Performance Increase

Aug 15th, 2002, 08:05 AM

Are there performance chips for the Spec V. How else can I increase performance?
Thanx
Don't K&N air filters let in a lot of debris?

Answer:
K&N filters stop more garbage then most filters, but not as much as the cardboard filter your stock car has. The small amout of very small particles it alows past is not enough to do damage to your motor. Most people can atest to having had no issues. I have 100,000 miles on my integra most of that with a K&N filter of one kind or another (box,short ram, cold air). I know many peole who have had them since day one of their cars existance and have 100,000+ miles with no problems. My Dad's Maxima had one from 5,000 thru the 50,000 it had on it when he sold it. Anyway you get the point.

Chips... that is a little more harry, we all want one, we know there are prototypes, but nobody is selling chips yet. YET but we all know there coming soon, the demand is there, and there needed for high end tuning of or motors.

Other choices... there is a HotShot Header for our car thay dynos at +12hp. There is a stromung exhaust that is a good gain with the header and CAI (cold air intake). Other than that we are so restricted by the ECU that the next best things are removals... IE: grounding of the knock sensor, or balance shaft removal.

Hope this helps

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

whats the gain of the grounded knock sensor? what do you do?

stillen told me yesterday that they were working on a chip too, imagine no 6100 rpm fuel cut off!!

cortrim1 · Aug 23rd, 2002, 06:15 AM

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 heard the jwt is developing, new valves and springs to go with a new chip

Your car will rev faster.

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.

cortrim,

Hook me up....what exactly are the balance shafts and how do you remove them? Do you have a link where it says that removal won't do any damage?

stealthb14 · Aug 27th, 2002, 07:26 PM

We actually have a thread on the Balance Shaft Removal. Torry (ezcheeze15), removed them from his Spec V. You can read about it here: http://www.nissanforums.com/showthre...s=&threadid=48

I found it using the search feature
