock engine, fmic (hole in drivers guard), all alloy intake and custom air box, 3 inch turbo back exhaust, lowered, and a set of 17" Advans (255/40/17 rear and 235/45/17 front). It was nothing crazy. The blue slipper wanted the "hole in the guard" engineered. But that was because he got the shits that I wouldn't "relocate the battery from the boot, back to the factory position in the engine bay"... In an R33 GTST... Also for emissions, E85, and don't go wild on timing. It's amazing how the closer you get ignition timing towards max torque, the last couple of degrees really throw NOx counts right up. And for the huge increase in emissions, it's only a small increase in torque.

He'll be looking down and swearing about "the damn apprentice" for trying to convince Duncan to use percussive maintenance... 😛

Geez, engineers fees have definitely gone up. Mine back 2007 cost me all of $300. Mind you, I had to go back to him a few times to get him to write the correct things on the report after he'd inspected it. Things like wrong exhaust size, wrong wheel sizes, etc etc.

Come on guys, they're just trying to sell their project car to scrape together a house deposit in the Western Suburbs of Sydney...

Sounds like the solenoid might be cactus, if the solenoid trigger wire was still attached (and it was just the main power to the starter itself remove). Just to provoke Neil haunting me for the rest of my life... Have you tried tapping it with a hammer while someone switches the key to start? This might work for the fuel pump too... 😛

The consult isn't even OBD1. It's a Nissan Consult. Proprietary. Re read everything I've said. I specifically say, put down the laptop/tablet. Understand, and review the issue first. Logging voltages is the same as logging the converted value. Things like O2 that you say to log, is unusable for this, whether it be the voltage, or the value the ECU thinks. The fact you don't know how to diagnose without looking at the computer, is exactly what I've said multiple times is the issue for why techs these days can't diagnose the fun issues with cars.

I agree, don't go trusting those trims. As I said, first step is to put the logger away, and do the basics in diagnosis. I spend plenty of time with data loggers. I also spend plenty of time teaching "technicians" why they need to stop using their data loggers, and learn real diagnostics. The amount of data logs I play with would probably blow most people away. I don't just use it to diagnose. I log raw CAN data too, as a nice chunk of my job is reverse engineering what automotive manufacturers are doing.

Silly question, as I bet you've checked already, but the motor turns over by hand yes? I suspect Neil has a spare starter, though if not, I believe I have a spare R33 (or two) starter.

Ahhh! My silly brain was thinking Nissan started selling them straight away, but they waited w or three years didn't they? Maybe Duncan should build an R35 race car over the V37... There's a cheap yellow one on car sales Duncan, would only need your splash of purple added...

How do our rules work in Aus with importing one, since they were sold locally here?

Stock O2 sensors are narrowband. They're useless once you're away from stoich. IE, useless for what you're trying to do. 10:1 will read the same as 14:1 from the stock O2 sensors. That is, they'll read rich. The same level of rich.

You should totally get a Brumby, and then come pick up the Subaru Liberty GTB I have here. EJ25 Turbo, 6 speed manual from the sti (just no dccd), and the good rear diff. Drop all that into a Brumby and go have fun!

What mods are done to the car? By driving in traffic, does it die while moving, say at 50kmh? Or its when you're sitting idling it wants to die, or when idling and you go to accelerate? When you're idling, how long is it normally idling for time wise before it starts to miss and sputter?

I was more thinking so it doesn't flop around as much rather than for rotating it. Once you have the balance right, it should rotate well enough, depending on how much resistance there is on the pivot. I think you said the pivot point was on a bearing though didn't you?

Sag as in the windows start to slowly open themselves, or they're just slow to go up/down with engine off?

It looks like it needs a big worm gear drive on it to control the rotating, not a few sloppy pins!

As Duncan said, first there was OBD, which few cars used, then came OBD2. Now an interesting point, OBD2 isn't even for what you want to do. OBD2 is for emissions testing. There is some sensor data on OBD2, but it's up to the manufacturer what they're putting on it. Most scan tools operate on UDS, which like OBD2 is a standard built on-top of CAN. UDS specifies how to structure a message, what very limited things mean such as "read memory address" but it does not specify what is stored in which memory address, that is all up to the manufacturer. You either a scan tool compatible with that vehicle, or to know how to reverse engineer all the data, which can take a VERY long time and a lot of vehicles to get it right. Oh and then the manufacturer does a firmware update and changes what's where... Ask me how I know that as fact Oh, and by the time you've got the scan tool that supports all the manufacturers stuff, well, you're back at "But a consult cable and the Nissan software" The main difference being most manufacturers software these days works with the same hardware readers, as the readers are built to support J2534 which is another standard for how the PC communicates with the tool to make it do specific things on the car...

Diagnosing with and without is mostly the same. You need to know, as Duncan asked, and what conditions. Car hot, cold, idling, driving, if while driving what rpms, is when you're varying, or is it when held constant. From there it's understanding what can be causing it. Starting with pretending all of the sensors are correct. Which means if it's going rich, why would it be thinking more air is going in than it is, and under what conditions. So things like if only when under boost, it could be be a loose intake piping joint. It's just understanding the system, and understanding when/how the problem occurs, and then if it's only occuring in specific scenarios, what can be causing it. ECU specifically, if it's aftermarket, it'll have software you can use, for the Skylines on factory ECU, there is Nissan Consult you can use. Most ECUs have a way to get data from them.

Stock O2 are basically useless beyond anything at stoich. Any misfire will also be seen as lean. The stock O2 also read a collective exhaust gas volume, not each cylinder. Sputtering and missing means not each cycle is firing, and some are. Which means even if rich, as shit, on cylinders as they miss, they'll read lean, but the cylinders that did fire will read rich, and combined, well, they can read anything from rich to lean. Start with the basics before even going looking at sensor values. Edit: I say the above, and that's coming from the guy with a few thousand dollars worth of scan tools sitting right beside me right now that I use frequently for my job.
