Question about DSM engine

[honda1982]

I just recently brough a 95 Talon AWD w/ no motor. I just wonder if a 91 Eclipse AWD motor fit in it? A friend of mine say it can't be done because of the motor mount. If not than I have to buy a 2nd gen DSM motor. What's the prices on those 2nd gen AWD motor? Can a Talon AWD TSI w/stock turbo and some mods(boost controller, SAFC,etc..) make a high 13 sec 1/4 mile pass?

in 93, they switched to a 7 bolt motor which is more prone to crankwalk once you start modding.

90-92 had 6 bolt motors.

Putting a 6 bolt motor is definatly possible, I have numberous friends with 6 bolt (first generation motors) in their 2g's.. As far as the motor mount, you might have to use some other parts, but no aftermarket parts.

Yes a 13 sec pass is possible with those mods and a few more. As long as the motor and turbo are healthy.

Crankwalk can become even more of an issue with a heavy clutch but it does seem to be more prone to the 7 bolt that came in the 2nd gens vs the 1st gen 7 bolt. My '93 had an ACT 2600 (ok,a few of them) for almost 75,000 miles and the crank was fine but CW can just show up and if a 6 bolt is available then jump on it.

Plus the 6 bolts are stronger than the 7 bolts.

In '93 Mitsu did go with alot of internal upgrades over the early 6 bolts including less rotational mass due to lighter parts and any 1st gen engine should be good and even the 7 bolt late '92-'94 engines rarely CWed.

[Skaterkid]

The crank walk is due to the oil squirter change from drawing oil from the main galley to using the main bearing oil supply. The squirters get stuck open at idle, and the thrust bearing is robbed of oil.

[V8SpankR]

And for some reason it became very prone in the '95+ models.

Really?

I have 2 modded 95s. One has been beat on for 40k miles (dyno'd 350 awhp), the other has over 120k (daily driver).

Both STOCK BLOCKS!

Don't spread mis-information.

Oh, and the "crankwalk theory" was started on the Talon Digest back in 1995 as a way to keep people from buying more DSMs. :p

hope this helps

Still a percentage of 4g63s did walk and according to the survey on dsmtalk a while back and 9 out of 10 that did walk were 2nd gen motors. How is this misinformation? I even know three people personally that their 2nd gens walked and two of them were stock.

[Skaterkid]

It's not misinformation. The 2nd gen's have smaller journal area, a better head, better lubrication, and a stronger crank. They still are strong, but not as strong as the earlier engines. Plus, crankwalk is a real issue. Get those squirters stuck open at idle and kiss your thrust bearing goodbye.

[hoffman]

Check that survey that Mitsu compilied again. It wasn't '95s with the highest number. The '95 motor and '99 have the lowest numbers (probably because '99s don't have high milage when that survey was conducted).

I also know people that have "walked" 2g motors, and it's mainly the '97. Which is exactly what came out of that survey and what is considered general knowledge in the DSM community.

Misinformation may have been the wrong word, but not about the '95s. That also can be true about 6bolts being bulletproof too. They "walk" just the same.

The "Digest" bit was just sarcasim.

[V8SpankR]

Well,CW is still much more common in the 2nd G vs the 1st G period but any 4g63 can walk and that's the misconception of the 6 bolt motors. So,I wonder why it was more common in just a couple of years of those motors;is it just a conincidence?

The early six-bolt is a superior engine, stronger crank and stronger rods. A few vendors won't even build a seven bolt engine.

'97 was a very bad year for crankwalking 4G63's. Six bolts can walk, but they are the exception and usually have a million miles on them or have been rebuilt improperly.

My DSM is a daily driven 6-bolt that has had an ACT 2600 in it for over 4 years now without issue.

honda1982, tell your friend to be quiet and put a properly built six-bolt in that 2G using the right parts.

[V8SpankR]

I was fortunate with my 7 bolt since mine was modded for over 2/3rds of it's miles when i had it and it's still going strong on it's 4th 2600 and still pulls low 13s down in NM.
