Resurrecting this one to see if anyone else has ever used the setup initially suggested in the title and first post? It turned into more of an ACME/DIY adapter alignment thread, but I thought this was really critical information at the beginning for those looking to build a higher powered VW turbodiesel paired with a Toyota v6 R150 or Jeep4.0L/DakotaV6 AX-15.
Cost is a bit spendy, but cheaper than ebay price for an 86-87 22RTE USA turbo pickup application R151F to 22R bellhousing + a Diesel Conversion Specialists Adapter plate and crank flange spacer/flywheel adapter...
$1379 for this route with the Quick Time RM-4082 dowel pinned racecar grade steel VW 4cyl to GM 4 bolt Tremec/Muncie bellhousing (accurate to .0005"!!!) + Novak Adapters GM 4 bolt Tremec/Muncie Bellhousing adapter plate to Jeep/Dakota AX15 (and 1996+ Toyota R150 - longer input shaft than earlier 86-95 R150/R151)

vs approximately $1100 give or take if you can find the elusive R151F 22RTE 86-87 turbo pickup bellhousing off ebay $475 or so... if and when you can find one, + the $620 DCS adapter plate:

(Gas To Diesel Conversions makes a similar adapter to the DCS, but it costs a little more and is a 2 piece modular adapter)
I have a 22RTE R151F turbo truck bellhousing now and am planning on using that setup with the DCS adapter and as many other parts as I can use from ACME in making an ALH swap into a Samurai (glow plug harness+relay, filter housing, etc - Have to support Jeff @ ACME for all he continues to do for these swaps, just know that you need to check alignment if you buy the ACME kit...)
I also have been planning for years to use this Dakota V6 Magnum AX15 that I have and that Novak GMAX15 adapter plate to go into my 1962 GMC big block V6 to have an overdrive trans for good unloaded freeway cruising. The AX15 doesn't do well with hauling big loads in 5th due to the retainer design of 5th gear, sticking back on the rear side of the mid plate on the end of the shaft. That is, if I don't find a deal on an NV4500 from a Dodge diesel application beforehand... that will really beef up the strength of the drivetrain, but the big block 351C V6 (900lbs) and the Dana 44 rear already weigh a ton, plus a 230lb NV4500 5 speed... the AX15 will be way more fun and enjoyable and with a useable first gear for normal driving, just can't haul heavy loads in overdrive 5th. Perhaps upgrading to R150 clusters may be the solution, they don't have that AX problem. Or run an R150 2wd 1996+ trans
