I haven't seen anyone online preparing to dyno except boostfreak27 here... I'm not just talking sr20's either, I mean, this is the ONLY one I've found being tested on any engine. The closest I've gotten is gtx3071 to gt3071 dynos and then extrapolating to how a gtx2867 and gt2871 would compare.
On a side note, have any of you guys seen this
here?
ATP is offering a gt28xx upgrade for to a gtx2867 for only 300 bucks!
Used gt2871's go for what, $800-900? So let's say I sold my gt2871 to buy a gtx2867 new with exhaust housing which costs around $1400 for group buys, $1600 for individuals so that would run me anywhere from $500-800 to upgrade vs $300 to have ATP modify it?
Depending on what they actually do to make it into a gtx2867, this could be a great value. I would not mind paying $300 bucks to have what theoretically should be more responsive and run an extra 2-4psi just as efficiently as my gt2871. Is anyone familiar with ATP's upgrade? Would I really be winding up with exactly a gtx2867 or is it more like an approximation? I think I might be calling them soon...
