Just installed a stage 2 crower cam in my d16z6. When I cranked it, the motor idles rough/lobs. I was suggested to change my retainers and valve springs would fix the problem. Someone else said chance IAC. Both of these suggestions are from mechanics. Can anyone help me out?

Btw, I plan to get it tuned soon. And by the end of summer, slap on my JRSC that I have in the garage, running 10 psi all day. SO ya'll know my long term plans. Peace.

 

It idles like that because you don't have a tune. Changing out the springs and retainers won't help that any. Replacing the springs and retainers is to prevent damage at high RPM. You can't just throw parts at a car and expect it to perform. A tune is required on any major part change like that. BTW aggressive cams like that are terrible for forced induction applications. Aggressive cams increase overlap which means you will just be blowing boost in and out of the cylinders....

You can get a basemap ECU from Phearable.net for like $175. Your car will run fine with that until you figure out exactly what you want to do...

 

x2

did you research at all? should of just stayed stock if you were gonna jrsc it. also, if you were gonna run those cams, you should of got springs and retainers cuz they make power past your stock redline. dude, research research...RESEARCH. not trying to be a douche bag but just wanna save you some money.

 

hmoohero-Its a SOHC!

Thanx guys. SO would ya'll suggest that I just remove the cam if I want to go supercharged, and replace it with the stock cam? And if I got a tune with the aftermarket cam and supercharger, it would do no good? Or would that be a possible setup?

I did search for some answers, I was just gettting tired of reading post with cam gears and other problems.

 

i had the stage 2 comp cam in my car and ran it without a tune for a few days, but it didnt idle really bad... are u sure your timing is correct?

 

yea, new cap, rotor, and my mechanic said everythiung looked good, just the iac may need changing or the ecu reflashed. I'm thinking of just putting the retainer and valve springs, supercharger, then tune(I may wait a bit for the supercharger, put I will tune after each upgrade), that sound good to everyone?

 

There is no way that car will run worth a crap until you get it tuned. Here is the crappy thing just slapping cams into a car like that will only get you gains of 5hp or less. My car ran like garbage with skunk2 stage 1 cams until I got it tuned. Adjusting the IACV isn't going to help anything.

How is the computer going to adjust to the changes in the air fuel mixture? The answer is it can't that is why you need to get it tuned. Skunk2 makes cams specifically for forced induction applications. If you supercharge your car with those cams it will be near impossible to put down good numbers...

BTW you can't reflash that ECU you have to get it chipped... Your mechanic must not know anything about Hondas... This isn't a carbureted muscle car...

 

don't supercharge a 1.6 sohc. it takes power to make power with an S/C, and face it a stock sohc will not make enough power to use a supercharger effectively. if you want power out of any d series engine, you have to turbo it

 

Well. I do plan to tune it no matter what I do. So if I put the s/c on with the cam, no other parts, and tune it, will I expect more benefits than a stock cam?

Btw, I will never go turboed, too boring for me. And yes, my mechanic is more of a muscle car kind of guy(even though he drives a turboed mr2).

 

Turbo is boring, so you're going with a supercharger? The supercharger runs off the crank and uses power, the turbo runs off exhaust gas and creates little drag. So tell us, how is a turbo boring and a blower isn't?

 

as in everyone has a turbo civic, I want to be different.

 

if you want to be different, then get an nsx swapped civic, cuz everything else has been done many many times. how do you think we got all this information on what works and what doesn't.

if you want to be different, do something custom, something that you have to actually do work with, rather than just bolting in and re wiring.

swap an odessey engine in, or maybe a supra motor. when you do that, you have become different

 

listen to this guy right here. yea, i know its a sohc. it applys to all honda motors. plus, you're doing alot to acheive so little. the money you're putting into this motor is not really worth it. but i guess you just want to be different. my suggestion is to swap in a dohc and supercharge it. theres not that many dohc supercharger out there.

oh yea, if you're are really content on keeping those cams, get a chipped ecu with a more aggresive fuel/air map. ex: skunk2, spoon, mugen, or get it online thru xenocrome or phearable and let them know what you got so they'll make you a custom chip. but dont rev past your stock redline cuz you'll blow your motor...unless you get springs and retainers like i said earlier. you can run like this for awhile until you get your tune. gl.

 

thanx guys. I got what ya'll are saying now.

So what I'll do is just running the cam and upgraded retainers and valve springs and tune and see how I like it. Then if I decide to go with the s/c, I'll put the tsock cam and parts back on and s/c. I bought it from a friend that had it on a stock z6, the s/c, and he said that would be enough for me. I just wanted to see if I could get some more power out of it with the cam. Thanx, ya'll. I'll let ya'll know what path I go.
