OKay, trannys in. still grinds every once in awhile. Fuck... The piston on the slave cyl. falls out. that the issue? i dont understand.. it only does it sometimes and never seems to do it(or atleast i dont catch it) when upshifting

bent the linkage about 4 degrees. problem solved. yep...


Can anyone tell me how much power stock cams are good for? ive heard 300 but that doesnt quite make sense to me.

oh, and 2.93 lsd and revshift guibo are on the way. finally finishing my exhaust as well

i believe im still having issues. probably swapping back to g240 because im moving to ca on saturday and dont have the time nor the resources to figure it out.. fuck. have some gnar clutch chatter too so its hard for me to distinguish what the noises are from. finished my exhaust too. its ugly. and my fender touched my wheel and took the paint off. love/hate my car.

I dont think the factory cams are a handicap. There is more of a rpm limit with the cams than a power limit.

If you need more power...more boost

thanks for the replies, wazzu!

So ive been thinking more about my trans dilemma. could it be that im using an m42 flywheel with an m20 clutch? why is it eating trannys?!

The clutch and pressure plate are M20 units? How did you do that? I tried this route with no luck!

i could only use the M20 stuff with M20 flywheel.

What is failing on the transmission?

When you put in a new trans, remember to replace the clutch fork pivot pin. If its ground down from wear, the clutch wont disengage

I told vac i wanted a clutch kit with an m42 flywheel and an m20 clutch. Does the factory m20 clutch not bolt to a factory m42 flywheel?

Would the pivot pin really have that kind of effect?

You can not install m20 clutch on m42 flywheel. Slave cylinder for E36 gearbox is different, but you can make just the rod longer to prevent it falling out. In case rod is too short free travel of the clutch pedal would be very big and could be you would not be able to disengage clutch at all. Sounds from the gearbox could be because there is no oil, oil level is too low or not correct oil was used. Could you please explain what exactly happened to your gearbox? Have you checked pilot bearing? Is it correct diameter?

Im using a getrag 260. The slave cyl. on the g240 and g260 is the same. Theres oil in the trans. I filled it to the proper level before installing and teh seals are new so theres no leaks. I checked the pilot bearing before installing it. They sent me the wrong one with the kit but i got the correct one installed. I am unsure about the TOB. it fits, but could it be too long/short? and since its an m42 dual mass fw could that be it?

If the TOB is too short you will not be able to disengage the clutch properly. If its too long, your clutch may never fully clamp down.

Sounds like your issue may be too short of a TOB from the grinding.

In this case it is possible to make slave cylinder rod longer or adjustable.

Hmm... Do you think that because the flywheel is much thicker than the original flywheel that the clutch may be over engaging? Maybe a simple clutch stop would fix this? Ive toyed with the idea before and it does seem to shift well when i press the clutch about 1/2 to 3/4 of the way down.
