Hey, if I had the option then thats the way I would go as I appreciate they do end up with a better result. I tend to look at the few people that have gone single scroll to twin scroll setup sand looked at the differences. Fair point about the EVOs but you need to factor in the boost differences from the factory, the turbo wheels themselves, the addition of MIVEC to some models, the developments in the heads and cams etc. I am no EVO nut, I leave all that techno fluff to my mate...but I think the engine and wheels the later models are running has more influence then the twin scroll. But I would take it if I could, expecially on a 6 cylinder where on paper it will have more merit then a 4 cylinder
edit...if you can find a T3 twin scroll housing that will fit onto my TD06 then will throw it on my car with the HKS manifold. Pretty sure that manifold is going on my new cheater motor. But i think if the 73HTA works well then I will end up with a 76HTA FP twin scroll on my chook cooker
