Telling VCT from Non-VCT

[SileNceR]

Hi,

Have put a deposit on an AU3 6 Cylinder Engine, wondering how I tell if it is VCT or non VCT does it say VCT on the rocker cover if it is a VCT engine?

these are the part numbers from the block, head... and somewhere else; timing cover perhaps?

WR2A-6090-AC
WR2A-6059-AA
WR2A-6015-AB

if that helps at all..

it shouldnt come down to checking numbers, there is a huge mechanism on the front of the head, notched into the rocker cover..You simply cannot miss it :0)

[Racecraft]

See it sitting right at the front, a HP or standard rocker cover won't fit so it should like the picture have VCT plastered across the rocker cover

[SileNceR]

aha!

its not a VCT then it says Intech 4.0L no angled stuff and its not red

that and its got the small downwards half moon at the front

[Racecraft]

you didnt say it wasnt an XR my bad for the asumption..

The VCT was only on the XR's and luxury models...

Ah cool I wasn't 100% sure I thought by AU3 they might have been standard VCT across the whole range or something

Nope. Probably the least made I6 Falcon engine (well, head really) ever. Its unmistakable, Red, has VCT on it and the VCT mechanism is like the proverbial dogs b....s.

I had no idea what to look for never really studied any AU's either...

[DJM83]

look under the rear ull see and IRS set up aswell indicating a VCT anyway ur paroblem has been solved

[SileNceR]

I'm only getting the motor, not the whole car

Thanks anyway

[DJM83]

opp my bad

[Casper]

What are you going to put the VCT motor into? Are you getting the ECU and loom too?

IS it possible to put a VCT head on a non VCT engine?

Yes , it is possible. The bottom end is all the same across the AU 6's.

hmm My XR6 has a Red engine, but it only says Intech 4.0L.... No VCT logo's..

Your XR6 must be an HP variant , only the up-spec XR6's Scored the VCT engine...Both Damn fine engines!

[DanJar]

So the VCT is better than the HP engine?

Technologically speaking yes it is , but in reality there isn’t a lot between the two performance wise as the VCT motor was paired up with an Independent Rear Suspension system that was 80kgs heavier than the live axle setup that the HP scored so that blunt its performance somewhat. The VCT system was designed to boost low end torque and give afew more KW’s ..... it is apparently abit smoother than the HP so i hear....

Hell Yes. Especially between 3,000 and 4,000 RPM, which was the 'sweet spot' in my AU. It went like the clappers too. The Low Down torque was phenominal, and the high up kilowatts made the T5 option that I took out worth the physio I had on my left leg. What was that you said about yours Casper? :rolleyes:
