Looked at and heard some modified cars - definately getting the bug. My 04 VXR is currently standard.

Question is though should I go for

a) Wortec Focus + AVO
b) Wortec Serious

Whats the consensus out there????

It really depends on what you're after. If its just "vocals", then you can't beat the Headers, they are totally outrageous.

If its power, then start with the Focus pack (will still give a good vocal as well)....The car will still feel much more powerful and will then give you the opportunity to move up to the "Serious" once you feel the extra power is no longer stimulating. If you went straight to the Serious, once you've gotton used to it, yoou've not really got much left to go for other than forced induction (or you could start doing some serious internal component mods)

The focus pac includes the headers too I think? Therefore I would go with that plus the suspension as the serious pack includes the 1.8 roller rockers (standard is 1.7) which aren't much good to anyone lol! After that Forced induction is the next step and possibly some AP racing brakes.

Not according to Wortec www, not for the 04 VXR... it is included for the 04 CV8

You guys forget heads and cam is a worth while mod.
Stock no mods is usually around 230rwkw and maybe 250rwkw for ls2.
With heads and cam you can break the 300rwkw with supporting mods.
A very well done setup will make 350rwkw in an LS1.
Sure over that then you are talking forced induction.. or larger engines.
But dont dismiss cam only installs for a good bit of extra power up to around 270rwkw without breaking the bank.
You might find you will even give a few low boost superchargers a run for their money!

Guys in oz run 11.4x sec quarters with small cams. Oztrack for one.
Plus you get a nice cam sound

Just to back-up,

What ringram says have a read of this site. Dan has about done it all with his CV8 (Monaro) and also helped develop EFI-Live so definately a worthwhile read here:

I would add the LSV supercharger for £3k as it increases power to >500bhp

I dont think either of the above would get close to that

the vxr has upgraded decent quality shockers and matched springs so i wouldnt change them on this model

Focus and AVO's.

Sorry, forgot to add brakes of some description, whether it be on 05 VXR upgrade, the Wortec interim or full AP's. 04 cars were lacking a little.

04 VXR brakes are same as standard 05 model cv8 brakes iirc. Are the 05 and later model of VXR brakes really that much of an upgrade for an 04 VXR?

05 VXR brakes are a marked improvement over 04 VXR ones. IMHO

useful to know caspy re the 05 VXR vs 04 VXR brakes. That being the case have Wortec actually launched their "interim" package then. Havent noticed anything saying they are available yet.

They have. Havent got full details here, £1200 i think. Pedal feelis slightly better, but, fade is markedly less pronounced.

I will get details and forward by PM on Monday

cheers I'd appreciate it. Now here's a tricky one though - are the Wortec interim brakes "better" than an 05 VXR standard brakes?

Yes. Not quite the initial bite of the 05's but better fade properties.

The new pad compound arrived on Friday so we can confirm prices next week.....

The upgrade will bring 04CV8 brakes up to the same efficency as the 05VXR brakes BUT the pad compound we now have can be fitted to 05VXR brakes to make them better still......

I'd love to go for a cam and maybe heads. The sound alone with a lumpy cam is probably worth it, but throw in the gains you quote and it looks even better. The thing that puts me off is that I don't know what's involved in getting a tune done with an unknown cam. Or even if there is anyone in the UK that offers such a custom tune. I can wield a spanner but tuning is a step too far.

BTW I think this sounds great.

Where are you located Jimb0?

There are sponsors who can do cams. I did mine myself with efilive with excellent results. If you were local Id be up for giving you a hand with the cam swap for interests sake as well as the tuning side. Ive done a few things like swapping brake disks, installing rip shifter, swapping injectors, porting throttle body etc. So should be semi useful on that side and have done a few tunes including my 282/286 cam. I even swapped a cam over in a 400 chev I used to own in NZ. Flick me a PM if you are interested.

Tell me more about about the interims. What does it involve?

(sigh - another variable)

Hi Steve

Based on Wortec's earlier post, I will confirm details, spec etc and PM you on Monday.

PS

I have a BRAND NEW set of 05 VXR calipers, pads and discs that will be available to the highest bidder!!!
