Problem fitting 300tdi, r380

Vehicle '87 110 CSW with original 2.5TD, lt77

Converting to 300tdi, R380

Been having a bit of hard times making this drivetrain fit. Engine mounts are in the correct locations, used the supplied jig, and verified with measurements.

Problem is the transfer case is hitting the driver's side (right) floor plate. Also, I believe I have the correct crossmember for the R380, but it seems I am missing a few brackets.

Images provided for reference. Any help would be greatly appreciated on how to correct the following issues:

Trans hitting floor (modify floor?)
Missing mounts for trans to crossmember
Rear driveshaft seems too short (modify shaft?)

Or, do I have a short version of the flywheel housing that is throwing everything behind it off?

Also posted on my build thread: http://www.defendersource.com/forum/...ad.php?t=46137


Thanks, Diego

You need the proper R380/tdi/V8 floors, tunnel, seatbox, and firewall adapter. Seatbox, floor, and firewall can be modified I think. You will also need the proper driveshafts. The 300tdi drivetrain sits 2" or so further forward than the old 4 cylinder setup.

This has been covered to some extent.

I was told that the 300/r380 with the crossmember setup was drop in and go for my 80's ROW D90...that is not the case and I had the same issue.

I decided to keep the old xfer case frame mounts instead of the crossmember mount. This kept the drive shafts in the same place and retained the position of the shifters. I have the longer bell, so the 300 frame mounts are in a different spot from Picts that I have seen on the net.

It is an option... $0.02,
Sean

Sean,

Thanks.

Just got finished up on installing the trans/transfer case mounts. I ran into similar issues, and addressed them in this way:

Transfer case right side hitting seat box (cut out a rectangular section of the seat box later to be re-fabricated to accommodate the transfer case clearance).

R380 crossmember and mounts I had did not work, so I re-used the old frame mounted brackets, and fabricated new steel trans/transfer case isolator mounts that bolt onto the transmission and transfer case,

Still need to address the driveshafts, as the front is too long, and rear too short. But there are shops that can tackle that project. Also, the trans tunnel will also be modified to allow for linkage clearance (cosmetics at this point).

In all, I feel pretty good about my custom set up, as it took me all day, but other than hardware, no costs were incurred. Will provide images when I'm up for crawling under the vehicle again.

Diego

They make a conversion kit to convert the LT seat box to the R380 seat box. Some of the early bulkheads had the tunnel cover plate bolted on. You can just change yours out for the R380 style. Safari HP had all of the conversion pieces including the tunnel cover in stock last I checked.
