Re: ForcedInduction's 240D 3.0VNTi - ForcedInduction - 09-16-2008
Update.
The vacuum actuator controlling boost based on load works great and I rarely hammer down so the intercooler isn't really useful to me. I've removed it in favor of even better turbo response.
As a result, the dual air filters are no longer necessary since the air tubes are gone. I've installed a single Fram 8038 air filter with 3" induction tube all the way to the turbo inlet as well as a better and remote installed (easier to view) Filter Minder. The 8038 filter is the same surface dimensions as the old pair of filters but it has a much larger filtering surface area from more folds.
Eventually I plan to install a shield to isolate it from the engine/radiator heat.

New engine bay shot. Up next is installation of a Kalifornia air filter system.

No more I/C?
RE: ForcedInduction's 240D 3.0VNT - ForcedInduction - 02-12-2009
Nope. I don't run it hard enough for one to do much more than add lag.

How long was the piping to the intercooler? You think shorter piping would of helped? I've been holding off on my A to A IC project for sometime, this seems to be good info. It gets too hot here 100 degrees plus, that the car bogs down during the summer.
RE: ForcedInduction's 1980 240D 3.0VNT - ForcedInduction - 03-08-2009
About 5 feet total. It will help but I made it as short as possible. I'm going A-W on my 300D.
RE: ForcedInduction's 1980 240D 3.0VNT - DeliveryValve - 03-08-2009
You going with Bryan's A-W setup?
RE: ForcedInduction's 1980 240D 3.0VNT - ForcedInduction - 03-08-2009
Similar but in a different location, a cold air intake and a Holset.
RE: ForcedInduction's 1980 240D 3.0VNT - ForcedInduction - 05-18-2009
Got the 3.46 swapped for a 3.07. 1st gear acceleration actually seems quicker but 4th feels luggy more often.
RE: ForcedInduction's 1980 240D 3.0T - ForcedInduction - 07-20-2009
The GT2256V is off the engine, to be swapped onto the 300D. The 300's Garrett T3 will go on the 240.
As it sits now.
RE: ForcedInduction's 1980 240D 3.0T - ForcedInduction - 10-08-2009
The T3 turbo is on, the engine runs well besides the knock and its ready for winter work. I also backed the throttle stop all the way out to limit power.
RE: ForcedInduction's 1980 240D 3.0T - ForcedInduction - 02-23-2010
Big surprise today, the driveshaft fell out!
The nut came off the transmission tailshaft and the whole thing slid off the main gear shaft. Luckily it happened while pulling into a parking lot and not on the highway!
As luck would also have it, the whole thing happened next door to Heidelberg Motors and they were kind enough to loan me a deep 30mm socket and torque wrench to reset the nut. Their shop dog was nice enough to bite my ankle too...
RE: ForcedInduction's 1980 240D 3.0T - ForcedInduction - 09-26-2010
Compression cold
1- 340
2- 225
3- 340
4- 345
5- 345
Unlike the 300D which nails on the low cylinder and shakes a bit, this engine runs great despite the low cylinder (and the knocking wrist pin) so that low cylinder really came as a shock. I even changed the schrader valve in the tester because I thought it was an error.
Its averaging 26.4mpg and 35mpg on pure highway.
RE: ForcedInduction's 1980 240D 3.0T - ForcedInduction - 11-14-2010
Finally got around to replacing my bent left tierod, only to find the wheel bearings were thoroughly trashed by the curb impact as well. Cleaned and repacked it to drive home but it looks like I'll be driving the 300D this fall until I can find a new hub.
Also, last weekend I did the rear-battery conversion and installed the W115 manifold to get rid of that nasty EGR log.
RE: ForcedInduction's 1980 240D 3.0T - willbhere4u - 11-14-2010
I'll keep my eye out at the pick and pull yards for some hubs when we go looking for some calipers for my dads 83 300d
RE: ForcedInduction's 1980 240D 3.0T - ForcedInduction - 11-14-2010
I've got the ones off that euro 82 300D at pull-n-pay. It had new rotors and pads so $40 for the pair was pretty reasonable.
The calipers are still there and the hoses are in good condition.
RE: ForcedInduction's 1980 240D 3.0T - willbhere4u - 11-14-2010
good to know!
RE: ForcedInduction's 1980 240D 3.0T - ForcedInduction - 11-14-2010
Well, since that 300D was a euro with ABS nobody open Sundays carries the smaller wheel seal. Normal size is 70mm OD and ABS hubs need 67.5mm OD. Tom Judd found one in his parts bin but no twin, I'll have to get one from Westminster MB on Monday.

RE: ForcedInduction's 1980 240D 3.0T - willbhere4u - 11-18-2010
AH it's fine just needs to be repacked lol!
I bet the RH front one on my 300sdl looks like that it's a noise son bitch
RE: ForcedInduction's 1980 240D 3.0T - ForcedInduction - 12-11-2010
I added the driveline damper that was originally on the 300D I got my driveshaft from. It doesn't alter vibration (other than its pitch) when the engine is lugged 1000-1600rpm, but above 1600rpm its noticeably smoother when accelerating (especially at highway speeds).
As a note, the cut 240D shifter rods will not clear the damper.
