Best Manual Tranny

[robertisaar]

essentially: it's about twice as thick(and therefore heavy) as a regular flywheel, absorbs a LOT of vibrations that would otherwise travel into the transaxle, possibly causing damage.

Is it possible to make a dual-mass flywheel light weight?

[robertisaar]

all 60V6 flywheels will interchange. you could use a Fidanza aluminum one if you really wanted to.

but there has been some contraversy about wether you should use a different flywheel. some claim it increases the torque capacity, makes it last longer, etc due to it helping to cancel the bad harmonics that would otherwise travel unchecked through the drivetrain.

i honestly believe that group. there are also benefits to a heavier flywheel, but most of them aren't benefits for a balls-to-the-wall car.

I want a tranny that is durable but not too heavy.

weight is usually a sign of durability.

the 282 is fairly light, less than 100 lbs dry, IIRC.

the 284 is ~150, i think.

the F40 is listed at 124, but i'm not sure if that is filled or dry...

the 282 with a '88 beretta jackshaft and housing is about 60 lbs dry.

282's have been proven to take 400-500 HP/TQ all day. They do not like to shift above 6500 RPM or so. Upgraded synchros should fix that. If you get one it's also a good idea to have a trans shop go through it to make sure the diff bearings are shimmed right. higher mileage 282's tend to have a problem with the diff twisting and breaking the trans case.

mine has 142K on it, other than a recent 2nd gear synchro issue it's holding up to 320 HP/300 TQ, launching hard on slicks. I did weld the diff which is helping keep it alive. Original GM axles too..

About how much power can the 284 handle?

Over 9000.

My 284 in my heavy pig of a car (read loaded down with dynamat from the previous owner, so it weighs more than a normal W) still shifts just fine at 7,100 rpms- and it's an original tranny (141k) that has never been opened or rebuilt Some (like mine) tend to be cranky while cold though and you will have to shift slow until it warms up which is fine with me, you shouldn't be beating the tar out of a cold car in the first place. If you do, you need your head examined.

It's too bad i'm not keeping my cavalier or i'd have to try out a 284 in it.. my engine would love to be able to shift that high.

I didn't know you welded your diff. How does it feel since then compared to previous?

Do you think a 284 would bolt up to a '95 lq1 engine?

if it doesn't, you're doing something horribly wrong.

what about thje tranny on the quad 4? it was a 282 but the limiter on those car was setted for 6800? didnt seem like a problem when myne shifted at 7400.

quad4 had a different bellhousing pattern IIRC...
