Ok well i spend an inordinate amount of time scouring these here forums for information GTScoT, it's trying to eliminate conflicting advice which is the hardest part, usually between the people who believe in spending as much money as it takes (usually GT-R owners and those who have a lot of disposable income), and those who are looking to get the bang for their buck, whilst not neccessarily needing to have the perfect combination at parts with all other factors disregarded.
Of course the HKS option is always going to be the easiest way out but I like to explore all avenues before committing down one particular path. I also think that this thread would be benefical to others who are looking at going for a Garrett turbo.
TBQH turbocharger design ins and outs is hard for me to wrap my head around, apart from the basic methods of fitting and their operation. I choose not to dwell on this particular aspect of my car. If i were truly not 'really into' my chosen hobby of car modification, then I would just go straight out and buy a HPIAB or Hypergear "3076", or even a high flow would I not. Some of you people need to understand that not everyone has the same level of comprehension of physics concepts, and that turbo jargon can even be misleading (ie the old Garrett naming system, HKS calling GT28 turbines GT25 etc).
The reason for me originally posting in this thread is due to the fact that my interest was piqued by what seemed like a cheaper version of the 3076 which would bolt directly onto existing fittings etc. When it was pointed out to me that this would result in a mistmatched turbo and really a waste of a good cartridge, I evaluated my options (and yes I've read the dyno thread).
I've asked before about the 3071 and previously been told that they are too small of a turbo to be worth buying for an RB25DET. I have since found out that in the HKS form they are good for up to 280rwkw which suits my need for decent response (to get the porcine gts-4 up and moving), and reasonable power figures (which I believe the high flows lack in over 250rwkw). Also given the cost of say a GCG high flow you may as well go the whole hog and buy an entirely new turbo with more efficient housings.
