Turbo LS-Powered Oldsmobile Cutlass Supreme Packs Monster Power
Turn-key Oldsmobile will get everyone’s attention, driving into the track and running 9s.
There was a point in time where General Motors cars from the mid-1980s were mocked for their lackluster performance, but cars like the 1984 Oldsmobile Cutlass Supreme have proven to be a great platform for a big-power build. The 1984 Olds shown here was recently listed for sale in the LS1Tech Marketplace by “Nate Weimer“, and if you are serious about a street-friendly, 9-second car, this G-body might be the answer, packing over 1,000 horsepower on E85 from the LS-based V8.
When the OP first posted his 1984 Oldsmobile Cutlass Supreme for sale in the marketplace, he provided the following basic information on the car.
Paint is older has some clear coat fade on the hood and roof. Interior is in good shape no mechanical problems has the fuel tech touch screen where you can change tunes, data log, see all the gauges ect. Currently has a 93 octane 18 psi tune and e85 26 psi tune on it prob makes 800ish on pump 93 and 1000-1100 on e85. NO OFFENSE TO ANYONE BUT DO NOT CONTACT ME IF YOU DONT HAVE THE FUNDS TO PURCHASE. I’ve had 26273883 people messaging me asking questions about the car then telling me they gotta wait until this sells or some other ****. Sell whatever you need to before contacting me. If I didn’t reply before my bad people blow me up about the car it’s hard to respond to all the messages.
$20,000 cash only not open to offers this is a turnkey car that will run mid 5s as is and low 5s with some suspension tuning and can be driven to and from the track. Call or text 513-709-9727 no trades unless it’s something worth more straight up that you shouldn’t really be trading lol c6z v2 ect.
He also provided the pictures here, along with a few more that we did not include.

Big Performance Potential
We don’t know if those horsepower numbers are at the wheels or at the crank, but with the mention of 9-second capabilities, this Oldsmobile is making big power. A 1984 Cutlass Supreme with the V6 weighed in at just 3,200 pounds and while there is some weight removed from the interior of this car, there is no question that the turbocharged LQ4 engine adds some weight. As a result, the car is probably about the same weight as it was when stock, if not a little heavier.
Based on a simple eighth mile-to-quarter mile conversion chart, a car running in the high 5-second range in the eighth, say a 5.85, would be running in the 9.1 range in the quarter mile. A 5.50 in the eighth is in the 8.5 range and getting into the low 5-second range would nearly put the car in the 7-second quarter mile range. That is crazy-quick, but even if it “only” runs in the 9-second range in its current form, it’s not going to lose to many other cars on the street.
So, if you have $20,000 to spend on an automotive toy, you could have a classic Oldsmobile that everyone will talk about after seeing you rip down the local track.
