svt4cobra6 Posted July 11, 2014 Report Share Posted July 11, 2014 Hi everyone. I have a 1998 lumina. It's been in the family since it was new. My wife got it from her mom while I was deployed. Honestly, when I first started driving it I hated it. It since has grown on me. It's just too slow. I pulled the 3100 about 6 months ago and rebuilt it. I wish I would have upgraded. I'm looking to upgrade now though. Quote Link to comment Share on other sites More sharing options...
Heartbeat1991 Posted July 11, 2014 Report Share Posted July 11, 2014 Boost it!! Quote Link to comment Share on other sites More sharing options...
svt4cobra6 Posted July 11, 2014 Author Report Share Posted July 11, 2014 The stock 3100? It doesn't seem that strong. That last one cracked the block and spun a rod bearing. Maybe it was just back luck though. Quote Link to comment Share on other sites More sharing options...

Nas Escobar Posted July 11, 2014 Report Share Posted July 11, 2014 You can upgrade to a 3800 or a 3500. It's your pick. The 3800 is the famous Buick engine and the 3500 replaced both the 3100 and 3400. The 3500 would be more of a direct swap than the 3800 using your current wiring and PCM but a donor Lumina LTZ or Z34 Monte Carlo would make the 3800 a plug and play thing if it's not Supercharged. Supercharged 3800s will take more work. Quote Link to comment Share on other sites More sharing options...
