1991 Porsche 944 S2 - Stewie - First Impressions

If it wasn't already obvious, when my garage renovation included a dual 4-post lift, you knew the 4th spot in the garage was destined to be filled. I've been looking at cars for months now hopping all over the place from Lotus Elises, 70s era 240Zs, newer GT cars, and oddly (to some) the Porsche 944. I've always loved the look of these cars. The pop up headlights, boxy hips and 80s styling really resonated in some weird way. 

1991 Porsche 944 S2

I've seen some extremely clean ones being sold for nutty prices and some very questionable cheap ones that left a lot to be desired and everything in between. For me, buying and old car is very much about buying the owner and finding the right owner that shared my ownership philosophy can be tough. I happened to be looking at the PCA Mart when I stumbled across this 1991 944 S2 with 95K miles. It was listed as:

"Excellent driving S2 in pristine condition. Conti DWS06 tires, Konis, adjustable front spring perch w/200# front springs, M030 front & rear bars, SS brake lines, SS Dansk cat back exhaust, MOMO steering wheel, stock included, air bags disabled, AC converted to R134, blows cold, Hella H4 headlights on aux relays. All electrics & mechanical work. Clutch, flywheel & pressure plate replaced at 64,000 mi. Timing belts and rollers replaced at 85,000 mi. No cracks in dash or rips in seats. Carpets like new. Recent new front LCA's, CV joint assemblies. Car cover. Receipts for all work back to 2011. Original manuals in pouch. Spare Key. Porsche Certificate of Authenticity. CARFAX"

The car was clearly taken care of so I contacted the owner. He'd had the car for about a year and a half but the owner before him had it for 16 years. We talked about the car and the previous owner. You have to remember these cars were pretty unwanted cheap cars for a while so many were either neglected or just maintained at a bare minimum. The previous owner did everything I would've done including lots of pre-emptive maintenance and putting in a lot of money to making sure it always ran right. How someone treats a "cheap" car speaks volumes to me about how the car will be in general and that owner clearly loved this car. Nothing was left to chance. Anything and everything that needed to be done was either replaced or upgraded. This was a true turn key car. 

The engine bay was immaculate but shy of concourse clean (great since I don't have to be super careful and worried all the time). Even the spare trunk location was just insanely clean. The undercarriage continued with the same story. This is the kind of car to get excited about. There were no cracks in the dash, no rips on the seats, the carpet was mint, heck even the clock actually works. I had the guy give me a few more pictures and walkthrough videos. We agreed on a price that was a bit less than asking but a fair deal for both of us and wired the money over. 







Cold start and walkthrough (by previous owner)

Since the car seemed well sorted and even had Continental DWS tires on it so it could handle the cold, I figured I could save some transport money if I just flew down to Orlando, Florida and drove it back up so that's what my wife and I did Saturday morning.

The owner was a super nice snow bird from Canada. He likes to tinker with cars and well this car is almost too sorted for him. He sold it to fund his other 944 project where 's putting in an LS motor and making it a track car. This car was a bit too mint for him to consider that level of molestation with. I had already ordered, and started to receive, some mods for the car earlier that week so as soon as I got there I put on my Rennline phone mount so I could easily navigate home then we took off on our 1,111 mile journey home.

It wasn't long before we were driving through pouring rain and tornado warnings and I found the first "flaw" with the car. The wiper blades were a bit old and were skipping a bit unless the windshield was completely soaked. If it was just damp it didn't really clean too well but it'd be fine enough for getting home. The AC worked extremely well. It had been converted in 2017 to a Kuehl AC Compressor kit from Griffiths and is now running R134a. It got so cold I had to turn the AC all the way down to no freeze to death. The heat also worked incredibly well.

Taking a little break

Last Buc-ee's in South Carolina

We planned to stop in Fayetteville, North Carolina Saturday night and decided to make a final fuel stop at the last Buc-ee's in South Carolina on our way up. If you've never been, it needs to be on your list. This is beyond being a normal gas station, it's the best gas station ever with the most amazing food and the cleanest bathroom you've ever seen. Go watch some Youtube videos if you're curious. The next day, we finished our rather uneventful journey home and this 944 S2 which I've now dubbed as "Stewie" (S2WIE) officially joined the Steguis Motorsports fleet.  

Stewie is home

Today I also installed new 19" wiper blades all around so I'll have a better experience if I have to drive in the rain again.

From the Porsche side of things, my fleet now includes an interesting story of the evolution of Porsche starting with the 1983 911SC that was supposed to be the final year of the 911 to be replaced with the new watercooled Porsche 928 "transaxle" car . The retirement of the 911 never happened and continues to this day. The 944 was created with fewer cylinders than the 928 and was made until in 1991 when the final iteration of the 944 line, the 944 S2, was released. The S2 largely retained the same body in the final years but had adopted the 944 Turbo bumpers, brakes and transmissions and got the 3.0L NA 4-cylinder, the largest displacement 4-cylinder engine of its time. The 1991 944 S2 in particular has more in common with the 968, the last of the transaxles that followed until 1995, than the earlier 944. The Boxster the took over in 1996 followed by the Cayman in 2005 became the mid-engine 911 alternative. 

