Manual swap question

[turge]

New Question:

The clutch on his eta is bad. Is there anyway that I can install a clutch and flywheel from an I car, or will that not work?

Also... one of my other friends has a 2 manual transmissions. the good transmission does not fit the driveshaft and but the bad one does. He mentioned swapping the output flanges. Is that possible? Seems pricy to me.

I'm contemplating my options since my motor blew and now is the perfect time to 5-speed swap.

Old / Answered Question:

I have a friend that is selling a 5 speed transmission off of an 1984 325e. I'd be going from an autotragic to a manual, so I understand I'd need the full set up, like the driveline, clutch, flywheel, etc...  Would the transmission from the 325e work with my 1988 325iC or are the gears different on the e - i models?

Thanks,

The gears in all Getrag 260's are the same. Using the transmission from an 84 325e will work, but you will have to use the sheet metal shifter and there will be the holes in the bell housing where the ETA timing sensors mounted.

What's the difference between the sensors or is it just the location of em?

The ETA cars have the timing and speed sensors for the DME located in the bell housing and the flywheel has timing slugs for those sensors. The M20B25 engine uses a front mounted crank position sensor and a cylinder ID sensor on the #6 plug wire timing and speed. Just two different ways of accomplishing the same thing.

You will want to use a flywheel meant for an M20B25. The ETA flywheel is much heavier.

Bump. I'm back to the manual swap.

The clutch on his eta is bad. Is there anyway that I can install a clutch and flywheel from an I car, or will that not work with an ETA?

Also... one of my other friends has a 2 manual transmissions. the good transmission does not fit the driveshaft and but the bad one does. He mentioned swapping the output flanges. Is that possible? Seems pricy to me.

Swapping the output flange is easy. kinda. you need a thin-walled 30mm Socket to get the nut that holds it on off. And you need to bend the tabs on the locking plate/washer under the nut so that they aren't locked against the flange. its kinda hard t explain.

Most 30mm sockets claim to be thin walled, but they don't fit. I bought 2 different ones before i figured this out. I just took an angle grinder and grinded away the metal on the outside of the socket until it fit.

I think the clutch is the same. If they are both single mass M20 Flywheels, then they should be the same.

[mkcman17]

Like he said, 30mm thin-walled socket and an impact gun. You can use single or dual mass flywheels, your starter will work on either.

Are you putting in an eta block/885 head? If so, good call sir.

[turge]

I already acquired a motor from a 325is so I will be using that. And hmm... it looks like I'll need a impact gun then if I go that route.

[mkcman17]

then why were you asking about an eta? that nut will be on there tight. instead of spending $$$ on a strong enough gun, why not take both trans by a shop and have them swap the flanges over? shouldn't be more than $20-30.

[turge]

gotcha. I called the shop I usually go to and they said they can do that for around that price.

[mkcman17]

boom, done. buy that clutch kit i posted.

[turge]

I don't have $200. The replacement engine took most of my money. :(

[mkcman17]

good, because it's only $115. don't be dumb.

[turge]

nvm... I was looking at the Exedy Clutch Kit. And I have to see how much I have after getting the other manual parts.

If you're using an i motor, go with an i flywheel, clutch and pressure plate. Done.

Alternatively you can use those 3 i parts on an e motor as well with no issues.

Make sure you replace your pilot and throwout bearings while you're in there and give your clutch slave cylinder a good inspection.
