Im thinking about getting crower stage 2 or 3 cams for my 97integ ls. It says to expect around 30 horsepwer, i wanted to see if anyone knew much, or have them. Also if there is anything bad about them? I'd like any advice also.

-god made turbo lag, so the v8's could catch up

 

i have crower street/strip cams in my supercharged ls and i love them

 

If you are turbo, then you don't want 'em. The amount of overlap those cams have, will actually hurt performance on a turbo motor. Supercharged motors it will help, since there isn't nearly as much exhaust back pressure as a turbo motor.

 

not true. Overlap is a issue but with tuning you can they can help the overlap. Some LS turbos are running crower 404 cams and getting VERY good numbers!

Theres a thread on here about 58 pages long about ls turbos... read some of that stuff

 

really?? damn, I might have to look at that ****, cause I'm going turbo b20-VTEC.

 

not to jack your thred but how much does a set of 404 cams go for whats the part num

 

they suck

<-------- getting the 62402T-2

No!, not for our LS motors there not. But like the GSR and B16 cams are good if those guys keep them stock. Of corse on FI applications.

 

I like my 403's, currently using nitrous with them.

 

don't bother with 403's. not worth it for the money. gas mileage isn't better than 404's by any amount that matters, and performance is way less. most people i know who got 403's wish they bought 404's instead. as for power, expect ~10whp without tuning and ~30whp with tuning.

as for big cams + turbo, it's all good, but you have to understand that they will reduce power down low just like an N/A car. most people say small cams for boost b/c they want boost faster and more low end. now as long as you're running close to as much intake manifold pressure as you are having in exhaust manifold pressure, big cams will be awesome for boost. just make sure you have a good turbo manifold and big exhaust and it will be a bat out of hell. oh, and just like N/A, don't go psycho on the size. don't get 405a's or something for a T3 60-trim turbo, you know?

 

Im thinking about getting some 404's, i heard they make power later than the 403's though.

 

I've heard great things about Crower.

 

i've seen a few 403 dynos and a few 404 dynos, and the 404's seem to make more power basically everywhere than the 403's, except maybe on a seriously ported head. but for stock head casting or mild port work the 404's will make better power everywhere above 2500rpm, and who cares about under 2500rpm? i'll take the +10whp up top and sacrifice a few under 2500. even from 2500-4000 the 404's are better, not equal to the 403's. don't let anybody talk you out of them unless you want to go slower for your money. or unless you want over 200whp, in which case you'll need to go bigger than 404's. 404's will probably only get you to 190whp, maybe eek out 200whp.

 

I agree with Tegman. The dyno on the 404's have more of a power output throughout the whole powerband. I would say the 404's is the choice to go with IMO.
