3.8 V6 into my bighorn

[FORGE1]

Well as per the title. When my 3.2 gives up the ghost the plan is to buy a 3.8 holden motor (super charged if I can get one cheap enough). does anyone know if my gearbox will bolt straight up or will I need to make some minor adjustments. They do look like a very similar motor and I havent had a decent chance to look at one up close to see. but would like to know if anyone has done this before or something along those lines. Mine has done about 280kms and isnt blowing any smoke or has any issues so I wont be looking at this change for a while but I may as well start getting ready with the way my right foot is with the old girl lol. Last outing which was reasionable driving (around town) I put $20 of 95 in and got 21kms so something cheaper running would be nice

Adapter plates have been made but its more common to use the auto that comes with the 3.8 and mate either a transfer box from the bighorn auto or a hilux to this

how hard is it to put the tansfercase onto the commy gearbox?
also is the mu auto the same as the bighorn one?

[geeves]

Ive never done it but do a search as there are others here that have

[slightlydodgy]

there was someone selling the commie trannie to bighorn transfercase adapters on trade me for about $300

Ok sweet. I was probably wanting to keep my Manual gearbox as thats my preference. I wonder if the housing are similar being both v6. Surely they make a adaptor plate for the 3.8 to the 3.2 5 speed.

If you get the early comadoor engine you will find that the manuals had a different crank. Find a wreck with a manual comadoor v6 and box and use that

if your doing it for fuel saving save your money for gas, not worth the hassel man

Actually the later isuzu 6ve1 manual box is identical bolt pattern to the 3.8 so bolts up. I am now trying to work out if this is still the case for the 3.2 6vd1 instead of an adapter plate
