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.

    • The 32 still sits untouched with the broken gearbox. So a little off topic but not worth having a whole new thread. The daily starlet has gotten back on the road after 9 months. Suspected blown HeadGasket at a track day resulted in a bit of scope creep rebuild. The motor got a full tear down, pressure testing, machined for MLS HG, ARP head bolts, new bearings, all new seals etc also noticed some fatigue on the stock exhaust manifold so obviously the answer was a steam pipe manifold and highflow turbo. The exhaust was also looking tired with some rust holes. So I got a slightly over kill system made up consisting of Vibrant resonator and muffler with a highflow cat. The new highflow turbo had a larger inlet so instead of adapting the old intake got a case of the might as wells and had a nicer alloy intake made After the run in was finished i bought a (probably considered retro/vintage) EBC becasue "might as well"
    • Pretty stout result. How much boost? Anything left in it?
    • Just dropped the car off at MX5 Mania to install the intake plenum and give it a little retune  My impatience hates the waiting game 
    • SAMSONAS      Just saying      U know and we know U wanna     Just a matter of time....
    • This is kind of what I expected given the use case. I took my liners out for track days too.... It makes me consider just getting a diffuser and not bothering with the arch liners themselves. For the most part I would like to avoid water/mud/jank splashing up from under the car onto the bottom of the engine, lines, wiring, etc etc. (but brake ducts are cool too). Especially given this post on SAU here: Where it's implied you have to cut them because the actual tub is different? Which is pretty damn worrying because that is where the liners rub in a GTR with wider wheels... I definitely won't want to pay $2000 for plastic then cut them up. It also means said wider wheels rub on the tub in a GTT? FML. That said, I have found some evidence someone ran a 295/30/18 without scrubbing these liners. (and by extension.. the tub).
