Enhancements / Modifications - 92 SC |
Custom Low-Amp Alternator Due to the mileage on the car, I decided to add the alternator to the list of parts that should be replaced (since Saturn alternator failure seems to be a more common problem). With all of the wiring & electrical accessories that were junked in favor of weight reduction (HVAC, pwr windows, pwr mirrors, pwr locks, sunroof, mouse belts, radio, headlights, rear defog, dome/trunk lights, etc...), the alternator no longer needs to produces as much current as it used to. The stock alternator was replaced with one custom-wound to produce 63 amps. Add to that the 20% underdrive pulley (installed in pic at left), and that should put current output right around 50 amps - plenty to run the PCM, gauges, and fuel pump. And, it'll require less of the motor's power to turn it. |

Since I had seen a huge variety of high-amp & custom alternators being sold on eBay by Beavco, I knew they'd be able to put a low-amp model together. I was very impressed by this unit assembled with all new components, and shipped fast for a great price. Will the low-amp alternator combined with the underdrive pulley
actually free up a measurable amount of horsepower? That's a good question.
Even though Boers has hp gains listed on his website, I really don't have any
expectations. Hey, even if it frees up one horsepower, it all adds up. |
Hardened Tapered Wheel Bearings With the car's high mileage and all the track time in its future, the front wheel bearings needed replacement. I got these from SPS, and also have them installed on my 94 SC2. These roller bearings are a bit more heavy duty than the stock ball bearings. A hydraulic press is required to remove & reinstall the bearings in the hubs. It's funny how one job sometimes leads to another. :) |
Added 12/2001 |
10/2002 - During an alignment at my local Saturn dealer, the tech realized that there was some play that shouldn't have been there when he grabbed ahold of a front wheel. I had thought that one of the bearings was bad, but he reached for the impact wrench and let loose with it on the axle nut. Apparently, the axle nuts need to be incredibly tight (even tighter than the factory torque spec) or the wheel bearings have play and will self-destruct over time. After hitting the nut with the impact, all was well and the play was gone. |

Sparco Hood / Trunk Pins Plans for the car include weight reduction everywhere that is possible, and part of that will require removal of some of the hood and trunk lid structure, as well as the trunk lid's latch and torsion bar hinges. Of all the pins I'd seen, these looked to be made with the best quality. Where most others of this captive pin style were made out of aluminum, these are made of steel and feel to be of pretty nice quality.
Update: They were blasted and powdercoated
mirror black (photos can be seen on my powdercoating
page). |
I've had a chance to try this seat out at a race shop along with quite a few others. The seat weighs 16 lbs, which is significantly lighter than the stock seats. It's also very comfortable with nice support, and a great deal for the money. I decided to initially get only one seat to make sure the fit in the car was the way I wanted it to be before I sprung for a passenger seat. Corbeau also sells tracks/rails to mount this seat in a Saturn, but it seems that they don't produce a run of them often. If you consider one of these seats, be sure to take that into account. It is possible to remove and modify the tracks/rails from your stock seat to fit, but it's not an easy job. It required seriously destroying the factory seat, lots of cutting and test fitting, and a bit of welding too. I don't know how much I trust the end product, so I've got a set of Corbeau tracks/rails on order (and will likely have to wait quite some time to receive them). |

1/2003 - Received the Corbeau rails, and after some modification, they were installed. Details can be seen HERE. Update:
After verifying that the seat fit the car, and the driver fit the seat, I
ordered a second seat from
MotorsportSeats once again. |

Konig Helium Lightweight Wheels (15" x 6.5", 40 mm offset, 11 lbs) Most OEM Saturn wheels weigh between 16 and 19 lbs. (More info is available on my wheels page.) Since the weight of the rim is unsprung as well as rotating, a reduction of 5 lbs per corner will have a large effect on how the car and suspension performs. Plus, it makes the whole car lighter too. For a more technical description of the affect of wheel weight on performance, take a look at this article. I found these wheels offered on GroupBuyCenter.com by G-Force Performance for an
amazing deal. When holding and looking at these wheels, it's hard to believe that
they'll be strong enough to withstand some rough off-track excursions that are sure to
occur. I'll be sure to report on how they hold up after I get some track time on
them. |
8/2002 - I used these wheels/tires on my 94 SC2 at Gingerman
Raceway during the 2002 SPC Rally. I had one
off-track excursion where the car left the track and went sideways through rough dirt and
grass at a pretty good speed. I'd give the wheels one mark in the plus column for
durability, but only time will tell. The intense brake heat caused one of the plastic wheel center caps to deform and come apart (you can see a photo HERE). The composite plastic hubcentric ring (which is more durable than the center caps) that was supplied with Konig no longer fits snug into the wheel. While it will still work just fine, the heat obviously affected it also. 5/2003 -
Ordered two additional
wheels to use with some Mickey Thompson ET drag slicks that I'd purchased.
See my writeup of them HERE. |
Kumho Race Tires (Victoracer V700, 205/50-15) I've been using these tires for quite some time on my '94 when I'm out on the track. These are classified as competition tires (DOT legal), and perform best when heat-cycled and shaved (even though there is barely any tread on them). The treadwear index stamped on the tire is 50, and you can tell that the rubber is extremely soft. The cornering grip from these tires is amazing. If you've never driven with race tires before, it's hard to believe that tires could make such a huge difference in how the car handles. I removed these tires from my 19 lb stock teardrop alloy wheels and mounted them on the Konig 11 lb wheels - a change that should really make a difference. My last set of these
lasted 600+ hard track miles and 10 events over almost 2 years. That
amounts to about 50 heat cycles, and was a surprisingly long life. (You can see
a picture of new vs. old HERE, and a
look under the rubber HERE.) |

Traction didn't fall
off all that much as the tires aged or became more worn. I'll continue
to use these tires on the track, as they are a great value for a whole lot
of traction. 7/2006
- Set #2 of these was pretty well worn and one started to show its cords at
the end of the 2005 season, so it was time for set #3. I was again
able to get several years and quite a number of events out of this set, and
I continue to be amazed by how many miles they're good for before they're
used up. They're a great tire for the money. |

H&R Front Wheel Spacers With the Carrera strut housing's
larger-than-stock body, lots of negative camber, and a wider aftermarket rims/tires, front
spacers will be necessary to get everything to fit. Even with stock tires, rims, and
camber, you can see the lack of clearance in this
picture. These spacers go between the hub/rotor and the
rim, and will add 5mm of clearance between the inside edge of the rim/tire
and the strut housing. |
