Pajero/AWD tranny?


350whp

Recommended Posts

i heard somewhere that a Pajero tranny was used in the rally/AWD car. does anyone have any info on a AWD tranny swap? can it be done? any suggestion on a tranny to use?

Thanks

 

the awd cars had the 2L block IIRC so it wont work for our cars without swapin motors first

scooty dont.... when the AWD cars were built there was one 4g63... it was a wide block. The wideblock 63 is the same tranny mounting surface as the g54.

 

anyhow i agree with the previous poster, find a front diff, axle shafts, hubs etc. Then worry about a trans.

 

going totally custom... why not look into a subby setup with and adapter plate (that engine is in the right direction at least)

 

a guy with a welder, a plan,money, and a bucket load of talent can do just about anything.

 

The rest of us just do our best to build 12 second and faster RWD cars :)

I don't know what trans was used in the awd rally car, but I sure wouldn't use the Pajero/Montero/Raider 5 spd (km145). They are very weak and won't hold together for any length of time if you run more 150hp.

 

90% of the guys that drop a starquest engine in a Montero/Raider use the automatic trans.

funny I was just talking about some of this in an earlier post.

 

subaru tranny could work but same issue. there wouldn't be enough room left for the motor. bell housings on subbie trannies go past the front alxes.

there is a possibility of using galant VR4 front hubs, discussed on austarion.. also there are pics on austarion of the front hub setup on the 4WD evolution starion group B car in the mitsu museum in japan, after a member's visit there last year.. so yes it is possible i reckon..

 

and as far as the gearbox goes, maybe starion internals in the KM145? or a complete mazda B26 (carb type) gearboc from bellhousing to transfer case.. as we know the carby type B26 was the 4G54 engine, wide pattern block......

The group B 4WD cars had the engine in the stock position, but tilted nose up 6 degrees and was likely rear sump and/or the differential was integrated into the oil pan in some way.

The HKS 4WD car had the engine (DOHC 2.3L G54B Derivative) moved back so far that cylinder 2 was at the firewall and the engine sat entirely behind the front axle.

A GTR oil pan has the differential integrated into it. If you could fab up an oil pan to use the GTR diff, you may be on to something. You can get GTR diffs from most people doing RWD RB26DETT swaps since they usually swap to more traditional oil pans. Not sure what the gear ratios available are, but worst case you put a Nissan R200 diff out back too which certainly would be a move in the right direction.

 

There may be plenty of other donors, but this one is just one I've seen in person.

Here's the link to the pic thread: http://forums.austarion.com/viewtopic.php?t=1399

 

Its from 2004 and all the image links are busted. The guy has a -lot- of really good info on the cars though, worth searching his user name.

 

Jury is still out as to what tranny to use for my project. Stock KM145 won't cut it. I can attest to that fact as I had to replace the pilot shaft bearing in mine shortly after doing the turbo swap on my Montero and like all the other turbo Monty guys, I have my eyes peeled for a the auto KM148 for my van.

 

Still debating about whether or not I want to have permanent 50/50 or figgure a way to stuff a differential in there somewhere. A diff would be more ideal for street use, but a solid drive would be better for low traction situations. Suppose the best/easiest route would be a locking viscous coupler somewhere, probably at the front output shaft in the t-case.

 

Front end stuff is cake, worry about that later.

 

*edit* wow, I just noticed the post dates. Meh, the link still had good info.
