Quick question for the experts. I have a 2.25 diesel fitted which has a crack in the block running the entire length of the engine. I've got hold of a 2.25 petrol which I'm going to put in but it hasn't got a flywheel housing or flywheel. I'm thinking of just swapping the housing and flywheel from the diesel engine onto the petrol engine. How much of an impact do we think the heavier flywheel will have? I can use the heavier duty diesel starter motor as well which can only be a bonus.

I can't see why it wouldn't work, but it's not going to be a very nice drive - revs will be slow to rise and fall.

if you can get hold of the bell housing and flywheel and starter from a petrol you might be better going that way.

Thanks both, confirmed my thinking really. LR used different weight flywheels for a reason so I should stick with that. Housing and starter motor are easy to come by, flywheels less so unless I splash out a couple of hundred quid on a new one. I'll keep searching.
