If you're looking to kick your build into high gear, the GTW3684R (also known as the GTW6262R) 62mm ball bearing turbo might just be what you need. This little beast has a potential flow of up to 750HP, which is pretty impressive for a turbo of this size. It features a .82 A/R and a T3 undivided inlet, plus a welded GT 3" V-band outlet turbine housing that makes installation a breeze.
Now, let’s talk specifics. The compressor wheel has a 62.3mm inducer and an 84.4mm exducer, with a trim of 54. On the turbine side, you’re looking at a 71.0mm inducer and a 61.9mm exducer with a trim of 76. The compressor housing is built on a T04S frame, sporting a 4" inlet and a 2.5" outlet, and it has a built-in, machined anti-surge feature that really helps with efficiency. It’s a solid choice for those who want performance without breaking the bank.
Just a heads-up, though—this isn’t a direct drop-in replacement for the small frame Garrett GT or GTX series turbos. The GTW series is bulkier, so you’ll need to plan for that. Also, the oil return fittings are different, so if you're swapping from a GT or GTX, make sure you have the right components on hand.
Speaking of components, if you’re piecing everything together, you’ll need a couple of things. For coolant options, grab two 14mm coolant fittings and lines. The oil feed is a -4 AN with a built-in restrictor (check out product code ATP-OIL-021). You’ll also need the oil drain flange (ATP-FLA-042) and gasket (ATP-GSK-027), plus some 8mm x 1.25 bolts (MIA-FST-034). For the turbine housing, you’ll want a T3 inlet flange (ATP-FLS-038) and gasket (GRT-GSK-005), along with a GT 3" V-band flange (ATP-FLS-246) and clamp (CLC-CLA-048).
Overall, the GTW3684R is a solid choice for anyone looking to boost their ride's performance without emptying their wallet. It's got the specs and the build quality you need to take your project to the next level.
