So I have finally come accross what I consider to be a "good deal" on a 93 6 cyl cummins with all accessories turbo and intercooler with 180k on it, and have decided the cummins swap is a go.
Couple specific questions
-Anyone have a hydroboost setup working with the cummins? I just did the conversion and don't want to lose my superior braking.
-Does the ZF5 need to be moved back any to fit the 6bt in there? Research seems to show it needs to be moved 2 inches aft, which sounds like a pita. I am hoping to keep my zf5 and bw1356 xfer case, as I have a gearvendors unit with the adapter for the 1356
-From reading on oilburners, many are saying avoid the zf like the plague, I can pick up the getrag 360 that is still behind the cummins atm, and appears to be MUCH cheaper to rebuild, but then can I mate it to my BW xfer case and save my gearvendors usefulness? if so I could remove the cost of the adapter plate from my swap and could workout; could still go either way with it. I dont have any interest really in paying for a NV4500 trans as I have seen too many failures of them behind gassers and diesels alike. the ZF seems to hold up well even behind moded strokers, though they have an interwebs reputation of being week.
-Destroked seems to be the go to source for the adapter plate, mounts, and other misc stuff. Do most people use the adapter plate that uses a 6.0 starter? or the one that uses a cummins starter.
-The guy selling the motor says the pump needs new governor springs which i was planning on upgrading anyways, thinking of having whole ve pump rebuilt while motor is out, I figure it has probably never been rebuilt before. Maybe even send it out to conestoga diesel if he has any interest in working with cummins pumps, that way I know its a quality job. His evidence for it needing new springs is that it will surge on idle sometimes, which sounds like it makes sense, but can anyone confirm it? I have very limited experience with cummins engines.
- I am only looking to modify it up to 250hp, maybe 300. I live at almost 5000 feet elevation now, and towing up here is a lot tougher then down in Tucson, my nonturbo idi used to be great down there. The rotary pump seems to be more then capable of these numbers, any other reason why i should spring and spend a lot more money for a P pump?
The entire truck is for sale, and I could pick up the getrag trans, xfer case, and both front and rear axles for an additional 1000 bones, wonder if that route is even worth looking into? Would save me the money of eventually swapping in a dana 60 from a f350 which seem to basically be made of gold.
Any additional advice would be extremely helpful. Will hopefully pick the motor up in april, and gather the parts over the next month or 2, so it wont happen for a little while but I am trying to account for all possible hurdles before I take the truck out of service, as I am going to have one irritated wifey if she is driving me to work at 4 30 am for a month while the truck is down haha, hoping I can get it done only having the truck down for 2 weekends and one workweek.
I was thinking about buying a newer truck the last month or so (my idi motor has NOT proven reliable to me at all since I have owned it, and at 320k i am ready to get it outta here) but the value of used cars that are beat to **** and have 200k miles seems to be on the rise every day no thanks to "cash for clunkers" and personally I dont think there has ever been a truck as goodlooking as my 92 supercab longbed.
Thanks in advance for any advice! Not including the motor, turbo, accys, etc, im trying to keep the cost of the swap below 3k, if im being unreasonable let me know.
