🤔 What's so special about 4G63? | TECHNICALLY SPEAKING

[@haltech]

You've asked for it and here it is - a lowdown and a teardown of Mitsubishi's famous 4G63t. What engine would you like us to feature next? Let us know in the comments section:) ------------ Often voted alongside of Honda’s K-series and Nissan’s SR20 as the best import four cylinder engine of all times, Mitsubishi’s 4G63 is also one of the favourites within the JDM tuning and racing community. Hitting the spotlight in 1980s powering Mitsubishi’s World Rally Championship program Evolutions with the legendary Tommi Makinen, the 4G63s quickly reached a cult status among import enthusiasts. Quickly adapted for drag racing the 4G63 is now a common sight on strips around the world with Haltech heroes like Aaron Gregory and Devin Schultz pushing their 4G63T powered machines to consistent 7 and 8 second ¼ mile times at over 200mph! In this video we dig deep into the innards of this power plant to see what makes it one of the most revered four cylinders on the planet.

I love the 4G63 Platform and all of my Haltech hardware. The 4G63 is really an incredible engine. Simple to work on, simple to build, very strong and very forgiving at relatively high HP numbers. The fact that a 4 cyl. In an AWD car is almost in the 6 second zone, is absolutely incredible.

Slight mistake: The 4G63T was actually first used in the Mitsubishi Lancer EX 2000 Turbo back in the era of Group 4 rally in the 1981 championship, carrying the car to a third place finish in the 1982 Thousand Lakes Rally. The engine was then used in the Group B Mitsubishi Starion 4WD Rally, which would become the platform for the Galant VR-4

6 bolt engines don't have a full girdle, but 'suitcase handles' that tie the first and last pair of main caps together. Full girdles are available from the aftermarket, which is a good idea if you are building something like a high power stroker.

8:40 not only turned around but mirrored. The cams point the other way, but the exhaust manifold is still towards the front of the car. 21:53 If the engine is out its better to just get a balancer delete kit. And if you really want to keep it, replace the belt. Remember, the balancer is spinning twice as fast as the engine rpm, so it it could potentially rip at 15000rpm and break the cam belt or make it jump a cog potentially damaging the engine. Remember that you cant just remove them but the lubrication of the shafts need to be blocked using a readily availabe kit.

[@markcozzie]

And then spin the bearings in the block or you'll lose oil pressure 👍

[@brycefujita2117]

The heads are different but they are not mirrored. The oil pump sits to the right of the crank and the balance shaft sits to the left of the crank. Doesn't matter if its a 1g, 2g, or evo. I have a 6 bolt, 7 bolt, and an evo block sitting in my garage 😅

@@brycefujita2117 Definitely ALOT wrong info in this vlog 👍 .

So, if the engine is turned around 180 degrees, but the exhaust is still at the front and the intake on the back, how can the head not be reversed? Doesn’t seem logical

[@david929190]

Magnus motorsports went into the crank walk issue and had suggested that it's the result of the revised second generation oil squirters sticking open. Since the revised squirters draw right off the main oil bearings instead of the main oil gallery it can cause oil starvation at low rpm when you would have the clutch pushed in. The 1993-94 DSM engines had the 7 bolt girdled block design but the early 6 bolt oil squirters design. Same with my 1992 Lancer GSR 7 bolt block.

Or a missing transmission to block bolt or dowel pin.

[@Jeffball610]

I think you covered just about everything. Good job. My favorite thing about the 4G63 is that it responds so well to modifications. Even essentially stock internal motors can make good power easily. My 4G63 RWD swapped Datsun 510 (#4G63510) made 285whp at 10psi on a GT3076 with everything else stock. Turning the boost up to 14psi it made 345whp. I built the head and was about to do cams before I saw the numbers and now I'm scared to make more power. A 2300lb car on 205 width tires is a handful :-)

[@nefariouscj9791]

fun video .... but if thats a billet crank so is my briggs & stratton and my 202 and and .... but if all pistons are at the top at any time your crank has brocken and or a couple of rods slow down ole chap... does a crank angle sensor not tell the hell tech where the pistons are and the cam sensor tell what the cam position is .........the m 12 bolts in the front timing sprocket might be m8 ole m8 and use an m12 socket to turn them .... just details ...not chem trails

Fuel economy was poor too. Then time came to change the timing belt. I found the camshaft was out by TWO TEETH! The belt was in OK condition, seemed tight enough, all the rollers were fine, I can only think the timing has been out by miles for the past 100,000 km! Needless to say, it's an entirely different beast now. Twice as fast on about half the fuel.

Awesome Video, I appreciates it, I have lot of headache too caused by so called balance shaft, mostly I works with Volkswagen-Audi and Mitsubishi engines I found about 75% failures /breakdown of upgraded engines comes from this things, mainly of balance shaft bearing "seizure" or lossed of belt / chain, my only recipe is to delete it and have the crankshaft, Piston and flywheel for old-fashioned way balance method at the machine shop, @ 4000rpm and higher "mild" vibrations still occur but still much safer than keeping balance shaft on the run, and affinally it is Up to the car owner some of Them just can't accept the ideas.
