LT77 4wd->2wd
 

Hi all,
I'm taking the 3.5v8 out of a landrover to use for my engine. The LT77 gearbox that came out is obviously a 4wd box, but I know there is a 2wd version of the LT77.

So, my question is: Does anyone know if they are completely different beasts, or if there's some kind of parts kit to convert one to the other? I've tried googling around but I can't find any definitive information.

Cheers,
KEv.

You need to unbolt the transfer case then bolt on the 2wd cover. Finding one may be a pita though.

If you don't want the current set up I'll have it for my little 4x4 beastie:) :)

Kev,

As above (double post)

Now don’t take me as a complete authority on this but….

The LT77 gearbox uses a transfer box to create the 4WD, if you remove the transfer box you have a one out put gearbox.

I am going to go and lay under a Land Rover to check the gear leaver attaches to the gearbox not the transfer box!

Oh welcome, (good first question both my passions in one post):D

Right I have just crawled out from under a Land Rover, I could only find an ambulance!

As Coozer said really, or you could leave the transfer box on stick the diff lock in and have the widest transmission tunnel ever but a prop shaft that is about 20mm long.

Best search for a 2WD cover!:D

Welcome Rincewind, are you a Wizzard by any chance? I don't know much about landys other than they're uncomfortable animals but great off road, good job Ginge and Coozer have answered your question.

D.

I have been thinking a little more about this. (No comments you lot).

My first 90 had an LT77 and was screaming in fifth at 60mph the later R380 is a little better, has reverse in the right place as well.

I know the diff has the final say in the road wheel output speed but it might be worth thinking about.

Someone must make a rover V8 to type 9 conversion plate, and then you won’t have to mess around modifying the transmission tunnel.

Just thinking out loud.

I have seen a couple of rover v8 to type 9 bellhousings either on ebay or the v8 forum but they arnt cheep. I have also been told by several people not to go down that route because the type 9 wont be able to handle all the extra torque!

In the end i have decided to go with a lt77 gearbox from a tr7 as the 5th gear is taller and is actually an overdrive gear. cheap too, only cost £47 for the gearbox and it bolts onto the sd1 bellhousing with no problems.

There’s your answer is this any good?

Cheers Ginge

im not 100 % sure about that gearbox, im sure someone who knows more about gearboxes will have a look soon. The only thing i would say is that bell housing wont fit on the v8. As far as i am aware you also wont be able to use a 4wd bellhousing because they are too long......

Thanks for all the replies, guys.

It looks like the short answer is, no I can't do an (easy/fairly cheap) conversion - it''ll be much easier to sell this box and get another one - the Borg Warner T5 seems to be a fairly popular choice for this engine.

So Coozer, if you want to make me an offer for the gearbox (with or without transfer box), PM me ;)

sound to me like you should be shoping for a borg warner t5 from an v8 tvr or such like
cant rember what mgbv8s or sd1's had could also be a t5

loads of 2wd cars had a rover v8 so it shouldnt be to hard to find a cheapish box to bolt up directly

nobody wants old thirsty v8 now so it should be pritty easy to find somthing from a scrappy or ebay

Cheers Rince, whereabouts in the world are you? Transport considerations are at the front of my mind....

Just to add something, I had a LT77 in my Striker. The Rover 4 bangers don't have a bellhousing patterns on them, they use adapters. SO, I had a setup from a Sherpa van that could easily be re-drilled to accept any engine you want.

That would be my plan to mount my spare T16 turbo engine to your 4x4 box for my little off road project. That would make it go!

I'll have the lot off you if your not miles and miles away:) :)

LG,
Steve
