I have been looking for tomei poncams but can?t seem to find any in stock anywhere. Is there any other options that work with the stock valve springs? Or does anyone have some for sale?

Jim Wolf S3 and S4 cams work perfectly on stock valvetrain. Also better than the Tomei sticks.

There is also the Brian crower cams with valve springs and retainers for around $630. But I don’t wanna buy anything cheaply made.

JWT cams are better than those in every aspect.

So JWT S3 camshafts with Stock valve springs and cam gears is a good way to go?

It is, they are designed to work with stock valvetrain, and don't need to be degree'd in with adjustable gears like BC.

Depending on what you want the S4 would be my choice though, barely less down low with better top end.

I’ll do some more research on the cams. If I don’t need cam gears that would be great.

dont use stock springs

match springs to the cam. The cam will recommend the spring. use the spring the cam recommends. Use a japanese name brand like hks greddy tomei JWT

That sounds good to me. Thank you guys. I think I’m settling for the s4’s. Checking out matching springs now. Thanks.

JWT Recommends stock springs on their S3 and S4 cams, that what they were designed for, and they work perfectly. I ran them in my first sr for 6 years and that thing hit limiter every time I drove it.
