I am currently looking for a 240 and found 3(!) in my area that match what i want(a 5 speed).The only problem is all 3 are either 89 or 90's.What i wanna kno is how hard is it to swap a DE in? IS there anything else needed other than the engine?Will the trans work fine? Also i hear that that using the pistons from a SOHC engine are higher compression than the ones in the DE so u can use them in it. Is this true and would it be smart for me to do once i swap out the SOHC for the DE?
What's wrong with the SOHC? There's plenty of aftermarket out there for it, has a better low end, and that miniimal gain from the DOHC is hardly worth the trouble of a whole swap if the engine's fine.
