More seriously though..

Garrett GT2056S CHRA number 714652 (ext 5005, 5006)

Fitted to the 2.5DCi Vauxhall Movano/Vivaro, Renault Trafic/Master engine code G9U730 125bhp model
Circa 2004-2006, be careful as some were fitted with K03's and/or Mitsubishi branded turbos
Newer vans moved to a GT17

The Garrett GT2056 turbocharger is the biggest turbo in the GT20 family. With a 55 Trim compressor this turbo will give you 260 HP. Recommended for engines in the range 1400cc - 2000cc this is the turbo you can find under the bonet of many different cars. Also this is a popular turbo to turbocharge motorcycles with. Will work well for anyone looking for 140 - 260 HP and have good spoolup also.

Realistically on a 9mm pumped 1.9 XUD you're looking at reliably up to 170bhp at 26psi.

Consider this option if you want fast spool combined with respectable power, without the added issue of controlling VNT's. Suited to less-gov shimmed engines than a TD04 as the power band is much lower, wouldn't recommend revving to 6krpm.

Currently running 24psi on the estate, 20psi by 2250rpm, peak boost at 2750rpm. Cruising speeds 4psi at 60mph, 7psi at 70mph.

DO NOT overspeed or dewastegate these as they have a habit of snapping shafts, my last one went at about 34psi. Keep it sensible, it's more fragile than the seemingly bombproof T25 and TD04, however spools FAR quicker.
