Thread: JWT S4HL Cams

Has anyone mounted these cams yet? If so what kind of improvement did you see and what cams did you have on before?, because i bought the JWT S4HL already and just want to see what kind of improvement to expect compared to the JWT S3 i currently have one

I don't have experience with s4hl's but I can tell you it moves the powerband in the upper rpms.

should be nice paired w/ boost, esp smaller turbos.

i hope to have better top end & better pull compared to the S3, and i also hope to see atleast some HP increase

I ran these with my t25. They are excellent above 5500rpm and doing pulls on the interstate is so much fun. Power goes all the way to 7500 and the car loved it. If you have a small frame turbo I think you will love these cams.

Hey, if you're looking to sell those S3 cams I know who will by them.

^^ LOL! I have been pming Black back and forth as I found a set on G20.net he may be interested in

You guys are awesome lol!

Good looking out!

But yea, if you are interested in selling the s3s I'd be interested.

I have a pair of s3's that I'm selling. lmk

So the s4hl cams are the safe alternative to s5 cams? I read bad reviews about s5s

I'd like to know as well. Even Greg warns about the S5 cams on G-Spec.com:

S5 Cams, 2.0, S5 CAM SET SR20 BILLET . **These cams can cause coil-bind in the stock springs. It is recommended that the optional springs are used.

Greg is a very honest guy so I'd take it as warning.
