my first car

[brentbrah]

how can i tell if it is a alloy tech or eco tech? and what kind of exaust would give it a deep tone?

[Nic92]

i think alloytech are up to VY's and eco is vz+

[WogBoyz]

vs to vy have ecotec, vz and up have the alloytec

Yours being a vy would be the 3.8 ecotec

[brentbrah]

alloytech are 190 kw? and ecotech are 152 kw. so ive been told. there must be a simple way to find out by looking in the engine bay?

[brentbrah]

alright thanks mate

[WogBoyz]

the vzs i think have the 170 or 175 and the sv6 vz have the 190kw, vs - vt ecotec has 147kw ecotec, vy and that have the 152kw ecotec

wiki has all the info

[Nic92]

otherway around haha thats right

[brentbrah]

what are a few simple things i can do to up the power/kw ?

[aaronevolution]

Torque is better than kw

[ozirisxx]

Cai - $450/$600
catback - $300/$600
ecu tune - $550/$900
hi flow cats - $300+
headers/extractors - $450+
otr - $500/$650

Alloytec

Ecotec

In terms of performance. Save your pennies and upgrade your rockers to a higher ratio such as 1.9:1 or higher. Mace Engineering or Yella Terra supply these upgrades for about $600 to suit the VY. CAI on a V6 I wouldn't bother. Money better spent elsewhere. This goes too with hi-flow cats. Extractors will be beneficial but not really a priority until you are producing more power at the engine. I'm not sure why an OTR and a CAI were recommended by the same person or why OTR was even suggested seeing as OTR is short for OTRCAI which stands for Over The Radiator Cold Air Intake, an item not applicable to the ecotec engine.

I would recommend doing these mods in this order:
Single 2.5" catback - $200+
High Ratio Roller Rockers - $600
Mace manifold Insulator - $150-$220
Mace Plenum Spacer - $150-$220

This will cost around the $1100-$1500 mark and will increase overall power by maybe 15~rwkw and improve drivability significantly. Hope this helps a bit.

Don't go nuts with a V6 though unless you fully plan on going for big power later such as FI. Even then I'd personally save my money and buy a V8 when I could. I'm currently on my greens and am planning on buying myself a V8 for my 21st.

$600 camwould get you more alone than all the above mods, and eve more with them

[DUK13Y]

To support a cam upgrade you need a fatter exhaust, possibly greater intake and a tune making this a much more expensive venture. However, you are right when you say it will get you more power.

Yer I agree, glad I didn't get flamed. But all the other mods by them selfs will just turn the cam into a bottle neck so you may as well get the cam first coz you'll start out with more power and get the other stuff later. If he spends a few hundred on the intake and what not he'll be disappointed

Yeah sorta. The way I see it is it's always best to do your supporting mods first so when you get the cam, and tune to suit, the tune will be perfect. If you do cam+tune first, the car won't really like it as it changes the way it runs, requiring the larger exhaust, etc, rather than it being an option. Also when the supporting mods are installed after the cam, you will need to retune, adding another $800~ to the final price.

Yer I get ya, good point, I guess I'm lucky getting tunes basicly for free, i guess the best option would be to do it all at once

I have a vy v6 and I will be doing high ratio rockers and a lukey cat back exhaust. What benefits would I see from these? Also to the op, don't spend alot on mods for an n/a v6, unless your looking at major aftermarket mods like super/turbo charging stick with simple, cheap ish mods to keep you happy with your car which its what I'm doing :-)

Based on your own words.

Ditch the High ratio rockers and just go the lukey cat back.

Look at it this way. Unless you'll need a tune after the mod, there's going to be bugger all power increase. save, get hr rockers, a cam, mabe a stroker, and whatever exhaust you wanna do, put it all on at once, tune, then you'll get a decent increase. You shouldn't need a bigger throttle body or filter unless you start porting the head.
I've seen engines on the dyne with stock filters absolutly filled with crap, and they still make full power. The stock filters are good enough until you do some real mods like boost or a full induction-exhaust set up
Same with the throttle body, if holden found that the v8 throttle body was that much better than the 6, they would've put it on
