Bonneville SSEi

Does anyone know if the supercharged engine was placed in a H body model Bonneville (87-91)?

Trick question???     Bonneville is a B body.  H body is the 70's  Sunbird, Monza ect.  I believe the Buick 3.8 V-6 would have been the engine, but don't believe the SSI came out til the late 90's.  We were building the Bonneville at the Orion plant when the SSI came out.

I’m new to this but I understood the G body was the last of the rear wheel drivers up to 76, then the front wheel driver was labeled the H body (the really squared off model) and ran 87 - 91.  Or so I thought…

Sorry…G body up through 86…

Actually Jack is correct. GM re-used the H-body designation once the RWD G-body went out of production. So while the H-body did encompass the Vega/Astre/Sunbird/Monza platform initially, it was later re-used for the full size FWD platforms starting in 1987,

GM did NOT offer the supercharged Series I 3800 in 87-91 edition Bonneville. The LN7 engine was only available in Buick Park Avenue Ultra from 91-95.

1992–1995 it was available in the:

Oldsmobile Eighty-Eight LS (optional), LSS (optional)
Oldsmobile Ninety-Eight Regency Elite (optional), Touring Sedan
Pontiac Bonneville SE with H4U RPO, not badged - SLE (optional SC package), SSE (optional), and SSEi

In 1995 Only:

Buick Riviera (optional engine)

The Series II 3800 was introduced in 1995. The L67 was the supercharged version of Series II engine.

Would have bet $$$ GM didn't use the H body platform again.  Knew they switched the Bonneville to G when they classed it as mid-size.
