Im gettin the Crower 403's non-vtec cams soon for my b18b1, right now I've got I/H/E. I've of people runnin them without any valve train upgrades as long as they keep the stock redline, which I plan to do. I was wonering what else do I need to get with these, I know cam gears but what kind of tuning system?

 

adjustable cam gears probably. i'm pretty sure you need adjustable ones for tuning purposes. for tuning you can get either an apexi safc or a hondata unit. the hondata is better but more expensive.

 

free up, i'm in the same boat as u. i am also going to get crowers, and have the same upgrades

 

I have the crower 403's but im about to take them out for a greddy turbo kit. They run pretty well w/o tuning. You can use them with the stock valvetrain just dont rev past 7k. They idle well but its good to have atleast a fpr and fp gauge to lean out the idle a bit b/c it tends to be rich.

do you need a fpr if you have it tuned?

 

what did your ride feel like after having the 403's put in? what else did you have the time of them being installed, i have i/e just trying to get alittle info how the power from them feels

 

yeah im also interested in purchasing a used set of 403 just to make driving a bit more fun.
my question is, is it worth it? can you feel the difference in power?
And to answer Hondateg95 question, i think you'll need the 84162- springs and retainer kit to go with the cams.

 

The 403's are great and yes you can tell a difference. A friend of mine with i/h/e/ dynoed at 128 whp. My ls with i/h/e, no cat and 403's untuned dynoed at 143 whp so i guess do the math. Tuned with hondata s200 my car put down 148 whp and 124 wt. I am also using them on stock valvetrain but i still have stock revlimit. I picked my cams up used for 300 so its a good bang for the buck A downside to these is that they make your valves very noisy, it sounds like you constantly need a valve adjustment even if you set them to crower specs(common w/ the 403's)

 

so if he gets the 403s.. that'll run him just over $300.. and then he would have 2 get the valve springs and retainers for another $300.. so thats over $600 right there. does he have 2 upgrade the springs and retainers even if he stays at the stock redline???

anyone know of cams that dont require upgrading the springs and retainers? lol

 

If you are keeping the stock redline you will be fine.

 

does it matter if your engine has high miles on it for the valvetrain ? say over 140k?

 

With the 403's I recommend the Crower Valvesprings since they are only $185. You do not need the Ti retainers unless you plan to rev the hell out of the motor(8500+, which you wont be).

As far as tuning you need Adj. Cam gears, an FPR, and instead of Hondata, I say socket the ECU and run Uberdata or Crome.

 

I have run the stock valvesprings for over 5 months with no problem but you can only do this if you keep the stock redline. It would probably be advisable to get the crower springs but im crazy and decided not too. With the hondata s200 i was able to pull another 6whp and 2wt from 5500 to redline with just a basic a/f smoothig and advancing the timing 2 deg.. There are many different tuning choices to use but i must say that an advanced system such as hondata, uberdata or crome would be the best to use .

 

prolly a stupid question but if you have any kinda of upgraded cams, springs and retainers, that means you pretty much have a built head or would have to get a p and p to have a built head? i knwo its a stupid question

also i cant find this info anywhere but does any one what a stock ls with mods puts the wheels?

Has anyone else experienced this (noisy valves) with the 403s?

i have, thats for sure! My friend keeps gettin mad because i keep askin him to bring over his feeler guage for a valve adjustment. A valve adjustment that i swear ive done 10 times in the 3 days the motors been running, lol.

IMO, my car doesnt have very much kick at all, and i have CTR pistons, crower 403's, DC 4-1 JDM header, Blox IM, fidanza 7.5 pound flywheel and more...

then again, i am running the stock exaust (bottleneckin bad) and stock ecu (Hittin the rev limit like its the thing to do)

so far im not impressed whatsoever but we'll see once i get my other stuff i need to get.

 

I dont feel very much kick from my 403's either. Thats why im going turbo this weekend.

i just cant do it to my daily driver, i cant go turbo... i dont want to deal with it. Some say its nothing but IMO it is. But good luck turbos are always a plus just not something i can do with CTR pistons lol

 

Yeah, with my last turbo setup i was careless and almost blew my engine. I have learned alot since then and hopefully it will go better this time.

You can say that for sure. I ran the 403 and later the 404's on my Teg. IMO if you are looking for power go for the 404's. The 404's are awesome. With the 404's I would recommend the valve springs (to pervent valve float at high rpm's), cam gears, FPR, a good I/H/E setup, and an AFC (to smooth the AFR).

if i were u i would leave the 403s in the car when u turbocharged. someone on this site is running the 404's on 6 psi and he ran 12.7 in the 1/4 mile in a DC integra. at 8 psi he ran 12.4's i think. u will gain more HP with the 403's and boost than the stock cams and boost

i have 403's and P30 psitons right now and im making 150whp tuned by me with uberdata. u can definitly feel the kick after 4K rpms. but i need more HP so im go n LS/VTEC

 

Cool, i guess i'll give it a try.

anyone know what chip i should get or where to get it... im lost when it comes to ecu mombo jumbo

IMO chips are useless (unless you want to increase the redline). I would go with something like hondata/uderdata or at least get an AFC.
