V6 Scorpion

Post by dirtygalant »

hey guys thought I'ld chuck my car up here.

It's a 1980 Mitsubishi Eterna GSR Coupe, a jap import model which is mechanically the same as an early Starion having the same G63B ECI-Turbo engine, 5 speed box, IRS, LSD and four wheel vented discs. Being badged as an Eterna, it's the top spec model with electric windows front and rear, electric fender mounted mirrors, air con, lots of chimes for everything, and even an alarm clock!

This is how I got it in 2007 totally standard with only one previous NZ owner and 128k on the clock:

Image

Image

Image

Image


to cut a long story short, it basically has a 2.5" exhaust, VR-4 front mount intercooler, TC06 turbo and more boost. After that the suspension was just terrible and couldn't keep up, so I got some custom coilovers made up for it:

Image

Image

Image

along with giving the rest of the suspension an overhaul with new bushes and fresh paint:

Image

how it sits with SSR 16x7.5 and 16x8 rims:

Image

now at this stage the engine could no longer keep up with the handling of the car, so my plan all along was to go DOHC using these parts:

Image

Image

however.. I had not long ago purchased a jap import E39A Galant VR-4 Evolution with a 4G63 DOHC, and I figured one 4G63 DOHC is enough for me:

Image

Image

and my daily driver (another Galant) has a V6 MIVEC 6A12 engine which I've always admired, which I actually had to rebuild a year ago, and whilst the engine was out on the stand I thought long and hard about putting it into the Eterna instead of back into the Galant.. but after some research it was deemed easier to use a 6G72 as they come factory longitudinally mounted while the 6A12 never did and would have been a mission to setup engine mounts off the block, gearbox options, RWD water routing etc.

So fast forward a year while that thought was still in the back of my mind.. I pushed it to the front by getting these two engines:

Image

Image

top one being a 6G72 MIVEC 3L from a Diamante 30M, and the bottom one being a 6G72 TT 3L from a GTO/3000GT which had run a bearing. My plan is to use the MIVEC block and heads complete as the bottom end of the MIVEC engine is more or less the same as the GTO engine anyway, except with a higher compression ratio (10:1). To lower the compression ratio I'll use GTO headgaskets which are 1.5mm thick as opposed to the MIVEC gaskets which are 0.5mm thick.

So out came the oily G63B:

Image

and in goes the 6G72:

Image

and mounted using mounts from a V6 Pajero, who would have thought they completely bolted up and sat the engine in the right place at the right height:

Image

Where the engine is sitting there appears to be enough room to mount the TD04 turbos either side sitting snug to the block:

Image

Image

So that's about where I'm up to so far, as I have to overcome some hurdles, the main one finding a suitable gearbox for it - a 5 speed R5M31 from a MK V6 2WD Triton would be ideal.. except we don't have them locally here in NZ (strangely enough).. we either got Diesels in 2WD manual or V6s in auto 2WD, or V6 in 4WD manual. Otherwise I have a V6 Pajero bellhousing I could use to adapt to a Toyota W58 or R154 if need be. The other hurdles are making the sump clear the crossmember:

Image

making up a spacer for the inlet manifold so I can use the GTO upper manifold/plenum on MIVEC lower half to clear the taller MIVEC cylinder head:

Image

as well as making up some exhaust manifolds to sit the turbos where I want them, and also to track down some Pajero 3.0 or 3.5 V6 water pump/thermostat housing and crosspipe off the rear of the heads.

I've put the project on hold for a little bit while my bank account starts feeling healthy again but I hope to get stuck back into it within a few months time.

Mate absolutely beautiful props to u that is going to be one awesome car once its completed looking forward to hearing more just wondering how hard is it going to be to get that on the streets? wat are your laws like over there in nz will that be deemed road legal after all it will be a 3.0 v6 twin turbo in a 1140 kg car i dont think youd be able to get something like that registered here in australia.

It depends what state you are in. With NSW i figured out i can put in up to a 4.2 litre engine then supercharge or turbocharge it. Twin turbo 1UZFE anyone? :twisted:

here in NZ mods like engine conversions, brake upgrades, seat changes (on different/custom rails), major body mods have to be 'low volume certified'. So long as the work is done to a good standard and you abide by a bunch of rules set out, you should be fine. They have recently introduced the requirement for cat converters to be fitted to cars undergoing engine conversions which have originally had cat converters fitted, which unfortunately my car falls under that requirement. Once it's certed I could probably do away with the cat converter and hope I'm not pulled up about it at any future WOFs (RWCs I think for you guys).

My Eterna tips the scales at about 1290-1300kgs. It's a stretched Starion platform more or less, and early Starions weigh in the vicinity of 1250-1270kgs. Being an import it's full of electrics and excess sound deadening.

v-nice..


Bring your turbo's right up the top behind the head lights. Having the turbo's down so low is a real pain.

Look up a few pix of Turbo LS1's and 2's..

with the exhaust facing inwards on both.

Turbo LS1s and LS2s are 90deg V8s remember, this is a 60deg V6 we're talking about with plenty of room either side to fit a TD04 there, so why not put them there? It'll help with the weight balance and centre of gravity being down low and towards the firewall and also there will be a minimal amount of heavy exhaust piping and braces needed, seems pointless having the manifolds go to turbos all the way forward, only to have the exhaust gasses turn around and go back towards back of the car again.

LOL you think once u bolt it all together you wont need to pull it apart again? Mate this car will be in bits every3 days. Having the turbo's were u can see them, work on them, maintain them, Fix them < ECT is goin to be alot easyer then working with them down low.. you will need to run ur air filters up the top along with ur intercooler piping, The exhaust gasses are only goin to come out as quick as u put them in.. So y not put them in quicker??

