timdjohn Posted March 30, 2006 Report Share Posted March 30, 2006 In my 92 GP I have the stock 3.1 it runs fine for now but I know I will want more performance and plan for this winter project to swap out the 3.1 for another engine. I would like to start know to be on the look out for a good core but I have not decided on which engine to use. would it be easiest to swap in a 3.4 DOHC, or the 3800 Supercharged? i know the 3800 is much more performance but is it going to be a bigger hassle? I am just assuming that if I was to use the 3.4 I could use all my stock wiring and just maybe an ECM change, but I know with the 3800 I have to get a whole new wiring harness and computer too. In reality is the 3800 going to be more of a botherthen if I just settled on a 3.4? Thanks for any advice Quote Link to comment Share on other sites More sharing options...
jeremy Posted March 31, 2006 Report Share Posted March 31, 2006 I'd go turbo L36 ....but out of those two I would say go with the L67 Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted March 31, 2006 Report Share Posted March 31, 2006 3800 is much more work than putting in a 3.4. ( not to mention more money ) Id go 3.4 DOHC. Really it'll depend. Quote Link to comment Share on other sites More sharing options...
DaveFromColorado Posted March 31, 2006 Report Share Posted March 31, 2006 I'm a 3.4 DOHC fan all the way - but honestly, I'd say rebuild the 3.1 and turbocharge it. --Dave. Quote Link to comment Share on other sites More sharing options...
chadz34 Posted March 31, 2006 Report Share Posted March 31, 2006 I obviously vote LQ1! Quote Link to comment Share on other sites More sharing options...

I had briefly thought of turbo charging the 3.1 but to much of a hassle and I have never been a fan of tubo engine anyhow. I would fully rebuild whatever engine I was to use so I would rather get simalar power numbers with the 3.4 and no added heat wear etc of a turbo.

99RegalGS Posted March 31, 2006 Report Share Posted March 31, 2006 I second Jeremy with the L36, you can get a 1st gen Regal wiring harness. and it'll go right on the L36. Then just get the Regal 3800 mounts. and you're all set. Also, you can build a NA L36 to be faster than the LQ1. IIRC there's NA L36's running 13's.

Well then, I say go for the 3.4DOHC - you'll get the most N/A power outta one of those if it's built right. --Dave. Quote Link to comment Share on other sites More sharing options...

DaveFromColorado Posted April 1, 2006 Report Share Posted April 1, 2006 most of the 3.4 stuff is all custom, usually cam timing, internal mods (rods, pistons) and things of that nature. --Dave. Quote Link to comment Share on other sites More sharing options...
