EL Engine Enquiry

[ED_Boy]

Hello everybody, i recently bought a 97' EL Falcon Futura 5spd nd i heard that the last of the EL's got the AU motor in them, or a hybrid between the two, is this correct? and also what are the advantages of putting an XR6 head on the 4.0L thats in it?

any help would be helpful

[Jason[98.EL]]

being a 97 you would not have the hybrid

i have a 98 and it is a hybrid and it a **** of a thing i cant get a normal wade or anyother grind for it 400plus for a cam

I wouldn't mind knowing if it's true that the last of the ELs had AU motors.

I have a 98 model EL...I'm dead sure that's the last cos AUs came out in 98

hey, what colour is it, sounds like mine 97 EL Futura 5 speed, ive still got the standard head but i did put an xr6 cam in.
seems to go ok.

[335JET]

the motor is a mix between EL and AU, hence there known as hybrids.
they have an EL bottom end and AU head.

History 101

In January 1998, the 'hybrid' six was introduced to allow the early conversion of many of the Geelong machine lines to AU specifications. Externally the engines were identical to the earlier EL Falcon engine however featured full AU specification blocks as well as the AU's low inertia valve train.

Unfortunately this did not extend to the AU's head, head studs or head gasket so these engines are still subject to head gasket failure.

This change did however involve changing the normally parallel valve springs to the newer conical AU items requiring new tools when servicing.

The valve stem seal was also redesigned in these engines to accommodate the thinner stem of the inlet and exhaust valves. Included in the redesign was a new installation specification for the valve stem seal.

The block change necessitated a special crankshaft to be made, with large main bearings to suite the AU block and EL size big ends to allow the EL spec conrods still to be used.

The crankshaft can be identified by the letters 'VR' cast into it verses 'WR' which signifies a full AU spec crankshaft.

Great info Rmack!

I believe one must be very careful when installing an aftermarket cam in the '98 EL sixes.

[XR6_661]

Do the hybrid motors have a greater power figure then that of the non-hybrid motors?

[rmack]

I believe the EL and the AU Series 1 both have the same power.

157kW @ 4900 rpm.
357Nm @ 3000 rpm.

[ED_Boy]

dunno the exact colour but its like a ruby red, i think its called regency red or cardinal red im not sure ill get back to ya when i get the colour code

[ED_Boy]

cheers thanks for all the help, mine is a 97 motor so it probably isnt subject to the hybrid

[ED_Boy]

i know this is off the topic but does anybody know how much a set of pacemakers will set me back?

[ilsautomotive]

In future, please post your enquiry in only one thread. I have merged the 2 here. I'd suggest using the search facility for information on Pacemakers.

For interest's sake, whilst AU power figures were the same, I believe the torque curve was improved slightly.

they cost me about $350 from repco
i did a head exchange from veale coz the price but both veale n repco said no diff in the head between falcon fairmon fairlane or xr just whether its a late modle el coz of the au head situation - being that other bits dont bolt up properly

[Jason[98.EL]]

well i know i have a hybrid engine in my el

i had a good convo with the guys at "surecam" i dont normally name a company that are not a forum sponcor but this time i think i must

the person i spoke to told me that the el from 5/98 build had a full au engine

anything before that had a mix like rmackhas said in post #8

......(disclaimer)..... now i will not stand by this info as i only got it over the phone

now if this is right i need an au cam for my 6/98 el

if he is wrong wtf do i need an e-series cam def wont fit

Well, I got my cam. It was said that it would work for my hybrid motor, wrong cam, almost bent a valve.

As a result I am going EF head. Easier to change around heads than have my car off the road with damaged pistons / valves lol

You have to be very carful the people you talk to know exactly whats going on. Some can be easily confused on this issue lol

Cheers,

Ben

Well then mine must be a full AU motor then as well?
Mine was one of the last to roll off the line.

I think that 'tighe' do cams to suit the hybrid motors....Don't quote me on that though...

[Bipolar]

Is there an actual date from which the hybrids were produced to look for on the build plate?

[Dezza]

I think the ELs fitted with the "hybrid" engine also had a black painted engine bay, and had an unpainted rocker cover or something like that

hybrid motors are stamped on the head with 96DA.

[Jason[98.EL]]

mine has a painted engine bay

the rocker on mine is not painted though

jason

[335JET]

Heljas, what is your head stamped as.
should be 96DA.
