Default M90 L67 L32 or was it L36 - what????

Can someone help me with this jumble?

M90 is the Gen 3 blower - right? if so, what is the Gen 5?

L67 is the SSei engine -right? if so, what is the L32 or L36?

That'* a good start anyway.

Eaton M90 supercharger Gen 1,2,3,4,5......2 and 4 were rare but you can get a gen 4 from magneson.
L67 is M90 gen 3 (97 on anyways)
L32 is M90 gen 5

Let'* muddy this up a little more....

87-91 NA (only choice) were LN3
92-94 NA were called Series 1 and L27
95-?? NA were called Series 2 and L36

92-93 SC were called Series 1 and L67 (M62 blower w/o epoxy coated rotors)
94-95 SC were called Series 1 and L67 (M62 blower with epoxy coated rotors)
96-03 SC were called Series 2 and L67 (M90 blower, coated rotors)

One correction. 88-91 were LN3. 87 only was LG3. And one more nit-picky thing, the rotors were TEFLON coated, not epoxy coated. Epoxy wouldn't work to well

and for more confusion EVEN more

Some 92 L27'* were EGRless with a aluminum upper intake
93 L27'* Have a revised valvetrain over the 92 models with the EGR

92-93 Had the Gen 1 SC w/o Epoxy
94-95 had the Gen 3 (i think) w/Epoxy
96+ you cound get the Gen 1-4 SC in the Bonne (Most cars have the 1 or the 3)
