    New engine

    Hello all. This is my first post in the forum, most likely to be followed by many more. Well here is the story, I have a 1998 Catera that has a blown engine. 2 intake valves are broke and im suspecting that there is a big hole in the piston in that cylinder. So what im wondering is if you can get a 3.6 litre CTS engine to work in a catera? I have read that a 3.2 will work with little modification so i was curious if the larger of the two v6's would work too. Any help would be appreciated.

    Jon

    I would guess the your timing belt jumped. How much it advanced would really depend on whether or not you have piston damage. 1-2 degrees equals bent intake valves, 3 degrees you would have to remove heads for inspection, and 4-5 degrees is catastrophic at least one piston will have severe damage.

    To answer your question, no they don't swap (at least for the average person). The 3.0L and the 3.2L are from the same engine family (54* V6). The later engines that ran in the CTS are from a different genre of engine family. To actually get one of these in there you would need a whole lot of equipment, the donor car and it still may not work.

    I hear ya. Its catastrophic. 2 intake valves are broke and im pretty sure i the hunks of metal i found in the intake were from the piston. So a 3.2 will work? By that i mean the transmission bellhousing bolt pattern on the back of the block is identical to the 3.0 and its essentially a plug and play deal? If I went the 3.2 route would I need to get any computer tuning work done so it recognizes the new engine?

    Thanks again
