Hey guys, i have a 95 buick lesabre 3.8l n/a and i want to put a 3.8 series 2 supercharged engine into it. I know it is possible but i dont know what i need
i know i need the engine and transmission anything else?

This is assuming you have an L36 since IIRC Buick still used the L27 in a couple cars in 1995.

You can drop in an L67 with your original transmission and a tune from gmtuners.com.

You'll need to use your stock flywheel so the stock torque converter bolts up, stock coolant temp sensor, stock knock sensors or splice the new ones in, and that'* pretty much it.
