This thread along with Mafia's and Lithiums have given me a great deal more knowledge on turbo choice (mind you alot of disco's essays still go over my head) so cheers guys.
I'm hoping that we can get some decent results of a real GT3071R .63 A/R on an RB25 soon, as I'm looking at this turbo as a real option for a mainly street driven, stock bottom end RB25. However if the guestimates of only 250-260 are correct I cant see the benefit of choosing this turbo over for example a GCG hiflow with either RB25 or VG30 housing. The cost would be much greater for the garrett when you sort out the lines, fittings, custom dump and intake. So my question is, if 250-260 is what this the Garrett is limited to then why bother?
Now, does anyone think that the GT3071R .6 could pull 280rwkw on pump fuel, stock manifolds, possibly cams? Or would the .8 be needed? Discuss
Finally does anyone in vic have a GT3071R equiped RB25, and feel like showing me what its like on the road? Would be much appreciated.
