petrol t diesel engine swap.
« on: September 05, 2010, 23:55:00 »
I have finally had enough of trying with my 2.25 petrol engine, tried everything to get it running, compression is good, has a spark fitted a known good head thinkin it may be warped or cracked, replaced the entire ignition system and fitted a new carb!!!!!!!!!!!!!still no joy. SO i have sourced a 2.25 diesel lump and am soon going to swap them over. Is there any particular pitfalls i should be aware of? or anything peculiar i should know about? Many thanks guys, Fuzz.

The main thing is that you need a fuel return to the tank and thats about it.

I did think that would be all but always best to be sure!! It's an ex military model with twin tanks..so I'm right in thinking that I only need to plumb the return into one of the tanks?

you'll also need to get hold of the throttle assembly.  I kind of fiddled with all the linkages and made up a rod so that it worked of a series of rods rather the original rod to cable set up.  you'll need to do something about the vaccuum too.  the diesel has a butterfly valve in the intake that's connected to the servo and a vac resovoir. I did away with all this and fitted a vac pump off a MGF (sorry for my spelling in this).  I made up a twin pulley to run off the water pump.  brakes actualy work now :)
