Ignition Leads or High Ratio Roller Rockers? V6

[JSTCOZ]

Hey guys,

Got car serviced today and spoke to the mechanic about getting a bit of power in my v6. Still on P-plates, just wanted a little bit more power to get me by)

I suggested High Ratio Roller Rockers from MACE but he said it won't be worth it at all.

After servicing my car he said that if i replaced the ignition leads it would do as much as the roller rockers and be a few hundred bucks cheaper.Car has done 160,000kms and i don't believe the ignition leads have been changed for a fair while (probably since 100,000 or less, not sure only had car for 20,000). He said the leads would cost $450 as he will test them and tune them on some special $7,5000 machine he bought for it or something -_- .

I know I won't get much power out a VT V6 engine, but I'm not looking for massive gains, just enough to get me through being on my p plates. $800 or so is what i'd be looking to spend on a bit of power.

My main thought was, is this mechanic pulling my leg or not about the ignition leads really making more of a difference?

Thanks for any advice at all guys!

$450 for a set of leads WTF??????? are they made of gold?

$800 = roller rockers, plenum and manifold spacers

Yeah i think he said get performance ignition leads or something...unless i heard him wrong but im sure thats what he said.
You reckon those 3 things will make much difference? cost much labour?

how do you "tune" leads???

[some_guy]

The guy is pulling your leg. Ive never heard of such a mod, if it were available, every boyracer would have it.

Mr_VX has the right combo for yah. Rockers + Plenum & Manifold Spacers will net you good gains.

And in terms of labour, do it all yourself. Mace's rockers come with good instructions from what i've read.

Hense why im asking you guys. Is there any other sort of 'plug' thing on the car that he might be on about? :/ He said he wouldnt want to waste my money installing the rockers for me because they won't do anything for power?
Reckon I could do somethign better with the $800 or so bucks of got floating around for soem power mods on a p-plater V6?

Hmm he does the lead/plug things as a 2nd job thing. Goes around doing them for people he said. Used to be a stockcar racer too... i keep thinkign i may have misunderstood but you guys dont seem to have any idea what he is on about.

I might just do that Mr_VX said instead.

What ratio rollers would you prefer, high or ultra high? Also any idea on power gains it will actually do? And last Q i had was, will it make the car sound lumpier?

you will probably get around 15-20 kw more from all them, and better low down torque like the buirks had

nah wont make your car lumpier , need a cam to do that lol

[MR_VX]

you will get some gains from the 1:9.1 or maybe 1:98.1 and not it wont sounds any more lumpier

[old mate]

your 'mechanic' needs to stfu. he's taking you for a ride if he thinks that more cam lift = no more power.

[JSTCOZ]

alright so that mechanic is full of ####'e.

Would I be better of going for a larger cam instead? Supposabley the labor of gettign it done is an absolute money killer? Would gains be better than doing what was mentioned above?

[MR_VX]

yes you will get alot more gains for a cam. but alot more then $800 to be installed.. plus you would need a full exhaust for a cam

[JSTCOZ]

Whole exhaust system and extractors has been redone

yeah cams look like they could cost almost 2 grand then after purchase and getting them fitted :/

I might just ignore the cam, the 'leads' lol and just buy what bolt on stuff mace has to offer within my price range. I am a hopeless bastard at DIY work though :/

[MR_VX]

nar bud its easy as to do

[one_and_only2004]

when i was making over 300KW on my v6 I changed my leads.

It helped nothing.

Mace manifold spacers and rockers did the trick in NA form. They don't look like much but they work.

[JSTCOZ]

Thank you so much everyone for all the help!!

I will spend my money on spacers and rockers then.
Might do some research on if that throttle body and insulator things from MACE are worth it too and also what roller rockers are better.

[one_and_only2004]

In all honesty I found the throttle body a waste of time, all it did was "appear" to make more power because 1/4 throttle was now 1/3 throttle and so on. These little ecotecs can only suck so much.
Stay away from the 70mm Air flow meters too.

Sweet happy to know! So you'd recommend the rollers and plenum spacer only then? Got any idea on what size rollerswould be better and more punchy?

[ari666]

ill bet!!! if i could charge unsuspecting people 390 dollars for doing nothing, i would have that as a second job too.

[one_and_only2004]

I'd go:

1.98 rockers.
12mm manifold spacer
12mm plenum spacer.

I would then make myself a CAI out of PVC pipe into the stock air box, and then I would call it a day. This is the point where you have achieved the financially viable (I use that term loosely) mod limit - anything else on an ecotec is a waste of time. I wasted a lot of money on ecotecs - my 260kw 6L v8 stock flogs the crap out of my old 240RWKW supercharged v6.

Keep in mind that MACE rockers aren't roller rockers, they're just re-engineered standard rockers. I'd personally used Yella Terra roller rockers - but they're a little bit more expensive.

[thekid93]

i like to know what leads hes talking about?

msd coils and leads wouldnt even be 450....

[DevilDRake]

1.98:1 rockers.
25mm manifold spacer
12mm plenum spacer
69mm Throttle body

Prob cost you about $1000, but it's DEFINITELY bang for buck.

agree, have abit of fun with the v6, but dont spend on the earth on it, because the v8's are starting to get real cheap, ei ls1 for under 10k ...then consider how nice a bog standard ls1 is compare to a tickled v6 ... you can spend alot on both easy, but dont waste ur money and ur time, been and done the v6 thing.... either get a decent turbo happing or the v8 is ur friend

Yeah I'm not gunna go crazy on it because i know it isn't worth it. Instead of tuning my V6 i just got a big LED TV for my room instead...LOL. And now I'm going to save for next 2 years as best i can to get an 8 .

Thanks for all the great advice guys!
