Thread: Rods and cams

Okay, first of all, it's parallel. Secondly, the term parallel is used to signify that both cams are of the same duration, lift, etc; not a cam manufacturer. Just like a parallelogram. In other words, a cam set that isn't parallel, would have one cam, at say 264 degrees, and the other at 272 degrees. This obviously isn't a parallel cam configuration, as they are not the same cam profile. (This was also stated above).

In essence, you're wanting to compare JWT S4's, to BC Stage 2's, not "parallels." (no such manufacturer.)

You don't really need to compare just JWT, to BC, though. There is no comparison between S4's and BC STG 2's, as MANY have stated in the past. If you're to compare the STG 2's with ANY product from JWT, it'd be more like C1's or C2's. (Likely closer to C1's.)

Don't forget to look into HKS cams, Tomei cams, etc. S4's are just highly recommended, as many use them on stock springs and retainers, and they make TONS of power. Even more power than BC STG 2's. (This should be an obvious giveaway, though, with regards to cam design.)

thanks you said it a little better than what i said

THANKYOU!!! for clearing that up, first time parallel was mentioned, i thought it was a company, second time it was explained i assumed it was duration272/272 or 264/264 (both cams having same) then third time it was mentioned, it went back to getting the impression that it was a company again, got it now, jwt s4's is what i'll go with because i can keep the stock retainers and springs, crower recommends not using stock retainers and springs

Exactly. BC doesn't recommend stock springs and retainers, due to the agressive lobe profile. You could install the S2's without springs and retainers, as some do, but I wouldn't want to take your motor past 7K on a regular basis, due to increased risks of valve float.

I myself, have gone with the BC STG 2 cams, with springs and retainers. Together, everything cost me roughly $400, which isn't bad, in comparison to S4's. I did this with the thought process, though, that I would eventually go with a larger cam profile, which would lead me to needing springs and retainers, anyhow. So, rather than spending $500 some-odd dollars on cams alone, I spent it on cams, springs, and retainers. Now, when I decide to go with a larger cam design, I'm not spending it on springs and retainers again.

i agree but really the camshafts depends on the goal you are looking to make....if you arent looking for a ton of power you can get away with camashfts that dont need springs and retainers.

Agreed. I personally believe that the S4's are a great choice, as they make really good power N/A, and gobs of power in forced induction applications. All while not needing springs and retainers. I just chose to go a different route

ok understood, did u manage to get those cams/retainers/spring new or used for $400? i was looking online today, bc cams were like $330 and $360 alone on two sites

I bought the STG 2 cams for $220, new in box, and the Springs and Retainers for $210, new in box.

I got them from SR20TurboFreak, on sr20forum.com. I don't think he's really active, anymore, though.

You could check with SBC (Slow Boy Racing). I believe their costs are roughly the same as what I paid for mine.

what duration are those stage 2?

IIRC, the STG2's are 264's; 12.05mm lift.
