CRANKWALK

He's lucky it lasted even that long.7bolt dsm running 35+ psi on stock bottom end= pieces flying.

This had nothing to do with crankwalk but, had everything to do with over boosting. They have failed to make the proper modification to run such big turbo and, such high boost. Its not that the bottom end couldn't handle that much power. Its was simply because the bottom end couldn't handle that much boost. To safely run anything over 26psi on a stock 4g63 bottom end you must lower the compression ratio. Crankwalk does not come about from engine mods. Crankwalk occurs from high pressure clutchs and, inadequate rod bearing lubrication. Crankwalk is highly uncommon in 4g63 7bolt engine's its just that to many people are quick to blame crankwalk before properly determining the nature and cause of their true problem. :banghead:

Yeah, it was definately over boosting. I cringed as the boost gauge buried itself. I've run 19 lbs on stock internals for 10 years now with no problem. (DSM) But I would never go higher than that. It is fun to watch other people deystroy their own stuff though!

Are you joking? I have known 2 7bolt dsm's that have died from crankwalk in the last year just in my area.

It just comes about from the crank bearings being oil-starved because in the 7bolt, the crank is milled with a different surface than that of the 6bolt.

How many of them were modified and how many of them were FWD/AWD

NO kidding

[BoneMaro]

^hey you never know

both were fwd, one was modded. All im saying is, the 7bolt is a giant pile of ****....thats all.

I'm gunna have to go ahead and agree... for the most part. Some people will make the arguement of head combustion chamber design. But in terms of bottom end strength and port size, 6 bolt rocks!!!

^WERD

It cant be beat!

Well the subject of crankwalk may be some what of an opinion matter. I'm just simply stating facts from my experiences and observations. I've been dabbling in dsm's for over 8 years now. I owned 9 dsm's all together. All but one had a 420n/t engine and, the rest of them having 4g63t 7bolt engines. Starting from the early 93's all the way to the late 2nd gens. I have also worked at a mitsubishi dealership a few years ago as a parts salesman/mechanic for two years. In the two years of working there i have never encountered a single 4g63t dsm with crankwalk. Nor have i heard talk of such. I've only encountered crankwalk once on separate occasion where the vehicle had very high mileage along with many other major problems. I'm also basing my coments of crankwalk on the dsm community that i'm part of. It just doesn't happen anywhere near as often as some say it does. Anyway yes the 7bolt 4g63t engines are weaker than the 6 bolts but, not by much. The 6 bolt engine's has it's advantages such as stronger block, better flowing oil journals and, squirter, stronger rods, 1mm higher lift on the cam shafts, ect..... But it also has its disadvantages such as weaker pistons, velocity stacks aren't to great, the over sized head intake ports are to low and to big ect..... The problem is that alot of people fail to install proper supporting modifications when modifying their engines. Such as the guy in the video. Then they end up destroying their engine and blame every thing but, them selves.

The 4g63t engines are one of the strongest 4 cylinder engines out there. They have been in production for over 17 years now. Starting from their first use in gvr4 galants to dsm's to evo's. The 4g63t engine has been and still remains a serious contenders in the sport of Rallying. Thats why it still remains a 2.0L to comply with the regulations of Ralling. The 4g63t engine hasn't changed much from its old 6 bolt days. That it still uses the same engine code name 4g63t. The point is that 4g63t engine's didnt come thus far by being a pile of sh!t as mentioned. The 4g63t engine has proven it self by being a serious contender on the street as well as the track. By people such as John Shepherd, buschur racing and, many other dsm enthusiast such as my self. Anyway i'm not here to convince anyone of anything as everyone is entitled to his or her's opinion.
