I say the best mod is go to a big unused parking lot and have a go. Use the money for a set of new tyres waiting for you at home when your done.

 

Actually, I also prefer the dry cone type of filter to the oiled gauze type because it traps more particulates. The increased amount of dirt with the oil that passes through to the TB didn't make my map sensor fail, but it definitely built up more gunk than would normally be seen with the oem filter. I had to clean it off after a year of running with the K&N because the car would stall after startup of the warmed up engine. But yea, it is a myth that the oil type filter alone would cause the sensor to fail. I just didn't want to take chances with it in the longrun. I also rerouted the hose that runs from the valve cover and the pcv valve to a catchcan for the oil so none of it made its way into the intake stream. That was a bit of overkill but I won an HKS oil catchcan at SEMA so I thought what the heck, might as well make use of it.

Now on my ap2, everything is completely stock. I do miss the sound of the CAI at WOT however. But I am contemplating the FIPK, a Hondata gasket, and maybe the gears since the S2000 is just a local street and occasional track driver now.

 

I say sell the S2000 and buy a 350z

shouldn't cost that much

 

NOS !!!!

 

I used own a Boxster S that I raced SCCA and other formats with just for fun. The guy that built my engines for me said that I should only use a K&N filter. We would run week after week without doing much to the engine. We would alway check the filter after each race to make sure nothing big got into it. To make a long story short much of any kind of build up on the intake system.

I am a firm beliver in these filters. I think that most people that use them feel the same way. I also think that many people when cleaning their filters don't let them completely dry and then over spray them with too much oil. This is probably the biggest culprit of buildup in the TB and intake manifold. Just my opinions.

 

I've been running a K&N on my '01 S 2000 since a few weeks after I got it six years ago. Had to "recharge" it once. No problems. The reason I put the K&N on so quick after purchase (first minor mod) is that in my 48 years of messing around with cars, I've developed the ability to sort of "feel" things that aren't right. When I got my s2k, we were having hot days and cool nights. My car was really "bogging" in the day and running (by comparisson) like a bat out of hell in the evenings. During the day, I could feel it was being starved for air. Inststallation of the K&N was the first small step in solving this problem. My ultimate solution can be found in my link included in my post above.

 

It is nice to see someone close to my age that is on this site that make sence. My biggest problem is old habits die hard. As I said I am running a snorkle, the air box has been gutted and lined with 2 layers of insulating foil. I ran wothout the foil for about 6 months and than decided to line the box, which made a huge differance in performance. I also did a bypass on the throttle body coolant lines. There are some conflicting beliefs on this, all I can say is in the hot sunny south when it is in the 90s, it does make a differance.

For the time being and until I see for myself that the K&N filter is wrong for my car I am sticking with it.


marlonRocks; Sorry I stole your thread My Bad. If what you want is more torque, $500.00 will not buy you much, however if you are looking for a harder launch from a dead stop I would suggest gears. Good Luck

 

jimmyb and dolebludger are my heros

i would like to hear what you guys have to say about the other mods being discussed here, including the overall intake system and gears

 

Gears don't increase peak torque.

They do increase the "area-under-the-curve" and keep you at the higher-torque end of the rpm range for longer.

Less bog and waiting from slow speeds (low rpms).

But it does have the effect of losing 6th gear (effectively) for cruising.

 

JimmyB. and all:

After all the mods I've done to my intake, I guess I can't really say if the K&N filter element (taken by itself) is reallly helping me or not. All I know is that it is not hurting me (thus far). My so called "Dolebludger mod" to which a link is posted a couple of my posts above does include insulating the gutted stock air box, and insulating that part of the radiator top over which the air from my "air scoop" to the AUT passes. And I think that helps a bit.

Another thing about gears is they will decrease your highway gas mileage -- and may decrease your city mileage as well. I don't know how many of you care about this. If you don't , it is OK. But I do.

Given the very limited stock torque our engines have, and the very high state of tuning they are in stock form, there is actually very little we can do (short of FI) to dramatically increase it. Gears would be nice (for me) IF we had 7 or 8 speed trannsmissions. We don't.

But I do think the stock intake is a design defect, as it pulls air mainly from the engine bay, and right on top of the radiator where it is the hottest. I corrected that (see my post, which is two of my posts above). But still, I can't say that my s2k has gained a lot of torque -- just a little.

I must agree with some of the posters on this thread who have essentially said that if you want a lot of low end torque, you bought the wrong car. Because if we take into account the price of our cars (new or a good used one) PLUS the price of a good FI system, there are other and better choices for those wanting gobs of low end torque at the same or lower cost. Then you have to take into account that (to my observation) your resale value actually DECREASES on your s2k if you have done non-reversible mods to it. That is why all my mods (both performance and appearance) have been done with the idea in mind that I can reverse them on a Saturday afternoon, and take her to bone stock.

To buy one of these cars, you must really like the handling, steering. cornering, and performance post-VTEC. Because that is what they have to offer.
