Mitsubishi 6G75 Restoration - Part 2 

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

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.

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

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 :)

😂😂😂😂😂😂😂😂😂

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%

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