clutch is kinda old, came with the motor, probably oem. Ive put about 8, 000 km on it, since i got motor.


well the end of last year right before I put the car away I noticed when I give her ... the engine revs up but no power to wheels...almost sounds like overboosting. but when im just cruising around granny shifting the car seems normal, as soon as I "give it", the engine revs up to about 4000rpm and then starts making that overboost noise and car does not go very fast at all.


im think its either
a) a boost leak(but the car doesnt stall????)
b) exhuast leak at manifold
c) clutch is done

any other suggestions of what it could be? bad grounds, ignition signal breaking up? timing?

I know its very hard to diagnoise a problem like this over the net, but its worth a shot, thanks in advance.

searched on youtube...heres what my car is doing:

does this necassarly mean the clutch is fried or could it be something else?

that vid is obviously a boost leak. but urs sounds like a worn clutch. unless it's making that noise

I kind of know what you are talking about.

My instincts tell me that if your clutch is slipping, you should see the revs going up faster than they normally would in a given gear, but your speed should go up slower than normal....

Try to pay attention to the tach and speedometer as you floor it to see if this is happening.

Also, if the clutch was slipping when you are flooring it like that, wouldn't you smell it ???

time to get an exedy stage 2 and fidanza.

ya my rpms are going up way faster and my speed is not doing fuck all. seems fine when im driving like a grandma..like 2k shifts. but asoon as a floor it the rpm shoots way up and my speed does fuck all. I think its the clutch cuz last summer a I remember smelling alot of clutch and I think today I was smelling it, but I just wasnt looking for it cuz I was out for only 15 mins(my license plates are expired, I was on my way to get a smog test). also this clutch is the one that came with my motor, im lucky it lasted this long. time to order a clutch I guess. yay for credit cards!

haha ya man im broke tho so i think i will just get flywheel resurfaced. mmm that bride feels like im driving a airplane or something. haha

I would say if your revs really are flying up but your speed isn't, then that's just gotta be the clutch right???

[S14DB]

yeah that clutch took a shit. I dunno why you would use the one in a clip. Been sitting for like 6 months at least.

[njd07]

owell, now what clutch does everyone reccomend for street duties, I have a all out track s13 which is almost done being built.

[Slow Poke]

What does it smell like? If you don't smell anything then it is probably NOT your clutch...

[96Turbo]

running 15 psi...i would probably find a stage 1 or 2 clutch to keep it streetable. The price on the OEM replacement Exedy's is great...but i'm not sure if it's got the grip that you need

[csflame4322]

for a new clutch look at an ACT heavy duty street strip kit. its a full faced organic sprung disc and the pressure plate has a near stock pedal feel. just put one in my buddies s14 with a mod list nearly identical to yours (technosquare tune) and it hooks up great!

I just ordered my Stage 2. I was having the exact same problem. Initially I thought it was a boost leak. Took apart everything, and Its the clutch..

ya and ussaully when i have a boost leak the car stalls. the engine seems to be boosting up great ...just no power to the wheels. did you get the exedy stage 2? how much was it?

[Jung918]

press the gas and brake at the same time. if it shoots up, it is the clutch. cant go wrong with exedy
