Turbos - information

[Poodle]

Been meaning to start a thread like this for a while, thinking it'll be useful for reference. I want us to compile a basic list of information on turbos to make it easier to spec one suitable for the intended application. Between us we should be able to create a brief guide to explain the various aspects of turbo specs - a/r, trim, housing, compressor inducer and exducer, etc - and a decent list of different turbos with their relevant figures.

What I need from you guys is information on the turbos you have lying around, please post as replies to this thread. Give as many details as you can about the specs, what car it comes from and its intended application.

If you’ve got anything else you’re willing to contribute I’d appreciate it if you could get in contact, cheers!


USEFUL LINKS

Most of the information I’ve found can be summarised in these links. Bear in mind a lot of the information is tailored to petrol engines, I am trying to find relevant figures for diesel engines to make it more applicable.

I believe a good figure for AFR is 18:1, BSFC is 0.35 and for VE is 88%

Garrett GT2056S, don't go over 30psi





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.

Model: 751578-2
CHRA: 433289-234

Cooling: Oil

Inducer: 41.5 mm
Exducer: 56.0 mm

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.
