Another W41 car followed my truck home... (nope on the 56k)

I haven't been online as much in the last couple months due to lots of work stuff and getting ready for a nice little deployment to an overseas desert paradise that's coming up pretty soon, but that hasn't stopped me from expanding my fleet of cars. Speaking of which, I almost made it a year without buying another car, but darn that late night craigslist browsing. :lol:

Last month I drove my truck back up north to have some body work done at a shop that's worked on my family's cars for a number of years. When I got up there I was online and ran across another '93 Oldsmobile Achieva SCX for sale in Utah. While driving my dad's truck back to SoCal along with my mom we stopped by late at night to look at it and a week later when my dad was driving my truck down he picked it up for me and towed it to my house.

For those not familiar with the car, and I'm guessing that's most people, it was a special version of the Achieva and was only made in limited numbers in '92 and '93. The Achieva SCX W41 replaced the Cutlass Calais 442 W41 in the Olds lineup which had been introduced in that car's last year of production for 1991 (both were built on the same basic GM N-body platform). They were essentially a showroom stock race car for those interested in racing SCCA showroom stock and was also used to homogulate the car for other racing series. The SCX was campaigned quite successfully by GM-backed teams in the IMSA Firehawk Series as well as a World Challenge car. Below is the text from the press release package that I have from when the then new '92 Achieva was released.

Oldsmobile Announces New Achieva SCX Model

LANSING, MI … Beginning in the spring of 1992, Oldsmobile's rich engineering heritage meets today's smart, contemporary vehicles with the introduction of the Achieva SCX high performance model.

Featuring the W41 high performance package and specific graphics, the SCX is based on the all-new Achieva Sport Coupe model.

At the heart of the new SCX model is a 190 horsepower high output Quad 4 engine. This top-of-the-line Quad 4 features a specific W41 camshaft which allows the engine to rev higher, producing greater usable power, and a stiffer block plus a new front cover for smoother, quieter operation.

To handle the increased power and provide a controlled and confident ride, the Achieva SCX features unique 14 x 6.5" inch aluminum wheels, new 215/60VR14 speed rated tires, a rear axle with a wider track than other Achievas, twin rear stabilizer bars and a 30 mm front stabilizer bar.

In addition, a Computer Command Ride (CCR) system specifically tuned for the SCX will be standard equipment. CCR allows the driver to adjust suspension damping depending on driving conditions.

A smooth-shifting 5-speed manual transmission with a specific .81 5th gear and concentric slave clutch, plus a reduced back pressure exhaust system, round out the content which combine to make the SCX a balanced performance coupe for today's discriminating buyer.

Outside, the SCX is distinguished from the Sport Coupe by full body color fascias and rocker moldings, W41 and SCX decals and a silver accent stripe. When combined with Achieva's sleek exterior styling, the SCX treatment provides an aggressive yet refined appearance.

The name W41 is a derivation of an historic Oldsmobile name and one synonymous with power and innovation. In January of 1968, Oldsmobile released the W31 option for the F85 and Cutlass Supreme coupe to a world hungry for more powerful engines. The W31 option gave buyers a potent 325 horsepower 350 cubic inch V8 with a choice of a 3-speed, or close- or wide-ratio 4-speed transmission and the choice of a 3.91 or 4.33 rear axle.

In 1991, Oldsmobile updated the W31 name to reflect use of the much-acclaimed Quad 4 engine. In the first year, W41 equipped Oldsmobiles captured the Manufacturer's championship in the IMSA Firestone Firehawk series.

For 1992, the W41 option returns to street and track in the all-new Achieva.
That summarizes most of the major differences between the SCX compared to the basic Achieva. If you've ever driven a base model Achieva they were a marginal car at best compared to contemporary compacts (especially the sedan). While the regular models were ho-hum, GM did a lot of suspension development work on the SCX and it showed on the track. There's a short review of the car on youtube from the PBS MotorWeek series at this link.


The following are some pictures of the car I picked up. It is one of the 500 SCXs made in 1993. The chassis has just under 200k miles but much of the mechanicals were replaced by the previous owner. He picked it up from someone that pulled the W41 engine for another project along with some of the underhood components. He replaced it with a GM reman engine along with a new clutch, radiator, A/C compressor, hoses and a bunch of other stuff to include some suspension pieces, brakes, and newer tires (all of which has been done in the last 7-8k miles). Despite the mileage the car is pretty clean with no rust or major issues. The paint when viewed in person is pretty chipped on the front end and is not as glossy as new but I can't complain for a 17 model-year-old car. The interior is also in pretty good shape and everything still works on the car.

The only thing it will need pretty soon is a new set of struts and shocks. It still has the factory electronically adjustable units and the fronts are getting a little soft. Not sure if it will get some KYB or if I'll track down the OEM units ($$$). The reman GM engine is a regular High Output Quad 4 and not the W41 version (which was 190 hp in '92 and slightly less at 185 hp in '93 due primarily to a change in the exhaust manifold and head). I've got a stack of W41 cams and computers from other SCXs in storage that I may eventually dig out and swap in but it runs and drives fine as-is. I am planning to change out the regular black H.O. IDI (integrated direct ignition) cover for a red Olds W41 cover.

My plan is that it will become my new daily driver once I get back stateside. I'm well past the point where I should be buying more cars so something has to go. More like a few things are going to get finished up and sold, but the Achieva will be replacing my '87 Fiero for DD duty. It was a clean, one owner car with under 110k original miles but I made a deal with myself that if I bought anything else something would have to go.

The regular Achieva SC came with a set of 16" wheels that filled out the wheel wells a little more than the stock 14" wheels on the SCX. They do exaggerate the gap "slightly". :lol: The 215/60-14 tires are the same size as used on my Citation X-11s and are getting pretty hard to find. There are no more V-rated performance tires like it came with stock and only a few all-season tire choices now. This car won't be raced on the track but if it ever did I'd have to swap on a set of larger wheels to get better tire choices.

I presume it would have cost more if the original W41 engine was still inside it? From reading "He picked it up from someone that pulled the W41 engine for another project along with some of the underhood components." I presume that he could not get as much as he may have liked?

Thanks for the comments. On the engine, it does have a High Output "LGO" code Quad 4 and the horsepower difference is only ten less than the W41 engine. If it had a Quad OHC (SOHC) or the V6 or something whacky it might not have appealed as much, but I've got quite a few sets of W41 cams and computers which is what gives the bump in power. Since this will be a daily driver I'd much rather have the new reman engine and swap in my parts if I want than a high mileage original engine.
