Having missed my legnum that I sold 10 years ago, I have finally bought another. This time auto and FL but packed with a few mods already done to it. When I had purchased it at the beginning of the year it had already been fitted with front brembos, bc coilovers, mamba turbos, walbro 255, evo 7 wheels, timing kit and new genuine front LCA'S. Since owning it I had upgraded to a gtr35 cop kit, fmic, hot side piping, replace the tb elbow with a silicone/aluminium pipe and a dual fuel rail setup with a turbosmart fpr. But unfortunately last month the bottom end went ( rod knock). And that was fine as I had a 6g74,box and tcase from an awd magna sitting around doing nothing. So out went the 6a113 and the process to get the 6g74 in started. Before this all happened I was already building a 6g75 Mivec for it on the side so there was no better time to get the 6G conversion sorted out then now.

I will try to do my best and get a list of everything needed once the car is running under its own power. And as of tonight it runs and started up first kick. So the next step is to work out the mounting brackets for the front and rear roll stops, radiator hoses, exhaust piping for the single turbo off the stock headers, plumb the turbo up and get the p/s lines sorted. Once this is done I can drop it all to do a timing kit, replace some gaskets and build the auto.

Cool, when my motor blew I seriously considered putting a 6G75 in and eventually turboing it. Keen to see progress.

I assume you are running an auto? My understanding was the manual box will require an adaptor plate. There is a mob in Mexico(?) doing a limited production run now.

Edit: To use above you would still need the front part of the bellhousng form an Evo 4-6...

That would've been a cool swap and the 6g75 would've been easier since it had the spot already cast into the head for the cam sensor. Yeah mate I'm staying auto but it is also full built to cope with the extra power/torque. I thought about doing a manual swap but I daily this thing in sydney traffic, so I decided stay away from it haha

Thought i would post a small update, after a few weeks of being busy and hitting a couple of small hurdles. The car has been almost completely reassembled and fingers crossed back up and driving by the end of this week.

Hell yeah! That’s sick mate!
How hard was it in the end? Custom mounts? Or found stuff from other cars that worked?

It has been quite straight forward to be honest. So far all the mounts have had Mad polly inserts installed to allow for trimming and slight angles.

1x timing side mount magna with 10-11mm taken off each side

1x legnum rear roll stop and stock bracket

1x legnum gearbox mount

1x front magna roll stop bracket (modified) with stock legnum mount

What gearbox adaptor did you end up with and clutch/flywheel combination? Assume you went hydraulic release bearing and converted to push clutch?

I actually stuck with the Auto for the ease of conversion and because the box was built to hold more power. But to adapt the legnum box to the 6G, i just needed to swap the bellhousing over and add the vss to the 6G bellhousing

Car should've been driving tonight, but mistakes were made and a drill bit went through my new trans cooler. So once a replacement has been sorted i should be able to start driving it. Ps, the maf sensor is only there until i have sorted out my battery relocation.

Thanks mate. I bought it from a 2007 mitsubishi pajero that was being parted out. They were sold here from 2007 to 2011 or 2012 ?

First drive and It goes with such little effort! Apart from a few small issues, it went well i think.

Ohh I just assumed it was a USDM variant, rather than the local paj type. Still: top work.
