If i were to fit a GM LS series V8 into my miggy, would the ECU Black Box(es) fit within the engine bay without modification?
If modifications are required, can anyone tell me what they would be?

[Shane mvsex]

im very interested in this myself, i would love to fit a v8 in my mig...
maybe one day but i will keep watching 

[Lesopc]

Just a little something i think should have happened. GM/Opel/Vauxhall did originally plan one but it never materialized.
Mine would be a Irmscher Team V8Star tribute car from years 2001-2003 driven by the great Jonnie Cecotto as car #9 and #1 (2001/2) and Yves Olivier (2003 R1&2) and Roland Asch (2003 R3,4,6&7) as car #2

I'm afraid I'm not able to help on the technical side, but perhaps this official photo of the planned V8 Omega may help? I think I have a few more, I'll try and dig them out.

Much of the mechanical details are within TIS, but no wiring info.  Also, AFAIK, the different code indexes and configurations for the associated ECUs (gearbox/ABS) never made it to TIS, thus not available.

I'll have to get the pc out, Tis only gives me wiring diags for some reason?  :-/

Youshould have the room in the engine bay because they used the same chassis for the Holden Commodore of the same year and they can with a V8. Father-in-law has just sold his HSV GTS VT-II, such a lovely car and the main reason i bought a Mig

[Lesopc]

So in theory it should all fit then?
Thanks guys.

Awaits a post from 2woody...

When the v8.com Omega was originally conceived (before obviously being canned) - was it the LS1 or LS2 engine that was fitted?  (I can't see it have being the Northstar V8 they envisaged fitting to it)  :-/

[feeutfo]

North star is way too wide. We know the steering box was retained, there are pics on the web of additional cooling rad and plumbing for the pas system, and we know an LS1 has been fitted diy, which is very close to the steering box meaning special headers had to be made to clear the steering box by the rear cylinder on that side.
 Ls engines are twin valve per cylinder with push rods working off a single cam in the valley of the v, so there are no cams in the heads, only rockers, this makes the Ls heads very compact and narrow.

 North star is double overhead cam four valves per cylinder. So that naturally makes both heads wider, and hence will not clear the steering box. Will n star fit with a rack? Maybe, but note the v platform was widened for use in Holdens etc. The Holden is a  wider car I am certain.

Also I believe the Northstar was originally designed for front wheel drive applications.

V8 and FWD. That sounds like a whole lot of fun an expensive tyre choice...

Yes, seems odd to me, but each to thier own as they say...

Afaik, by far the biggest problem fitting an LS1 will be the exhaust manifold/steering box collision issue on the rear cylinders, then getting the exhaust to exit down the transmission tunnel, there's very little room.

Here's an LS1 in place, see the position of the steering box, where the rear exhaust msnifold should be exiting.


And here is the original exhaust manifold designed for the v8 omega on the steering box side, left hand drive in this case, note the shape of the rear exhaust exit from the head due to the space available.

[feeutfo]

So siting the ecu will be a minor issue. But having said all the above this conversion has been done, by at least two people on both sides of the pond.
