Help ! I installed some V-TEC killer cams on my 95 LS. the only other thing I have done is an intake. the problem I am having is that when the motor heats up it idles very lumpy and dies most of the time. I don't have the money to buy cam gears so I can tune some of it out untill I rebuild the motor. Is there any other way to make adjustments to the motor so it won't kill all the time.

 

u will have to spend large coin to get that car running good

 

Do yourself a favor... put the cams back in tthe box they came in. Wrap 'em up nice, and put them under the Christmas tree. Work on your car for a year, and maybe by December your car will be ready for 'em.

 

I didnt know know you could use those cams on a non-vtec engine.

 

I know there is a lot more I need to do on it and I have thought about just taking them back out but I really like the top end they give me. isn't there anything I can do for the time just to help the idle problem?

 

true that. you don't have enough in your engine to use those camshafts correctly. it's like buying a $2000 dollar scope for a 20 dollar bb-gun. sure it'll "work" but it won't work very well in conjunction with the other parts in your engine.

 

they are the original cams out off the LS that have been ground flatter on the lobes so there is some overlap between the intake and exhaust side

 

OK I know I am getting ahead of myself with the cams but I got them from my shop manager and he ran them on a 91 teg, well OK he ported and polished his head and a few other things but it was pretty close to stock. if he was still here I would ask him but he is not and somehow he got it to run smooth enough to not die at idle. I plan on rebuilding the motor hopfully this spring, uping the compression to about 12 to 1 and putting the cam gears on it to help better tune it. I also will get the exhaust and p&p the head so it will get done soon, but I was just hoping there was some little trick that will make it run at idle

 

If your intent on keeping the cams in, then you could try upping your idle to around 1500rpm or whatever level allows you to idle without dying!

 

what kind of valvesprings/retainers are you using on those cams...and what are you revving up to?

 

i am using the stock springs and retainers and the rev limiter is stock at around 7100 rpm. I plan on getting ahold of rocket here on HT to get some better springs and retainers. after I get that then I will have my ECU reprogrammed but I am not sure how high I should go to keep safe. any ideas ?

 

Going out on a limb here but I always thought that when you put aggressive cams in any motor they caused it to have a lumpy idle. I'm thinking of built muscle cars that idle like **** because they have high overlap cams. It's just a side effect of the cam profile.

 

ya, I know they will always run lumpy, I kind of like that though. when someone pulls up next to me they think I have a peice of s@#* and they want to race so they can say they beat an integra in their civic with just an intake, HAHA. I just hope there is some way to keep it from dying as much

 

man you need to upgrade the valve springs and other top end **** before you put crazy lobe cams in your car. Plus go 2 your local shop and have the car dyno tuned and adjusted. Then go out and kick a type R in tha nutz

 

dude it idels really rought and seems to die is because you are runnning very veyr rich at idle. u need to get a safc or some sort to lean it out bud. or you can decrease the fuel pressure a lil with a fpr but i would not recommend that cause you'll then be running lean at the top.

 

This is a long shot, but after I installed my cams my car died on me twice during the 20 minute "break in" period (run the car at ~2500 rpm). After a quick ECU reset everything was good to go.

Mind you my idle is still pretty rough, and it does get very low sometimes (ie 200 rpm) but has never died out on me at a light. I do have MANY more mods than you, though.

HTH,

You can adjust the throttle stop screw, underneath the throttle return. This will prop the t/b blade slightly open. Also if you haven't done so already remove the throttle body and slot the shear screws on the tps. This mod allows you to make slight adjustments to the tps voltage. After you move the throttle stop, make sure the tps voltage is under .50v when the throttle is closed. You could also enlarge the idle adjustment hole in the throttle body(small increments, you can always go larger).

 

VTEC killer cams are for a VTEC head. They will not fit in your LS. I call BS, or you dont know what you are talking about, oh wait, you obvously dont putting big cams in a STOCK car, yeah way to go

 

i am very skeptical as well but i am not 100% sure they are not compatible..so cant really say anything. but either way, with that stock block and no other significant mods, those cams will probably cause a loss of power rather than any gain.

 

Yeah, unless he has a VTEC head, theres is no way to make those cams fit in a non-vtec head. They remove the VTEC from a vtec motor, hence the name

 

These seem to be home made vtec killer cams, therefore they do fit.

 

Well they are not VTEC killer cams. They are regroind stock cams. Not even close to the 10k RPM potential of the real VTEC Killer cams

 

more like 12k..and i think what he meant to say was that the vtec killer cam is essentially an LS cam regrind..therefore enabling it to work. it does remove the vtec system..but that is not enough evidence to say it would not work because the LS does not have a vtec system to begin with. but i don't think it would work.

 

so if They are regroind stock cams from an LS, how are they VTEC killers? You have a NON-Vtec cam from a NON-Vtec engine.. How exactly are you killing VTEC when it isnt there to begin with?

 

Would you prefer the name "you-never-had-vtec-and-you-still-dont-have-vtec cams?"
