I was wondering is it possible to put the Supercharged 3800 Series III V6 on a 1999 Bonneville SE or SSEi is it too big to fit or the mounting brackets are different...just wondering

its possible, however you will need at the bare minimum:

Engine
Transaxle
Wiring Harness
PCM



Plus the other stuff that is beefed up on the L32 cars.

If you start with an SSEi, you might get away with the original tranny.

isnt it the exact same tranny? internally speaking? other than the 3.29'* that come in a comp G.

yes the wiring is different


ontop of what was already mentioned you need to deal with the TB


Here is a suggestion though....

If you start with an SSEi, a GEN V SC on the L67 will give you a power increase, that will get you close to the L32

ya i for got to mention that. and you would have to figure out a was to run the tapshift, unless u didnt want it.

L67Swap.com is your best bet to get info since no one is speaking from personal exp.

Have they dealt with the S3 'fly by wire' yet?

i dont believe so.

Yes, Fast Fiero is a SN on the forum. He name is Loyde and his website is fastfieros.com ... I know him because Ryan'* uncle has sold him a few items for LS1 swaps in w-bodys. I know that Loyde has dealt with the fly by wire and the tap shift in a fiero swap personally.

Even if Fast Fiero wasn't on their I think that the people on L67swap would have a better understanding of what it takes to do a swap like that.

I do know their is really no reason to do a L32 swap over a L67 swap other then the Gen V M90.
