Mitsuibishi 4G63 2lt Turbo

[Craig – Absolute PACE]

One of the better options we have found for SL-R engines here in Aus is the Mitsubishi 4G63 2lt turbo. Fitted to Lancer Evo, Galant VR4 & Eclipse.

They are plentiful and relatively cheap here in Aus. Early 90's front-cuts start from AU$2500.

I've have personally inspected a front-cut & engines and it looks like a good match.

It's a clean looking engine with good reliability and plenty of aftermarket go-fast parts.

You just have to remove the AWD transfer box and plate over to convert to FWD.

Early 90's engines have 250HP from the factory. Mid to Late 90's have 275-300+HP. Torque is up to 275lb/ft for the later engines.

Fran(RCR) who is very responsive to customer requirements is busy setting up the chassis to accomodate the 4G63 for us.

We already have 3 x SL-R orders for Aus and all of them will be using the 4G63.

Looking at other engine options as well due to different levels of emissions compliance required. Hoping to be able to use something like the later model Honda engines where stricter emissions exist.

Craig,

You must have some engines we do not have in the USA.

I cannot seem to find any 4G63 1996 + Mitsubishi Lancer Evolution 4 engines here?

Looks like an excellent choice :thumb2:

[Gage]

Karlo, Try 2003 and up on those Motors. The Lancer Evolution only became available in the States recently. There was a celebration among sport compact car fans when it was released here. It made Sport Compact Car's best choice award or (whatever the award is called) at least one year, maybe two. I owned a 2006 Lancer Evolution RS, modified to make 275whp. While a little on the heavy side, they are incredible motors, built for boost...with aftermarket tuning solutions available.
The stock motor has sooo much power left un-used.

[Gage]

From Wikipedia:

The Lancer Evolution VIII was also the first Evolution to be sold in the United States,[5] spurred by the success of the Subaru Impreza WRX which had been released there just three years prior.[citation needed] The Evolution VIII found its true competition in the Subaru Impreza WRX STI model the same year as the Evolution VIII's US introduction. However, the internal components for the American versions were largely stripped-down versions of the specifications for the Japanese Lancer Evolution VIII. No US-spec Evolution model has active yaw control, including the 2006 Evolution IX. The American 2003 and 2004 GSRs are without the helical limited-slip front differential and 6-speed manual transmission. The 2004 US spec RS models, however, do have a front helical limited-slip differential. All 2003, 2004 and 2005 RS and GSR models have the Japanese Evolution VII's 5-speed transmission. The MR edition was introduced to the US in 2005, with ACD and the only model with a 6-speed transmission. The 2005 US spec RS and GSR have the ACD standard, and the front helical limited-slip differential is now standard on all models. The timing and tuning are also slightly lower than its Japanese counterpart, allowing it to adhere to the strict emissions regulations of the United States.

Most Evolution VIIIs have a carbon fiber rear spoiler with matching body-color endplates. All Evos have lightweight aluminum front fenders and hood. MR and RS editions have an aluminum roof. Additionally, MR Editions come equipped with 6-speed transmission, bilstein shocks, and factory optional BBS wheels.

The basic RS Edition does not come with an air conditioning system, power windows, locks and mirrors, an audio system, and map lamps. Also deleted was the Anti-lock braking system which came standard in other models..

[StatGSR]

stop lookin at evos, look at eclipses (in the US), any turbo eclipse from like 90+ has this motor in it. GST models come with a FWD version, GSX has AWD. and because they are typically broken garage queens, a full car can be found for pretty cheap...

http://en.wikipedia.org/wiki/Mitsubishi_Eclipse

but yea, i fear the crankwalk most of these motors have..... and iron blocks are lame...

[Craig – Absolute PACE]

Yeah, it only seems like the Eclipse was common in the USA.

It seems like the USA Eclipse models look to be quite down on power compared to the equivalent jap spec Lancer Evo & Galant VR-4.

Here in Australia we mainly have Lancer Evo.

Will let everyone know how they go. I expect they will provide plenty of FUN factor. :D

[Chadillac]

One of my friends had an old modified GS-T eclipse. Not as fast as my SR20DET but I was impressed none the less. From what I can remember the turbo on the eclipse felt like an on/off switch. It probably has to do a lot with how he modified it (I don't remember what he did do it), but that could get a little scary in a little SL-R. One minute you're crusing along, the next minute you're doing olympic style 720's with a triple back flip. Just be careful. That's big power for a little car.

