Garret Releasing Their Competition Tr30r Turbochargers .

[discopotato03]

Garrett are saying that they will release the TR30R turbochargers for sale to anyone with the bucks . I would not expect everyone to rush out and buy a turbo with inconel and magnesium housings as well as the CNC machined from billet compressor wheels . Very deep into ouch territory .

All the vulture at Planet Potato cares about is that we may at last be able to get our sticky hands on that yummy 60mm NS111 turbine that TR30R's have in either 76 or 73 trims . This is the missing link in the currently laggy GT30XXR saga and together with the billet wheels (cast for general use) could make for turbos with little lag and strong mid range torque .

Ever noticed how you mostly see power graphs of turbo engines where the Hp numbers are higher than the torque figures in foot pounds ? The good news is that in the recent past any way WRC power figures seemed to float around 300+ horsepower and 460+ ft pounds of torque . Wouldn't that be a hoot in your Skyline ?

so what kind of money?

$5k? or more?

Don't they run restrictors in the WRC cars which is probably why hp is down realtive to the torque. I think they also run a round inlet on the turbine housing so throw in the cost of a new manifold as well.

^^^ clearly its more of a tweakers option. Whats a 1200 d00ler manifold compared to the potential promises of one of these wheels / turbos setups.

id love an WRC style turbo

Hi all , I don't have a price figure but I suspect it would be quite a few thousand .

They are based around the GT25 BB centre section so cartridge wise I don't think it would be real difficult to use the turbine/bearing cartridge and compressor wheel in the production bearing housing . Once you do this current GT30 turbine housings fit the hot side and the adapter ring/backplate/compressor housing fit the cold side . Production housings (both) would need to be profiled to suit the different wheels but thats not a biggie - for Garrett or the aftermarket .

Competition turbos like these often have V band fasteners because it makes them quick to remove at service intervals during an event . The high tech materials used make them light and also high temp resistant .

The rally people I speak to reckon its common practise to dump a bucket of water over these things to be able to get at them after hard use .

Most of us roadies don't need this kind of durability so the production turbos use more affordable materials .

Restrictors , yes and thats much of the reason that a lot of development went into these turbos . Its a big ask to make a lot of torque from a 2L four that runs out of puff at ~ 5200-5500 because of the air restrictor . The anti lags systems do help initially but that creates an extremely harsh environment for the turbo to cope with heat wise .

Cheers A .
