Hi all,

I'm a newbie to the site and somewhat a newbie to Mitsubishi's in general.

As a newbie, I've been running around all over the net trying to gather info on the different parts that are interchangable between the the van models and cars etc.

I'd like to make a PDF file for all those out there like me trying to figure out what can be done and make some sort of educated guess as to the cost and the effort ALL the options will entail.

There's so much miss-information and generalising going on all over the net mostly due to the fact that most people who own a van don't want to modify it. My hope is that we can gather all the info and put it in one place for everyone.

So, I guess the questions are:

* What doner engines will fit the early L300's (Bolt in swap)
* What doner engines will fit the early L300's (Mild Modifications required)

* What doner engines will fit the Later L300's (Bolt in swap)
* What doner engines will fit the early L300's (Mild Modifications required)

* Diffs??? LSD?? from what?? to what??

* Gearbox's

* Drum brake to disk brake conversions accross all models??

I have specific questions in regard to my own Vans. I have two 1988 and one 1993 Express's and I don't really think that the 2.0 litre is all that underpowered - potentionally. I think it's mostly miss-managed at the factory. Are there Heads off other engines that are a bolt on swap? (I say this after driving 2 litre toyota's for years - much stronger torque and speed)

Can I obtain an EFI Head and Manifold, Loom and ECU and bolt it on? Maybe from a Magna or the like. I know that there are Import EFI's available from Japan, what are they from?

What about stroking the 2.0l using components from similar engines? Crank, Rods, etc?

Hope this gets the ball rolling... It'd be nice to sit down and start having a good think about all the different options available. Basically, after doing a lot with cars and being able to hit a forum and have a good idea of what I COULD do to it within 15 minutes, I'd like to get the same fealing going here.

Thanks for reading, hope you will all start listing stuff off and throwing in some details. I'd like to get a few things up so I can start on the PDF and update it is it goes.

Ok.

I'll start the list off with some of the research I've done.

Below is some information and some guess work on engines, heads, diffs and gearboxs that will either swap or bolt on to the L300 series. :thumbsup:

As this is all just research from the web, I'd like to state for those looking to perform any modifications that this is NOT %100 correct information and I urge all to talk to someone who knows what the hell they are doing. It could be a very expensive mistake. Use the information provided at your own risk.

Engines:

Express/Starwagon (4g64)
o Single Over Head Cam (EFI/Carby) (2.4 liters)
Galant (4g63)
o Single Over Head Cam (EFI)
o Dual Over Head Cam (EFI)
o Dual Over Head Cam – Turbo (Cyclone engine) (EFI
Cordia (4g63)
o Single Over Head Cam (EFI)
Starion (4g63 + 4g54)
o Single Over Head Cam (EFI???)
Lancer (Lancer EVO) (4g63)
o Dual Over Head Cam (EFI)
Sigma (4g54) – Automatic
o Single Over Head Cam (2.6 Litre) (Carby)
Magna - (4g54) Astron 1, 2
o Single Over Head Cam (EFI + Carby)

As far as I’m aware, all the engines above will be a bolt for bolt swap to the current mounts and gearboxs in a 2WD L300. The 4g54 requires minor modifications to the radiator as it needs to be pushed forward approximately one inch for fan clearance if a bolt on fan is used. (It also requires the old flywheel/clutch from the 2 liter???)

* Sump may need modification
* Manifold may need modification
* Plenum may need modification
* Timing Cover may need modification (Parts available from Sigma/Scorpian 4g54)
* Water Pump may need replacing with sigma astrons

Heads:

All 4g63 heads are interchangable. All water Galleries line up and the same with the bolt patterns.

However, the timing gear that run the heads will be different between each but I would assume that the timing gears and associated parts would be interchangable between each of the engines.

Gearboxs:

The standard 2 liter gearbox will bolt straight onto the back of all 4g63 and 4g54 engines with the exception of the Sigma Manuals. The Sigma's have a 320mm spacing for the two top engine bolt holes versus 310mm(?) as standard.

(Unsure of the boxs in 1.6, 1.8 and 2.4 models.)

Diffs:

It's possible, though still a guess, that the Triton LSD diff will fit into an L300 bolt for bolt or with little modification. I've read uncomfirmed reports of someone using the rear differential in a 4x4 but I am unaware of any differences in the diffs between 4x4 and RWD.

I would assume that the prop shaft between the 4x4 and the 2WD L300's would be different lengths as the 4x4 has a transfer box. Someone is sure to correct me here.


That's a summary of it so far. Please please please feel free to correct any errors and point me, and everone else in the right direction. :grin:

Also feel free to add to the list if I've missed any models or parts.

Ben.

