I have an LS motor (B18a1) and i have the crower 403 cams in it, with dual springs and such....Now this winter im going to slap a turbo on my setup...and i need to know if i can use the 403 cams? Will it benefit me? or Hurt me?

 

?

 

I would use it for sure,
I'm using Crane 20 cams on my LS setup,
Intake @Cam .260 @Valve .472
Exhaust @ Cam .260 @Valve .472
On a mustang dyno I make 20+hp than with the stock cams, at the same boost(15psi) Ended up with 295whp on pump gaz. I lost a little on low end but give me a lot more of top end. My idle is like an Harley but I could live with that . If you have already a set of crower 403, I would keep them. It can just be better than stock cams.

 

Ok thats 1 vote for keeping them...Any more opinions?!

 

You can use them no problem and with cam gears you should be able to get them to idle pretty well. And ppl have had really good success with them and boost.

 

Ok 2 votes for using them...Keep them rollin in...

 

MORE!

 

i have 63401T-2 in my gsr. i made 50hp more than stock cam without adjust cam gear at 14.5psi(450hp).
But it broke!!!!!!!!!!!

 

So whats your vote? run the cams i have, or put my stock cams back in?

 

it looks like alot of people have broke there crower cams. boosted-hybrid suggested that i should run 402Ts

 

Compare those Crowers to stock VTEC cams - nothing shocking right there, gonna make excellent peak power.

Compare those Crowers to any cam with a ramp angle that doesn't cause the cam to snap into multiple fragments.

 

Im not understanding that? you guys think they will break?!

 

well you have them so use them....the cams will give you power (just like the guy that made 295whp said) but stock cams wont hurt you either. If you want to sell em n make money go for it. i like stock cams

<~~ Stock cams (look at sig)

Now, what do you think?

Seems it's primarily VTEC units, but if they won't yank poorly engineered **** off the market for the good of the market, why give them any business whatsoever? Rocket Motorsports regrinds, Delta, etc... lots of decent alternatives.

 

I wouldnt ever go with regrinds, ive only heard problems...and these cams i bought arent the "old style" crowers that everyone talks about them breaking...

Theres nothing wrong with regrinds....my nissan friends have been useing them for a long *** time and they havent had a problem. just do what you want who cares what we say. If it was me id use em cause im a lazy **** and i wouldnt wana take em out lol.

 

I had 403's before i went to the turbo setup..and I loved them..great power band..a more noticible difference than the CTR's or Comp 57200's..Highly reccomend them..

 

Regrinds without parkerizing/nitriding/surface hardening and a BIG bump in valve spring stiffness = regrind death. If you aren't ignorant about valvespring rates, and have a properly ramped lobes *cough* Rocket *cough* then you don't kill the unhardened regrinds. It's a similar deal with the K-series and some of the early valvesprings for them... manufacturers were making them in popular B-series overkill stiffnesses, not taking into account that the K-series is a roller rocker design with less oilling needed/available, and your valvetrain/cam would **** itself quickly. THINK about what you are doing, and stupid stuff doesn't happen.

The "new style" Crower VTEC cams break, too.

 

Even after that ranting and raving...i still reccomend them..

 

Ranting and raving? Try an engineering/machining/metallurgy background.

As for your standing behind Crower's VTEC line of cams... that opinion is verifiable with a simple search of these forums. I know of two sets that have broken, purchased within the last 6-7 months, personally. Hey, maybe you're right about the "new style" being much better, but Crower is still slinging the remaining stock of their known defective units.

 

My friend runs Crower 404 cams in his turbo setup. Sounds mean, and makes lots of power.

 

Just to clarify im running an LS motor, wich is Non-vtec!

 

yeah go TURBO!!!
i'm thinking about going t3 turbo w/crower 404's, just debating on which fuel managment system to get and pistons to go with..

 

The 403's will be fine I am running the 404's on my LS

 

OK im gonna run them...i just like to see what other peoples experiences are with them...
