A brand new year and hope fully will be productive one. 2025 was the year of
big money on the engine and mounts. This year though not as expensive
still will need big investment into adapter and electronics to get the
engine running and hopefully have the car drivable and all the other
hundreds of things that need to be finalized.

Had been looking at engine wiring for last couple of weeks. The
harness poses couple issues, firstly the fuse box and ECM connectors are
at front of the engine in the donor making it very tight to locate both
the fuse box and ECM. Might be able to make indentation and recess them
into the wall but regardless it will be very tight. Ideally it
would be best to have engine rewired with the ECM and fuse box located
somewhere behind around transmission area. Then again would like to stay
away from that as might put turbos and will need to keep the ECM and
fuse box from any heat source which again leaving them in front of the
engine on firewall or just about. Secondly the way GM designed starter
and entire security around the electronics is around BCM in place
to controll the ECm and fuse box. There are ways around it will
involve rewiring both the fuse box and ECM slightly.
Looking and sudo solution and make an BCM emulator to trigger power
relay in the fuse box and ECM. One thing for sure is that VATS
will needs to be deleted and ECM in general reprogrammed for the purpose

With winter at its peak, garage is cold and not very inviting to work
in. However went out to have bit of a sanity check on mounting and
overall clearances of the engine.
So as it looks engine lid sits way above of what was expected and
observed when working with LS1 from 02 Camaro. However with the LS3 is
rather taller and what it looks like is contributed mainly from the
intake and possibly from the taller oil pan. will have to look into
Corvette intake plenum to see how much lower it is. Its possible to
replace oil pan and dropping entire setup downwards bt not sure how much
of a benefit that would be as most likely axels would be hitting lower
frame rails and CV joints would not be at optimum angle. As it sits with
the OE camaro mounts and isolators, oil pan has 18mm clearance to bottom
of frame and as the car will be at about 12cm ride height would like to
avoid any possibility in having it damaged.
On a good side with the way the engine sits, it has enough space to fit
oil cooler for the engine and possibly transaxle. Also it has space for
cross fit of coolant hoses and shifter cables.

Spent few hours with CAD and drew up drawing of adapter plate after
searching for few more hours before hand (not counted) for proper
dimensional drawing of the GM SBC / LS transmission face mounting
surface and Audi G86 transaxle mounting face. Biggest issue is with the
2 lower bolts on the LS face with in the oil pan.
Sent out couple quote requests to have the plate machined. Hopefully it
will be much less then getting it from 3rd party manufacturers.
