lumpy cam?

[j-rad]

been doing allot of looking at lumpy cams, do i need to do any major work to my engine to be able to put one in at all like computer work? also who makes one for the 3.8 eco engine

[wraith]

Urgh not another person who doesn't know how to search. Where do I begin. Well you have Wade Cams, Crow Cams and Mace Engineering. No idea why you would waste the money camming a standard 6. If I was you and you really felt inclined to get some more power just change over the rockers, full exhaust and a tune. Cams can turn into an expensive exercise.

[j-rad]

sorry, yeha i had a look at crow cams, would i need to do my valves aswell?? who can do the rockers?

[pjdm1980]

You could just do rockers, cheap way out of it.

im not really after proformance, i just want it to sound awesome as haha so i was going to put a lumpy cam in it??

Movies over, back on topic now.

Such a big waste of money to chase something that will never happen.

[j-rad]

haha ease up, i got told a lumpy cam makes it sound different?? and improves proformance?

If your set on it mate, than here you go, COMP Cams to suit V6 Ecotec - Mace Engineering Group

There is a video of a car with the stage 2 cam on that page. I have the stage 1 cam, and the exhaust sound is almost the same as the factory exhaust.

Just keep in mind a cam change is not just a matter of slotting in the cam, you will need new valve springs, retainers, collets, valve stem seals, lifters, maybe pushrods, new cam bearings, and probably a new double row timing chain.

Now I know some people will say not everything there is needed, but it is all the stuff that I would change just for piece of mind.

Oh and if you go the stage 2 or 3 you will need a torque converter to match or you won't get the most out of it, and it will take off sluggishly.

And if you want to do that to a V6 then go for it. Not everyone has a V8. Licence probably dictates what you can drive. Just try cat back exhaust and see how you go. Remember the louder you go the more attention you attract to you and your car

Drop the idle 200rpm - lumpy idle achieved.

Lumpy cam making a Ecotec sound awesome is like putting lingerie on that 200kg heffer down the road and hoping it'll make her look like a super model. No matter what you do - it's not going to happen.

haha ease up, i got told a lumpy cam makes it sound different?? and improves proformance?

Different: yes. Good: No. Improve performance: it will be marginally less slow than before if you do it right, do it wrong and it will be slower.

Lumpy cam will probably make u feel like you are going backwards, if money isnt an option get it dyno tuned and go from there coz youll need head work exhaust, computer and upgraded ignition, putting a lumpy bump stick in a motor is a waste of time without matching the rest of your top end to make it wirk youll just waste fuel.

[The pig]

Ecotec sixes dont and wont sound awesome at most theyll sound "throaty", if your only after a good noise and your licence isnt a restriction look to getting an eight. A conversion these days isnt a bank breaker but hey mate its all up to you and your wallet. De tune the ecotec to run like a pig and rip yourexhaust off from the diff thatll shit the neigbours off and the cops so i wouldnt do it personally.

[CHA53R]

Just put a poker card on a spoke if your mag, will sound like a motorbike and gain you serious rwkw. lol speak to mace they should be able to help. I'm going cam soon your looking at a couple grand for parts and install. But you only want it for sound my advice is buy a v8.

[GEN3RATD]

what about those ghostcams if you dont care about power.

[Brett_jjj]

Ive seen heaps of so-called performance cams that either wear out quickly or dont do what the makers claim. Id contact wade or crow cams etc, these compaies have been doing camshaft work for years now and will steer you in the right direction with your needs...These places usually cost a bit more than the dodgey places, but your also paying for the years of experience these companies have grinding camshafts, which is well worth it I reckon....

By definition a bigger cam will wear pretty much the entire valve train faster due to higher lift, aggressive ramp angles etc etc etc. Not to mention how most of them are driven. Of course the quality of components, assembly and frequency of servicing all will have a big bearing on life as well.

When I said "wears out quickly", I meant Ive seen them wear down the cam lobes and chop out the cam bearings in like 20,000 ks of being fitted..And Its always the cheapie cams that seem to do this. Ive never seen a wade cam or similar have this shit happen, unless it was installed wrong or fitted with the old lifters.

This, i was quoted a couple of grand on top of the cam to get the cam changed over. I've got YT 1.9:1 rockers, full exhaust, modified intake (still needs a tune) and the VX goes a lot harder now.

Cost me $1500 to have the heads and can changed on mine - obviously on top of the price of gear. Ended up being a 4K job for 10hp more than a mate with rockers.

A lot of people just throw in any old camshaft bought from the cheapest place that they can find, and they end up being disappointed with the results. Ive seen it all a miillion times before. You firstly need to talk to a camshaft specialist and tell them what YOU want from the engine, like do you want low down power, or mid to upper range power etc, they will take into consideration what other mods that have been done to the engine, and they will then work their magic and grind you up a suitable cam. Theres no way Id pay that much just to get a camshaft fitted, thats just ridiculous. And to only end up with 10 hp more than hi lift rockers give, the cam must have been near on a standard grind, or was just one of those cheap bodgey "one grind will suit everyone" cams I mentioned..

[wraith]

If you do it properly soon adds up. Lifters timing chain etc etc.

[Brett_jjj]

Buying the parts is one thing, and it does cost a fair bit, but theres no way Id part with $1500 just to get it installed.It shouldnt cost anywhere near $4000 just to buy and install a new cam etc..Especially when you end up getting only 10 hp more than a guy who has just got hi ratio rockers fitted.

[wraith]

Yeah agreed I got quoted around 2k parts included when I was looking at doing my old VR V6. That was cam and double row timing chain.
