Adding a cam will make the exhaust louder, maybe weigh up your options before removing any mufflers to make it louder or atleast have the muffler flanged properly so if it is overly loud once cammed you can throw it back on to make it a lil bit quieter

Never seen decent brand name slotted rotors warp, but yes can't stand when people coast the brakes

I use stock calipers with slotted rotors and HPX pads in my VZ, Does 12sec 1/4 mile and pulls up fine.

I wouldn't bother with the change, to me its not worth it. For more low down torque I would be taking it to a decent engine shop/builder and asking them too Dial in the cam properly, also having the heads shaved will increase compression and low down torque, but need to be careful with the...

your kidding right? The long duration of the exhaust on aftermarket cams in these LS engine is more common than you think, The volume of the intake runner of an LS3 head is around 260cc (exh 90cc) along with a massive intake valve 2.160" vs 1.590" for the ex. Basically the intake sucks in all...

Driverside Vac line from rocker cover to a Cable throttlebody or for DBW vehicles sit in the intake between air filter and throttle, Vac line from Valley cover to intake manifold Passenger side sonly should have a breather from the fuel tank that connects to intake manifold

LS1's come with 2 types of heads early 853's and 241's, I'd go for the 1.0mm or a touch smaller with original NGK style copper core LS1 spark plug change as its easy as and at least you know what your plugs look like when replacing them after 10-15k

nope not once = Never

save your money as those cams are so close in specs you wouldn't feel the difference - do the diff and relook into this: http://forums.justcommodores.com.au/vy-holden-commodore-2002-2004/250692-should-i-supercharge-my-monaro.html

bob jane used a screw driver to get the weights off one of my wheels, didn't notice until 3 weeks later, they seem to have no recolection of doing it :censored: seems that they couldn't differenciate alloy wheels from steel wheels...

Did the melling pump come with a choice of 2 springs - some aftermarket pumps come with a choice, maybe its running the high pressure spring

lol :nutkick:

Hey Tiesty, Does your glovebox kinda sag to 1 side a little, just trying to figure if all VZ's/calais have this issue

is it using oil? Does it smoke on accel or decel? Checked your plugs lately - how do they look? it could be worth taking off your throttle and seeing what kind of oil build up is in your intake if a lot of oil it will be PCV, Best to pull of intake to clean and do the throttle while your...

Do you now what colour the smoke is?

PCV valve is CLOSED at WOT

i would be getting that tunes AFR's checked for piece if mind

1 3/4 with 3in outlet plenty of different brands of cats depends if the EPA/PO-PO may pull you over which you legally should run 400cell, I run 200cell magnaflow cats, but no EPA/ police defects up here in QLD The Lower the cell the higher the flow

SOLD Please remove

Has your VZ got the 3 window dash, you can reset the L/per 100 so you can actually get the right fuel consumption figures for hwy and city driving

nah i wouldn't think there'd be much benefit in increasing pressure what other mods does the engine have?

Stock N/A 3L Jatco AUTO But u may already have figured that by now

Yea manifold sucks in stock form but so many factors with dyno's, what does the car feel like on the road?? Injectors way too big imo. but thats another story Had cam/heads and a starr manifold on my 304 with VN group A 22lb injectors (stock is 19lb) and still never got to 100% duty cylce

wont be able to register the vehcle with an older motor

Send it back to the tuner they should be able to work the lump out, pushing on the brake may be a little harder to tune out, but most will get it fairly decent

1. Most likely have more power and economy, yes it will wear out your accelerator pedal :driving: 2. no it won't as long as the tune is done correctly. A factory tune is fairly conservative. Tuning actually involves correct air/fuel ratio and adding more timing for greater throttle response and...

With a old holden motor you can't steer past Shane Alex Engines @ North Brisbane or Horsepower Engineering @ mansfield

How did you go with this?

Define decent rpm range? probably better to ask garrett/engine builder unless you know how to read compressor maps

Very nice mate! Whats next on the list?

How old is your battery, they do some fu**ed up things sometimes. also check IAC and TPS

Mantic, Mcloed or LS7

Bit of info and measurements here: Electric Fan Size

nice, heads look nice and clean - anywork done on them?

how is the preload on those rockers? I would have thought the pushrods maybe too small! usually the base circle of an aftermarket cam is smaller than stock! Maybe the tie bars are little higher than stock?

pretty sure they won't

Clean throttle, maf and IAC maybe also o2's need replacing
