When in 5th gear i get a whining sound. When im off the throttle its normal, but once i get on it again it will whine for a few seconds then go away. Dont know what it is.

Also I installed a ACT extreme clutch and p/plate. Its really hard and sometimes I have to double clutch to get the gears in, anyone experienced this before???

i currently have the heavy duty pressure plate with the 6 puck sprung copper ACT and i sometimes have to double clutch for the gears to go in smooth/good.

dunno if thats normal/good.

You guy must love your left feet...

I still maintain IMHO a street car for the most should use a street and strip setup unless you're making lots of power and/ or you use it mainly for racing...

Extreme stuff is going to ovbiously have more clamping force so essentially it may not "want" to let go easily... working the pedal a couple times will help. In AWD cars like the evo a clutch should be the "fuse in the line"... that should be the one to break rather than your drivetrain... and a heavy system like that will put more strain to it... as well as mounts etc.

Anyway back to topic, the whine could be from a high gear shaft bearing in your box... possibly it's time to pull it apart and check it over... or possibly (doubt) the gearbox fluid may be low...it seems that you're getting it whenever load is put on the main shaft as well so you could start your search from there.

It wouldn't hurt to check your TC as well just in case...

Pull donw box already, this is 'supposedly' a maintained box i got from a 'well reputed' mechanic.

I did some research today, i think my prob lies in my master/slave cylinder. The amount of pressure put out to move the piston on the slave cylinder is not enough to move the pressure plate back, also causing a small amount of fluid to move across the seals in the cylinder. I think the extreme was overkill.

Reason why i went with it was cause i burnt through a street and strip in less than a year, i thought i would have been better to go with something stronger, guess i was wrong...

Its not too much of a biatch to drive, i do Mayaro to Trinicity almost everyday so ive gotten used to it, but I spoke to someone and they said it wont be healthy for the stock thrust bearings. Think im gonna go with somthing from exedy or fidanza when funds presents itself, also will consider buying another box and flying in the parts to have it rebuilt stronger...

Wishfull thinking.

well so far, ive heard quite a number of reports of ACT setups going faster than b4. i think ACT either tried something new or they losing their quality? i dunno. my clutch setup went through about 3 weeks ago and i couldnt wait the time to fly in the one i really wanted so i just went with what was available at the time.

i think ill go street and strip when time/cash free up since my car is stock right now but i saw a nice HKS clutch setup and a OS Giken setup for our cars. hopeing to go that route when i start to mod, make some power.

I looking at the kits tunerimport bringing. Also, any of the 1g 2g setups from the eclipse will work for our application, so all the twin disc clutch kits will prolly be an option for me.
I think I will tear down my gearbox and have it rebuilt...

as mishi and other was saying tho, copper might be a bit too harsh for AWD, i can see this after having it in my car but will the twin disk setups also be too harsh?

or are they all cool once u know how to launch?

I drove a evo 5 that had the twin clutch setup, it launches well, grabs like a mofo, in regular driving when your picking up the groceries its not fierce at all and drives like a standard clutch. I

janfar,niceeee. i drove a r34 and a 300zx with twin disc setups, felt really nice. didnt know its similar feel to the evos also, according to what you described.

nice thread i agree with MISHI, i say its in ur gearbox or T-case...

janfar, how much TQ u making?

an extreme clutch like that does more bad than good IMO.

i had a similar prob i guess with a similar noise. when i now bougth the car, the gbox oil was almost none. so i drained, changed, flushed, changed again and it took the noise away.

have u ever had the noise b4? try a different gbox oil? im using the belray but im not sure if its tooo thick. what you guys use?

hmph · Posted: Sat Aug 08, 2009 7:23 pm Post subject:

Amsoil is what i use and great reviews from the states as well.

Redline is good to...

an extreme clutch can also cause crankwalk....

MISHI · Posted: Sat Aug 08, 2009 8:13 pm Post subject:

Just make sure that the oil you use is 75w-w85 or 75w-90 in GL4

and for the transfer case SAE 90 or 80W- 90 in GL5

For transfer and rear diff, it's good to replace the fluids every 6 months to a year especially is the car racks up many miles per day. Also good if you have small sweating or leaks along the seals.

well right now im running a 93T. CD5A model gsr. i currently run 20w50 amsoil in my engine. i think im gonna run amsoil all the way in truth yes. was also hearin that redline is best for our engines? or it makes no diff between amsoil and redline really, they both good?

also, i have a lil prob. when i drive my car slow, sometimes, not all the time, its kinda hard to go into 3rd. if i double clutch tho, it goes in ok. what can cause this? sometimes i might feel a type of grate. my shifter bushings are gone i think tho, the shifter has alot of play.

sorry for the thread hijack boy janfar but i think this can be a nice thread for people with our type cars to get some info.

Clutch was broken in according to ACT break in procedure over 500km. I will go look for the old clutch tomorrow and show you.

Nik, What in the joint you damaged, keep me updated.
