You just swap over the rear output/stub housing from the old tcase...and problem solved

Seriously…we've swapped in at least 5 donor LT230's into trucks without rebuilding them and have had zero issues (including my 110 and D2). Check the intermediate shaft to see if it's leaking on the donor, if it is, don't buy it. Use your output housing and you can use any year LT230.

I've seen lots start leaking soon after. Why would you not rebuild? It is easy and low cost.

He is spending big money on a new gearbox. It would be crazy to run a used and unknown transfer case.

LT-230's mostly fail from fluid loss or offr-roading with the center diff unlocked, not wear. I also wouldn't bother rebuilding one. I would just reseal it.

I've not…both of the donor cases I've installed in my trucks haven't (or the 3 other trucks) and I beat the living shit out of my D2. The D2 even has a under drive bolted up to it and I've had zero issues.

OP choice either way



A question for the guy's running this engine swap upgrading your brakes and driveline

Would you rebuild a used diff before installing it?

I sent a note to Goran so we'll see what he can find.
Could not find an OM617 dyno result with one of Goran's IPs online yet, but here is one from an OM606 below that has the same 3.0 liter displacement and a very similar (same generation) IP although with 8mm plungers (verses Howard's 7.5mm).

This is so new that there may not be specific results to Howard's configuration available.
I think Howard got one of the first of the OM617 external ALDA 7.5mm M-IPs.
I'll check on http://www.superturbodiesel.com/ to see if anyone else has the same IP as Howard that has been tested and get some results because I'm curious myself.
For now take a look at these impressive results.

From Goran's facebook page:
566bhp and 586.7lbft at the wheels, im very very happy now.
This is almost 680 engine HP. 795nm whp 2,8bar boost and yes its a OM606. 700hp is The next limit to break. Do We have any 700hp+ OM606 out there? Not assdyno now. Real figurers.

Got a response back from Goran saying that he does not have a dyno result, but still checking.
Here's what he said:

No I dont have the dyno test sheet here, but I know for a fact that the 617 can go 250 hp.

Unless someone has dynoed one, then nobody know for sure. It is ridiculous (in my mind) that anyone would be tuning an engine to double stock power without involving a dyno.

So what crazy levels of boost are being used to get to that amount of power?

Pretty much every kid with a early P-Pump cummins do this, and they generally do not dyno them.

I think basically,
It's like the older semi diesel's, Cat ,Cummins n Detroit, at one time you've heard that they've been "turned up", the older diesels that was a common thing to do to get more HP, most did it till the engine ran to the owners performance needs/ego.
Because of the ability to do this,set to ego,most were not dynoed as ever engine had different applications, the M-pumps Hp your requesting to see would be kinda the same, I can run the fuel up ,turn it up, or keep it low, it's kinda sweet from what I understand but still on a very long learning curve to get it right.

Would like to know tho what years of the LT230 came without a central locking diff, read it a bit back and cannot find it again, currently reading on suffix codes to try n better understand tho still escapes where the mentioned information was found.

Not knowing anything specifically about the OM617 - but assuming the basic physics of engines doesn't change: assuming 80hp NA, then 250hp would require around 2 to 2.5 bar boost. It's within the realm of reason. But given that it's a 4-banger running >2 bar boost, it would be a dyno queen - very little bottom end. Could be done with GT28 or larger equivalent hybrid turbo.

Folks, looking for a LT230 was what was intended,

Maybe this should be moved over to Super Turbo Diesel, over there it's dedicated to this type of engine performance queries.

No I'm not educated enough to answer all of the om617 related stuff, I'm a knuckle buster n reader.

Just looking for LT230 information was the question.
Reasons for used... $$$$ spent on engine n gearbox, used is cost effective n plentiful vs new. :--)

From the GBR Utah site:

Discovery 2’s – Note, you must make sure you have a compatible transfer case. Land Rover removed the activating mechanism for the central differential lock starting with the 1999 Discovery 2. They felt that Electronic Traction Control was effective enough that a functioning CDL was not needed. Subsequently they decided this was not the case. Factory D2’s also have a detuned version of ETC. Fortunately they left the important internal components inside the transfer case at least until mid 2001. At this point, unfortunately they even removed this internal stuff. Due to an out cry of enthusiasts, they were supposed to add it back in along with a cab operated activating mechanism in 2003 but this didn’t actually occur until 2004. So mid 2001, 2002 and 2003 Discovery 2’s do not have an appropriate transfer case. If you do not have a compatible transfer case you have several options as follows...

This was all answered at the beginning of the thread. Go to the junk yard and get a transfer case from any Discovery 1 or 2. As above, some Disco 2s don't have a CDL, so don't take one of those....

My suggestion... Reseal it at a minimum. Three shaft seals, two intermediate shaft O-rings and all gaskets. Better to take it apart and replace all the bearings, but if you are lazy, they are usually fine.
