Outside the box thinking!!!
So i've been doing some research about the 8A80 from the Mitsubishi Proudia, Dignity and Hyundai Equus. It was a joint venture between Mitsubishi and Hyundai. The Proudia and Dignity were only in production for about 15 months in Japan starting from 99' and only about 2000 cars were ever produced. However, the Hyundai Equus which was basically a rebadged version of the Proudia was quite popular in Korea. and was sold with a 6G74 (3.0L, 3.5L) and the 8A80 engine as well.
The 8A80 Engine which i'm really interested in was modified by Hyundai as at the time Premium unleaded fuel wasn't easily available in Korea and they had a lot of engine issues due to this! so they changed the Gasoline Direct Injection (GDI) to a Multi Point Injection (MPI) system similar to what our 6A13tt runs, with what i can assume was individual injectors per cylinder. I'd say that's the engine you'd want over the GDI one.
Important info about the engine-
weight- apparently only 10kgs heavier than a 6G74 at 230kgs. Due to an Alloy Block and Alloy heads.
only 50mm longer than a 6G74. I assume this is length as in from strut tower to strut tower as it's an east west engine.
DOHC
Compression Ratio- 10.7:1
They run an IVECS II gearbox similar to the 6G74 and correct me if I'm wrong similar to an Auto Leggy?
The Engine Orientation is very similar to our stock engine- orientation as far as location of timing belts, alternator, Power steering pump, coolant lines, intake manifold, air box etc.
I HAVE NO IDEA IF THIS ENGINE WILL EVEN FIT IN OUR ENGINE BAY!!!!
This engine is designed to move around a curb weight car of 1950kgs. it's got some decent power!
Through import monster- for a half cut before you buy the car from the auctions- you're looking at $2800 which is the price for cutting the car, packing it, shipping it to Australia and import tax. then the price of the car at auction. you can see previously sold cars they have gone for $450-$600 a car. (not to bad IMO) so you'd be looking at a landed price of a half cut of about $3400-$3800.
That's a fair bit of money, however that's only one quote for a price delivered- its also only going to be a GDI model. possibly getting the MPI from Korea would be a better option, however it means the engine will have been run on dodgier fuel during its life time. but will have an injector per cylinder which will make upgrading everything a lot easier I feel.
What to do if you got one of these engines into AU (Multi point Injection ideally)
use a half cut or front end of a parted out leggy or galant and see if it'll fit in.
If it fits- then subframe modification- use leggy one or one that comes with front cut.
engine mounts- uses 4 engine mounts, I can assume in similar position to stock ones- would need some custom brackets chances are and the decide what engine mounts to use. (don't forget although it's a big V8 it's not that much heavier than ours, I'm unsure as to our stock engine weight but i'd assume it is similar if not more than a 6g74 due to turbos and all the extra stuff.)
Then comes driveline issues- will the driveshafts sit in the right spot? what gearbox will you run. you'd really really want a manual- which would involve a custom housing i'm guessing and a strong gearbox for sure.
AWD? could you get it to mount up a stock leggy or evo or awd system with transfer case etc?? I dont know!
ECU- guessing haltec would be the only way to go or something similar- I'd be keen on E85/Flex for this engine due to the fuel properties helping with power and knock prevention.
non turbo???- set of cams in it and E85 it would be a pretty formidable N/A engine possibly?
Turbo??- not good compression for a turbo- could run a low boost turbo set up for some extra power or, change pistons or space the heads to lower compression...
There's obviously lots more to consider. But just a summary of what I've thought of from the top of my head.
Cons- there's a lot-
Price
Time
Fitment?
Why would you do this in the first place?? for me- it's a completely untested platform and that appeals to me hugely, and you're keeping it in the family and putting a Mitsubishi engine in a mitsubishi.
I think this thing if it was in a leggy and fitted and worked etc would be a lovely car to drive. would have a lot of driveable power if you had the driveline to support it.
If you find anything else out about this engine please let me know! I can't find out if it comes with factory forged pistons or rods etc, which would be nice to know and if the heads are held down with some really solid bolts etc. Hope you enjoy the read!
