1984 Oldsmobile Cutlass Supreme Brougham

[g0thiac]

My father's Oldsmobile, a 4-door Cutlass with an anemic 231 2BBL V6. That engine used to make 110 hp when it was new, but now it's probably lower. The car is loaded with options - A/C, power everything, vinyl roof, rallye wheels. It has a 200C transmission and the gears in the differential are unknown. The suspension is incredibly soft. It has a few surface rust spots.

My goal is to keep the car stock looking inside out but improve it. Keeping a Buick six is a must. A mild turbo setup, with TBI, a 200-4R, to increase power but keep the "economy". It currently runs at 11 liters/100km / 21mpg. I'd like to improve that gas milleage, along with much more power & fun. Eventually, a bit stiffer suspension.

This year:
* install a rallye pac cluster (found one on eBay, also found the sender for temp and oil )
* buy a "staging" Buick V-6 engine (bought one, a 1977 odd-fire )
* buy a "GN" turbo kit (bought one, eBay )
* get a camshaft ( Isky 1171-TA, bought)
* buy a 200-4R and have it rebuilt ( will go tomorrow to see one for sale)
* setup the engine in the basement, and build it all winter.
* of course, the Olds will be stored for Winter ( by end of September )

If you are worried about fuel economy, going from a 2 barrel to stock TBI won't be a huge improvement and not worth the time spent wiring tbh.

Spend the extra money and get a Sniper EFI, otherwise keep it carbureted IMHO.

well, the goal is to TBI + turbo or maybe also carb + turbo. but as you see, I have plenty others things in the works.

meanwhile, in the basement, the cats have taken over the Cutlass seats 🙂

Still think the "touring sedan" sail panels look legit 😉

Backseat noise insulation, using Noico red material. Ongoing.

so here we are now. fully soundproofed backseat & sail panels. I filled the void behind the sail panels with spray foam, and added Noico sheets behind the panels to finish this off. I hid an Irish spring soap bar behind the seat too, and you may know why 🙂

Now, I am missing some Noico sheets to finish the floor, before I install the brand new carpet. Ordered.

So there we go. carpet installed, rear seat clamped in place with an extra dose of Irish Spring 😉

Tomorrow, front seats installed.