[Craig – Absolute PACE]

Thanks, funny you mention the SR20DET, we looked seriously into that. Great engine. The Pulsar gtir black top version. Great motor, due to it's limited run it's just not as available as the 4G63.

Most of the initial SL-R orders are for track only cars here.

Going on the estimated finished weight, the owners know how much HP they need...I'm guessing around 450-500HP per tonne.

[Chadillac]

That's one of the greatest things about this car, you can put whatever engine in it you want. I really liked the SR20DET. The engine had 250,000 miles on it and was still going strong. I had to sell it because the car, not the engine was falling apart. Do you guys have the volkswagen 1.8T over there? That's a pretty nice engine and I think the boost is a little more gradual than the 4G63.

[Craig – Absolute PACE]

Don't know much about the vw 1.8lt turbo.

I'm certainly on the hunt for other engine options.

Customers can please themselves, but I at least need 1 engine option that they can use. And for 2 x states in Aus I don't have an engine they will pass emissions requirements yet.

[Craig – Absolute PACE]

Things are progressing well here in Aus with 4G63 engines.

We are currently preparing a 1991 USA Eclipse 4G63 AWD engine combo purchased by a customer for fitment to an SL-R.

It was purchased as a front cut.

Engine & gearbox removed and stripped of wiring harness etc. Gearbox removed from engine.

Engine & box cleaned.

Started work on the wiring harness etc.

Engine will be fitted with a few go fast bits. New ceramic clutch, new timing belt & tensioner(for insurance), new 16G turbo, new stainless exhaust manifold & dump pipe, aftermarket ecu.

It's going to be an insane ride.

I've also purchased another Eclipse 4G63 setup for the demo SL-R.

[Karlo]

"You just have to remove the AWD transfer box and plate over to convert to FWD."

Is this working as planned for the engine trans?

[Craig – Absolute PACE]

Yes, just plate over, you leave shaft etc all there. This is a common conversion. Apparently the 4G63T is a common fitment into fwd Lancers etc. In most cases they do not bother to do the whole AWD conversion apparently.

The 4G63T I have bought came with a FWD gearbox. So the 4G63T is available in both FWD & AWD formats.

[Saberwulfe]

I just sold 2 Eagle Talons (same as the Mitsubishi Eclipse) both with the 4G63 engine. The 1990 Talon TSI AWD I sold had just been dynoed at 304 WHP. The mods I installed to get it there totaled less than 1500 dollars. The Talon/Eclipse message board I belong to has several cars making over 600 WHP on stock internals, its a very strong engine with TONS of aftermarket support. Its also quite easy to work on. the Eclipse GST and Talon TSI were both front wheel drive so there would be no need to plate over the transfer case hole. The Eclipse GSX and Talon TSI AWD are the all wheel drive versions. Try and stick with the 1990 to 1994 6 bolt engine as the 95+ 7 bolt engine has a reputation of developing crankwalk (although I have owned 2 1995 TSI AWD's with no issues).

[Craig – Absolute PACE]

Thanks for the advice, definitely appreciated. I knew to stick with the 1st gen engines, they are the cheapest as well.

The AWD front-cuts seem to be much cheaper and more common for us to purchase compared to the FWD versions. Sounds like it is the exact opposite in your experience though.

Yeah, we think it's the best bang for buck engine for us to source in Australia and had RCR incorporate it into the standard engine line up for us.

The forum you mention is it the DSM Talk forum?

[Saberwulfe]

The message board I was referencing is a local DSM board Sovadsm.com (Southern Virginia DSM). I do actually frequent DSMtalk and DSMtuners quite often. A great source for new and used DSM parts (OEM and aftermarket) is dsmtrader.com its full of people parting out cars or selling off misc parts. I've owned 4 Eagle Talon TSI AWD's so I'm quite familiar with the drivetrain, it's kind of a hobby that keeps drawing me back in every few years. If you have any questions I'll be happy to help out. If I don't have the answer I know lots of guys who do!

[Craig – Absolute PACE]

Thanks mate, that's a kind offer. You would certainly know a lot more about them than we do.

The only hiccup we have experienced so far is that they have changed the location of the rear engine mount during the 1991 model. One engine we have has the rear mount on the block, the other engine has the rear mount on the gearbox bellhousing. Both are awd. On the cross member there is only one set of bolt holes on each, but you can see where the other mount would sit as there is flat area there.

