I thought the UK monaro had an LS3 in it?
My Indecisive 4.0 V8 1UZ-FE Project - FirebirdPhil - 17-12-2019
It had both IIRC.

Twin engines? Awesome!
My Indecisive 4.0 V8 1UZ-FE Project - el_bandido - 17-12-2019
or a spare in the boot?

I'm not an expert on them but AFAIK the early ones were LS1 5.7 later ones were LS2 6.0
Mine's had a few bits done and is making 380bhp but my 330bhp RX7 is faster (450kg lighter)
My Indecisive 4.0 V8 1UZ-FE Project - FirebirdPhil - 17-12-2019
RX7's don't weigh anything so its no surprise.

toxo Yes the steering rack is an issue, even with the soarer sump it's the lowest point of interference. As you're aware dropping the rack introduces alignment issues but is very common among the LS crowd.
If I get to my workshop this weekend I will post photos of the soarer sump setup positioned in the engine bay.
As promised...

As you can see the steering rack is still the first point of interference. Although the upper sump doesn't have the oil pan attached to it yet you can clearly see that it wouldn't affect the height.
Despite that, it is shaped like it was made for it isn't it?

Took the LS400 oil pan and sump off the VVTi engine last night:
Engine rotated through 90 degrees for access - turns out the oil filter wasn't empty!

Oil pan off:

Close up. As you can see the oil pickup is a very different design to the Soarer one, presumably to reduce surge or oil foaming:

Upper sump off:

The rods don't actually look that thin. Certainly not as thin as some that I've seen photos of. Will have to look into that. Other good news is that the mounting holes for the Soarer oil pickup location are already drilled and tapped!
My Indecisive 4.0 V8 1UZ-FE Project - toxo - 20-12-2019
So then we did a test fit on the Soarer upper sump. I was aware that some of the holes would need enlarging, but not which ones or how many, so this was the only way to find out!
Soarer upper sump test fitted:
![[Image: IMGP3341-e1328037659335.jpg]](http://www.project-ruze.co.uk/wp-content/uploads/2012/01/IMGP3341-e1328037659335.jpg)
Unsurprisingly it fits straight on. I didn't bother with the oil pickup etc as it's not staying on there long.
This is what we found out after a bit of mucking about (you might have to click to open it up big to see the highlighted bits):
![[Image: IMGP3341-bolt-layout-e1328037507596.jpg]](http://www.project-ruze.co.uk/wp-content/uploads/2012/01/IMGP3341-bolt-layout-e1328037507596.jpg)
Key:
GREEN: Reuse bolt from Soarer engine (M6x1, 20mm long, 10mm head)
PURPLE: Use either bolts from Soarer engine or VVTi engine, they are the same (4 M8x1.25, 80mm long, 12mm head and 2 M6x1, 20mm long, 10mm head)
BLACK: Hole in Soarer upper sump needs enlarging from 8mm to 10mm. New bolt required, M8x1.25, 20mm long
RED: No modifications required, just needs a new bolt, M8x1.25, 20mm long
YELLOW: Hole in Soarer upper sump needs enlarging from 8mm to 10mm. New bolt required, M8x1.25, length as yet unknown but likely 100mm
So now I need to find somewhere who can enlarge these holes for me. I'm happy doing the ones in the thinner parts of the sump myself, but the 2 in yellow are through an 80mm thick bit of metal and there's a bit too much scope for veering off to one side. I don't have a pillar drill but I think there's one at work I might be able to grab the use of briefly. Once the sump modifications are done, I will need 8 new 20mm M8 bolts, and 2 new (likely) 100mm M8 bolts.
I'm not totally sure about the holes marked in yellow. On the Soarer these were long thin studs. I can't reuse the Soarer studs because they're too thin to fit the thread in the VVTi block. However the oil pan bolts directly on to them so if I replace them with a larger bolt that has to fit inside the lip of the oil pan, and the holes on the pan will need enlarging too. More thought required there.

I don't know if you're using 100MB pics or something but its taken 10 minutes and 3 attempts to read your last 2 posts.
