Evo motor?

[TTV6VR4]

Has anyone thought of putting an 4G63 evo motor into their VR4, instead of the 6A13TT???.

[jakester]

what benefits would you get??, would that have enough grunt to pull a 1700Kg monster along?

[AllBeItMine]

an evo 6-7-8-9 motor has more torque and more power than a 6A13TT so they would pull it just fine.

they are also cheaper and easier to modify

stronger overall and respond better to modifications

and their aftermarket support is obviously a lot greater.

its also a reasonable easy modification to fit one.

other than that - i can't think of any benefits... :inquisiti

/Hmmm what was that green one at santa pod running :inquisiti i'm sure the standard fwd autobox would stand it

Why not just buy an EVO?

[Nick Mann]

Why not just buy an EVO?

Good point, well made. :smug:

[bradc]

I agree, if I wanted a 2.0L then I would have bought an evo in the first place.

[AllBeItMine]

i bought my galant as a compromise because i wanted an EVO but couldn't justify the extra 15k at the time.

[dickytim]

I have thought about it if I blew my engine it would be a good option for all the reasons ABIM has suggested

[TTV6VR4]

But its a different story if the Evo engine that you put in was like 800HP, no one would be complaining then.

[Kieran]

Hmmm.... With a 4-banger surely you'd loose that smoothness and the flat, progressive power delivery that defines the VR-4? :inquisiti

[OSiRiS]

Same here :)

[AllBeItMine]

boost comes in about 700rpm later in an evo... but it will rev freely past 7500rpm in standard form. and once in the power band - there is no lack of smooth power delivery.

until you have taken one for a drive - you can't really compare.

i would say the *only* downside to owning a late model evo over a vr4 is the slightly smaller cabin... but the car itself feels great.

[OSiRiS]

I had an old skool Evo powered VR4 when I was 15. Had it up until I was 18 then sold it and bought my Legnum VR4. I could have purchased an Evo however I wanted to be different to my mates which majority of them have Evos. So I bought myself the rarest VR4 of all, a Super VR4 ;)

And to be even different, yes if I some how manage to kill my 6A13TT I will keep the shell and transplant a 4G63 back into it.

[pezza]

I reckon it could be a great project... I know you could get an evo but would be interesting to have a legnum sized vehicle and also have some of that brute force power in it.. People on here have always talked about evo gearbox swap, so why not an engine swap??

Not sure how the tip tranny would behave and feel like with that engine (how was the EVO GTA?) but maybe with extra weight of that leggie it may not be a neck snapping as the lighter evo..

Think of the amount of extra space in the engine bay also for work and upgrades... especially space for turbo etc ... :thumbsup:

I wonder who would be the first on here to try that... sounds like a loada work tho /Hmmm

[dickytim]

I really think it would be a ralitively simple change over, you can already get a galant with the evo motor in it and 4wd, so the parts to do it should be easy enough to get ie engine mounts etc, then change the computer over, the computers on the VR4 aren't really linked so it should be fairly strait forward.

[AllBeItMine]

and you can buy an evo7 motor with everything for $2800

Which Galant are you talking about here?

[dickytim]

sorry let me re phrase, you can get a 4WD galant with a 4G63 in it.

I was refering to 1996-2004 galant

[bradc]

it obviously isn't a 4G63T though, maybe that would make a differance to things like engine mounts.

Evo GTA is detuned to 260ps.

/pan hehe I guess, there must be some other reasons to explain why not a single EVO (tried with several 3,4,6,7,8) could keep up with VR-4... there is only one EVO in our city that I didn't even bother to go up against (1/4 time is 11,85).

Yep they can't drive :P

[ako]

In my opinion its the single most logical thing to do with the 6a13TT - ditch it for a 4G63 - if you're after bulk power.

For alllllllll the reasons ABIM has mentioned. Its a stronger, much more modifiable and supported engine in the aftermarket - personally I don't care about being "different", just being fast :evil2:

[Rossco Type-S]

Am I correct in thinking that the chasis on a normal galant is not a tough as a VR4? I am sure that I read that ralliart were given the task of toughening up the chasis for an 8g galant. If that is true, simply transplanting a 4G63T into the 4wd Galant VRG would not achieve the same results as transplanting it into a VR4.

Also, brakes and suspension would be weaker.

[dickytim]

In all honesty if I were gonig to do this I would be getting a wrecked Evo and taking the engine, gearbox, brakes and all, but hey this is all hypothetical.

[jasevr4]

Sorry to dig this one up, but I am interested in this.

Mainly because I want a wagon (Legnum ;) and I am in Australia, so aftermarket and replacement parts for the 6a13 are pretty much non existant.

What Rossco asked seems correct. Surely the chassis wouldn't be as strong on the non VR4 Galants/Legnums? I'm not too concerned about suspension as I would be upgrading the suspension and brakes.

What engine mounts would fit? I know the Legnum came as an "ST", which came with a 4g93 - are these the same as a 4g63?

Any help that could be given would be greatly appreciated. :D

[OSiRiS]

4G93 is 1.8L
4G63 is 2.0L

[jasevr4]

4G93 is 1.8L
4G63 is 2.0L


Whoops, sorry I should have been more specific. (Wrote that when I was half asleep).