Makes perfect sence to me, but it's your project, its not like i was making a suggestion..

Paahhh :D

I thought it was a pretty good find with the stock motor.
Then i saw the conversion you are going with.
Weap - on!

Good stuff man!!

Paahhh :D
You may need to pull your car apart every 3rd day but I don't intend on pulling mine apart that frequently :P I'll be using two TD04HL-15T turbos, fairly standard reliable Mitsubishi turbos which both will have an overhaul before fitting them. I've already mapped out the routing of the filtered air feed to the turbos and the intercooler piping and none of them is an issue, it's not much longer than the stock setup infact.

I'll be running a single air filter boxed off in its own partition in the same place as the original air box, with a Y pipe splitting it to each turbo, but before the Y pipe will be an inlet for the BOV to recirculate its air. The intake pipe to the far turbo will run about the same level as the cam gears in front of the engine, while the outlets to the intercooler will be down low and running in front of the engine about the same level as the crank pulley and joining at a Y pipe under the battery tray and then going though an Evo 6.5 intercooler, where it will come out the other end and enter back into the engine bay under the driver's side headlamp bucket where it makes a short dash to the throttlebody on the inlet manifold which will be extended down and pointing downwards a little bit. In that short section will be the BOV with its recirculating outlet not far from the inlet on the air filter Y pipe.

I do understand your concern with servicing the turbos but it's not like you service the turbos at every oil change, and with your proposed setup (which I did consider initially, but went in favour of my current plan) would have produced more weight, placed the weight balance further forward and increased the centre of gravity of the motor, not to mention the extra heat soak from the long exhaust manifolds and downpipes. Remember I'm talking about a pair of compact TD04s here not a pair of GT3040s I'm going to be showing off.

If it does come time to remove the turbos it will be a case of removing the piping and unbolting the four flange bolts which will be on top side of the manifold - no harder than removing the standard 4G63 SOHC turbo. I guess I'm used to working on transverse V6s with the rear turbo mounted between the head and close-by firewall, I feel my proposed setup will be quite simple and reasonably spaced out.

Mate that looks great, I am wanting to put a 6G72 into my Galant so I am looking forward to further updates.
I am lucky that I can just grab a RWD MK Triton and rip the motor and box complete.
Keep us up to date

Great project, I'm toying with the idea of maybe putting a 6G72 DOCH twin turbo in my GE Sigma (older 4 door sedan version of your Eterna). Please keep keeping us updated! Also check out my blog for loads of cool Sigma stuff...

Hi thanks for the kind words. Yep know about the GEs, they're the 3rd gen Galant while mine is the 4th gen.

had a look at your blog, looks cool. Ahh.. the whole Galant/Eterna/Sigma thing seems to confuse a few people. For the Japanese market, the E (symbol for Sigma) designated the sedan and wagon models, and none were actually badged with the word 'Sigma'. The A (lambda) symbol was for coupes only. For the 3rd gen (your GE shape) there were Galant-Eterna E and Galant-Eterna A models, kinda like how you could get a Corolla-Levin or a Corolla-Trueno. Then for the 4th gen shape (my shape), it was seperated into just Galant E or Galant A, or Eterna E or Eterna A.

Ok, I've contacted my local 4WD specialist and he told me they have quite a few Triton 2WD V6 5spd manual gearboxes for $800 each all with warranty and very good condition. BUT, he said none of them come with the bellhousing because the bellhousings on these gearboxes are very frail and break a lot and they sell them separatly. Can anyone else confirm this?

I guess that's good news for me, I was expecting that the 4WD especialist was going to quote me over $1000 for each gearbox and that they would be a lot more rare, but if the bellhousings really are a problem, then I'm not sure what I would do gearbox-wise.

I've always wanted a 3rotor turbo engine in my Sigma, but now a Mitsubishi twin turbo V6 seems quite a good high power alternative!

Ok, it's been a while between drinks sorta speak. I'm seriously thinking about a RWD 6G72 conversion now, but I'm going to do two different things: use a Ford C4 auto (using a Bill Hincher bell housing) and convert the engine from MPFi to a 350 Holey carb! My inspiration for the carby idea comes from the few Datsun 510/1600 from the USA that I've seen with VG30 engines running the 350 Holey carby! It looks and sounds awesome!

It's a shame we didn't see any progress on the original path of this thread. It showed a lot of promise. Has anyone seen a successfully transplanted mitsu V6 in any builds? Anyway, nobody would even pick that VG30 is a new school engine - it looks like a genuine retro style V6 (but where the hell did a carby manifold for it come from?) (H)

The very first V6 Nissan Laurel's ran VG30's were carby, like early 80's
I agree, shame this build is on hold. No I don't think I have seen anything actually completed running a retro fitted 6G7 series engine.

I was so excited about this engine swap I could hardly sleep last night! But I think I've hit a bit of a snag. Do any of the 6G72 engines have the ignition module built into the distribuitor or is it all built into the ECU? The problem is if the dizzy is run by the ECU, how am I going to run it if I use a carby instead of fuel injection?

Humm, interesting, apparently the ignition control modules are all separate to the ECU, this will be fun to wire up!

The ECU tells the "ignition module" when to fire, otherwise it will normally default to 10deg BTDC (like when you are setting the timing), at least that is the way most EDIS's (Electronic Distributor-less Ignition System) work, hence the reason for the Megajolt.

In Speedway over here we modify bellhousings and manifolds all the time. I'm on smartphone at the moment so can't post links but search google.nz for Mark Walford. He will make a bellhousing for anything and makes a heap of other trick bits. For Speedway we put carbs on injected ford and holden sixes and run ZF or ha boxes on the back of them in our Stockcars. Look for Walford on www.macgor.co.nz or www.trademe.co.nz
