Hi guys I own a magna wagon which i love the practicality of but i feel is lacking abit on the power side of things.
Which leads to my query, Seeing as the ralliart engine is the same platform as a regular magna engine i was wondering if anyone could tell me if i were to plug in a ralliart ecu and drop an engine in would it work without making changes to looms etc?
Thanks for your help

Not worth it IMO. Unless you have access to a Ralliart engine & ECU already and its cheap, you'd be better off going a 6G75 conversion.. Definitely more bang for buck.
There are many, many... many threads about the conversion.

Had a quick look into 3.8 but im looking for something drop in and go if possible the 3.8 only makes an extra 10nm and makes 5k less up top compared to a ralliart 3.5 but i definately havent ruled it out

6g75 is the way to go

Been looking for a while now cant seem to see a detailed post on the swap, is there a diy guide or something similar? cheers

The 3.8 has less power and a little bit more torque in the 380 compared to the ralliart because it was detuned for Euro 5 emissions. Put it into a magna without the restrictions and you will have a lot more power and torque. As for searching for threads on it, use Google: site:www.aussiemagna.com/forums 380 conversion

Yea the 380 is by far a better motor, it's around about a 190kw motor if swapped into a standard magna (due to heavy detuning in the 380, 3 cats, and a somewhat small intake snorkel). There is a fair bit more involving in getting it swapped over though.

So yea the RA engine is a direct swap in, IF you can find one. If you have TH- onwards ECU you can just flash it with the RA tune.

TWaGn, since you are in Victoria, you have a very capable person to do the conversion for you.
Madmagna owns Mits-Fix and has done 380 conversions.

There is a section of forum named Mits-Fix.

Fooz's old 380 made 163kw at the wheels when N/A with what was essentially extractors, exhaust and a tune. As has already been said, the exhaust is a major restriction on the 6G75 in the 380 but is not such an issue in the 3rd gens. The 6G75 is also far more commonly available than a Ralliart engine so it's the way to go.

Really not sure where these figures come from but comparing a Ralliart engine to a 6G75 is a bit like comparing a TM Magna to a 6G74. They are worlds apart

For starters, issues you will have
Ralliart ECU will have the requirement for a 5sp Auto (or manual if that is what you get) and they are different looms to the 4sp Auto
Your car most likely has no TCL, this will be an issue with the Rallairt ECU, again you will be having to change over many parts

In my opinion a 380 engine with 250k on it will still be better than a Ralliart with 150k on it. They are simply a better built engine, better technology went into materials and parts. Have seen 6G75's with over 400k on them still performing as well as the younger ones

Power, atw, straight into the car with no tune or other work you should expect around 140kw or there abouts. That is a raw drop in and dyno. Get the ECU tuned and then you can go up from there. There is one guy who is claiming 180kw but that in my opinion is utter BS. From the many I have done over the years from the very first years ago to the more current ones we are finding around the mid 150's ATW which is more than you need for the street. Now you get to add the upper 6G75 manifold once modded to fit and this can then go up.

If you are going to be replacing an engine in order to gain power (not just to freshen it up) you are mad if you go a Ralliart Engine unless you can get one for free or close to it. The ONLY reason our wagon loan car has a Ralliart engine in it was because it owed me nothing. Yes it goes ok BUT the 6G75 in the same car would go much better.

Mal, he is referring to stock factory figures.


Ralliart Magna:
Power = 180kW
Torque = 333Nm


380:
Power = 175kW which is 5kW less than ralliart
Torque = 343Nm which is 10Nm more than ralliart

Yeah I guess because Mal has done so many he's used to dropping a 380 engine in magnas and gets close to 10% more performance than those figures purely on the fact of the less restrictive intake, exhaust, and tune on the magnas.

In fact, the magna tunes are normally pretty rich under high low (acceleration (10:1)) so when you have a higher volumetricly efficient engine dropped in it brings the mixtures leaner for a lot more power than you would see out of your old 6G74 running the rich mixtures.

A 3.8 swap is in every way the best option, unless as Mal said a rarer ralliart motor becomes available for dirt cheap.

This is the sort of stuff i was looking for thanks alot, is it possible to keep cruise control when switching if i go to a manual box?

Certainly is, if you have an auto and you are going manual then you simply use the auto loom and ecu and patch in what you need for the manual

If yo have a manual ECU you need a Manual Loom, if you have an Auto ECU then you need an Auto loom

As a matter of strict technical accuracy, the Ralliart ROMs only have a couple of engine related maps different to the stock 6G74 which are easily copied into the standard ROM with the right equipment - assuming that you are talking about a reflashable ECU. There is nothing magical about the engine program code in the Ralliart ROMs - it is instruction for instruction identical with the contemporary "standard" ROM.
