Hey there everyone, I recently picked up a theft recovery Z and its missing the engine, along with dry sump , ecm, and wiring harness
Since I wanted to build the car anyway I want to know what Is needed for me to run a LQ9 engine in the 11z.

What bellhousing/clutch ?
Do i need a special Oil pan?
what ecu would I use?
Do i need special Mounts?
what king of wiring harness do i need ?

Any and all help would be greatly appreciated

ls1 tech is the best place for info. Not here lots of smart guys over there

you can get away with a stock vette pan harness and ecu

I dont have much insight on this but would love to see the details and a build thread if you go this route.

Ive lost one ls7 already and if it ever goes down again i'd be all for throwing a truck motor with a ton of boost in the car.

You probably want a gen4 block.

I have put the ls1 style blocks in the newer cars and it causes a few problems..

But the same covers and pans work on any and every style ls block.

Just pick any c6 specific piece and it will work fine.

The biggest issue you will have is the LS7 is a 58x reluctor wheel. The LQ9 is a 24x wheel. You will have to have a 58x wheel installed on the LQ9 crank in order to use the engine, among other things.

Also, you need to remember the Z06 engine sits lower in the cradle and further back than a regular C6. In order to make this work, you need the low profile LS7 pan which can ONLY be used as a dry sump setup. It does not have enough capacity to run wet sump.

Any other pan probably wont provide adequate clearance. See where I am going with this?

Engine sits in exactly the same place. Uses the same stands and mounts.

I have heard a few different opinions with regard to the Z06's engine cradle. If it is the same location as a regular C6, then a C6 pan should clear (I would think).

It sits in the exact same place and apart from the intake manifold it's tough to tell the difference - I'm running an LS7 in both my cars that were originally had LS2 blocks.

I have reg C6 2" kooks headers on my Z06 and they fit fine so the engine location is the exact same

The LQ9 is a great engine and with a few mods can produce LS7 power. The 2006-2007 LQ9 engines should have a 58x reluctor wheel, but if the Z06 ECU is missing, that leaves you wide open. Obviously, the easiest route is to replace the missing parts with Corvette parts, but the great thing about Chevy is many of the production parts will interchange.


Figure out what year your engine is, and proceed from there. If its 2005 or earlier, then find a Corvette parts donor in the same year category. Hopefully you can purchase the wiring harness, ECU, bell housing, clutch and motor mounts. It will also be helpful if the car is a manual transmission.
Good luck with your project.
