Outer Limits 4x4 Board

How much are one of these babies worth?

Ive been offered a 93 EFI Disco motor, complete with loom and computer and all accessories which has been fully rebuilt with a 4.6 cam for $500.

All that it needs to get it running well is the Air Flow meter.

This would be to replace the carbed 3.5 in the stage 1

So any ideas?

Would it be worth looking into megasquirt for injection?

Dave.

Saab 900s AFM should be the same from 1993 onwards IIRC. They should be $160 ish last time I checked.

From rover an AFM would be $400 ish. The 3.9 AFM is a 3AM (from a rangie) and 5AM from later models and discos.

Nice. Thanks for the tip tom.

What whould have to be done to the fuel system to set it up for EFi?
Surge tank? Inline EFI fuel pump?

Are there any other majors items that i would need?

Dave

dont buy it let me get it I would Megasquirt it too

Toms on the money. And you "may" need a surge tank. I would run a Commodore external EFI pump. You will also need a return line but maybe the small Carbed one might be large enough.

If you decide not to but this we would defianatly be interested in this at Haultech. Always chassing 3.9EFI motors for our buggies.

Thanks Ruff, i think it may be a 3.5 though. I would love a 3.9 though!

1990-1993 3.5efi
1994-1999 3.9efi
So I think its a 3.5 didnt relise that at first.

I would still megasquirt it


EDIT: I could be wrong cause 11/93 model discoveries have a 3.9efi

Dave, if you use a megasquirt you don't need the airflow meter. This is reason enough to do the conversion IMO.

Hopefully i will be fitting my megasquirt over the next little while so i will have an AFM for you if you're in no rush.

Sounds good, i might go bump / read that thread again.

Have you got all the components yet?

Dave.

I have got the MS built (big thanks to Mickrangie ).

I still need to get sensors and wire it up though. At the rate things are progressing on the RR at the moment it could be quite a while before all this happens. I have to get the manifold spacers machined for the 4.4 because they are not even close to being right .

I'm running out of things to do on the Disco so perhaps the Rangie will be ready for winter in 2008.

This wont be hurried either. All depends when this ute is ready for the conversion. I also need spare $$$ to do it.

Once you start, give us a pm and i'll have to come around to see how it all works.

hey

my mechanic just told me my air flow could be the prob for what is wrong with my disco its a 93 disco.

he said if it is that it would cost me $800 to fix is that right ?

if you know of any cheaper i will buy it
also is there another way around it

Tom

So look inta a SAAB one.

Dave

On a side note -

I started investigating sensors for Megasquirt.

A VR MAP Sensor
Part NO - 9m107n
$110

&

VL AFM
Part NO - 4am008n
$260

All prices from Repco, new parts.

Could you retro fit to the existing Lucas EFI a VL Commodore AFM?

Dave.

EDIT: I could be wrong cause 11/93 model discoveries have a 3.9efi

My 10/93 is a 3.9 as well.
