7 Bolt Motor, 6 Bolt Flywheel

[Beefyisme]

Ok here is my problem; I have a 1993 Eclipse GS, NON-TURBO,DOHC 2.0 4G63, automatic trans. I lost Overdrive in the auto trans, then decided to put the car in a ditch, so to fix all this I went out and bought a 1992 Chrysler Laser. The Laser has a 5 speed trans, NON-TURBO, DOHC 2.0 4G63.

Here was my plan; Take the motor from the 93 Eclipse and drop it in the 92 Laser... turns out the motor in the 93 Eclipse is a 7 Bolt and the motor in the 92 Laser is a 6 Bolt. The motor in the 92 Laser will not crank or I would be driving and not begging for help here.

The 6 Bolt Flywheel that is on the 5 speed trans (92 Laser) will not fit my 7 Bolt motor (93 Eclipse) and Mitsubishi wants around $500 for a 7 Bolt Flywheel. From everything I have read Flywheels from AWD & Turbo modles will not work with my FWD, NON-TURBO car. Is there anything.. ANYTHING I can do other than shell out $500 to Mitsubishi? I only paid $500 for the 93 Eclipse so I would almost rather slam my privates in a sliding glass door than pay what I did for the car for a Flywheel. Please oh please someone help this guy.

Is there a difference between 6 bolt turbo fwd and 6 bolt n/a flywheels? Id imagine that a fwd flywheel would be the same. I'd look on ebay though because the 7 bolt n/a lasted a little longer overseas.

Have you thought about buying a used flywheel? It would be inexpensive even including the cost of getting it resurfaced.

You can buy a used 7-bolt flywheel for much cheaper. Check the classifieds or DSM Graveyard - Your #1 Source for DSM Parts!

I know the clutches are different between the FWD turbo and non-turbo 4G63 models....not positive on the flywheel, but I'm sure it's different as well.

This flywheel says its compatible with both n/a and turbo.. Doesn't mean they are correct but it's something..

 

[crusada]

yea the 93 eclipse would be the first gen of the 7bolt check ebay the turbo flywheel should fit the non turbo for the exception of the 420A but if its a 4g63 non turbo 7 bolt you should beable to use a 93 turbo 7 bolt flywheel and it should work just as long as its the FWD turbo model youd need the 7 bolt flywheel 6 bolt clutch also the wiring and stuff is probably going to be different like when you would do a 7 bolt to 6 bolt swap in the turbo cars

Sorry about that. Bust like i said from what i saw the flywheels from the 7bolt 4g63 turbo or non turbo should match. For that fact to i didnt even know they made a non turbo 7 bolt. Thats just what i have found when i was looking online. Best of luck to you sir keep us updated on how it goes for you.

hopefully thats better

Wow, thank you everyone for all the help. I have found a few 7 Bolt Flywheels looking on ebay and the DSM Graveyard (thank you for the links) but I still do not know any of these will work since I'm non-turbo.

[This is a Used Flywheel from the 93-99 7 Bolt FWD DSMs. These are recommended to be resurfaced at your local shop before install. 11 inch - 7 Bolt.] <--- This is all the website tells me about this flywheel (DSM-Graveyard)

[1993 Mitsubishi Eclipse GS Hatchback 2-Door 2.0L 1997CC 122Cu. In. l4 GAS DOHC Naturally Aspirated] <---- This is what ebay tells me about the RFW0524 Resurfaced Flywheel The compatibility chart says it will fit: 1993 Mitsubishi Eclipse GS Hatchback 2-Door 2.0L 1997CC 122Cu. In. l4 GAS DOHC Naturally Aspirated. Seems correct but when you look at the notes on that year model it says: -->4 WHEEL/ALL WHEEL DRIVE-->106 TEETH - 7 BOLT CRANK

I may be dumb but Eclipse GS is FWD and not 4 wheel/all wheel drive.

 

[crusada]

Yes the GS is a FWD. I hope all goes well for you. Thoes flywheels should work i dont see why the flywheels would be different on them im pretty sure from the 6 bolt turbo to the 6 bolt non turbo the flywheels are the same they are setup the same in the car they use the same tranny if im correct as well.

The only difference in the 6 bolt turbo and non turbo motors is the oil squirter's in the block. So With that said i don't honestly see why the flywheels would be different.

I'd wager they simply don't know what they are talking about. Check ACT's site and you'll (I mean you in the general sense, not you particularly) see they don't even offer a replacement flywheel for non-turbo, 2.0L 1Gs. Why would that be if the flywheels were directly interchangeable?

yea the 93 eclipse would be the first gen of the 7bolt check ebay the turbo flywheel should fit the non turbo for the exception of the 420A but if its a 4g63 non turbo 7 bolt you should beable to use a 93 turbo 7 bolt flywheel and it should work just as long as its the FWD turbo model youd need the 7 bolt flywheel 6 bolt clutch also the wiring and stuff is probably going to be different like when you would do a 7 bolt to 6 bolt swap in the turbo cars

Turbo and non-turbo models use different clutches, pressure plates, starter plates, and have different transmission casings/bellhousings. That's a lot of variables to weed through and conclude that a non-turbo flywheel will work in place of a turbo flywheel. This is not to say you can't bolt up a non-turbo flywheel to a turbo engine, or vice versa, but rather to say you likely will be swapping more parts than just the flywheel.

Here's some food for thought. The N/T clutch disk is 215mm in diameter. The turbo clutch disk is 225mm in diameter. That means the turbo flywheel, at the very least, has an extra 5mm of friction surface all around. Take that a little further and the FWD turbo 7-bolt flywheel has 110 teeth on the ring gear, the non-turbo 7-bolt flywheel has 106 teeth. They use the same starter, meaning the diametral pitch of the ring gear must be the same on the two flywheels. Knowing that, you can conclude that the non-turbo flywheel is, overall, smaller in diameter than the turbo flywheel.

Yes the GS is a FWD. I hope all goes well for you. Thoes flywheels should work i dont see why the flywheels would be different on them im pretty sure from the 6 bolt turbo to the 6 bolt non turbo the flywheels are the same they are setup the same in the car they use the same tranny if im correct as well.

You are wrong on so many levels. Please don't give out misinformation.

 

[Beefyisme]

Well thats all I need to know.... anyone want to buy a couple of parts cars? I've always put Mitsubishi ahead of Honda and deffended DSM's over all other imports.. but I think its time for a Civic

 

[crusada]

i wasnt giving out any misinformation thats just what i looked at online and due to i didnt know all of this i stand corrected now. I was just trying to help and give him something to look for is all. As i stated to i didnt even know they offered a non turbo 7 bolt.

Define "misinformation".

So you now know, the flywheels are different, the transmissions are most definitely different, and there are a few more differences between turbo and non-turbo engines than just oil squirters depending on how (in)complete of an engine (bare block vs. throttle body to O2 housing long block) you are talking about. At least on a bare block you would be correct.

ya i just bought a 7 bolt fidanza flywheel off ebay and there are 10 left. not only that i only play 278 and it came a clutch plate and a pressure disc as part of a stage 2 clutch kit
