I really can't wiggle anything under there Neil..
I still don't see how lifting and wiggling the transmission/bell housing can help..
The clearance when I tilt the front of the sump down and the rear up gets even worse.. I can see that if I lift it up heaps it will come out, but thats a long way up..
And i'd be my luck if I wiggle the whole bloody car will fall on me... |

Just yank really hard, I think that's what I had to do...

Yeah, give it a good yank - the metal will flex a bit and it should come out. |

SUCCESS!!! 
I ground off the offending material with my brand new $39 angle grinder!!!
Hokay, so, first of all.... These rods look pretty thin to me.. I had a suspicion that they would be due to the ECU being different..
Could someone in the know confirm?
Now... All I need to do is work out where to put this oil return..
I was thinking either here with a barb and some sealant above the oil line.. like KC's
Or here..
On the actual sump below the oil line with a speed flow connector welded in somehow and still able to fit the oil pan back on.. (threaded maybe) |

Is there a measurement I can take to find out which rods I have?

Looks like the thinner rod to me

I checked that picture before posting, and I'm still not sure...
It may be the angle playing tricks...
If you have a look at where the rod connects to the gudgeon pin it doesn't look like the thin one..

Is there a way I can check from a build number or something? |

Toyota seem to think it's fine for a sump..
I'll most likely be going with the sump option with speed flow connectors. Just gotta be sure I can get it in and out with the fitting in place.

Tai,
When I had my oil pan off, I thought my rods looked pretty thin as well. I was assured by a few different people that they were the thicker ones. I've seen as much as 12psi with one of my non intercooled setups and (knock on wood, no pun intended) nothing has broke yet.
I don't see any problems with black sealer...just make sure its not blocking the path for oil to drain. I've never had a 1uz apart but on a 4 or 6 cyl Toyota motor, sealer is used for just about everything. Timing chain covers, oil pumps, the oil pan, the upper sub pan, ect.
Just to be sure, you do know that in the steel pan, your fitting will most likely be below the oil line? Just want to make sure you're aware. I don't know how much oil the engine uses when it is running, but I wouldn't think it would be enough to go below a fitting in the pan.
Good luck!

Well it's definitely a 94 model..
So if what everyone says is true, they are the early rods..  |

Yep, I understand...
I have thought long and hard about placement.. I will be welding in a thread and using high quality speed flow connectors. It will only be under the oil line by a few centimeters at rest.
The sump plug is a simple thread and bolt, and it hasn't leaked in the last 2 years
If anything goes wrong there will still be oil in the pan, and my oil level sensor should let me know if it goes real bad  |

I thought the return had to be above the oil line as it might impede return flow otherwise?
Impeded return flow can cause lack of lubrication and bearing damage.
I guess when the motor is running the return will probably be exposed.

I'm not sure how much the oil line will drop once the motor is running but I don't think it will matter..
I have heard people say this a lot, but I think it might be just a wives tale.
I don't see how the flow is 'impeded' simply because the level is below the oil line.. The oil can only come out as fast as gravity can pull it.
In my mind the oil level would have to rise above the red line before I considered it to be impeded.
From what I understand on returns, the oil quantity and flow is quite small.. The feed is a flow restricted -6 line, the return is a free flowing -8 line. I don't see there being a build up.
I have heard that the oil from turbos is whipped and very aerated, this could possibly escape easier from the above sump return..?
All I have done is think about it though. I have no real experience.. I think it's an interesting discussion and I'd like to hear what other people think. |

I would be making the supply from alot lower than LINE A... When driving round corners and chicanes and hard breaking, the last thing you want is oil starvation to the blower bearings... Supply is parramount. |

A and B are alternate return line options, not supply |

From the Vortech website...
Can I use the existing drain on the oil pan to return the oil from the Vortech supercharger?
No. It is imperative that the oil return be higher than the level of the oil in all instances. The oil must be drained gradually downward with no dips, allowing the oil to enter the oil pan above the oil level. Drain restrictions, kinks or returning the oil below the oil level may cause a severe windage problem that consumes significant power and generates heat, supercharger seal failures may also result.
Looks like I might have to go with the above sump option... |

The more i look at these damn rods, the more I convince myself that they are the weaker ones 
Could late 94 have been the change over point?
Does anyone have a measurement that I can use to compare?

Ok, I don't know if this will help, but....
I have access to TIS (Toyota Information System). On TIS, I can look up new model info. There is some very interesting stuff in the new model documents. Well, for an SC400, new "improved" light weight rods and a change from 10 to 1 to 10.5 to 1 CR is listed in the 96 new model document. This implies everything under 96 (mine is a 95 BTW) has the early rods. The rod change seems to coincide with the change in engine management, from OBD1 to OBD2. LS400's list the change in the 95 new model documents.
I'm not sure how this would all apply to a Soarer, but I feel good about my rods.
I work tomorrow, if you would like, I can look up some info on the rods under the rebuild sections. Surely there is some info on measuring key points of the rods. If so, I'll compare the measurements listed between years to see what the difference is and post the info.

Taken from the engine mechanical service specifications page, rod thickness is...
22.880 - 22.920 mm or .9008 - .9024 inches.
This is for 92-95 SC400 / LS400. I cannot find the same info for anything over a 95. Not sure why.
Also, says rod thickness but doesn't specify where to measure. Hope this helps some.

Thanks mate, that definitely helps.. Even if it's a ballpark figure, it's something to compare against.
I'll see if I can squeeze some vernier calipers in there  |

Pretty sure that will either be the big end or little end thickness, which I believe is the same for all UZ motors. |

Some trial fit pictures....
There are still a few things that need to be moved, but it's good to see a hint of the future...
The mounting bracket is very solidly mounted and so far the fit has been very precise. |

Oh yeah, what fluid is used in the engine fan system.. I have to top it up a bit due to re-routing a hose...
I have washed my hands like 3 times and they still stink  |

Oil return pictures... The braided line will be held away from the exhaust..
I used a 90 degree chuck to drill the upper sump.. It was a pain and i'm glad it's finished
Another picture of a rod too.. I'm pretty sure they are the weaker ones.
