So, I've been pouring through the Honeywell Garrett product catalog, and there's almost no mention of the GT17xx series turbos, other than an aftermarket kit for older 1.9/2.0L VW engines that use the GT1749V turbo. I haven't sat down and plugged the numbers into a calculator to sanity check this (and I've lost the software I used when I was sizing turbocharging my old Sentra SE-R Spec-V), but first pass suggests that the GTX2860R GEN II might be a candidate for an upgrade from stock. Also considering the viability of the GT2560R, for a little more mild of a bump over stock. Anybody got insight on what it takes to adapt these options to the stock manifolds, or has already run the math on the sizing to fit?
Most of the twin-scroll housings I've found so far are for GT30 and larger turbos, which are almost certainly bigger than I'd want to put on a daily driver setup for a twin-turbo engine of this this displacement. Though, thus far I really haven't looked outside of Garrett's offerings either.
