Isuzu MSA Gearbox to LT230

5S splitter 0.762

31.65" tyres

3.54 diffs

When looking at the ratios the 5S in 1s, 2s and 3s compare closely with an LT85/1.222 LT230 in 1, 2, and 3 you'd then go to 4th natural which is marginally lower than the 4th in LT85 and 5th natural marginally higher 2300rpm at 110 kph (LT85 2400 at 110)

The one drawback is that 4S and 5 natural are almost identical so I guess it will be a case of seeing what works best. I'm assuming the normal use would be 1S-2S-3S-4-5-5S and then use 5S-4S to maintain roadspeed

So .762 is the splitter ratio?
I would be going tge 1.22 as well.
I have changed mine to a 5R box with a 1.192 tcase, i am much happier with this over the 5G and 1.003 and 1.22.

Had some wrong info on the split, if I were to use the 1.003 ratio set I purchased to upgrade the 28D box, (5th hi splitter in) the final would be around 1450rpm at 110. Not sure I need a 200kph Defender so think I'll stick to the 1.222 ratio.

Thats a fair bit different to mine Sheldon, is that due to the splitter? Also why just a hex head bolt in the shaft?

Yes different with splitter. This setup pushes the transfer case back 90mm from standard.

Vern, yours is recessed cap head primary to use a standard length bolt. No necessary on this shorter shaft.

i'm about to take the plunge and replace the LT95 in my 6x6 camper so will be having a read through the many pages here.

Given the PTO drive off the LT95 transfer I will be going the route of Keith and chopping the TC section off an LT95. Sheldon, will much of your kit be applicable to the MSA / LT95 hybrid box?

Also does anyone have a dead LT95 I can grab so I dont have to butcher my recently rebuilt LT95 or take the car off the road whilst I figure things out.

Lastly, anyone know of a good source for an Isuzu box?

(this is kind of a repeat of a post I just made on a thread Keith started specifically about the MSA /95 combo but I thought it might get more visibility here)

Thanks for the help!

Dave

Dave, re your queries, you also might try Sheldon on his ebay number 0488474020, and I believe he has Isuzu boxes (and of course continue to post your progress for our entertainment[thumbsupbig]).

Are these still on going or stopped I'm seriously looking at getting rid of my tired r380 and 300tdi and fitting the Isuzu combo to my defender

Still going. I just fit one of his new spud shafts and input gears. Try give him a call

Any idea on a rough price for the kit?
