thats whats put me off, oh yea and the $500+ asking price!
The s3r's are a different variant than the conventional cams. You can run stock timing or up to 19 degrees with them on the stock ECU n/a. If you hear valve float, back off timing.
I've had a wierd experience with them, when I installed them I didn't feel much of a difference at first because they are moderate, But after driving with them for a while it feels a little better. I just think the 98 ecu is touchy touchy for some reason. If you get s3r's go in with low expectations; they are not s4's.
If you get them reset your ECU for a day or so, and don't be afraid to Drive Hard after your break them in. There is NO difference down low with these cams... the difference is between 4.5ish and Redline. Unfortunately, if your rev limit is held at 6.5k or so you can't take full advantage of the cam. My rev limit is 7.1k and the **** climbs so fast after 5k is hilarious; i still sometimes hit the limiter.
I can tell you after having these in for roughly 8 months or so that the car DEFINITELY is faster on the highway. It climbs to 100 very fast.... 3rd and 4th gear feel a lot better.
I honestly think if you got a lightweight flywheel with these cams, an intake, full 2.25 or 2.5, high flow cat, and a header, and some thermoblock spacers... you will have yourself a really fun daily driver. Since I've sold my b13, I've been enjoying my b14 a lot more and the car is just a blast to drive.
I just bought a fidanza flywheel (the last mod), and I'm pretty excited about what the car will feel like after it. I'm actually scared, because it was breaking 2nd at high rpm when it was a little moist yesterday just holding gas down (no clutch) and that's with the stock 22lb flywheel.
