Thread: S4 Cams Install Newbie

Maybe it was wet when that video was shot? Or he had poor tires? Both engines sound nice and strong if they are a cam'd DE. I dunno what you expected from a cam swap, maybe it was too much? I don't really see anything wrong with yours though. I like it.

Either way, wheel spin is technically losing power or becoming ineffective since the power is no longer being used in a more efficient way..........but I guess it is cool.

yea maybe you're right.

I guess turbo cars just ruined it for me. 400whp crx is no joke lol, I have yet to ride in a turboed sr20 but am sure it'll be faster

This s4 de is more than enough as a dd

knew you were a previous honda owner or honda fan just by your first post

Who says you dont need ecu? It makes big difference.



This is my setup back in a days... just JWT S4, HS 3" CAI and Calum ECU with base map. Stock header, cat, exhaust... and its EUDM 10:1 CR highport SR20DE.

Calum ecus still hard to find?

Yeah, its harder to find Calum ECU. This setup is from the days when Calum was active member.

You can buy Nismotronic, Nistune or others these days. Its works the same (or even better).

I wouldn't neccesarily want to spin the wheels in 1st gear. As someone else said, it's wasting energy and the more they're spinning, the less distance you're moving. Also, what wheels are you running? The light/smaller the wheels the better chance of spinning. If you are running big heavy 17" Konigs or something then I can see why.

I can't get the wheels to spin on my full bolt on DE either and I have 16" heavy-Konigs. The VE with 15" rota slip streams though, forget it. 1st gear is useless unless I'm careful

stock b14 wheels.

i just thought spinning 1st gear in a sweet spot in the powerband was going to be a symptom of the s4's.

storm, when will the power really come on after initial install? i'm only on 200mile mark of ecu relearning

Hmm stock b14 wheels. Are the tires really stick? Do you remember what brand they are? Just like all other things, you get what you pay for.

I've done about 6 cam installs in SR20 motors. This includes JWT S3's, JWT S4's (three times) '91 intake cam, JWT C2 cams, and Tomei Poncams.

If I remember correctly, it did take a good 150-200 miles of regular driving after the install for them to "kick in" - if that's the proper terminology.

I remember driving my very first '91 SE-R with the JWT S3 cams, and being sort of like "well, where's the power?" But they were brand new and I had to let them break in, I guess. I babied the car for about a week, then later that night I took off from a redlight and I could tell something was different, they kicked ass. The ECU def adjusted something. I still think the JWT S3/S4 cams are the best SR20 cams in the world.

Oh and don't forget JWT makes a specifically programmed ECU just for the SR20 with the S3/S4 cams. It tends to increase the ignition timing over certain areas of the powerband for an additional HP gain. If you don't have the JWT ECU you should look into it. Plus it gets rid of the lame lower rev limiter.
