RustyNissanPrairie Posted October 25, 2014 Share Posted October 25, 2014 Random thoughts/musings! I have a Defender 200tdi that im rebuilding to go in my 110. The 110 has a new drive train - ie Ashcrofts late spec (suffix D? IIRC) LT77 and a brand new 1.4LT230 so Im wanting to keep the existing set up rather than going to a R380. The engine block is in pretty poor condition and is being bored/linered as we speak. All internals are being replaced. The turbo is shot and is only fit for the bin but I was going to fit a VGT from BAS (if they still do them) I've not checked the head yet but i'm assuming the worst although I do have a spare head that I've not 100% checked yet but it is flat and uncracked. As I understand - a 300tdi head will fit a 200 block BUT wont work because the pistons, injectors, FP and obviously manifolds/turbo are different between the two engines. Now..this is where my musing's come into it I need to fit new pistons to my 200 bottom end when its finished machining, but I could fit 300tdi pistons and build the rest of the engine as a 300tdi ie head/manifolds/turbo/fuel pump/injectors/timing chest That way I can still use my gearbox and mount the engine in the original 200tdi easy to work on forward position because of the 200block engine mounts but have the 300tdi advantage's of slightly quieter sequential injection fuel pump, serpent drive belt/bigger alternator and new cylinder head availability.

Gazzar Posted October 25, 2014 Share Posted October 25, 2014 Will the conrods or crank be common between the engines? Parts book time! Quote Link to comment Share on other sites More sharing options...
western Posted October 25, 2014 Share Posted October 25, 2014 IIRC from the 200 & 300tdi engine parts section the head gaskets are common to both engine types, so there can't be much difference between the cylinder heads/block faces. you can check part numbers using this http://www.retroanaconda.com/landrover/parts_books/110/3_engine_200TDI_300TDI_V8_p168-299.pdf Quote Link to comment Share on other sites More sharing options...
ejparrott Posted October 25, 2014 Share Posted October 25, 2014 You should change the pistons, but some people claim to have not bothered...that's about it...I have 300 turbo on my 109 with 200 disco inlet Quote Link to comment Share on other sites More sharing options...
RustyNissanPrairie Posted October 25, 2014 Author Share Posted October 25, 2014 the angle of the injector is different on the 300 head compared to the 200tdi's apparently and so the pistons have corresponding shaped recesses in the piston crown, besides I need to buy some new pistons regardless so could just buy 300tdi ones instead. Cheers Western - i have parts ID manuals and there is info out there regarding a 300tdi on a 200block but most people dont bother due to having to change pistons to suit the 300 heads. Im now thinking about the possibility of keeping the 200 timing case as the water pump is in a better position compared to the 300 but being able to fit the 300's fuel pump. Kinda best of both worlds1 Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted October 25, 2014 Share Posted October 25, 2014 200 and 300 injector pumps are the same...... Quote Link to comment Share on other sites More sharing options...
ejparrott Posted October 26, 2014 Share Posted October 26, 2014 As David says, 200 and 300 pumps are identical Quote Link to comment Share on other sites More sharing options...
GW8IZR Posted October 26, 2014 Share Posted October 26, 2014 There is always a risk with this kind of thing, in two years time when you need an XYZ you will be sat scratching your head thinking now what did I use. Unless there is a compelling argument like loads more power, far better reliability or far better economy etc then standard wins every time. The more standard things are the easier to maintain..

Diesel_90 Posted October 26, 2014 Share Posted October 26, 2014 Why don't you just fit a complete 300tdi on the lt77? Quote Link to comment Share on other sites More sharing options...