If you don't mind can you let me know what you did to your engine to get to the 300rwhp mark?

[Saberwulfe]

Sure let me see if I can remember everything.

K&N FIPK
2g Mas sensor
Dejon Tool intake piping
Mitsubishi EVO III 16G turbo (ported)
Large no-name front mount intercooler
2g exhaust manifold (ported)
3" o2 housing with external dump
full 3" exhaust no catalytic converter
Magnaflow muffler 3" inlet 2 X 2 1/2" outlets
Walbro 255 LPH High Pressure in-tank fuel pump
Precision 550cc injectors
Aeromotive adjustable fuel pressure regulator
Keydiver Stage 3 EPROM, with stutterbox launch control, no lift shift, etc..
APEXi SAFC II
Joe P manual boost controller
Forge 1G BOV (blow off valve)

I added a Forced Performance "race" ceramic coated exhaust manifold later on. I had it tuned on an AWD Dynojet dyno were it made 304 AWHP @ 18PSI of boost. I could have bumped up the boost to 22PSI but the engine had 147,000 miles on it and I didn't want to kill it.

Ted IV

[Gage]

Man that all brings back memories. I took my first ride in a friends all wheel drive DSM and was sold. Then I bought an all wheel drive 4G63 Plymouth Laser, then the 91 Eagle Talon TSI. Into those went a BJ's ported cylinder head, aftermarket rods and pistons, TRE modified and built tranny, Taboo clutch rod, Force Performance Turbo, huge front mount intercooler, injectors, ported manifold.. AEM EMS, and on and on. I broke that car over and over, fixed it, sold it, and someone else drove it and broke it, and he sold it. Then that person fixed it, drove it, and broke it. I put more blood and hours into those cars than any other automotive project in my life. They completely burned me out on any normal car that has an engine bay wrapped around the engine. Then eventually I got an 06 Lancer Evolution and modified it just enough to stay reliable, Vishnu style to about 280whp. I sold that. Then the Atom. Sold that. Now I have a K24 engine for an SL-R in my garage.

I'm an addict.

[Craig – Absolute PACE]

Thanks Ted for that level of detail, much appreciated.

Sounds like you guys have really got into 4G63T engines in the past.

I'm looking forward to putting them into something just a tad lighter and a heap of fun. :coolnana:

[dwmtl1000s]

Are all the 4G63T engines of a iron block design? Do the trannys have a limited slip or posi in them, or be purchased aftermarket? Any real reputable retailers of aftermarket support for them that you may suggest? Anyone familier enough with them to know their weight minus the rear running gear?

I am not so familier with the 4G63 but there rep is well known to be great!

Sorry for such an oddball bunch of questions:run:

[Degeneerit]

Yes iron block, some come with lsd depending on year and model. Everyone makes parts for this engine, go with who you trust. Most complaints come from piston slap and others from crank walk due to poor design in the 7 bolt models.

[Degeneerit]

If you want to go cheep so your thinking about the 4g63 I recommend the srt4. I think its a better bang for the buck, comes stock with more power is easy to find with LOW MILLAGE which is not so easy on the 4g63 from 15 years ago and the srt4 has more potential imho. Oh yeah did I mention it sounds like a V8 without a cat.

[Craig – Absolute PACE]

Yeah, there are so many good engines choices all with their pros/cons.

We picked the 4G63T here in Aus as it's cheap, strong, reliable, plentiful and so many cheap go fast parts & knowledge for it.

Nothing else here compares. SRT4 are rare as hens teeth, Honda are expensive.

We haven't weighed one yet, it's something I would like to do.

We are also looking into aftermarket LSD options for 1st gen 4G63T.

[Saberwulfe]

Both Quaife and Kaaz make an LSD for the FWD DSM's. They are a bit pricey though.

Trans that do not come with LSD seem push the overall price of the Engine / trans package up when you add later.

[Craig – Absolute PACE]

Yeah, adding an LSD certainly does push the price up, but the 4G63T is still the best value option for us here.

Thanks Saberwulfe, the Kaaz unit looks to be the better choice for track work.

Kaaz DBM2010 1.5 way clutch type LSD US$832.50 rrp

[soon_2b_evil]

Craig what 4G63 motor are you using? Ive been thinking about doing a honda k20 motor but ive been messing around with 4g63 lately and I kinda like the turbo idea! Im thinking about using a 4g63t out of the evo8's.

