Mitsubishi 6G75 Restoration - Part 2

[@fuertelocoyyy]

un señor realmente impecable para trabajar, es realmente relajante su gestión...Saludos

[@GForceVRX]

Brilliant work mate, these are awesome motors

[@pcorf]

Would love this engine in my TJ. The original 6G74 is still pretty good though.

[@wagnermagalhaes00]

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

[@wiked3801]

The master stikes again

[@martinhadland5937]

Very nice man, well done.

Amigo una pregunta un bloque 6g75 3.8...le sirve a un motor mivec 6g75 3.8

[@xix_napalmer821]

I have this engine in my 380 VRX! Really nice. Do you think heavier valve springs would rid me of the lifter tick? I've heard it's not good for the cams. Also any recommendations on parts like pistons, rods, crank and cams? Perhaps individual intakes (kinda like an ITB if that makes sense, I don't know much about those but they look cool!)

[@JBurford]

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.

[@1616Rotor]

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

[@1magnit]

@@1616Rotor They don't have lifters.

[@1616Rotor]

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

[@crdbr]

Is this the 6G75 MIVEC? Where can you find Rocker Arms for this motor? I have searched everywhere without any luck.

[@davidw.5185]

Looks almost brand new again. Great work! How many miles did the motor have? My 06 Eclipse GT has 73k miles. Still runs strong. Just curious. Thx!

[@JBurford]

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.

[@DSERUR24]

I will start my cleaning and rebuilding of my 2003 monter 6g75 if I have bent valves or damaged pistons do you recommend any aftermarket parts to upgrade? and any tips for rebuilding the motor

[@JBurford]

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.

[@DSERUR24]

@@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

[@Scottadamsfan3481]

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

[@DSERUR24]

@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..

[@DSERUR24]

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..

[@محمدالخروصي-ط3ب]

How much did you bording the head of the engine

[@1616Rotor]

How did you get the head surfaces so clean?

[@JBurford]

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

[@kierenalvarez]

Love it!

[@newtonkline5341]

why u no lap valves? its so easy and free

[@JBurford]

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%

[@محمدالخروصي-ط3ب]

What is the difference between 6g74 and 6g75

[@JBurford]

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

[@matiasshenriche-elalaster1756]

can I send my Mitsu Endeavor to you :D

[@1616Rotor]

Juicy AF

[@perpetualgrin5804]

I've driven over 1600 km never exceeding 2000 rpm in my 380. You don't have to rev them.

[@neilasd3043]

😂😂😂😂😂😂😂😂😂

[@edwardv8216]

My 6G75 is a little different then that one
