"I was confused when you say that the 38# will fit a 616 which no doubt is true but why would that even be considered to be fitted since the 38# is heavier for the extra 5th cylinder and the 616 is a 4 cylinder (240d)?"
Macdoe...... I have the 30# FW to install, but not in the 240D. this is going into the 85 300D to replace the 28# FW.
I re-read what I posted, and sounds like it was going on the 240.
Looking at the two FW`s side by side, that 30#er is one big heavy sucker.
weigh`s 1/2 as much as a 240D 4-spd manual transmission.
Now maybe if the 240 had a Turbo, that would speed up things?

I might have a 240D Turbo set up to buy next month, well know later when I go up to Portland, Or. (Daughter is having a boy) bought a Nissan Diesel eng off CL. the guy has some MB`s and extra stuff to sell, and has a brand new after market 240 turbo assy. well know in a couple weeks, almost forgot the guy had it, thanks for reminding me.
