Hello everyone,
I am going to replacing my clutch and flywheels, and planning to go FI at the end of year. Now, I just can't decide to go with ACT or JWT..the shop owner told me to go with ACT if I'm planning to go FI instead of JWT. Is it because JWT can't hold that much hp? (500+hp and tq)

Now I would go with below route:
1. JWT clutch and flywheel combo (don't know if it can hold up to 500+hp and tq, i know alot of ppl using it)

2. ACT heavy duty pressure plate 6 puck disc/streetlite flywheel (according to shop owner, hold up more than 500+hp and tq, but I tried my friend's car, its really heavy for DD, maybe need time to get use to it)

3. ACT heavy duty pressure plate street disc/streetlite flywheel (street disc hold up to 500+hp and tq and easier for DD?)

please give me some advise, I just don't want to listen to the shop owner because he got good deal on ACT..and my G35 is my daily drive also, acceptable chatting is OK, since I got exhaust/test pipe, Thanks!

 

anybody can help?

 

I say go ACT

JWT will not handle the power

Also look into Southbend clutches

 

Look into Exedy also. But if ACT and JWT are your only choices, definitely go ACT if you are gonna go FI.

 

Ok, Thanks guys! I will go for ACT, and is ACT street disc clutch hold up to 500+hp? or need to go for 6 puck disc?

 

well you can't just ask and not give a number your going for with your FI setup. There are other things you need to take into consideration too. It seems like your going for over 500whp and tq. Go ACT so you have piece of mind with your decision. Also when you replace your clutch and pressure plate i would suggest your flywheel to to lower your restriction you have going to your wheels. In other words getting a flywheel thats lighter will get you into the higher RPM faster due to less mass of the aftermarket flywheel. But what comes with that is some noise because the lighter flywheels don't have a dampener to dampen the vibrations caused by the transmission so you will hear some grinding sounds up to 2500 RPM.
Another thing, if your dropping your transmission already for your clutch/pressure plate/flywheel you should also get the following:
1) new flywheel bolts because the OEM star pattern bolts strip easily
2) nismo pilot bearing (or any new pilot bearing)
3) new throwout bearing
4) stronger (steel) pivotball (the OEM pivotball seems to snap easily under heavy load and hard driving conditions)
5) stainless steel clutch line so that you don't have a spongy pedal (prevents heat soak)

those are necessary but it's optional to get new clutch slave cylinder and clutch master cylinder for piece of mind.

also if your not going to be pushing over 500 tq to the wheels don't get a heavy duty clutch. you'll be sacrificing ride quality and you'll only get pissed off that you got more than you need for your setup. Even if you do go FI and you go over 400whp you will have to do bottom end work first so that you don't blow your rods out the side of your car....

 

Thanks man, I will take your advise when Im doing the job later on, and I will get those 1-5 items at the same time, also, I will rebuild my engine for sure, cuz I know it will blow my engine if I dont do that.

 

Does anyone know the Power Enterprise TT kit maximum rwhp and rwtq that we can push? with build engine.

 

Has anybody use ACT clutch with a Luk duel mass fly wheel ?
