DSM 4G63 vs. Evo 4G63
All motors can crank walk. I know of a bunch of them that " supposedly crankwalked had to do a lot with people were retards and don't do things right and the flywheel and clutch were not installed correctly causing the crank eat at the sides, along with the improper tq specs on the main caps. Majority of the "supposed" crank walks are problems with cluch not being installed correctly. Crankwalk was a product of the early 2g using a different 2 piece bearing and the motor not being properly oiled due to ****ty design.
About the time that Mitsubishi was ending production of the second generation DSM, Mitsubishi announced they had an engine available that had the crank walk problem addressed. I remember an owner purchasing and installing one of these engines but I never heard how it did.

I had 4 Eclipse 4g63 Gst & GSX. The last was built. I had around 12k in it. Yes its every bit as fast, but leaks and break downs were very common. I beat in my built Evo and don't think about it. The 90-94 motors were the best so if you were like me, and loved the 2g (95-99) you had a world of work a head of you. Cheaper to just get a Evo...lol.
I'm not sure what you mean by "supposed" crank walk. To me, crank walk is crank walk. I was active on the DSMtalk forum when all this was happening. Even owners with automatic transmissions were experiencing crank walk. When an owner experienced crank walk the only thing to do was junk the engine. This was because nobody knew how to fix a crank walked block. People tried but the result was that they crank walked again. Six bolt swaps were all the rage.

Depends, fast yes I agree, unreliable I don't agree with. The car was never ment to be what they are today. If you build one properly and take every measure to make sure they will last you a long time they are very reliable. What people do not do is get one replace everything that has importance and just beat the **** out of them and they break. Remember they are anywhere from 22 years to 14 years old. So people who buy them even 10 years ago still didn't replace things that should be replaced and they break.
interesting read,although there seems to be some misinformation regarding evo thrust washers...03-06 evo blocks use 2 180 degree thrust washers on opposite sides of the main that aren't integrated into the main bearings...

I had a 6 bolt swap GSX a few years back and I agree with you completely!
As I already wrote, DSMs were responsible for creating a generation of great mechanics. There was always something on the car that needed attention. And, the car appealed to young people, people who had tons of energy.
I remember a guy who was having trouble with his clutch. He pulled the transmission five times before he finally figured out that a piece of the clutch lining had come off and was wedged between the disc and pressure plate. But the best story is as follows:
There was a thread started on DSMtalk by a person who wanted to convert his normally aspirated car to a turbo. This was a common question and the normal advice given was to trade the car for a turbo. Doing a conversion just about required a donor car because everything was different and had to be swapped, starting with the engine.
With that advice given some fellow chimed in saying the job wasn't that difficult. He and his buddy, he wrote, owned several DSMs and they wanted to sell one. This was a normally aspirated car and they decided it would sell better if it was a turbo. So, they did the conversion.
Only one person responded to their ad., a father looking for a car for his daughter. The prospective buyer wasn't too hot on the idea of his daughter driving a turbocharged car so they swapped back to normally aspirated.

The thing is, any time a DSM breaks down, for any reason - somebody says "uh oh, CW." And there you go, the legend continues.
I drive my '98 GS-T more so then I do my Evo, and even though it now has a six bolt bottom, the car does well and holds up and doesn't have any issues. Other then the fact that it is not a 14 year old car and some things are wearing out - like I just did a rear wheel bearing last month. Other then that - no issues. I do think my Evo is put together better, but I don't blame that on Chyrsler or UAW autoworkers in Normal. It has a Japanese built engine and transmission and that's all that really matters IMO. Now that I don't race it or beat on it every time I get in it like I did years ago, the car has never even hiccuped.
