V6 3.3 200hp with 8.9:1 (VG33 Nissan Frontier if you're wondering)


I have (most importantly, a welder), long tube headers, no cats and full 2.5 back

Planning on a single turbo rear mount just after my custom non restrictive Y pipe (just where the bed starts), with 2.5 pipe back to the intake. No intercooler.

Planning on a scavenge pump return to oil fill cap.

I have ignition and fueling mostly figured out, wideband and boost gauge already in, so onto my question:

I know it's stupid but Im going with the brand EMUSA for turbo, WG, and BOV

This is a truck so I don't need the top end, I want to boost as low as possible and I rarely take her above 5.5k RPM. Big HP is not my concern and I don't want to boost above 15psi.

Here are my choices, which turbo would you get in my situation?

(Keep in mind rear mount will have lower exhaust velocity and heat yet I want to spool at low rpms)

T3/t4 hybrid .63 AR
0.50 cold side 49 trim
0.58 hot side 61 trim

Gt3076
.70 cold side
.64 hot side

Gt2860
.60 cold side
.69 hot side

Thanks


PS. Yes I know these trucks came with a supercharged model but I want to do a turbo setup
