Question jwt S3 cams

I really want to make my car go faster and ive raced alot of people in my P11 and i just seem to be either next to them or one car behind. Just how reliable and much of a HP increase should i expect from these cams. Also are they trust worthy.

What year is your P11? You may not be able to use the S3 cams. The roller rocker engines came out in 2000 I believe. You'll have to wait for JWT's cams for that. If you have a 99, you can use them.

You should make around 15-16 hp with the S3 cams.

I have a 2000 with the roller rockers but i can get cams direct from JWT through this guy in miami that does nissans. Alot of people recommended him to me and most of them has SE-Rs and havent lost a race yet. If anybody has heard of him he goes by the name of Andre and can also get anything from HS direct. I went to his house for the first time and by just looking under the hood he told me i had limited slip and rollerrockers and bunch of other good things. Then he called JWT and he was telling them if they had anything out for the 2000 model and they said that they were trying some new cams on there test models and i can have a set by two weeks, I spoke with about four months ago though but i didnt have the money back then. Just wanted you guys to know.

The S3's gain a good amount of top end lose a little low end and have a mild idle lope.

The S4's provide more top end power but have a lumpier idle and lose more in the bottom end.

So trag, you're gonna have the test cams, but JWT doesnt have them ready for the public yet? Just wondering cuz i have a 2001 and want to get a set of cams. By the way if you get them keep us posted.

Like George said in another post the JWT s3 cams will be realice in about 4-6 moths for the roller rocker motor.

Yep, I know of Andreas Miko. Quite the tuner. I've chatted with him before.

But, number one, the S3 cams are not for the roller rocker engine. Second, I talked with Mike Kojima and Rob Cadle, who are heavily involved with JWT's cam developement and the new roller cams are very promising. But, they want to do some more testing. This was a month or so ago. I kind of doubt they are available yet, but they are getting close.

i thought even the jap made 99 P11 ones are rolloer rockers too?
is there anyway that i could find out if my engine has roller rocker cams or solid rocker cams?

well if my engine uses solid rocker i am gonna order the s3 or the c2 cams when i have the money then

how much do they go for anyway?

It's pretty easy and you can tell just by poping your hood. The roller rocker engines have a deeper channel where the spark plugs are. This is a normal solid rocker arm engine.

...and this is a roller rocker engine. Notice how much deeper the spark plug wires appear to be?
