Andicog Posted March 22, 2019 Share Posted March 22, 2019 Hi, Wondered if anyone knew the air inlet o/d on a standard 300tdi turbo? I have a 110 Tithonus fitted with a 300tdi with lt77 and want to fit the proper 300 air filter housing and locate it on the air con pump mounts so I can run to a snorkel on the drivers side wing. I'm told that the original Defender air pipe from the turbo won't fit as my engine is further back than the factory position due to the lt77. It does look like there's enough room to get a 2.5" or 3" alloy/silicone hose around the back of the engine but I wondered if anyone has done it? I'll try and post some pics of the space I have between engine and bulkhead. Any help appreciated. Quote Link to comment Share on other sites More sharing options...
Troll Hunter Posted March 23, 2019 Share Posted March 23, 2019 I've just measured mine and it's 50mm diameter plus, of course, the diameter of the securing rim. Mike 1 Quote Link to comment Share on other sites More sharing options...
Anderzander Posted March 23, 2019 Share Posted March 23, 2019 I have a 300 turbo on my 200 and fitted the airbox where you’ve got it. I used silicone elbows and stainless pipe to route it round the back, OE bobbins and brackets to mount the airbox, the rear lifting eye mount to hold the pipe, and a silicone reducer from the airbox to the pipesize. 1 Quote Link to comment Share on other sites More sharing options...
Andicog Posted March 23, 2019 Author Share Posted March 23, 2019 Thanks guys, really appreciate your help, I've already bought the air box straps and rubber bobbins just need to make a bracket to fit onto the air con pump mounts, was thinking 5mm steel plate. I'll then fit the snorkel, have found a 3" car exhaust stub with a flange so will mount that onto a plate that mirrors the shape of the snorkel and bolt them together through the wing panel, then it's 3" flexible pipe from snorkel to air box and get a reducer and some alloy and silicone tubing to run to the turbo.

Anderzander Posted March 23, 2019 Share Posted March 23, 2019 5mm plate 😳😮👍🏻 Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted March 23, 2019 Share Posted March 23, 2019 I'd go through the wing through the top blanking plate on top of the wing through a plate made to fit, 3mm/10 gauge will suffice. Brings you out nicely for the airbox. HTH Mo Quote Link to comment Share on other sites More sharing options...

HTH Mo I've already got the Masai 300tdi metal snorkel that clears the roll cage (after buying a normal metal 300tdi snorkel because I was told I could trim the inlet tube down to clear the cage . . Wrong!) I also bought the 300tdi inner plastic air box/duct but they're pretty flimsy hence my all metal inner part idea! To do the wing top would mean removing and trimming the MOD installed checker plate as it covers the drivers side wing top vent. Having said that you've now got me thinking . . . 👍 Edited March 23, 2019 by Andicog Quote Link to comment Share on other sites More sharing options...

Anderzander Posted March 23, 2019 Share Posted March 23, 2019 I think so. Unless you want to mount suspension on it too ? Quote Link to comment Share on other sites More sharing options...

I always err on the side of caution! What would you recommend and shall I cancel the heavy duty drivers side spring I ordered? I do have some 4mm alloy but wasn't sure about the vibration. 😂 Edited March 23, 2019 by Andicog Quote Link to comment Share on other sites More sharing options...
Anderzander Posted March 23, 2019 Share Posted March 23, 2019 It’s up to you 😊 Here’s mine with a snorkel top pushed onto the airbox. I just used sheet steel of similar thickness to the airbox and straps. Quote Link to comment Share on other sites More sharing options...

Appreciate your help, did you run 2.5" round the back of engine with reducer on air box or 3" with reducer on turbo? Quote Link to comment Share on other sites More sharing options...
Anderzander Posted March 24, 2019 Share Posted March 24, 2019 Reducer to the airbox. Mine is in a series without an intercooler - the inlet pipework runs where you want it. These are the best pictures I have on my phone for it at the moment: 1 Quote Link to comment Share on other sites More sharing options...
Andicog Posted March 24, 2019 Author Share Posted March 24, 2019 That's great, thanks again, nice neat installation you have there. 👍 Quote Link to comment Share on other sites More sharing options...
Andicog Posted March 28, 2019 Author Share Posted March 28, 2019 Moving along a little, bracket roughed out from 5mm alloy. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted March 28, 2019 Share Posted March 28, 2019 You know, going in through the wing top would work really well for that 😉 That's a really shiny install Stephen 👌 @Anderzander Mo Quote Link to comment Share on other sites More sharing options...
