Yes we have had fitted to 5 developement cars for the last 12 month.
Results are superb with final power output depending on the modifications already done to the car.
attahed is a picture of ne of the dyno runs we made on the first developement turbos, we have laterd a few things since to make the car hold torque longer.
of coruse this is with a remap also and notjust the turbo.
We are now selling this turbo for 670gbp+shipping costs.
This unit is exchange for your standard salvagable td5 turbo or it carries a 250gbp surcharge.

what turbo is that?

well i am still realy into it and looking at every option, but i now have a new way of geting her to go, i am able to get my hands on a turbo of a tdv6, the only diff is that a tdv6 is 2.7L an td5 is 2.5, so ovusly it has been made to work with 2.7L, but since its vv and all id to it take the electronic control off it and put a macnical actualtor on it, will it still run fine, with the .2 less of a L and been vv it wil work at alot lower revs, well in theroy,;)
but i can allso get hold of 1J turbos easy to, and since there desyned for 2.5L it could b the way to go

The turbo on the v6 is a Garrett GT2256V (712541-0001/2/3E).
TD5 has a Garrett GT2052 (452239-0003/4/5E).
So GT22... turbine is a little larger than GT20... but the variable geometry will most likely still make it effectively smaller at low revs, and ...
The GT..56. compressor is larger than the GT..52. compressor. But you want it to be an upgrade don't you ;)
I used a GT2256V on a 300Tdi and they are 2.5 litre, so I see no problem with the turbo size on a TD5. What problems the extra boost pressure will create with the engine management is outside my experience.
This should be better plan than twins, but I wanted to see how you were going to divide 5 cylinders by 2 turbos - seems I will never find out :D
Sequential turbos..... A big one for top end and a little one for quick response, both in line.Quote:

so 1J turbos it is,
looking at the turbos theres a fear bit of room to play with in the fender, all i need to do is mod the oil lines and get coolent from the heater hoses, a adaption plate is been made so i can try and use the origanal manifold, at the same time im going to be doing the web cuts on the manifold,
and a 3" is going from the dump pipe all the way back and give the butifull sound of the 1J turbos, i love the sound of them,:D:D,, cant wate:D:D
hopefully soon il have a bigger intercooler and have the new hoses,
boost box and im trying to find some one who makes a dump valve for the td5s eny idears??
oh and of couse tombies ecu chip to top it off,:cool:
I reckon a single VNT will effectively do the same job as a twin setup. The diffuser vanes angle to spin the impeller up quickly and then re angle to limit boost levels impeller speed. This lets you use a larger turbo but have no loss of low end boost or response yet have a much higher flowing turbo.
The whole thing takes up a lot less space than a twin setup and if done carefully will almost look factory.
Here's my VNT conversion. http://www.aulro.com/afvb/projects-t...o-upgrade.html
It's got about 15,000Ks on it now and hasn't missed a beat. It's got no lag and makes plenty of power. Fuel economy is great too.
It's great fun to develop stuff and bolt on a lot of whiz bang parts but you have to be careful. You could end up spending a pile of cash on something that doesn't make that much improvement at the cost of reliability.
