Brian Crower webSite does not have these cams listed so you have to call and order.

i was gonna post that up but i didnt think anyone from this site is intrested in cams. I called BC cuz all i want from them is there exhaust cam lol, but they wont part it out. I might have to get my stock exhaust cam regrind to those specs but have to find a place that would do that for me.

Yeah, I saw your posts. I would buy some turbo cams if they came out tomorrow.

So what you're saying is we're not performance oriented on here? huh? HUH?

If you want turbo cams, just get a regrind.
lol oh and ppl on here is either lightly modded or turboed, there's only like 2ppl on here thats just about fully bolted. The rest of the guys dont want to mess with things internally. I guess cuz they dont really do any races with anyone or because of warrenty purposes.

But guys if you want cams BC seems to be the best so far.

If I was to do it all over again, i would get the JWT intake cam and the BC exhaust cam. You will deff see 10-15whp with that combo.

Werd, I would do the regrind, but I cant afford the down time. One of these days though...

you can just buy someones stock cams and send them out with the GB for 100 for the regrind. Or you can buy theses low compression pistons 8:5:1 http://www.raceeng.com/p-7966-nissan...c890mm851.aspx

When my car was worked I had cams and intake/plenum spacers so :rock: but then I went back to stock so :thumpdown:

Fail.

:bawling:

Good news for you boosted specs and N/A

"The car they tested it on was boosted at 8-10 PSI. They saw 20-25 WHP. They are currenly manually grinding them for 500 for the pair and later this year they will be CNC'ed 100 cams at a time for much less then the 500. After that they are also starting to do springs, and retainers. He said he could get CP to do pistons and the rods will be come later. Right now he said there is more a demand for head work. Also he said they would work for N/A and FI. N/A about 15 WHP 20 WhP w/tune. This is great news. Currently he is out and only made 10 sets. He will be making more if you want them you have to get on the list. To do so Email him and they will be yours first."

that was one of the posts from a person from myspecv, He spoke to the ppl from Brian crower and thats what they told him.

oh man...i think i just wet myself...looks like my goal of 300+whp on 8psi wont be that hard

oh shit after reading this thread, just reminded me that i have cams that i need to install!!!! haha

i think that was alread a given lol

I'll trade up my Nismos for these.

thoses specs look so beautiful, more top end.
I wonder why the lifts are smaller.

I guess the valves don't need to open that much for optimal power...oreo.