Have A look at some of the other posts in this forum there is some info there check out member Ken Landy he has done some replants & has some great tips there is a reply from Ken to the post titled decison time with some of this info

Hi Benster
This is a really great idea trying to gather this info we really need to get other members involved in this forum to make it work. Members Ken Landy & anth seem to have quiet a bit of knowledge on interchangeable engines & the pitfalls of trying to make it work. I have fitted a 2.6 fuel injected motor from a TR magna (1994 model) into my 1985 l300 4x4 van. As I run dual fuel I decided not to use the injection gear (easier to hook up through carby with my system) Anyway probs I encountered
magna water pump now runs at back of motor longer radiator hose needed original sump was badly cracked so I used the magna had to dent it at front to clear front diff pumpkin
to run carby I needed inlet manifold & carby from TP magna (still running efi head bigger inlet ports)
2litre flywheel & clutch used
my starter motor was a bit tired now run a triton 2.6 starter
magnas run an electric fan so I used on front of radiator gives more clearance
I am about to do it all again haven't decided on motor yet refer decision time in this forum
hope this helps keep the ball running on the data collecting topic

Hi

I think its a good idea, I have spent 6 months trying to piece a half decent 4g63 together and have given up on the idea.

I have tried the head off the 1800cc engines from the earlier Delica model, straight bolt on but ran like ****.

At the moment I have a 2.4 out of a sportpac in my L300, mounts are the same as you might expect but there are two versions of the 2.4, narrow and wide block. I unfortunately ended up with a wide block which doesnt fit my gearbox from the 4g63. So now I have the misfortune of trying to track down a wide block gearbox with a cable clutch assembly. My last motor died because of the block, head is in excellent condition, crack tested etc. I have thought about getting a 4g63 block but the 2L is too gutless for my liking.

From what i have seen, the heads that are not cyclone have a larger, rounder cavity for the top of the cylinder whereas the cyclone heads have a more oval shape and have a smaller area. Also the non cyclone heads have that second valve-thingy on the intake side which I have no idea what its for. Sorry I dont know what they are called.

For anyone wanting to do the conversion to the 4g64, if you get the loom and computer from a sportpac, the loom fits right in to the same place as the standard loom, its pretty easy, but make sure you get the tank from the sportpac because the tank has a little resorvoir where the fuel pump fits in, this is missing from the 2L petrol tank. Dont forget the fuel lines, they are different as well

Dont take my spiel as gospel, I could be wrong but it is what I have come across in the last six months. I have owned my L300 for 7months and driven it for one month out of six but I wont give up till the **** on the road again

thanks

Hi
this can be all very frustrating from what I can work out with the 2.6 conversion most donor motors came from sigma's & there was a different block automatic was narrower but bolts upto the original 2 litre bellhousing maybe thats the same with your 2.4 litre maybe you have a manual block but need a auto if we can all work together & get this info recorded it will be great

Well I have sourced a sportpac gearbox which is a manual five speed, distance between top holes is 130mm. My only concern now is the size of the drive shaft ie length and spline fit. Hopefully the gearbox isnt physically bigger.

Apparently the 4g64 in a sportpac is a wide block whether its manual or auto. I hope the starter motor is the same.

Will keep you posted on developments.

Hey buddy ive got the same problem with fitting my 4G63 engine into my 1990 sports pac. it dosnt fit into the standard gear box. did you end up finding a gear box that fit and bolt on to chassis? did you come across anymore problems after the gear box? could yah please get back to me. cheers

Okay I've got some Express VAN info for ya.

L300 diff can be replaced with a Scorpion one. Lowers the final drive ratio to a much better option than the 4.6 they give standard. Diesel final diff ratio is lower too. Plus there are LSD option scorpion diff out there too! I've been searching for 6 months now and still no luck....

Auto to manuals......doesnt work, if its 2.0L or 2.4. For some weird reason Mitsubishi use different generation engines and stud patterns on all autos and manuals. Its a real pain in the a*se.

2.4 8valve and 2.4 16 valve models. Again one is a gen1 and the other a gen2. Boxes are not interchangable. Heads are not interchangeable either. However if you have the 2.4 16v motor (gen 2 engine) you can bolt the twin cam 16v head straight on from the Evo or even from the Hyundi Sonata. 2.4 EFI 16v manuals produce 100bhp at the wheels, 2.4 EFI 8v produce 75bhp at the wheels.


Heads on the 2.0L are basically Cordia heads. Means Cams, lifters are all interchangeable.

Also note the 4G63 van motor is basically an EVO bottom end. Means its strong very strong.....300% power increase over stock power is not uncommon without any failures. We've tested this many times :grin:

Cool, getting all this info together is a great idea. Ive been searching to find the easiest way to turbo my 2.0 carby 16v express van. however all manifolds and turbos come from other cars. ive asked many people as I dont really want to fabricate the parts myself and all i want is 7psi to overtake. No one seems to know what model to order off.

So far im thinking I should be able to use an EVO 3 turbo manifold and turn the turbo 180 degrees on the flange. This will aim the exhaust back and the intake forward. Then all i have to to is get the exhaust hooked back up and fabricate a mount for a 48mm dellorto, and a connecting pipe back to the inlet. I intend to piss all the vaccum crap off as I dont think any cop is gonna wanna lift the seats to check :P

If anyone can confirm my idea it would make my day.

Only other idea is to flat out change entire driveline to VS V6 - dont wanna do that just yet

not forgetting the 2lt starwagon head 4g63 whats interchanged? and is this head also change able with the evo
