Series 1 and series 2 engines completely different..?
Ive only been researching these motors and years for a couple of days. Ive been emailing back and fourth to zzperformance he told me of the m62 blower on the series one and the m90 blower on the series 2 but now ive been told the the engines are completely different..? I thought all the 3.8 where the same. Could someone set me straight? Thanks Tug

The series 1 is a slightly different engne than the Series 2 or 3. Mainly its slightly different parts, as well as blowers. The change is enough however to get to 205 HP on the series 2 bonnies, (from 170 series 1).

The big differences between series 1 and 2 simplified:
Series 1 Series 2
4t60e tranny 4t65e tranny
M62 blower M90 blower
OBD1 OBD2
There are even differeces in the parts within series 1 engines as well. Stuff like 92 was EGRless and 92/93 had a different SC pulley and TB than the 94/95 did. I believe stuff like series 2 headers, vavle components, pulley systems, all will not work on series 1 due to design differences. Also within models inthe same years I have been told there are slight differences. Stuff like how headers will fit around the engine due to the different designs of the car.
There is a fair amount different from series 1 to series 2 but most things are small changes made between the two.

For the supercharged L67:
92/93 205 hp, tons of torque
94/95 225 hp, tons of torque
96-03 240 hp, tons of torque
Series III (if the bonneville ever sees it) 260 horse.

Ah, the all so popular couple issue.
The coupler sounds like it needs to be replaced. If you do some searching on the forum (and might be in tech info too? just to lazy to look myself) there should be a few threads here with all the info you need. It is a $20 part that needs replaceing, not the whole sc.
