My rego runs out next saturday so I needed to fix all the cars problems which were:

1. Replace cracked rear rotor.

2. Fix exhaust leak - diagnosed as turbo to manifold gasket cos I could actually see the missing part.

3. Clean up after my dodgy catch can.

4. Also borrowed a GTR bov to test fit to see if my stocker is leaking and causing my gradual boost drop. I know not for rego but still needs to be done.

1. was pretty easy once I took the handbrake off. Doh!

3. Easy.

2. Was very proud of myself because I was able to replace the gasket without removing the turbo or exhaust, just undid the exhaust mount nearest the front.

4. Decided to go temporarily atmo because the GTR bov has a larger diameter outlet than the stocker. Confused myself when I installed it and realised I had an open pipe where the plumb back used to go but I used 4 thicknesses of heavyish plastic held on with a hose clamp to fix that.

Started her up and the bloody exhaust leak was still there!! WTF!! And, the car wouldn't idle properly.

I put my hand over the bov outlet and that cures the idling problem. What's going on there? Is it leaking? Is it supposed to?

I went for a drive and the exhaust leak seems to be less but it's confusing and annoying. I noticed that the face of the turbo where it mounts on to the manifold doesn't seem to be perfectly flat. Does this happen often? Can I get it machined flat?

So either the warping is too bad to fix with a new gasket, there was always another leak, or I just didn't tighten it up enough (which I don't think cos I did it pretty tight).

Arrgh!

      Could you modify this duct so instead it pushes the extra air through the radiator too and not down and out? For temps, I know it's not the greatest idea, but as a bit of a last resort, you could use a very intermittent misting spray onto the front of the coolers/rad. You don't want to be soaking them such that water is dripping off, but a small most on/off so that the water evaporates. That point of it constantly evaporating, rather than being soaked in water, will pull a LOT of heat out of the cooler. I'm literally thinking just the little mist sprayers for a garden from Bunnings. Being in a low humidity climate it will help even more! The other trick if you want to be ghetto is some shade cloth hung in the opening, and keep it wet. Pretty much now it's acting like an evap cooler on a house, but cooling the air you need to use to cool the radiator...   On a topic to think about too though, when air enters through the bumper, is it all nicely ducted from the edges of that opening back at a nice angle, or is it like most cars, and the edge of the opening just stops, and suddenly it's wayyy wider behind that? If it does the later, get it shrouded out at nice angles. When that opening changes too rapidly, it can actually cause a high pressure zone between the front bar and radiator, and limit air flow into that area, which means less air for cooling, as it effectively stalls the air, AND adds to drag...

      WGNC34 Rear springs

      By zoomzoom · Posted

      It doesn't look like there's a lot of options out there these days, and what's out there is performance oriented aftermarket stuff (with the GTR markup) I wonder if there are other cars with similar springs, after all its just a matter of length, diameter and stiffness. Alternatively, I did see coil spacers. Probably not the best option, but could be serviceable too.
