If your after one thats for sale - go to the For Sale section.

Failing that - there are what, a dozen traders on SAU? Surely one of them can be contacted :)

Failing that (last resort) - www.yellowpages.com.au if you cant find one from a wrecker there - there aint any in the country...

Thanks.

yep this area has been placed on the no go zone with rotor bur flap sanding disk only.

Also the bottom of the exhaust port if its matched to the manifold gasket is also quite thin.

was also surprised to see a water jacket running through the web that seperates the two exhaust ports for the same cylinder, would have thought that to be solid

hey yall here is my monumental f$%^ up

you will see the areas in red which you have to take care not to remove to much alloy.

I will post the pic with the water jacket running through the webbing in the exhaust port tomorrow just to draw out the agony lol

way too far there...you can see by the shape of the port that what you have done would actually hinder the gas flow. ie.too much of a right angled corner. GTR heads flow pretty well out of the box and for a circuit car id concentrate more on the inlet for light porting and knife edging and only give the exhaust a clean up and polish. For a given volume of gas to flow through an orifice (port) the larger the cross-section the less the pressure it will be and a "softer" hit in the manifold and on the turbine wheel. The larger port will in most applications actually decrease the response of the turbocharger.

    • Well, in the same way that you can't tell any SUV from any manufacturer in any size category from any other one, "sports" coupes now all look identical. Stand back and squint your eyes and the Supra and the 400Z and the GR/BRZ things all look the same. I was just thinking last night, when sitting behind a Subaru CrossTrek, that I have no idea what it is, how it differs from an XV, or a Forester, or an Outback, or anything else Subaru offer, and I couldn't tell if it was supposed to be small, medium or large. I contrasted that to the good old days, where a HQ Kingswood had familial similarities to an LJ Torana, but there is no way that you could confuse them, and how a bit later, the HX Kinger and the concurrent Torana and the Gemini all had familial similarities, but you still could not confuse them. Ditto the ugly Fords and Chryslers of the era. But now, a RAV4 looks like a Kluger, looks like a Yaris/Cross/whatever they're calling those stupid f**king things, looks like every other Toyota that's not a Camry/Corolla sedan.
    • The Prelude doesn't look that bad without all that lens distortion in those pics. Makes it look disproportionate when it isn't. Actually I kind of liked it at the Osaka Auto Messe earlier this year. 
    • Pour in the highest octane, non-ethanol fuel you can get and see if the readout changes. If it's dead bang on 11% then I would question the sensor. Another quick test, just take it out and run normal (in an american accent) gas-o-line through it and see if the sampled ethanol or lack of changes.   United E85 here in the land of drop bears does vary a bit, I've had as high as E87 (could be water in their tanks too, who knows)
    • Yep. And if you ever do, you'll just have to deal with it then.
    • E10 is pretty tightly regulated in percentage. Too much and engines can't adapt. Every incentive is against them to have too little ethanol though. The more ethanol the higher the octane.
