Garrett GT2056 turbo

The TD04-13t-4 might work OK. Used on a 2.5litre 143hp IDI (BMW 525TDS), so should support a 160-170hp IDI if it can give you enough PR to get a Franken to that kind of power levels. Spool would be slower than on the BMW, but should be reasonable especially if gov.modded

yeah that turbo is the best one of the bunch certainly.  the best thing would be to make a compound setup, maybe a ko3 off a tdi compounded with one of these:

surging could be an issue

You forgot something again

You forgot something again

Dang... anyone have a compressor map for that?

[RabbitJockey]

i see what i did wrong there

[RabbitJockey]

does anyone know much about surge tanks?  where you add volume say twice the volume of the engine to the intake in order to prevent surge.  this was something they did on turbo charged v twin motor cycles because the intake valve is shut for such a long time between the 2 cylinders that the air really had no where to go.

[RabbitJockey]

the more i think of it, i do not think this will help to prevent the surge that we fight with a low flow, low rev, low displacement engine, the surge tank would only really help in the v twin situation between intake strokes of the 2 engines.

It appears that the k26-2 will spool the quickest. Alcaid, what do you think about the lag on the td04h-13t?

[vanagonturbo]

A stupid though, but a thought still... what about using a BOV? Something that can be calibrated to exhaust extra pressure when the differential is too high but not exhaust pressure when things are going as they should.. what do you guys think about that?

Sounds like a great idea.

[vanagonturbo]

I was thinking an EBC to operate the BOV. Not sure if the EBC would take a w terminal signal feed though. that would be the easy idea. If not, a circuit could be fairly easily designed..

[RabbitJockey]

kinda wanted to revive this and discuss some of the new turbos again... i think gt2056 is still a good option for a 1.6td assuming there is good flow in the head and intake manifold surging issues should be minimal

Any news on the GT2056?
