hey mike-81-240d not that this is a very technical response but my friend up in woodstock,ny did it with his. he said it was very time comsuming and wanted more power so he swapped out his 4 cyl for the 5cyl out of a 300d. he said it was total drive train replacement including trans and driveshaft.

Why not just find a turbo engine? I'm sure you'll enjoy it more especially with the time and energy you'll be putting into it

I agree with McLovin... err.... Pao... If your going through the hassle of a swap, you should to it right with a 617.95x turbo motor. Especially with your 4 speed.

Still, going from a 67 horsepower motor to a 88 horsepower motor will be noticeable in throttle response, but you will still need the tranny to go with it I'm told. The driveshaft will also need to be changed since the driveshaft for the 300D is going to be shorter than the one for the 240D.

Many have done this conversion, it's entirely doable. You have to balance the crankshaft and the flywheel together to make it proper but some have just bolted it on. Some have had vibrations in the low 2000 rpm range up to 3000rpm as a result of harmonic problems. The driveshaft has to be used from the 240D since it is longer but either way the shaft has to be cut to length and balanced. The shifter rods will also have to be cut 4" or so to accomodate the same distance back due to the extra cylinder.

if you're gonna go to the hassle of a swap, put something in with some bawls. the gain from 240 to 300 NA isn't gonna blow you away. it's like 'very slow' vs 'barely tolerable'

this isn'y supposed to be fast i just wanted to be able to tow my boston whaler :) with 170lb ft tq and be able to change lanes on the freeway
Towing? A Boston Whaler? Seriously? Unless you have a very tiny whaler you're talking a boat that weighs quite a lot plus a trailer.....~2000lbs? I never got a scale weight but we used to tow 17 and 19 foot whalers in college pretty much every week.

In a car that may puts out 120lbft not 170lbft (that's the turbo spec) when it was brand new....

I wouldn't want you to be dissapointed.

Why not go for the 300D turbodiesel since it would take the same effort to swap out everything? And also, if you're going for a manual tranny, might as well go for a 5 speed, that is if you can find one.
