Yea, I've heard that for years re: my 98 Sentra SR20. I'm not trying to jump on anyone, or sound negative. JWT has been very very good to us.

Pretty good Aftermarket support, not even been out a whole year.
there is already a prototype for the spec v. why else would jwt have cams and valve spring comming out for the spec v. btw the prototype cams are in a pro rally car right now:D

chip

I have heard rumors of a chip as well, but nissan cars traditionaly have needed a piggy back board for the ecu. Also raising the rev limiter would not help unless you get better valve springs and remove the balanced shafts. The balanced shafts will lock up at 7000rpm(engine speed) causing the motor to lock up. :(

I know this has probably already been answered, but whut does taking out the balancing shafts do. IE, whut are the advantages, and disadvantages?

Sorry for a probable repost.
removing the balanced shafts will free up 8hp, and according to the experts will have no ill effects on your motor. So think of it as free hp trapped in your motor.:cool:

I have not heard anything about them locking up at 7K now what i'm curious about is just what is the reason for them.. is is to cancel low end vibration? do they stablize the lower end?
nissan put it there for a reason and dammit i wanna know :D .
and i read Torry's post about it, and im wondering if the removal is reversable. since you have to (quick way) cut the chain that drives it.
I know that some other cars used something similar like the ghost of a car the mitsubishi starion (friend of mine has one)

so if anyone knows and can tell me what this thingy is really for. I would greatly appreciate it.

i want to remove it but im a little hesitant.

the balance shafts are there to soak up the vibration cause by the rods moving up and down. They are in the car because this motor is large(displacment)for a four cyclinder, and was designed for the altima not the spec v so they are there more for comfort. Yes you can cut the timing chain but you might experience a oil pressure loss due to the fact the b/s are still being fed oil. Also the b/s assembly weighs 40lbs so removing it will save some weight. Btw the info I got on the b/s from a person who has already blown up the qr25de and had one lock up due to the b/s.;)
