Actually the closed deck design on these have to be run without coolant for prolonged periods to warp the heads. That and the ralliart was the last on the dyno on the day so it was cold when it went on, this was a warmup run, the 4-5 tuning runs afterwards the fan was turned on. Thanks anyway chief.

the 2.9 litre inline 6 with the 4speed GM trans was a nightmare for majority of users XD

These are just wrecker motors that are checked over, normally borescope the cylinders and check compression first. New water pump, timing gear, etc. Sometimes even the heads come off, check the head surfaces, new valve stem seals, clean up the intake and exhaust ports, new head gaskets etc.

Made them, quad projector LED D2's

Obviously I did, but off camera. You would never go in this deep without doing so. 15 minute job to ensure all valves are sealing 100%

My 380 is excellent on fuel, a great country car😅.

Owners love their Jeeps but are never satisfied with their engines. I wish to have a 6G73 in my KJ...hahaha

Theyd be slower

Not everything needs to be rwd ffs

Yep , worked at mitsu when they were being sold , the 4wd running gear and mystical turbo test mule was supposed to be coming through to rip the commodore and jump on at the time the turbo sedan segment with the commodore and xr6 . Unfortunately 12 months in , turbo mule development canned . 4wd with adjustable rear bias rumours followed with canning . All mechanics and sales guys were so excited for what maybe was to come . Mitsubishi announced the 380 . They missed the mark . Then pulled manufacturing all together . Australia’s 07 govt didn’t buy up Holden fleets despite having a hybrid available and went to bmw and Prius . The gurus above lost all tooling and manufacturing ability to private sale and international expansion . Mitsubishi opened it factory elsewhere with Holden and Ford Australia being shut down . The big 3 crumbled in months . The news reported it 24 months after . De-Industrlised with corruption sold to us as Green House progression . Now the market is flooded with hybrid depreciation .

😂😂😂😂😂😂😂😂😂

The cams from the ralliart 3.5 motors and the 380 3.8 engines are exactly the same. Some more lift and duration over the standard cams.

@@JBurford I was just being silly, love my 380.

+300cc to 3.8l better cams flat top pistons higher compression much larger valves = better flowing heads

Factory specs inside to outside in clockwise pattern. I forget the exact torque setting off the top of my head but it's the same for all of the Mitsubishi 6G family.

@@JBurford 108> 0 >108

There's really no need to use any big aftermarket parts unless you're planning forced induction, even then if you use good fuelling a stock engine will take it just fine. The only thing I would maybe recommend is cam gears and you can tune the stock cams for some more torque, that also leaves things open to tuning aftermarket cams if you got some down the track.

@@JBurford cool,i just wanted maby to make a little more rilable i want to build an overland rig out of it. Thanks for your feed back

@@DSERUR24did you ever do it ? I have an 06 and I’m thinking what I’ll do in future if my engine goes bad

@Scottadamsfan3481 hey how's it going, well I got mine non running, for 1k so I figured I can put up to 3k without loosing , but I had to put stop to the 03 till I fix my 98 that's my daily right now.. but I from research I don it's better just to rebuild than do swap for a eclipse Gt one, need to reprogram ECU for the mivec to work..

O and yes I did have bent valves looks like the owner before me never did maintenance and probably never changed the tensioner and it jumped time and bent valves, the back and pistons look fine thow.. looks like after machining everything already did the heads I'll need new cooling system , I'll probably do ARP head studs and MLS head gasquet if I do in the future put a centrifugal supercharger nothing crazy just 7 psi boost for extra power baby..

The main thing you should look for with the 380 is someone that can tune them to remove the triple cats and get a better intake snorkel on it. The 380s were detuned for the next step of euro emissions so they make less power than if you were to put them in a magna. The exhaust is heavily restricted and they came out with the same 4 cylinder intake snorkel as the lancers. Regular oil changes and proper oil level should keep the lifter tick down unless they are worn out. Not too bad of a job to replace them.

Lifter tick is either low oil, wrong oil, it worn lifters. Heavier valve springs are only to control valve float at higher rpm, you want the lightest valve spring that allows complete control over the valve at the rpm the engine is being used. If you use more, it increases wear and tear and reduces power

@@1616Rotor They don't have lifters.

@@1magnit lifter/tappets etc still work on the same principle of oil in them.

The butchers block and sand paper in the picture, just before the resurfacing clips :)

If you're not getting any compression in any cylinders you need to check the timing. If the timing it out it can cause no compression. Same with an overheated engine the heads can warp.

@@JBurford Hi, thanks for the tip i will check this weekend the timing belt, when i turn the key the motor only spins but no ignition, new fuel pump , i took a look at the valves when i opend the oil cap and the moved freely , was thinking the piston rings probably stuck and leting the compresion escape, but i will chek timing , bught the montero like that so i dont have a history of what might of hapend to it. Thank you for your help i apriciated.

Shortly. I've been flat out at work. I have a lot more time for this now though.
