SuperBuick Posted October 1, 2002 Report Share Posted October 1, 2002 ooooooooh paaaaaaaahwaaaaaah. hehe I have a series 1 3.8 in my regal. It should be ver simple, all you will need it is the motor and the computer. all the other stuff should bolt right on aka alternator, PS, tranny, radiator, yaddah yaddah yaddah.

93 Grand Prix Posted October 1, 2002 Report Share Posted October 1, 2002 Why don't you go ahead and go for the Series II 3.8? It is not that much bigger is it? Quote Link to comment Share on other sites More sharing options...
SuperBuick Posted October 1, 2002 Report Share Posted October 1, 2002 Same size, 30 more HP and about the same torque,. The guy down at the local buick shop told me the series 1 has way more potential though, and he wants to do a custom turbo setup on mine, which will take place next year. Also, the series IIs have manifold problems (they leak coolant into the motor). In addition, they are butt-ass ugly engines. Quote Link to comment Share on other sites More sharing options...

SuperBuick Posted October 1, 2002 Report Share Posted October 1, 2002 Unless its one of the earlier non-teflon bladed superchargers (205hp 265 tq), a supercharged s1 puts out 225 horses and 280 lb/ft torque - damned good if you ask me. i'd certainly love to have one, but bonnies and rivs are too much $$ to just buy to rip the engine out of. - Tom Quote Link to comment Share on other sites More sharing options...
