Hi guys, I've been looking into T3 turbine housings for the GT30 series turbos (specifically the GTX3067) which will fit to the standard manifold. Response has been high on my priorities, so the 0.63 IWG housing was originally considered, although was always a bit concerned about boost control. Always thought it would be nice to find a turbine housing which sat between the 0.63 AR and 0.82 AR housings commonly used. I was pleasantly surprised to have stumbled upon a couple of options which might do the trick. First one is the Cosworth 3-bolt outlet IWG housing (first pic below): http://www.atpturbo.com/mm5/merchant.mvc?Screen=PROD&Store_Code=tp&Product_Code=ATP-HSG-075&Category_Code=GTH Seems to have a really decent sized wastegate port too: http://www.turbobricks.org/forums/showthread.php?t=103756 This housing is stated as having a 0.72 A/R, so sits nicely between the two "normal" housings. Seems to me like it could be a good balance between response, top end and also boost control. Downside is I would have to go with a less common outlet flange. Second option, is this housing which has an external wastegate flange (second pic below): http://www.atpturbo.com/mm5/merchant.mvc?Screen=PROD&Store_Code=tp&Product_Code=ATP-HSG-043&Category_Code=GTH Quoted from ATP website: "Special turbine housing, T25-EWG-44, T25 inlet flanged, GT28 style 5-bolt outlet. External gated (44mm flanged), flows like a full T3. Available for GT28RS/71R/76R, full size 60mm GT3071R/GT3076R/GT3082R turbine wheel and Stage III (76 trim) turbine wheel. Allows full T3 flow but on T25 flanged manifold. Only available in .72 A/R. .72 A/R is built to GT30 geometry so this A/R is comparable to one that is right in between a .63 and .82 A/R GT30R housing." Note that although it's listed as T25 it can be optioned with T3 inlet. Also interesting here is that this can be gotten in form which fits the cropped GT3071-WG turbo, so may be a decent option to get HKS 2835 Pro S type performance at half the cost? Overall second option is less appealing to me because it's another step away from stock looking, plus more expensive due to cost of wastegate and extra plumbing of dump. Wondering if anyone has had any experience with either of these (especially Cosworth one)? Or even just thoughts on how these might perform would be very welcome? Hoping the collective intelligence of SAU might shine some light on this. Cheers, Mark.

Hi all, I was working on the car recently and noticed a curious discolouration of my front rotors. It's only on the inside edge of the disc on both sides of the car. Otherwise the discs look fine, even wear and no signs of cracks. I have DBA T3 4000 Series slotted rotors all around with the standard R34 GTT Sumitomo calipers, Remsa 650C pads, HEL braided lines and Dixcel high temp fluid. The rotors have about 15,000 km and two Sandown track days on them. Has anyone else seen this, is it anything to worry about? Could the inside of the disc be running hotter because of the backing plates and less airflow? Cheers
