Want to make my VZ SS 5.7 go faster

[Crazykent]

At the moment its got pacemaker headers, sureflo 3.5 inch exhaust with hi flow cats and a growler induction.

I've been tossing up the idea of getting a dyno tune or a stage 1 cam but my problem is i dont wanna get tune and want more power or get a cam
and it be hard to drive around town/chew more fuel/wear out other parts quicker.

Are there other mods i can do plus a dyno tune where i might be happy with it?

Or if im unsure about anything else should i just go straight for cam? Are the issues i mentioned with a cam realistic?

youll get plenty of advise on hear mate, some good some not so good, why dont you contact one of the reputable performance outlets (forum sponsors) on here that are close to you and discuss your needs with them.

Do these 3 things for now and you will see a massive improvement.
1. Ditch the growler and get a Duspeed OTR (over the radiator air intake)
2. Change diff gears to 3.73, 3.91 or 4.11s
3. Get it tuned by a reputable tuner.

This should keep you happy for a while, and in this time you can work out what camshaft you want in the future since there are soooo many cams to choose from

Thats where my power of deduction comes in. I've already been turned off from asking someone advice thats aready trying to sell something, figured i'd just come here and get some ideas from across the 'board' so to speak.

I got the growler for 2 slabs of corona lol been wanting OTR ever since but cant justify spending the money when i've already got one basically for 80 bucks lol

Man i've been contemplating diff gears since someone suggested it years ago but can always find a downside to it. Although ur response is making me think about it again, one step lower should be fine i reckon especially since it's an auto.

And as for tuning if i knew who to go to i'd prob already done it, i live in belgrave, anyone know closest/cheapest to their? i've heard of some paying as low as $750.

Couple of things
1.growler to OTR....you will notice a difference in induction sound and seat of the pants acceleration. You would also get a quicker time over the 1/4 mile with a Duspeed OTR

2. Go 3.73 diff gears since its auto. The rpms won't sit that much higher at 100kph and you'll get into your torque range quicker

3. Also these days, you shouldn't have to pay any more than $1000 (usually $800 to $1000) to get it tuned by a decent tuner

As for a tuner, go and see Chevs Performance in Carrum Downs. There are many happy forum members on here that use him quite regularly....not me since I'm in Sydney (mine's tuned by Sam )

[vzv8man]

Duspeed also have just released a Duspeed MAF otr, however they say you will need a tune with this. Usually the maf tunes are a bit cheaper.

Any idea what the difference between these 2 are? other than the price. Also what about the 3.45? or is that too small of a step?

Your going to need more then just the gearset mate. Bearings, seals, oil, labour to build and R/R etc.

OTR, gears and a mafless tune. Youll be happy for a few months. The growlers are total crap OTR is alot better.

Agreed. Should be able to get the that all done for under $2.5k

Can you break down the costs of each item to get to this value please? I'd like to compare

Thanks

[SSUte01]

I reckon closer to $1500 for those mods. Best value for diff gears IMO is to source a M6 3.46 or Clubby 3.73, if that's what you're after, complete LSD and put it in rather than rebuild the current diff.

[abrowne70]

$1500 for a decent otr, tune and diff gears, i dont think so

A good diff build will cost over $1000 alone
plus $700 for a Duspeed OTR then a tune $800ish depending on where you go

[white lie]

$1500?
Out of interest, how much do you expect to pay for a tune?

For quality work, I would roughly break it down something like this...
Intake - $500
Diff - $1200
Tune $800

So close to the 2.5k figure, some OTR's will be more than others. Even this would be on the cheap side IMO, I can't really see it happening for a grand less but obviously you'll save money using second hand gear, up to you if you want to go down that route. Manuals are usually slightly cheaper on the tune cost too but I'm just talking ballpark here.