I understand that the 4G93 is the 1.8L; is it a turbo model? Are they the same engine as the 4G63 as far as the exterior is concerned? (Bolt holes, shape, etc - would it bolt in?)

[OSiRiS]

Completely different motors.

You can get a 4G93 turbo and non-turbo. T usually indicates turbo.

e.g. 4G93T -1.8L turbo

e.g. 4G63T -2.0L turbo

e.g. 6A13TT -2.5L twin turbo

[jasevr4]

So (for example) an Evo 7 4G63T isn't going to bolt into a "Legnum ST" with a 4G93?

Nothing is going to bolt in.

You will have to fabricate engine mounts etc. Make sure the engine mates up to the gearbox properly.

Wiring loom.

Those are just the majors. There will be other small things but I won't delve too much into it...

I take it you have looked into it before?

And I take it the engine in the "ST" is the "old shape" 4G93 then?

[OSiRiS]

In all honesty no I haven't looked into it before.

However common sense and Mitsubishi knowledge leads me to draw these answers for you.

What exactly do you mean by old shape 4G93?

Are you referring to how Mitsubishi mirrored the 4G63 engine 180 degrees in the engine bay? (Comparing Evo 1, 2, 3 to Evo 4, 5, 6 and beyond) I beleive this has something to do with how the gearbox is mounted in the early evos compared to the later evos.

[jasevr4]

Sorry - to be honest I am an early model Mitsubishi person so I don't know the correct terminology. I previously owned an E39A VR4.

You are correct, I am referring to how they mirrored the engine.

I guess my logic is that if you can bolt an Evo 1/2/3 (or VR4) 4G63 into an Australian delivered "Lancer GSR" with a 4G64, you should be able to do the same on a Legnum ST with a mirrored 4G64 and an Evo 4-9 4G63.

That may be possible, you will just have to sort out the engine eletrical side of things, ECU etc. and how the engine mates up to the transmission, double check engine mounts and other various little things.

As you can imagine, there won't be too many definate answers as no-one as far as I'm aware has put a 4G63 into a ST. However a FEW people have done 4G63 into a 8G VR4.

[jasevr4]

For sure.. Thats probably the hardest decision - whether I'm best off starting with an ST or a VR4.

Electricals would be a decent job, not sure I'd be best off trying to stick with the stock ECU or just going aftermarket from the start..

I have read the threads on thegalantcenter.net about a 4G63 into an 8G, but I'm also not sure on what differences there are with LHD to RHD.

[conaboy]

Having a think about the 4g63 into the 8g galant VR4.

Have been told my crankshaft is fecked and NO-ONE wants anything to do with it. Four garages have now knocked me back to investigate further (strip the engine)

Weighing up my options at the moment, have spoke to Mo about a straight engine swap and am seriously considering this route. But.....

I know what im like and in the long run want MORE POWER, ideally around the 400bhp mark. Can people give me as much info as possible about how viable this option is. Bearing in mind I cant undertake the work myself but will be paying a garage to do it. Will all the electrical work and possible probelms make this a stupid idea???

All advise and info welcome

[bradc]

400hp will be just about possible without changing the turbos, but you will need to go with an ecu, fuel pump, intercooler, etc etc.

[zyrofillica]

Hmm how come a 2.0l engine can outperform a 2.5l engine? Is the stock turbo on an EVO much bigger? 4 cyc vs 6? is the 4g63 really so much more better than a VR4 one?:5shots:

Is there no plus point for the 2.5l Twin turbo compared to the 4g63T? :-ished:

[bradc]

The turbo in the evo can do about 400hp without an upgrade, but they are a lot more laggy and have very little power at the lower end of the rev range compared to a 6a13tt.

The 6a13tt is definately a lot better as a daily driver, it is just limited by it's turbos if you're trying to make big power.

[conaboy]

Decided its not worth the hassle pursuing the Evo engine transplant.

Mo is replacing the engine with another from a VR4. Have most of the things I think I need to see around 350 bhp (hopefully) anyway.

[pezza]

Will be great when someone off here tries this... I reckon it will be some beast
but a lot a work to do

You're forgetting that both engines put out 206kW at the flywheel from the factory.

Then you bolt on the aftermarket parts to unleash the power.

Now the simple design layout of the 4G63 engine has allowed aftermarket performance part manufacturers to create such things as exhaust manifolds, bolt on intercooler piping upgrades, fuel rails, bolt on turbo upgrades, bolt on ECUs etc. not to mention the ease of changing simple things like spark plugs, rocker cover gaskets etc. etc.

When it comes to the 6A13TT everything is custom. Because it isn't classed as a performance engine as such, and not many in comparison to the 4G63 are used in competition purposes, aftermarket performance part manufacturers probably opted not to research and devlop parts for the 6A13TT engine due to the lack of space in the engine bay and the lack of consumer market for them.

A 6A13TT can go as fast as a 4G63, if not faster and more powerful. You just don't have the off the shelf items the 4G63 has and you will have to go custom for pretty much everything you do.

[bradc]

You're dead right there dude.

What I find annoying is that people say evo's are easier to modify because of all the bolt on parts, but all of the bolt on parts from major manufacturers are very very expensive, and you could make your own custom parts for less than that.

I think that if we could get a TD04 kit sorted with manifolds and everything it would be a very easy upgrade to about 450hp.
