CwazyWabbit Posted August 5, 2012 Share Posted August 5, 2012 The gearbox is different between the two engines, see http://forums.lr4x4.com/index.php?showtopic=60070 not sure about engine mounts.... Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted August 5, 2012 Share Posted August 5, 2012 Ignoring the question of why (it would be one hell of a step backwards in terms of engine perfomance!), then it's no more complicated than wiring a Tdi with Td5 looms which has been done before successfully.

minimaquinas Posted August 5, 2012 Author Share Posted August 5, 2012 hi james the step backwards is because i have baught a realy clean 35.000 kms 110 with a blown engine very cheap and i have a 300 with only 111.000 kms and also i dont like td5 engines they have too many bits that go wrong Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted August 5, 2012 Share Posted August 5, 2012 You'll need to change the throttle pedal as well and various other bits and pieces I imagine, such as pipe work etc for intercooler and the like. Quote Link to comment Share on other sites More sharing options...
discomikey Posted August 7, 2012 Share Posted August 7, 2012 the good news is, aside from the gearbox, where the bellhousing may be different (but could get an adaptor plate made up (look into making sure clutch works properly too, ive had no experience with adaptor plates so i dont know how they affect clutch pedal performance. anyway, aside from that, a 300 TDI is made to fit into an engine bay, so you can buy all the bits you will need of you dont think you can make them or make do with what you have. im not 100% on engine mountings, although something to research is poeple have done TD5 to TGV conversions which as far as ancilliaries and mountings is the same as a 300tdi conversion.. also have a look for 300tdi - td5 conversions as this will show what to do, but backwards.

rusty_wingnut Posted August 8, 2012 Share Posted August 8, 2012 you don't need an adaptor plate - you need an R380 300 bellhousing and inputshaft..... Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted August 8, 2012 Share Posted August 8, 2012 The engine mountings are completely different. Quote Link to comment Share on other sites More sharing options...
Diesel_90 Posted August 8, 2012 Share Posted August 8, 2012 The r380 td5 main shaft is different to a tdi I thought? Quote Link to comment Share on other sites More sharing options...
simonb Posted August 8, 2012 Share Posted August 8, 2012 It is, that is why rusty wingnut said to change the input shaft to the gearbox. Quote Link to comment Share on other sites More sharing options...
oneandtwo Posted August 8, 2012 Share Posted August 8, 2012 Converting a TD5 gearbox to 300 is dead easy - If you can pick up a 300TDi disco R380 (very cheap now) you can easily convert it to fit a defender with 300 engine and gearsticks in the right place in under an hour using the existing TD5 R380 box. If you pull the outer housings off each one (6x M10 bolts and couple of detents) the gears/shafts come out in one whole unit. You need to swap the selector rail from the TD5 box to the 300 disco box which can be done in situ without stripping the gears apart or requiring any special tools. Bolt the disco box back together and use the TD5 shift top shifter housing / yoke etc. Quote Link to comment Share on other sites More sharing options...
