Ok guys I have been talking to a friend of mine who just bought a 110 with a 200tdi in it. His first Land Rover. He is a gear head and his trade was diesel mechanic. We have been talking about getting more power out of 200's.
We would like to know what you have found to be the limitations of this engine? What type of carnage have you had on your quest for more power? Also why did you have that carnage? Who has really pushed these things to the limit?
Any and all input is appreciated. Thanks in advance.
Like most small diesels, the main limit is displacement.
The 200TDI head is a weak link because of the small bridge between the valves.
The 300TDI head will fit the 200 and is an upgrade to consider along with the head bolts Les mentioned.
The 300TDI Discovery manual IP has a separate fuel enrichment lever on the side of the pump that you might consider as well as it will also fit the 200.
You may want to talk to ACR and Turner in UK.
Since the 200TDI shares the same basic 5-main block as the 2.25/2.5 petrol, it will be worth while to understand what they did to increase a 2.25 petrol out to 2.8 liters.
I don't know the particulars, but seem to recall that it required a special crank and or rods, but could be wrong.
When I spoke to them many years ago (when I was trying to increase a 2.25 petrol to a 3.0 liter displacement), they were NOT using the international stroked out 300TDI diesel crank and rods (which I think may not fit a 200TDI block).
If a larger intercooler and turbo are used, the fueling capacity of the stock pump may pose limits.
As John mentioned be wary of the head gasket.
I am sure there are shops that can increase fuel output to supply a 200TDI that needs more fueling, but don't know of any off the top of my head.
Too much boost in the 200TDI will vaporize the crankcase oil and create a disappearing act that will baffle the best... so make a note if and when you are over 20 PSI.
I have talked to several people who connected a low pressure propane boost with great success that did wonders for performance, but I have no experience overall. Generally they are set to only add propane when the petal is mashed down all the way in 3-4-5 gears.
150HP is a reachable goal John mentioned, just how much do you want to spend to get there is the real question?
Keep us posted as to how this works out.
