i got both clutch (ACT) and light flywheelfrom Stillen (14lbs)

 

maybe Tony can give you a better answer, but it gets hot overhere and when i had stage 3 , i never experienced a problem. i drive my car everyday and push it almost everyday. but again jere we use 98 octane which can help.
now i have stage 4 and i also drive my car as before, the car seems even smoother than before. The addition of new fuel pump and lbigger injector (more fuel) makes it very safe. As far as feel is concerned , it feels smoother now and nicer to drive

 

KJR Pulley? is that the same as the UR pulley? and if not, what is the difference? Stillen tells me to use the OEM Pulley...... so why would the KJR be better then the OEM?
thanks for the info with the Clutch and flywheel DrG.... but can you just run with flywheel alone without the clutch upgrade? if so would it be a disadvantage?

 

Awesome... I will be looking into stage 4 as soon as I get my body work done and some sways.

 

hey man no problem... the KJR and UR are two different brands or manufacturers of crank pulley. they both make lighter crank pulleys. i believe Stillen carries the UR (unorthodox racing) pulley. a lighter pulley will make the crank shaft rotate quicker when accelerating , the car will respond faster and will accelerate quicker as if it is a lighter car.
As far as the clutch/flywheel is concerned, you can get the flywheel alone no need to change the clutch. However, changing the flywheel will require taking the transmission and clutch out which is a 4-6 hours job by a trained mechanic!, so if your clutch is old i recommend to change both together. If your clutch is new, wait until it gets a bit worn out so it is worth it to take the transmission down and to change the clutch with the flywheel ( you will avoid doing this job twice once for flywheel and then again for clutch) anyways it is your choice and how anxious you are to get the flywheel. This is what i have done , i waited until my clutch is worn out (not completely though it had 25K on it) . Now you can always keep your stock clutch , it works fine it is a good clutch, however logically it will not last as long as it should because of increased power. in my case i felt that it is getting worn out after the SC modification. the clutch felt soft ready to slip. Clutch life depends on your driving, some people never change clutches. but if you want a crisp response , and a clutch that will last longer and can handle more power it is better to change it. i got the ACT clutch from Stillen , it is very good and the pedal feels almost like stock a tiny bit harder. The flywheel will make the car accelerate much faster, it is a great mod . comparing it with the pulley: with the crank pulley you are lightening the rotational mass by 5 -6 lbs on a small diameter, with the flywheel you are reducing the rotational mass of the stock flywheel by almost 14 lbs on a large diameter, large diameter means more inertia means better results.

 

We carry both the UR and the KJR.
However, if you run a SC, go with the KJR, as it's stock sized, just lighter weight. A UR pulley won't work well with a SC due to the complications in belt sizing etc...

 

How well will the Stage 4 work with the 5AT?

 

It works great. 13.0 @ 105.7 , 5AT on street tires. First gear is wicked. 2nd is more wicked than first. When i put my 1/8 times into the 0 to 60mile formula it read 4.1 seconds. Only did this once at I- 41 speedway. It was witnessed by the G 35 guys who ran there that day. The track had awsume traction for coming off the line. Had to launch at 750 rpm or it just spins the tires. Had the stock fuel pump and it ran out of fuel preasure at 5900 rpm. Just got my pro torque converter from Nick at performance motor sports today. With the weld 15x8 rims at ET slicks it should go 12.5. this summer. The ported blower should make 342 rwhp and with it we are hoping to go 12.25 to 12.30. How much power does your 5 AT make?

thanks a mil dr g...... i appreciate the answer....

 

Colin,

Thought you were going the TT route...Guess not huh? Let me know when you do your install. I would like to check it out! See ya around.

Nilo

 

I wish you very best with your company and I really wanna see it grows and flourishes within the G/Z community and expands its way towards the whole Nissian community !!

May I wish you the very best

My motor is stock (for now) except for a Stillen cai, so basically stock numbers.

 

I still am at some point, but who can say no to more power for $800 besides, the whole kit has to come off so that I can fix this ....



BTW, Stillen have been fantastic about helping me with this problem, thanks Sam

I'm running the Stillen Stage 4 sc also. The shop that did the install for me says that adding a KJR crank pulley will cause a drop in boost? Any idea if this is this true (if so, i don't understand why)?

 

what are we looking at? pls to expain.

 

This is the idler pulley shaft (with pulley still attached) that has snapped and fallen down into the space behind the timing covers ... luckily I wasn't on it at the time or the carnage could have been major, talk about spinning top of death ....

You should have seen my face when I opened the hood and found the S/C belt just sitting on top of the blower ...

Wow! Scary! Did you have the warranty?

 

As I mentioned before, Stillen are taking care of me and nothing else was broken so I was extremely lucky

 

Right I got that they were taking care of you, but I was wondering if its because you bought the warranty or if they are taking care of you without it.
