Hey guys, so my 32gtr is still giving me grief and I have absolutely no idea how to begin the trouble shooting process. I have the complete service manual and basic tools.

I am wondering If there is a gtr savvy member living around the maylands area who is interested in spending a few minutes answering questions and having a look at my car(try and get it going properly) for the price of a carton of their choice. I have read through hundreds of threads on this and other gtr sites(Canada gtr is also very good) but have not managed anything solid.

Cheers in advance guys. Here's hoping. :)

Jesse.

Well it's very similar to the problem benno2 was having, started her up and let it idle for a few minutes to warm. Cruised slowly around the block(probly 1k) then, going up a slight hill the revs started dropping even though I was still accelerating. They progressively dropped all the way down and the was almost stalling on a rough idle. Totally confused I killed the ignition not wanting to do more damage. About 4 hours later I tried starting it and it started with a regular idle but a bit low and drove back here with

What felt like slight power loss.

What do u guys think? Mass air flow? Hopefully not gasket? Is this a turbo fault?

I'm moving from a 96 v8 fairmont so this is allllll new to me.

Thanks all.

By the way I'm located right by maylands traino.

Ok, so I just pulled my top Afm out to have a looksi.. Previous master has obviously already resoldered our connections here. This is the joins, sorry they're upside down.. :P

And this is what I assume is the O2 sensor.

Very oily/dirty.

What do we think guys?

Thanks for the input. And Boss-Zilla, this is pretty much all I've done so far.

thats the hotwire of your AFM and its filthly lol that will probly be your problem (o2 sensor is in you dump pipes after the turbo), spay it with some electrical contact cleaner, DO NOT touch it with anything, next thing is to figure out where that oil came from.

That is the hot wire (sensing) element in the airflow meter, O2 sensor is in the turbo dump pipe.

And that looks like a shitload of oil on the afm, look up the cleaning DIY and see how it goes.

Got a catch can?

Edit: beat me to it horrace!

Just need to clarify, really I meant an oil/air separator.. contains baffles etc and is used to scrub oil from the air before returning it to the intake stream. Always a good thing on a boosted, legal, recirculating breather setup.

A catch can just catches any oil that may come out the breather and is a safety measure required in some racing, usually used in atmo breathing setups (and in recirc setups by people who bought cheap catch cans off ebay).

Jesse, to me it sounds like a vaccum leak and another possibility is intake manifold gasket leaking.

Have a look in the workshop manual for the vaccum layout, will show you all the hoses - make sure they are all good.

To search for leaks in intercooler piping and manifolds, grab a can of Aerostart or similar and with the engine running, spray around all the joints in the cooler piping and intake manifold - if the revs pick up you've found your leak.

Oh dear, most of the vacuum hoses look like this; (these are top and bottom turbo control solenoid hoses respectively)

I'm about to go get some aerostart to test em but I think they will all need help soon. At least if I can get it driving ok I can get it to a mech.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel

      What should I do next to hold the head on

      By MBS206 · Posted

      When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?

      Chris' Toyota Mark ii JZX110

      By Rezz · Posted

      Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.

      If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
