It depends on how good of a deal you get on the swap parts. It will be close I think. I vote swap the 24v in there stat, the extra powa is worth the money if it costs more in the end.

So after driving on the freeway the other night my engine decides to take a shit on me.

After pulling off the head today I find this:









Since the block is messed up I have to find a new motor of choice.

I already have a m52 engine of out a 323 '97, but I am unsure if the cost for all the parts needed to install it would cost the same as buying another m42.

What do you guys think? Swap? Replace? Anyone seeing the parts I need for the swap? Anyone know the actual parts i need for the swap? An complete motors for sale out there?
