gothbiker Posted December 31, 2016 Share Posted December 31, 2016 i bought a secondhand vnt turbo set up, I'm having problems with the actuator, i cant seem to get it working, the vains in the turbo move, what has everybody else fitted? I've found the information for a 2.8 tgv actuator but nobody can find one for sale, I've found this picture of a set up, has anybody tried it? I've tried turbo technics and they weren't very helpful apart from phone bell auto services up Quote Link to comment Share on other sites More sharing options...
Turbocharger Posted January 1, 2017 Share Posted January 1, 2017 Blimey, your diagram looks complicated. I'm running a Mitsubishi VVT on a 300Tdi, I have a Td5 boost capsule with an external spring (chosen by mostly trial and error, with a little science stirred in) to counterbalance the closing force. That moves the vanes and manages the boost. The result is great, really boosty at low revs, I see 0.8 bar at 1000rpm and 1.3bar at 1400rpm. It naturally targets full boost though so the vanes are always as closed as possible, which I think contributes to 25mpg (mine is an auto Ninety too). The hardest part was making the manifold to hold the turbo, it's run for about five years now and it's great. I've been to Spain and Morocco with it, it's really tuneable but I've turned it down now to keep it driveable. Quote Link to comment Share on other sites More sharing options...
Anderzander Posted January 2, 2017 Share Posted January 2, 2017 Turbo - do you have a thread with details of what made you go with the Td5 actuator? Quote Link to comment Share on other sites More sharing options...
Troll Hunter Posted January 2, 2017 Share Posted January 2, 2017 Turbo, also, what made you choose a Mitsubishi turbo and what model is it from, please? Did you create a thread of your upgrade? This info could be really useful to other members lusting for a VVT. Mike Quote Link to comment Share on other sites More sharing options...
gothbiker Posted January 2, 2017 Author Share Posted January 2, 2017 thanks for your replies, by any chance would you have a photo or diagram? i bought a manifold that had been made to fit, so i was lucky there! just the actuator I'm having problems with Quote Link to comment Share on other sites More sharing options...
Ex Member Posted January 3, 2017 Share Posted January 3, 2017 The stock ones use a boost diaphragm, not a vacuum one. Just buy a boost diaphragm. Quote Link to comment Share on other sites More sharing options...
Turbocharger Posted March 12, 2017 Share Posted March 12, 2017 Bit of a hang time on this but I've been busy... Here's some pics of my setup, homebrew manifold and the turbo from an L200. It's not pretty... Boost control is just by pressure through a Td5 diaphragm and a counter-pressure spring to reduce the pressure for first movement. The effect is excellent pullaway performance (through an auto box) and comfortably 25mpg or better on a run. Quote Link to comment Share on other sites More sharing options...
