reads90 Posted September 27, 2006 Share Posted September 27, 2006 Hi Tony do you have any prices or bonuses of fitting this. Ie what amount of more power do you get out of doing this. sorry if this has already been asked chher Ali Quote Link to comment Share on other sites More sharing options...
GBMUD Posted September 27, 2006 Share Posted September 27, 2006 So, how is the nozzle controlled? Is it some internal mechanism or is it via the external diaphram as pictured? Does such a turbo still need a wastegate to limit boost? Chris Quote Link to comment Share on other sites More sharing options...
Diesel_90 Posted September 27, 2006 Share Posted September 27, 2006 apparantly a 300 manifold will fit a 200 so you could do this mod to a 200tdi B) Quote Link to comment Share on other sites More sharing options...

Bear in mind, though, that these turbos oush out 1.2 bar on overboost as standard so you want to make sure the headgasket is in good condition before doing anything. As far as figures go, you could get 1000bhp but it wouldn't last very long! I thin something like 170 bhp and 320lb/ft would be about right with a reasonable fuel tweek.

So what actually controls the nozzle? Is there a waste gate - and could whatever controls boost pressure be adjusted to cap maximum boost at, for example, 1 bar? My head gasket is new... ish.

will_warne Posted September 27, 2006 Share Posted September 27, 2006 Chris, honestly, I'm not sure about what controls the turbo. I think it doesn't have a wastegate simpley because the non VGT version of the 2.8 is called the HS 2.8l WG (standing for wastegate).

SOA 93 Posted September 27, 2006 Share Posted September 27, 2006 Hi Tony do you have any prices or bonuses of fitting this. Ie what amount of more power do you get out of doing this. £1354.00+vat from Allards http://www.allardturbosport.co.uk/pages/la...r_discovery.asp been available for quite a while I believe, I've no doubt it could be done cheaper.

Ex Member Posted September 27, 2006 Share Posted September 27, 2006 It is a veriable geometry inlet turbine. There are adjustable vanes in the inlet of the turbine and boost is controlled by adjusting the position of the vanes. There is no wastegate. Here is some information Do a search for VNT turbos and you can learn all by your lonesome. Quote Link to comment Share on other sites More sharing options...

will_warne Posted September 28, 2006 Share Posted September 28, 2006 I wonder how one of these turbo's would work glued onto a Td5? B) Apparently they tried it in the factory and the results were awesome! Quote Link to comment Share on other sites More sharing options...
rusty_wingnut Posted May 25, 2009 Share Posted May 25, 2009 does anybody know what was done with regard to ht eoil feed? The TGV has a pump on the back of the alternator and a feed back into the sump. Quote Link to comment Share on other sites More sharing options...
Bush65 Posted May 26, 2009 Share Posted May 26, 2009 does anybody know what was done with regard to ht eoil feed? The TGV has a pump on the back of the alternator and a feed back into the sump. The oil feed on the 2.8TGV receives its supply from the oil gallery in the engine block. The line divides, with one branch supplying lube to the turbo and the other branch supplies the vacuum pump (on the rear of the alternator).

rusty_wingnut Posted June 2, 2009 Share Posted June 2, 2009 I finished it last night and test drove it at around 2am! Very very pleased! I made an adaptor to mount the TGV oil drain pipe to a 300tdi block. And for the feed pi[pe I used a 300tdi pipe turned through 180degrees at the block. I have used silicone hoses and steel pipe to link the inlet to the air filter with an aluminium bend over the exhaust to avoid the exhaust possibly burning a silicone hose. TGV downpipe for the exhaust linking into a standard 90 mid box and a straight through rear section. Initial impressions show much more low down power and it seems to pick up a lot faster. the Exhaust had given me better pick up before the turbo but now I reckon it will pull a disco transfer case happily. You find yourself dropping cogs a lot less as the power is there to accelerate through the gear you're in. very worth while, and I have some pictures of the adapto required for the oil drain and my complete install.

Turbocharger Posted June 2, 2009 Share Posted June 2, 2009 Good stuff, and considerably faster project than my own VGT lash-up. I'm particularly interested in the control diaphragm - my impression of the turbo I have is that the spring pressure needs to be quite weak (or the diaphragm needs to be quite large). Any chance of some close-ups of the pressure diaphragm? Quote Link to comment Share on other sites More sharing options...
rusty_wingnut Posted June 2, 2009 Share Posted June 2, 2009 I will endeavour to do this upon my return frommanchester to see the mighty Oasis. PM me your address and I will pop that bypass valve i promised a while back in the post tomorrow. Quote Link to comment Share on other sites More sharing options...
Turbocharger Posted June 2, 2009 Share Posted June 2, 2009 Oh aye, many thank yous. Wouldn't want to interrupt a gig schedule with some early-90s has-beens I guess my key question is how easily the vane actuator moves - I can't move mine by hand but I guess yours might move quite easily?

Bush65 Posted June 5, 2009 Share Posted June 5, 2009 Good stuff, and considerably faster project than my own VGT lash-up. I'm particularly interested in the control diaphragm - my impression of the turbo I have is that the spring pressure needs to be quite weak (or the diaphragm needs to be quite large). Any chance of some close-ups of the pressure diaphragm? It is difficult to judge with the actuator in place. I used screwdriver to lever the linkage down, against the spring. My best guess is it takes something like 4 kg force applied at the actuator. Based on the outside diameter of the canister, I would think the effective diameter of the diaphragm is about 45 mm. From the stamped figures on top of the actuator, it is made by Wahler. The other markings are "2/2" and "S 16/2". I don't know what these indicate and could not find much during a quick search.
