Bushpig110 Posted July 14, 2016 Share Posted July 14, 2016 Hi I have been asked by a customer to fit a 'Big Turbo' , His words I'm going to fit a full sized intercooler and silicone hoses and will need to do something with the injector pump fuelling The Question is has anyone got any sensible advice as what to fit and where to buy it from . Cheers Jon Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted July 14, 2016 Share Posted July 14, 2016 Not sure there is much to be gained by adding a bigger one, the stock turbo is pretty good, and has way more performance margin in it before it runs out of steam/efficiency, or the engine runs out of pistons/big ends. The only thing a bigger turbo will add is lag Quote Link to comment Share on other sites More sharing options...

Ex Member Posted July 14, 2016 Share Posted July 14, 2016 Just turn up the stock one and match the fueling. Quote Link to comment Share on other sites More sharing options...
Bushpig110 Posted July 14, 2016 Author Share Posted July 14, 2016 But the customer is always right He want a Bigger Turbo so I must find a way Quote Link to comment Share on other sites More sharing options...
qwakers Posted July 14, 2016 Share Posted July 14, 2016 so go stick a big ass turbo on it, and then when the customer says its undrivable, just say i told you so. orrr, turn up the fueling and boost and give the turbo a cosmetic refurb. they'll never know the difference lol Quote Link to comment Share on other sites More sharing options...
Bushpig110 Posted July 14, 2016 Author Share Posted July 14, 2016 I have thought of that route but would I be able to sleep at night knowing I've charged for it , probably non Quote Link to comment Share on other sites More sharing options...
Ex Member Posted July 14, 2016 Share Posted July 14, 2016 Buy a VNT then. It will produce a better and more driveable car with much less lag and more power (if you adjust the fueling properly). It will cost a lot. Everyone will be happy. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted July 14, 2016 Share Posted July 14, 2016 Yep and you can get the work from knocking out the big ends in a year or so time 1 Quote Link to comment Share on other sites More sharing options...
need4speed Posted July 15, 2016 Share Posted July 15, 2016 Surely with the money a new vnt would cost with setting up etc your customer would be better off selling and purchasing a sorted td5. It would sound nicer as well... Quote Link to comment Share on other sites More sharing options...
Bushpig110 Posted July 16, 2016 Author Share Posted July 16, 2016 The customer has had TD5 and gone back to 300 tdi , everyone has a different reason to own the Land Rover they want and for what ever reason he doesn't like the newer stuff, his wife has a 2015 2.2 tdci and he paid for it but doesn't drive it very often ,he just doesn't like the way the engine responses . So I think it's VNT , intercooler and set the pump up Quote Link to comment Share on other sites More sharing options...
Gazzar Posted July 16, 2016 Share Posted July 16, 2016 If bigger isn't better, fit two, Bi turbo tdi! Quote Link to comment Share on other sites More sharing options...
hangover Posted July 16, 2016 Share Posted July 16, 2016 Surely with the money a new vnt would cost with setting up etc your customer would be better off selling and purchasing a sorted td5. It would sound nicer as well... VNT's arent that expensive and if you can get a 200tdi manifold it can be a bolt in job. Plenty of wrecking yard turbo's that would fit and are cheap.

Gazzar Posted July 16, 2016 Share Posted July 16, 2016 How do vnt turbos work? I get the variable geometry, but what exactly causes the turbo fanto move to any particular angle Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted July 16, 2016 Share Posted July 16, 2016 they don't, vnt is variable nozzle turbo so its some vanes located in the housing that moves, not on the turbine itself Quote Link to comment Share on other sites More sharing options...
Bushpig110 Posted July 17, 2016 Author Share Posted July 17, 2016 I a have 200 tdi manifold on the shelf, but was thinking of the 300 tdi direct replacement that Turbo Technics do in the UK Quote Link to comment Share on other sites More sharing options...
Chris Davies Posted July 17, 2016 Share Posted July 17, 2016 So which VNT turbo's bolt straight to the 200tdi manifold and what vehicles do you find them on? Quote Link to comment Share on other sites More sharing options...
Gazzar Posted July 17, 2016 Share Posted July 17, 2016 they don't, vnt is variable nozzle turbo so its some vanes located in the housing that moves, not on the turbine itself Okay, but what mechanism causes them to alter? Throttle position? Boost/Manifold Air pressure? Am curious as have a defender tdi200 in the series. Quote Link to comment Share on other sites More sharing options...
Tim2809 Posted July 17, 2016 Share Posted July 17, 2016 Some are boost pressure controlled so when no boost the vanes open to give as much boost as possible and close to reduce boost as it builds up. Others are vacuum operated and some are stepper motor controlled Quote Link to comment Share on other sites More sharing options...

Come on, Hangover, what's the answer to Chris's question? I'm sure a lot of members would like to know what VNTs bolt to a 200Tdi manifold.

hangover Posted August 3, 2016 Share Posted August 3, 2016 Various VAG turbos which i believe i read here on the very forum , anything with a T2/T25 flange and of the right size should work. Some will take more adaption than others but nothing a lump of machine steel cant fix. Quote Link to comment Share on other sites More sharing options...
hangover Posted September 17, 2016 Share Posted September 17, 2016 I found that an Iveco 3.0ltr uses a GT2260V and just happens to bolt directly onto a 200tdi manifold if you drill out the threaded holes to 8mm, turbo sits a little higher than stock but shouldnt cause any issues. I bought this just for the exhaust housing but may build up a 2nd turbo. Quote Link to comment Share on other sites More sharing options...
Arjan Posted September 17, 2016 Share Posted September 17, 2016 Interesting.. You expect a bit more power ? .. or just another source for the turbo's. What vehicles are those turbo's in ? Quote Link to comment Share on other sites More sharing options...
