Based on Ben's experience trying to jam a 6a13TT into a magna.. it seems like it would be possible with some work.

I would however, ask why.. the 6a13TT is significantly better than the 6G :-)

No reason why can't be done. Is all but a bolt in operation but why throw out a doc tt motor for a soch na motor. Pretty pointless

If you go onto ozvr4 there are people who have done this. Usually with the dohc 6G72. I've only seen one thread and didn't read much into it.

Would the 6G DOHC be better on fuel, but still with decent power and torque?

The very small amount in fuel savings (if any) would be eaten up by the cost of the conversion, not to mention the loss of driving enjoyment of having less power and torque.

As per the above posters, I struggle to understand why you'd want to do this kind of conversion. In a conversion, you usually try to put a better motor in, not the other way around ;)

There was a version of the Legnum that was released with the standard 6G engine, but for whatever reason these non-turbo versions aren't allowed to be imported to Australia.
So I guess it could be done to a VR4 without too much trouble.

Just wondering, would this be a rooted VR4-tt engine being replaced... or just one with too high'er fuel costs... If so, what is happening to said VR4TT engine...

been na would that make it p plate legal

Not sure what the laws are in Vic but in NSW that car would still be illegal to drive as it has had an engine conversion.

Pointless excersise to put in 6G72/74 SOHC motor in place of the existing 6A13TT. If the said motor blew up, you can get used 6A13TT that crop up a fair bit at Mitsubishi/Jap import wreckers, heck, I've even seen them advertised on ebay & gumtree!!

Mum's got a Legnum and there is stuff all room in that engine bay. Not to mention that you'd have to swap over the ECU & probably need to get another wiring loom made up to match.
Unless you are going to town building a Hi-po Twin turbo 6G72/4/5 I personally think that you are seriously wasting your time & money.

well legnums did come out at one stage with a NA 6G72 which apparently which was the same motor as the magna ones and same orientation if I'm correct which was a 6G72 SOHC, so I don't see why you couldnt put one in providing you find the right box etc etc... and why not better off puting a 75 in it :D?

Chow, 6G75 with a twin turbo set up for the legnum ;-).

Seriously though, A DOHC 6A13TT is so much better than a SOHC 6G72. I just can't see the point, waste of a good car to put a boring (by comparison) engine in it.

IF i had the money, I'd have gone manual conversion along with a TT kit :)

Its actually a swap thats been done a bit overseas, search for galants in america, they use the 6g72 dohc and modify the twin turbo setup to work, leaving it a 6g72tt - basically a gto setup in the correct orientation for the legnum/galant. A guy in NZ has also done this swap with the 6g72 mivec. That said, replacing the vr4 engine with a 6g72/4/5 sohc and no turbo setup would be pretty pointless.

Even with a DOHC 6g72tt, that's a whole heap of money for a gain that could easily be had in an existing 6A13TT.
It's doubtful that the poster of this thread is looking to build an 800bhp street monster to justify swapping engines. Possibly the opposite & besides, you can build up a Forged 6A13TT to output more than enough power for any street/track application for a Legnum.

On that note, it would be good if the original poster of this thread could elaborate as to why he/she wants to put a (presumably SOHC G72/74) in the Legnum to begin with.

got any turbosfor sell

I have 4 spares

Sure can be done.. But the legnum/galant gear boxs wont fit a 6G engine.. So i'll have to get like Awd magna box

If you are going auto you would use a Magna box and have to then also go the Magna ECU to make it all work but then who would bother with all that work behind an auto so then the only option is to get the 6A13 box modified to fit the 6G74/5 engine

Hi guys well firstly HIim that said guy that did the Mivec conversion into a Legnum but it wasa 6a12 FTO Mivec that I used bolted upto a 4wd VR4 legnum. The reason for doing that conversion was a talk on a local forum of the VR-M legnums that were produced but weren't in nz etc. I once completed the swap then drove it for a bit and went back to vr4 6a13tt setup.

Now iv put a diamanté 2003 vr-x motor with a awd diamanté box I to a Legnum tight yes but it's in and working. Using USDM Engine mount.

Now the chassis I put this in is a ec5w Legnum 6a13(sohc)ST-R shell. Motor blew oil seal so I did it.
And get this. I am currently running and driving this car on the str loom too.

Now this is where my post in the other sub thread ties into this.

I'm in need of the Ecu pinouts of the vrx as the afm has more wires and a few differentiations so I am hoping to pin in the missing wires to be able to use the vrx afm.

And I'm getting a manual bell housing made up to bolt upto it as well so at the end ill have a 4wd setup that bolts to a 6G block. A rare luxury IMO and I intend to add snails to the said motor. And or i also plan on trying the 380 motor.

Thoughts please guys.

Hi, welcome to AMC

When I send over you housing I can send you over the wiring diagrams. You will find the missing wires are for the Barra Sensor, if you want I should be able to send you a spare harness as well so you can pick it apart and compare any differences there as well

So muchly appreciated dude. I'm just splitting the box housing this week and will get it sent,hopefully it fits in the bag to make shipping cheaper lol.
