ls 6.0 lq4 motor in caddy....
« on: November 24, 2015, 06:21:54 PM »
First of all Hi to everyone, been a while since I have been on....

Who has done the converstion?
I know everyone is gonna hate me for doing it but I need the reliability and the performance of a Fuel injection.
I just bought a 2002 6.0 out of a gmc truck, and need to figuire out what is first.

I am going to send out the ecm and harness to get modified to work as a stand alone unit.
Then motor and tranny mounts.

Hi, dbranco. Im currently in the process of doing a conversion as well. What questions do you have? As far as motor mounts, I found a gentleman with a completed conversion that used BMW m3 mounts. They bolt directly to your frame, and only need to add a tab to the flat plate mount on the engine. The crossmember will need to be notched to clear the oil pan, and the pwr steering pump. I have opted to use a alt/pwr steering pump bracket that raises them in order to avoid notching so much.

None of the above pics are mine unfortunately. Almost everyone has an issue with the driver manifold hitting the pwr steering box, and headers are easier to manipulate then cast iron ;)

Motor finally out and SOLD and tranny too.

Hopefully next weekend we will try and dry fit motor in and see what the hech needs to be cut and moved out of the way.  Plan on cutting front crossmember, just dont know how much.
Also thinking might need new steering pump. 

Just to start off with.  Big job but worth at the end.

Would love to see a full build thread on this swap. I've considered one of these swaps myself as my engine is questionable at best.

Before you cut the cross member i would do a search for a different oil pan. LS engines have been installed in everything already....tons of companies making custom oil pans for them. there's got to be at least one that works....take a look
