V8 Performance Parts

[MACE]

COLD AIR INTAKE ENCLOSURES

New generation cold air intake enclosures to suit Commodores and Statesmans VN-VY 5Lt & VT-VZ LS1/LS2, which are a direct bolt on drop-in replacement for your existing air box assembly. The kits include an all new air box, airflow meter safe pod filter, along with mounting hardware required for complete installation.

CNC PRECISION PORTED THROTTLE BODY

CNC precision ported throttle body for VN-VT is enlarged to a final diameter of 70mm increasing maximum airflow by 14%. Backed up by testing, gains of around 5kw at the rear wheels are to be had if used in conjunction with extractors/exhaust and cold air intake. A greater power gain can be achieved if more mods have been undertaken such as a larger cam, supercharger etc…

HIGH RATIO ROLLER ROCKERS

High ratio (1.9:1) roller rockers (stock ratio is 1.7:1) to suit LS1 V8’s increase valve lift thereby allowing your engine to breathe much more efficiently resulting in more power.

Hey ScoHar,

We'll certainly offer competitive pricing on here. In regards to the pricing on trademe, considering the exchange rate and the fact that there is no GST paid on the item as it's for export (further keeping costs down), prices probably won't be less then trademe. If you have any more questions please don't hesitate to ask.

Kindest Regards,
Steve

Does it make a difference if I can tele transfer in $AUS ?

Does it make a difference if I can tele transfer in $AUS ?

Sadly it would probably make the price even more expensive because you would have to pay a tele transfer cost of around $25NZ In saying this though we have a bank account in NZ so you don't have to worry about this if you pay in NZD.

Almost forgot can also pay via paypal however, if would be cheapest just to deposit the money into our NZ bank account for any one in NZ looking at buying our products less fees for all

Do you sell brake upgrade components and (Vortech)supercharger accessories? (Idler brackets, pullies, etc?)

Hey NOGEN 3,

Unfortunately we don't sell brake upgrades. In regards to Vortech accessories, we sell the brackets to suit the 5L's and rebuild the blowers themselves but that's about it I'm afraid

can you guys do a twin throttle manifold for the 304 v8???

I wish we had a dollar every time someone asked us this question. Sadly we don't

[Raptorsc]

Maybe sometime you will organize a twin throttle for the 304 as well as a lighter and cooler running manifold

Would be quite an item

We actually started working on developing one a few years ago however we got caught up with other things and it's been on the shelf since

can i please have a price on the ls1 roller rockers

[MACE]

The LS1 rockers are $440 changeover. Bare in mind that they are the highest ratio rockers on the market and provide a genuine gain of around 5-10% at the wheels when used in conjunction with stiffer valve springs. They will still work with the factory springs however to avoid any float top end stiffer springs are needed. We can supply quality PAC 918 springs to suit with these rockers for $220.

[Commydoor]

can Mace supply roller rockers that are straight bolt on without adjustment that fit under the standard covers on a VR 304 and if so what is the cost delivered to Beresfield 2322 and are they in stock. thanks, Jim.

I don't suppose you'd have any dyno charts to go with these?

I was looking at going 1.8 a while back, but the consensus amongst people who'd tried them was that they didn't have much gain on a LS1. Would be keen to see how 1.9s do.

Also how high can you go with a stock cam before you start causing interference?

Interested in the 70mm throttle body

Hi Commydoor,

Unfortunately we don't have rockers to suit your car Your best bet would be to try YT or Crane cams.

We have dyno graphs. Hopefully I'll be able to scan them and have them up here on the weekend.

Not only this but the part throttle response is much better with these rockers then the factory items resulting in better driveability

These rockers generate around .550" of Lift on your stock LS1 and 2 from memory, which is small cam territory, without the expense

In regards to the max lift that these heads can take without machining the valve guides etc is over .600" however I'll have to get clarification from our head porter.

Hi ducker85

In regards to your questions. Ordering one of these can be done via email or over the phone. The price is $220 outright or $190 changeover.

how did you go with dyno sheets for the roller rockers?

[MACE]

I do apologise haven't gotten around to it yet

Another reason why they're not only also is that we don't have any in stock at the moment

better get some, Or yella terra will get my coin...

I've been keeping an ear open about 1.8 rockers, word on the street is that there really isn't much in them by way of performance, certainly not to the same extent that there is for Ecotec rockers.

I'd like to see charts for the 1.9's, to see if they fare any better.

There was a bloke on this forum selling a new set of YT 1.8's for quite a good price (about $500 I think?) he might still have them for sale. From what I've heard though, they are only really good for quieting the drivetrain thanks to the roller tip.
