1.6 to 1.8 clutch and flywheel upgrade
 

:idea:Got the car all apart in the garage and have decided to do the 1.8 clutch in my 1.6 car. Got an OEM Mazda pp and disc, having a problem finding a 1.8 flywheel around here. Seen a bunch on Ebay. I'm thinking of the F1 lightweight flywheel at around 11lbs. Anyone ahve any stories on these, are they any good, does the flywheel really matter that much! Or should I play it safe and order a FM light flywheel. Up on stand at a standstill. Thanks for the input.

Ive read and heard lots of good news about the F1 flywheels. Stay away from the aluminum ones unless you really need to be that light. It's not worth the risk of over heat if ya don't need to. A lighter flywheel means better throttle response less rotating mass and the "feeling" of a bit more power. I just ordered mine a few days ago and can't wait to get it in. Its advised to have the clutch "kit" spin balance as a whole. Most of the balance sheets I've seen are very good out of the box however. Usually within .5g which is within the tolerance range.

Don't forget to do the rear main, trans input, pump, tail shaft seals and cps O-ring while your in there.

I have the F1 cromoly one. Zero issues, except the 8 mm threads for the bolts that hold the clutch cover to the flywheel are of a different thread, so I had to buy a bunch of those from a local hardware store. I had the balance checked and it was spot on.

thanks for the input, F1 it is. Be back after it gets here and in.

Did you have any problems with installation? My mechanic called me saying the slave cylinder is not pushing the rod far enough to move the clutch. Any ideas?

FWIW. Strongly suggest adjusting clutch pedal first.

Personally, I'd not be putting cheapo, known-questionable goods (F1) in a spot that's hard to get to.

F1 clutches are notorious for this issue. this is what happens when you spend $50 on a clutch.

read the details, not an Fm clutch, exedy clutch with and fm flywheel, their flywheels have had great success.

Just bleed the slave 50 times more than you think is necessary, and then adjust the clutch pedal.

I put a F1 flywheel with the FM clutch on my 92. There were no problems putting it on except when the slave cylinder practicly exploded due to the extra force required to disengage / engage the clutch. I just picked up a replacement at auto zone for $15 and all is well. I didn't even have to adjust the pedal from stock.

Sorry. No Cunts Allowed.

Guess I saw that one coming. Newbs gotta wait till Scotty has his coffee.

Oh I had my coffee...he would have known if he read the details.

:brain:

Well fuck me. I didn't even catch that anyone mentioned an exedy clutch until just now. Working 12 hour night shifts messes with my train of thought.

it wasn't you. swartzzk bumped a two year old thread referencing an issue with F1 clutches.

LOLZ, I didn't see that until now! Damn it. :facepalm:

Those F1 units are tempting, has anyone lapped or raced with one?
For the price I'd be puckered up expecting it to scatter.

Clutches don't disengage, flywheels aren't fully machined. You get what you pay for.

And with the amount of work that it takes to swap out a clutch, spend the money on a good one the first time. 949 Racing, ACT, FM are the only clutch brands that I can recommend.

Something is bugging me here,.... why is a 1.6 to 1.8 clutch an "upgrade" ?

More mass = more gooder ?!?
