eng bay doimensions - XF eng bay AU eng

[ISL33P]

Hi All,

as you can tell from my signatures i fabricate inlet manifolds and i am in the process of designing one for a 250 from a AU to fit into a XF.

Can you please help me out with some dimensions as the customer doesn't have the engine in the car.

I need the distance from the cylider head - please specify cylinder no - directly perpendicular to the strut tower. Any engine as i would think it would matter which specific engine it is aling as its a 250 xflow, they are all around the same size. Also if anyone has the distance from the front of the head to the power steering pulley and from that line (drawing a right angle) to the outer edge of the ps reservoir (AU eng), it would be much appreciated.

Thanks again all for you help and congrats on one of the best presented forums I have seen.

Regards,
Ariel

Mate, have done a BBM to 250 motor.... how many you want ?.

[ISL33P]

do you mean how many measurements ?

[Muzza]

How many manifolds do you want ?

[ISL33P]

none for the time being

hes trying to get measurements guys not asking if he wants manifolds etc

if i had my car here champ id take measurements for ya

This is the ones I made. This was on an XE (which died suddenly) and is based on an EF BBM.. which is same as EL and AU should be the same as well.

The issue is not clearance to the shock tower or powersteering but the space been the dizzy and the bonnet.

All I had to do was "replace" the flange section with the XE fuel rail section.
No need to shorten or change any angles as it needs to fit between the bonnet and the dizzy... more on that later.
It all works out well with good clearance to the shock tower and elsewhere.
Basically, slice off the flange section just after the injector ports and fit in the same width XE section, keep the orientation of the whole manifold the same (just remember that the E series head ports are vertical and the 250 ones are on a slight angle... make allowance for that).

Once the two sections are welded together port out the XE part to match the diameter of the EL section tapered through to end up with a better port match to the head.
I made new mounting sections for the fuel rail.

The only hard part was the vacuum connection. Because the XE regulator is close to the EL vacuum connection I made a special one (can't see it in the pic) which allowed the original vacuum tree to screw in and it ends up in about the same place as original....can provide more pics of that if it helps.

There are two issues you need to consider:-
1. You will need to use a Eseries dizzy as the original X series one is too tall to fit inder the manifold.
2. The very front "loop" section of the BBM will come very close to the bonnet and you will neet to modify (trim) one of the reinforcement struts under the bonnet.
Otherwise clearance is fine all round with about 15m to the shock tower and no issues to powersteering.

There is minor stuff like dipstick but easily addressed.

BTW, I also make a BBM switching unt module (based on RPM).

Hope that helps.... drop me a line if you need more info or pics.

sorry, i only just noticed this thread, theres a shit pile of room, but the biggest issue is the power steer pump, i using a remote resoivour style pump, and locating it on the drivers side, so no issues for me
i measured mine, it roughly comes to 230mm from head to edge of plenum at the strut tower, leaving me with about 1" of clearence
this is as long as i could go with the runners with my plenum dimensions

he's fabricating a plenum though, differnt kettle of fish again

Sorry, since a 250 motor and AU was mentioned I assumed it was a AU BBM that was being fitted to a 250 motor.
If it is a BBM this is how it looks fitted....

oh, and also watch out for the heater hose pipes out of the firewall if your using straight runners
