Thanks!!! Looks like I'm going with the S series, But in the meantime I'll throw these '91 Primera ones in there hopefully I don't need the ECU yet. Your opinion?

JWT S4's. Or S3's if you want a little more low end.

The 91 cam is ok, but you'd be alot happier with the S series.

Yeah... stick with the S3/S4 cams... best for whatever you may be getting them for.

Will the S3 cams need new springs and retainers? Or will the stock springs and retainers be fine? Just wondering for future reference. TIA

Yeah, I'll go with the a S series cam. But I do have a '91 Primera cam laying around in the garage. Would I see some type of gain if I install this cam with the stock ecu or should I not even bother and sell it?

the JWT S-series cams do not require to upgrade the valve springs and retainers luckily:D But if you plan on moving up to the more aggressive C-series cams then you will have to pay Mr. Wolf 600 for those springs and retainers. As for the primera intake cam, yes it is worth it..one of the best bang for your buck upgrades to any 94-up SR20's...hope this helps

i have have the 91 cams. my car is still slow as shit
