im looking for a set of cams for my b18b, i have been searching on here, and the talk has all been about CROWER 402's and 403's... but i get the idea that these arent really turbo cams... who else makes good turbo cams??? they will be used in a street driven set up, with around 400 whp

also, will a cam like this have a lumpy idle, and not sound stock anymore???
i remember the way duc's car sounded in that ground zero video... it was mint, but i dont think i could get away with it on the street

Running Crower 404's in a friends turbo setup, and they work great. They have duration numbers that arn't even as high as stock ITR cams, so why does everyone wet themselves when someone thinks of using a cam like that for a turbo app? They're basically Civic SI cams with a lot more lift, and everyone says that the GSR and ITR cams are better than the B16 cams for turbo, which just adds more duration on top of that, so why are people afraid to run the 404's on a turbo setup? Beats me.

b/c they are a constant high lift. and the idle isnt the greatest. with the ITR/GSR/SI cams they have the vtec, which allows them to run on a lower profile/lift in the lower rpms. Which is the point of vtec.

So what? Are you building a turbo car to make power off idle to 4500 RPM's, or are you building it to build nut-busting power from 5000+ RPM's? Idle quality at 1200 RPM's is perfect, doesn't stall or anything like that, and makes great power with a titan61. It bothers me that people insist that these things have bad idle, but most who say that have never driven, rode, owned, or even seen a car with these cams in person before.

arnt 404's more for a NA setup? with agressive cams arnt u leaking boost?

Rockets L21 cams for the B20 and LS own, just ask Jalopy SiR about em. He made 20whp with cam gears and tunning.

see the 404's are even bigger... crower doesnt even reccomend the 403's for boost, but some people sware by them... im confused

i also have cam gears so i can dial out a bit of overlap.....

im not too concerned about the power level below ~5000 rpm... but i dont want the car to idle like **** at 750 rpm.....

i was thinking abot the same thing... putting bigger cams in a vtec engine is not a big deal, becasue at idle its on the low lobe.. which is probably nearly stock... then in vtec thats when the new cam specs come into play.... a non vtec engine has to deal with that lumpy cam spec at idle...

your friend who is running the 404's that is in a b18b i presume right???

blaze, it says on rockets site that those cams are only available with the purchase of a valvetrain....

thats not gonna hapen... i have a rev valvetrain already

By leaking boost do you mean overlap? Yes, the crower 404's have more overlap than the stock B18 cams, but does that mean that they're terrible for power, and worse than stock B18 cams? No. HKS makes TURBO CAMS for Supras, SR20DET's, and DSM's with 272 degrees of advertised duration. The Crower 404's? 249/251 advertised. If HKS is making cams with MORE duration than the Crowers that are specifically designed for factory turbo cars, do you really think the 404's are going to be that bad? As I said before, ITR cams have MORE duration than the Crower 404's, and lots of people are making power with ITR cams, so if "leaking boost" was a problem with the Crower 404's, wouldn't ITR's have a problem "leaking boost" too? My point is, don't belive all the hearsay. Crower 404's WILL make more power than stock LS cams or the crower turbo cams on an aggressive turbo setup, period, without a doubt. There was a link posted to an HCI article where they built up a turbo B18C1 motor. Sleeved to 84MM they ran Skunk2 Stage 2 cams, and made 650 horsepower. Most people on HT would **** their pants if you told them you were going to run cams like that with boost, and they'd say it wouldn't make **** for power, but they don't have anything to back it up.

In my friends car running the 404's, he idles perfectly fine at 1000-1200 RPM's, it has a little burble at idle but it doesn't sound like a muscle car with a huge cam or anything. He replaced the crower turbo cams and put in a set of crower 404's and took me for a ride, and it felt like he turned up the boost by several PSI, the SOTP feel was very noticeable. His car runs great with them, I say go for it. If you can, put your car on the dyno with the stock cams, take a few hours to swap out the cams, and dyno it again without changing anything. A good cam comparo would be nice.

anyone else???
