So I've been waiting/planning years for the day I finally get a Gt2860RS, almost ordered one last week. Then Garrett goes and Releases the GTX 2863R. Now what do I do? I keep telling myself I need to draw a line, at some point its just to much, but damn...

Personally I think there are alot better options for your dollar and you can also save money in the process. The entire GT line is rebadged technology from 20+ years ago with the exception of the ball bearings. The GT2860RS is nothing more then an T3 super 60 compressor combined to a T28 turbine with ball bearings. That is it.

What is your goals? Whats the purpose of the build? For me I would not buy a ball bearing turbo unless I was planning on running insane levels of boost and if the car was a dedicated track piece. Yes they are nice to have but for the cost the minute added performance is not worth it.

Why don't you try?
But what's the setup, because they say it will flow 20% more.

The turbo himself is looking hot!

I think anything short of a GT2871R is kinda silly as far as GT28 turbos go.
I got one of these in the mail a few weeks ago. Should go well paired with 10.5:1 compression using it for autocross.

EFR-6258 looks even better. The match bot program is pretty interesting, 1/2 my time is at 5500' and the other 1/2 is up at 9500'. I built the motor and trans for 300 hp. Wonder how many psi I could run on pump gas? If I could run 20-23psi the EFR map looked pretty good at both altitudes.

efr's back ordered until the end of Feb. I guess the Indy Izod series switched to the EFR's and have priority on production. I did order a 6258 though.

here is the map

Update:

The EFR that was supposed to be shipped feb 28th, was pushed back to late july. I cancelled the order, Go-Autoworks is hooking me up with a s252 BatMoWheel...

I haven't seen any dyno graphs of one on a D either, but I'm hoping it should be close to a gt2871.

here is a s252 graph, Bullseye didn't have one for the batmowheel, but it should be a little more efficient. The generic statement was a regular s252 is good for 450hp, and with the batmowheel its good for 550hp.



and just to make things easier.

The batmowheel inducer turbine is soo crazy looking. The compressor housing is pretty interesting too, i see go-autoworks updates on facebook all the time. Makes me rethink using the brand new garrett turbo i purchased for my build, its so basic compared to some of this new stuff coming out.
