Aragorn Posted September 1, 2006 Share Posted September 1, 2006 ok guys can anyone tell me the reason the disco tdi causes all the problems when fitting in defender is the exhaust manifold different putting the turbo closer to bulkhead or does the engine itself sit in different place?? cheers Quote Link to comment Share on other sites More sharing options...
western Posted September 1, 2006 Share Posted September 1, 2006 Simply the exhaust/imlet manifolds are a different design, turbo is mounted lower same as a 300Tdi engine, which means if fitting one of these 200Tdi's the turbo exhaust outlet sits very close to the chassis rail & bulkhead, have a look at the Tech Archive --- fitting a Disco 200Tdi into a 90 by Les Henson -- with pictures.

Matt Neale Posted September 1, 2006 Share Posted September 1, 2006 ok guys can anyone tell me the reason the disco tdi causes all the problems when fitting in defender is the exhaust manifold different putting the turbo closer to bulkhead or does the engine itself sit in different place?? cheers Briefly, the block is identical. The timing case is different, as is the arrangement of the manifolds. On the Defender engine, the exhaust manifold (and therefore the turbo) is mounted above the intake manifold. On the Disco it's the other way around, with the turbo mounted low - exactly the same as per the earlier TD engine. (In point of fact, the 200 Tdi Defender engine and the TD are directly interchangeable - the Tdi will bolt straight in - even the exhaust fits straight on.) The Disco engine will mount on the Defender chassis and bolt up, but the exhaust won't clear the bulkhead due to the position of the turbo. Companies like Steve Parker have produced a bespoke downpipe which will allow the exhaust to clear - others have made up a new pipe themselves. That's the simplified version - have a look in the tech archive as I'm sure that there is a at least one writeup on fitting a Disco 200 tdi into a 90/110. Hope this helps.

Aragorn Posted September 2, 2006 Author Share Posted September 2, 2006 does the defender 300tdi engine have the turbo underneath like the disco 300tdi? if so how does it clear bulkhead? are the 300tdi's easier to fit or just the same? and whats the difference between the 200 and 300 engines? cheers guys Quote Link to comment Share on other sites More sharing options...
western Posted September 2, 2006 Share Posted September 2, 2006 all 300tdi & DiscovertyRR 200tdi engines are externally almost identical, in a defender the 300tdi sits higher & further forward, above the front axle which gives the space for the turbo/manifolds, the gearbox bell housing & mainshaft is longer to allow this to connect to the engine. some 300tdi engines have a EGR system, others have a EDC system, 200's don't have any electronic systems extra EGR = exhaust gas recirculation EDC = electronic diesel control Quote Link to comment Share on other sites More sharing options...
davidlandy Posted September 2, 2006 Share Posted September 2, 2006 fitting a disco 200tdi into a 90td at the moment - oh what fun! the engine is in but we are now onto the fiddling things like working out how to run the interccooler hoses and chopping out the inner wing. also got to secure the clutch hose somehow now as its hitting the exhaust downpipe after i chopped the little bracket off the bulkhead. hunger has meant a break !
