CruxGNZ Posted November 22, 2003 Share Posted November 22, 2003 You need the complete running gear from a Turbo Regal or a Grand National, preferebly from 1987. Engine, transmission (if you want to stay with the 2004R), wiring harness, computer, ect. Making engine mounts and tranny mounts is up to you. I've got a '73 also and you will need to upgrade the rear end to be able to live with the torque from this engine. These engines like to be loaded, so the higher the rear ratio the better. There are also options for the wiring harness, computer, and transmission. Have you researched this at all? I don't want to scare you off, just want you to be informed. It's a fun, but fussy engine. Definitely a unique swap. There has been quite a few different vehicles that the LC2 has been swapped into. Go here to get some ideas and to read up a bit: http://www.turbobuicks.com/ubb/ultimatebb.php?ubb=forum;f=3 and http://www.gnttype.org/ !M!

Guest elephantman240 Posted November 22, 2003 Share Posted November 22, 2003 thanks for the info, what about the driveshaft and what rear end would be a good choice Quote Link to comment Share on other sites More sharing options...
CruxGNZ Posted November 23, 2003 Share Posted November 23, 2003 Custom driveshaft is needed. For a rear end, this is up to you. If you want to keep the cost down, then get a R200. You can also swap in a R230. You could also go to a solid rear, but this all depends on what you are going to do with your car (drag strip, street car, road race, ect.) For information about any of these options, goto the "Drivetrain" forum and search. There is a TON on information in there. !M! Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted November 23, 2003 Share Posted November 23, 2003 E-man240, spend a little time doing searches on this site as there is probably more info than you can digest in one sitting. Next visit that turbobuicks URL Mat recommended. You will need about a month to digest all the detailed info about various LC2 swaps . If you still decide to do one, all of us with GN-powered swaps will help you through it. Quote Link to comment Share on other sites More sharing options...
