Really silly question, your water temp gauge ecu take off is ok right? Almost sounds like the car it's trying to warm up etc then changing it's mind. Equally check the air idle valve at the back, those connections get crappy. And have you actually done a boost leak test?

Tell him it's not actually a 300zx it's an imported one it's a fairladyz z32

It's just what they call them. http://en.m.wikipedia.org/wiki/Grey_import_vehicle Technically they are all imported, just not all of them by Nissan. Hence grey import.

Take it to a different garage it's a grey import so isn't eligible.

Should be fine then.

Exactly. Your tester should have that information. What year is your car and is it an import?

Paul is an MOT tester mate.

I don't think he's alone, when I chuck out my group email a few members get chucked back, this user cannot accept pm's or words to that effect.

Can you not? We PM sometimes over REO matters so.... Equally I never said I liked it.....lol

Say what you see Barry, say what you see.

Not a zed but this has been doing the rounds for a whole now and is next level stance fail.

That car always draws attention, that is it's focus. The engine bay is the best one around. He had different wheels a while back which were less extreme offset wise and looked better hell that's up to him. The car is about show not go quite clearly.

Well worth a read..... http://www.procharge.com.au/turbotorque/6-blog/blog/117-the-turbo-blues/

Sort of the full story sort of not. Theoretically the rear oil seal is like a splash guard, it's not a seal as such. The turbo should be able to run without the "seal" and still not smoke. Where things get complicated is pressure. With neutral pressure inside and out the turbo oil will not leak. Sadly this doesn't occur. Over pressurisation causes a higher pressure in the turbo core than in the exhaust, the oil backs up and weaps out. This can be caused by multiple conditions, excessive blow by, inefficient scavenging of the engine oil galleries or blockages in the oil return line from the turbo. Equally negative pressure can occur can occur in the exhaust due to design. This causes the oil to be sucked out the core. The presence of the cat causes an increased pressure in the exhaust system, this effectively masks the worn seal, or other symptom be it Pcv or inefficient combustion that is raising crank case pressure. Obviously it helps to not create a vacuum situation as well. The type of turbos fitted to out cars as stock have a very basic real seal, this changed in later incarnations if the t2 core. Also the jounaral bearing design uses far more oil to lubricate and effectively float the shaft. More oil in the core requiring to escape creates more issues. This is why modern BB based turbos are less prone to smoking. The thought that deleting the Pcv helps, is only half the story. A fully functional Pcv system actually lowers crank case pressure below 0 creating a negative pressure environment thereby helping contain the oil. I have some reference to explain all this better and from one of Australia's leading turbo shops. Il try to dig it up for you guys tomorrow :)

Condensation? They were discontinued on the later cars, useless guff.

Are you going to use the non turbo ones which means you don't have to change the pesky elbow section, or the full on divorced downpipes tt ones?

Exactly that, the cat merely masks the symptom.

It's actually quite similar to the series 1 wheel, also sorta reminds me of the wheel out of an 80s Pontiac.

What do you think of it now it's fitted yourself?

You takes your chances. Mine failed almost instantly after decatting :( theoretically it shouldn't make any difference common issue though.

Rare

That's fine then mate. They do tend to have a tendency to leak, they are old and very basic turbos.

Tip them thoroughly enjoy the replacement of your turbos lol.

Technically your car, its shell is a 1990, the fact the engine is from a later car is neither here nor there. The cat is part of the exhaust not the engine. I cant see why it would cause you any issues what so ever.
