Yeah, I think it's much safer just to spend the extra $300 and get a non VNT GT2056..Quote:

what about this? it's the smaller 52, but it's got the .46 housing..

GT2056 with the 0.46 A/R turbine is good for a clean and safe 150kw on a 2.5tdi.
That's 31psi boost at 4000rpm, approx 90cc/1000 shots of diesel and an intercooler that can shed about 16kw of heat.
This is a complete match, turbine, compressor and wastegate. EGT around 740C (preturbo), A/F ratio 18:1. Turbine drive pressure around 38psi.
At 2000rpm it'll give you 18psi boost (limited by surge on the compressor) which is ~330Nm. At this point your turbine drive pressure will be a shade under your boost, your A/F ratio is almost 21:1 which keeps EGT here to well under 700C.
Next step up is the Garrett GT2259 (hino version) with the 0.47 A/R turbine. More power from that one, but you'll lose some bottom end torque.
Holset HE211 could be an option. But I haven't mapped that one out for anything yet. Information is scarce.
Can a 300Tdi hold 30psi with tightened head bolts?Quote:
