Hey guys

I am getting tierd of everyone calling the turbo

GT28R

that is only referring to FRAME nomenclature.

what is the real name?

IE 2871

2860

2540

etc?

this is what it actually is

GT2560R

you can find it here

http://www.atpturbo.com/Merchant2/me...egory_Code=GRT

FYI I can get you this turbo with a t25 Core Exchange but NON-BALL BEARING For the low low price of 600 bucks.

PS The 60 Trim compressor wheel the GT2560R (GT28R) usually comes with is not as efficent as the Super 60 T3 Compressor wheel. I can retro fit your core to use this to make more peak output woithout sacrificing spool or power band and also raises peak efficenty a tad and makes hp possiblities into the 340 range, plows the dp into the ground with a custom turbine wheel.
