View Full Version : 2006 STS Makeover

01-08-12, 08:38 PM
Trying to fit a 3.6L 2007 - 2011 sts engine into a 2006 STS 3.6L. Is this possible? And is there a mechanic in the south florida area that can do this type of conversion. Also, would like to replace tranny with a 6 speed trans.

honestly for what reason?

Economics, the cost to replace the timing belt would be just about the same $$ as replacing with a used engine.

don't both engines utilize a timing chain?

It sounds like misplaced economics. You'll spend twice what you think.

All thanks for all your help!!!....my cadillac service advisor did some research and found the only engines to fit my 06 sts would be 05 -07. After 2007 the engines change to direct injection and there are no aftermarket coupling wiring harness for the electrical system.
