Hi
I would like to ask a few questions.
i would like to know the bennifits of replacing the stock standard fuel injector's.
what other upgrades will be needed?
i already have cold air induction.
gettin high ratio rockers 1.9:1
i would also like to know if anyone know's of a place you can get a full high performance pully kit for V6 ecotech.
cheers
Would you be replacing the injectors with new/reconditioned standard ecotec ones or new ones with a higher flow? IMO if your replacing them with new standard injectors you will probably pick up a small amount of efficiency/performance as the old ones currently in it are most likely not all flowing even and have a different spray pattern after years of work and slowly collecting and clogging up with random impurities in the fuel that make it past the filter so I would recommend doing this even for the sake of keeping your motor running in top condition. Upgrading to higher flow injectors it also good but you will probably find that without getting it tuned to suit it will run like a dog and be too rich, especially down low if you put your foot into it, it will have a flat spot and cough and splutter a bit before it gets going (i.e. too much fuel and not enough air). Also depending on how much you increase the flow rate of the injectors you may also need to upgrade your fuel pump to keep up with the demand.
This is my experience from mucking around with injectors on a mates ecotec but others may think otherwise. Hope this helps.
There is no benefit to fitting new/bigger injectors on a stock or slightly modified engine.
You only need to replace injectors if they are rooted or the engine is modified to the point where the flow of the std injectors isn't high enough to supply a safe A/F ratio.

I whacked in some VERY low k's VX injectors into my VS ecotec, runs ten times smoother, even better fuel economy then before, best money I ever spent, keeping in mind these injectors have a bee's dick less flow but spray the fuel better.
cheers guys will take your adivce into consideration.
i am more then likely looking at alot of modifications, to my car, engine, etc.
so if you have any further sugestions on increasing the perfomance of a Vs V6 Ecotec ute.
your advice n knowledge is welcome.
i have a list a foot long of stuff i has to buy n fitt in the new year. as my car is off the road for 3 months due to lose of licnece. so i'm doin alot of work n upgrade to improve my car's performance. and looks.
Learn what your motor is called. ECOTEC, no H on the end. CAI: good on you, you're a step in the right direction. If you want to do injectors go ahead but don't upgrade, replace with newer ones the SAME SIZE AND FLOW or you'll need a memcal burned to suit. Exhaust is a good next step I suppose, just do some research and try not to end up with yucky nasty V6 POS drone like 90% of V6 exhausts out there (including mine).
High performance pulley kit..... I don't think you need to worry about that yet so throw that one off the list for now, probably ever.
Plenty of advice floating around here already mate, there's a brilliant thread on Ecotec modification somewhere, I can't find it at the moment. Maybe some other kind soul will know where it is..
edit: found..... Buick and Ecotec V6 Performance Upgrades

ive heard that a cold air intake puts on 8 kw on but not sure if you have to do more to get that power gain
Is it supercharged? because mace engineering does a 10psi pulley kit for cheap. Im assuming its supercharged if you want a pulley kit if not dont worry bout one. could you imagine the price on a gilmour belt that long. and bigger injectors arent nessecary unless you want to put more fuel in and with more fuel you need more air
And by the way how much are stroker kits worth for v6s and do they do any signifigant increase in power on a super6?

lol........
if you're putting a CAI on because you think then you can say your car has (stock + 8) kw then good for you. With V6s it's not about power dude.. just modify them for efficiency / a laugh. Also the power gain depends on so many things man, I don't know who told you 8kw is the magic number but they're either just saying what their particular car made, which is useless info to you anyway, or they are just dribbling ****.

Power increase with a cold air intake is all relative to the ambient temperature, and how long / at what temperature the motor has been running.
If your car is running hot because you've been thrashing it, and it's 5deg outside, then a front-bar cai is going to be doing a LOT for power. However if you just turned the car on, and it's a 30 degree day outside anyway, a cai isn't going to be doing much at all.
Just having a cai there doesn't give you magic power![]()

hey, so whats the go with a performance aliminium radiator.
they worth a look, i think i saw some around the 300 dollars mark on ebay brand new?
Sorry guys not trying to take this off topic or anything but i removed the rear ressie on my VS Ute and well now it makes a great sound below 3500rpm that i love even if others don't because its only a V6 but how come it goes silent after like 3500-5500rpm? What causes this and whats the best investment a 2.5 Catback or Extractors?
Thanks
Matt
limited slip differential
has anyone got a good website or information on where to get a new or used LDS
Your best and cheapest place is eBay. Next from that, is a wrecker. I picked up my complete brand new LSD centre with 3.7 gears, all shimmed up nice and tight in a full hub-hub setup for $500. The bloke paid $1200 to get it built the previous month (receipts and all) but found a locker with 4.11s two weeks later and installed that insteadlol
You can find great bargains on ebay![]()

You've got a VS ute? An LSD Centre will fit out of a VN/VP/VQ/VG/VR/VS for 100% certain. You just take that diff to a diff specialist, and ask them to put the centre from that, into your car. Should cost $300 for the changeover
And I'm 99% certain that a live axle centre will fit straight into an IRS centre.

If your refering to the front twin piston caliper upgrade, just be sure to look at prices of doing it with a good second hand vt/z calipers and rotors. I got a set off ebay for $70. Cost me $80 i think for adaptor braided brake lines from the local brake shop and $40 for the egg rings to take up the space of the slightly ovesize rotor hub holes in the vt/z rotors. So $150 all up to make up my own kit, alot cheap than the $400-$500 they charge for kits.
