The supercharged series 1 3800 in the Bonnevilles and Park Avenues have a stronger bottom end than the L27's do. Stronger rods and pistons. It is a LOT easier and cheaper to drop an already supercharged Series 1 in your car than it is to supercharge your L27. Trust me I've looked into this a lot. People have tried and there's way too much work to be done. If you have to pull the engine to swap pistons and rods, might as well swap the whole engine.

digitaloutsider Posted February 9, 2010 Report Share Posted February 9, 2010 I imagine that you could probably bolt the Series I L67 heads onto the L27, but then you're talking about swapping the crank pully, associated pulleys, fuel pump, doing custom wiring. It's far from worth it. The Series I L67 blows anyhow. Quote Link to comment Share on other sites More sharing options...

It's far from worth it. The Series I L67 blows anyhow. The heads are identical between the 93+ L27 and the Series 1 L67 (and both flow like shit; less than the Series 2 L67, which flows even less than a 3x00 engine). Its the rods and pistons that won't like the boost.

digitaloutsider Posted February 9, 2010 Report Share Posted February 9, 2010 Poor fuel economy, poor performance, yawn-inspiring powerband. But hey, it was the first of it's kind. Unfortunately like the L27 and all early 3800s out there, there are much more cost effective powerplants to pick from and I don't see the point in even dicking with an SI L67.

digitaloutsider Posted February 9, 2010 Report Share Posted February 9, 2010 Maybe, but the L67 was already well into development. I wouldn't be surprised if there are a few L67-powered early first gens hiding in a GM warehouse somewhere. Quote Link to comment Share on other sites More sharing options...
WhatTheFehl Posted February 9, 2010 Report Share Posted February 9, 2010 I would love a supercharged 3800 in my car, a series II though. I can't say I'd lose anything. I'm inexplicably getting the mileage of a V8 right now anyway. Quote Link to comment Share on other sites More sharing options...
WhatTheFehl Posted February 9, 2010 Report Share Posted February 9, 2010 The 3800 was in my opinion pretty much the best engine GM ever created. I've never understood why the only first gen W it was offered in was the Regal. I think that would have made a better platform than the 3.4 Quote Link to comment Share on other sites More sharing options...

Certainly not from a performance standpoint, but from an ease of maintenance and repair, reliability, and fuel economy standpoint, it ranks pretty high up there. Even as far as performance goes, it's not a slug. Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted February 9, 2010 Report Share Posted February 9, 2010 I think the LQ1 was an excellent choice for the GTPs, Z34s, Int'ls, etc. High-revving, powerful DOHC motors were in, relatively unrefined clunky pushrods were out. This is not to start a flame war (and it better not, or it will result in vacations), but the 3800 was just better suited for a Buick. It was sort of torquey, simple and easy to fix so it appealed to the demographic. Quote Link to comment Share on other sites More sharing options...
WhatTheFehl Posted February 9, 2010 Report Share Posted February 9, 2010 A powerful yet overly complicated, high maintenance engine doesn't appeal to me at all. I'll stick to the 3100 until I can get a supercharged 3800 Series II put in. I have no desire for an LQ1. No offense to anyone here who loves them... in my opinion, they aren't worth the trouble.

xtremerevolution Posted February 10, 2010 Report Share Posted February 10, 2010 I personally wouldn't think twice about picking up a low mileage Series 1 L67 to drop in the regal if one with the right price popped up. It would be a direct replacement to my engine, and swapping over the roller rockers I have would bring it up to if not over the performance level of a stock Series 2 L67. Granted, I have no idea what kind of fuel economy to expect, but that's a different story. For the time they were released, they put down decent numbers. 225hp/260tq on the series 1 vs 240hp/280tq on the series 2. Its not really that big of a difference.
