I think they're secretly telling to put an LSx in

To an extent, but you can typically derive a 'round a bout' whp figure from weight and traps. Not exact, but if someone claims 400 whp in a s13, and traps 114...then you know it's only a 350ish car.

Yes. JWT S series cams are designed, cam dynoed, and designed specifically around the stock valvetrain. Their C series cams however are designed with more lift and ramp up, thus requiring the use of aftermarket springs.

I know of 5+ personal SR20 friends, with over 20,000 miles, all running S3 cams with JWT Ecus and the 7850 rev limit, all making above 330 whp, all of which get abused on HPDE days, that have had no issues.
In fact, i don't know anyone with JWT cams that have had valve spring issues, or even cam issues. I know of people snapping cams due to improper install/dissaembly, but nothign from operation.

I'll never disagree with safety issues, but in my personal experience, most OEM springs are better than some of the lesser priced aftermarket stuff. I like Supertech stuff, and JWT stuff as far as valvetrain is concerned. Some of the seat pressure stuff upon testing other companies (like BC) has totally pushed me away from them.
With that said, I would never EVER tell anyone with JWT S series cams to get springs, unless they are debating revving above the JWT imposed 7850 rev limit.