[Craig – Absolute PACE]

We are using the early generation engines, actually using 1st gen Eclipse, Laser & Talon engines. What they call a 6 bolt. They are the strongest as well. We are just adding new go fast bits to get the power we require for the track - larger turbo, new exhust manifold/dump pipe, larger injectors, aftermarket ecu etc.

Evo I, II, II should use the same engines mounts. I say "should" as there are 2 different mount designs/locations used in the 1st gen engines. We are accomodating both.

From Evo IV onwards they revised the engine layout and reversed the orientation of the engine. We are currently looking into the later layout and also the layout of the later Aus Mitsubishi Lancer NA engines.

If you check this article, they indicate the different layout in the Evo IV: http://autospeed.com/cms/A_2752/article.html

[soon_2b_evil]

oh ok so your using a 1g 6bolt motor then. I just wanted to use the newer motor cause it looks alot cleaner! LOL I mean since its all going ot be hanging out at least you gotta look good! LOL

[Craig – Absolute PACE]

You are certainly right about making the engine look nice. The engine is basically the rear of the car.

The induction side is what you see, inlet manifold etc. The exhaust manifold & turbo are on the firewall side.

I'll start a build thread when I get a chance as the build has already started. No chassis yet, but the engine has been getting prepped.

[ozvenom]

As all ways shiny bits seem to find there way on to race engines dam waxers cant get away from them .I learnt a long time ago that blind does not make a car go faster i might make your sponsors happy but results are the ultimate goal.
If function is first and bling second then thats ok . This is not to say that a neat well thought out engine bay is bling its just practical.
oz.

[Degeneerit]

This car is the best example of form fallowing function I have ever seen. Anybody know if Fran still plans on including the rear fenders?

[soon_2b_evil]

got a question for you. Its kinda been borthering me. Since ur using a 4g63 and all. are u going to be daily driving this thing in the summer time? What do you think is going to happen when it starts to Rain? I mean everything is out in the open. so it would be the exhaust manifold and turbo will be getting wet and those parts are really HOT. would u have something to cover that side of the car up? i was watching some ATOM video and noticed how they had the
F1 intake cover thing. i was running up ideas on how i would do something like that. I wanted ot turbo a K24/k20 but then i was like man what would happen if i got caught outside in the rain? LOL I could see a supercharger cause its ran on belts so it couldnt be that bad but having a turbo running some HIGH heat and then rain falling onto it would only cuase some trouble?

[ozvenom]

That is a good question an engine cover has been disscused and ideas thrown around but the thing is that if you arare in the rain you will not be boosting hard so manifold temp will low also the manifold is behind the driver and would get very little rain on it droplets of rain would have allmost no effect on manifold temp because there is so little cooling effect from a rain drop but drive it thru a big puddle and that will be different massive cooling of the exhust could cause problems besides that fact that you would be drowned your self.
I would be more concerned about water getting in the ignition system stopping you in the rain thus everthing getting wet compounding the problem.
oz.

[Craig – Absolute PACE]

It's an area for consideration.

Rapid temperature changes would be the only area of concern in my opinion.

Yeah and as Ozvenom indicated, keeping moisture aware from the ignition system would be handy as well.

One thing you've got to keep in mind, is even with a factory turbo car, with enough rain, you still get some water onto the exhaust manifold area.

A rear engine cover would be great, but due to the different engine choices and sizes designing one is complex.

I mean i would use this for a sumer car and have some fun only when the suns out. North Carolina has some werid weather thats the reason i ask. Yeah the ignition system was something else i was concerned about too.
OBTW sorry im using a HONDA K24/k20 motor but since this was a turbo motor i decide to ask im not using a 4g63.

exacatly i would hate to be boostin around the city and a random thunderstrom decide to open up on me. Your right about the factory turbo car cause i used to have a EVO 8 and when i drove it it really didnt borther me much cause it had some vents. Now havin this motor WIDE open to the elements, kinda worries me going turbo. Im not using a 4g63 im using a Honda K24/k20 and the manifold and turbo would actually be in the back of the car open to everything.

[Craig – Absolute PACE]

Nothing wrong with a boosted Honda engine, nothing at all. :thumb2:

If it worries you, then it wouldn't be hard to make up a suitable top cover. Have the turbo behind the engine would be fairly protected from the elements anyway and if you want to add a bit of extra safety you would have a heatshield over it anyway.