First Impressions

Well after spending over 1100 miles of driving over 2 days driving through sun, rain and temperatures that went from 86F all the way down to 45F these are my thoughts and experiences:
  • This is a terrific car. It was everything the seller presented it to be and more. The car ran smoothly with no major issues during the entire journey.
  • This car feels absolutely solid. It's a 32 year-old car but lacks any rattles or squeaks. It's in fact quieter and more comfortable than my 4 year old Mini Cooper S.
  • You can feel the distinct balance offered by the front engine but rear transmission transaxle layout especially in the corners. There is terrific steering feel and feedback even with the hydraulic steering.
  • Brakes are excellent at any speed
  • This is probably my slowest car. At around 200hp at the crank, it only puts down probably 160 to the wheels and weighs as much as my Cayman so it's not winning any drag races, at least not in NA form. However, I can feel in the corners how well balanced this and it's confidence inspiring evening in torrential downpours. 
  • The cruise control is a bit temperamental. Sometimes it won't engage then it will again. Seems to be a common issue that I may or may address. Other than this road trip, I really don't use cruise control anyway.
  • The H4 headlights are ok but certainly not the brightest. I've got an upgrade ready to install soon. 
  • The Sony radio from over 10 years ago is fine for basic bluetooth function and I'm glad we had decent audio on the drive home but I can't wait to put on my period correct looking Blaupunk Frankfurt to replace it.
  • Clutch engagement is on the high side. It's not because of a worn clutch, apparently they're like this but there is some adjustment so I may try to have this engage a bit lower.
  • The engine is pretty quick revving and I feel like it's got a slightly lightweight flywheel. The revs climb and drop pretty quickly when I clutch in and blip the throttle. Took a bit to get used to getting a proper rev match in. 
  • Kudos to whoever setup the suspension and aligned it. The ride is firm on the Koni yellows but comfortable and responsive and the car drives straight as an arrow even with no hands on the wheel.
  • The 21 gallon fuel tank is insane and I got between 27-30mpg on the highway. We spent around $150 in fuel going from Orlando FL to North Jersey.
Overall I'm super happy with this purchase. I bought it for a price where if I wanted to get out of it I wouldn't lose any money but I think this one is staying with me for a bit. It offers a very distinct driving experience from my other cars and call me a little child but man, I do love those popup headlights.

Maintenance Update: Oil Change on Chopper and Fluid Film

We always get the undercarriage fluid filmed before the winter but it really smells like farm animals when you do that so I wanted to get the oil change done first.

Then took the Jeep to my friend Steve DeRosa to get the undercarriage covered in fluid film for rust prevention.

Another year, another coating of fluid film

Trunk Coolant Cap

I've been hearing a bit of burping recently on the back of the Cayman if I don't drive the car often enough. The last time I heard that noise (but much louder) was when I accidentally left the cover where the oil and coolant fillers are located in the trunk open. From what I understand this is part of the natural burping process as the coolant expands, however, my understanding is that the rubber gasket on the cap can start to dry up and fail over time so I figured now would be a good time to replace it. 

New coolant trunk cap

They're cheap enough to replace and this one is now 16 years old so it's probably overdue.

Haltech gaugeART CAN Gauge

When I was building Bumblestook for autocross, I went a bit wild with everything and got a Haltech Racepak IQ3 dash installed. It was great for datalogging and also seeing important sensor details like oil temp and pressures so I've left it on ever since. However, more recently it's been bother me that I haven't been able to enjoy seeing my stock S2000 dash. I've always loved how it looks and from a practicality perspective, not being able to see my fuel gauge can be a problem. Eventually I found out that Haltech teamed up with gaugeART to release a CAN gauge that'd be able to display any number of data points from my Haltech ECU all in a nice 52mm package.

Since I've been busy with events all year I didn't want to mess with installing this but now that I'm mostly done for the season I figured I'd finally tackle this project. First up was to remove my Racepak dash. This has always been removable but I wanted to fully disconnect it which meant getting rid of the mount for it as well as yank out all the cables that went to it. 

removing the steering wheel to remove the bracket

This spiraled into me having to remove my steering wheel and indicator stalk mounts so I could get to the bolt securing the bracket. Then I had to remove my center console and radio to start yanking out the USB cables and momentary switches wired in to control and program the dash.

Weight savings

Unfortunately, it was at this point that I realized that the new gauge came with a DTM-4 connector and I needed an 8-pin Tyco adapter to connect it to the Haltech CAN hub I have going to my ECU. This would normally require an adapter and I'd have to wait a few more days to complete this project. Thankfully I had a spare Tyco connector and pins from when I was trying to hook up my Solo2 datalogger. This took longer than I was hoping because I wired up the connect just like the Racepak dash was wired and it wouldn't turn on. Eventually I looked up the wiring diagram for the 8-port Tyco and realize that ground was pin4 and CAN low was pin 3 and I had them the other way around. Not sure how the racepak was working unless the wire colors were different.

I verified everything was working then used my iPhone to configure the gauge. Once I knew everything was working I put everything back in place and mounted it to my a-pillar using an Autometer single gauge pod. I'd a pretty clean install and I'm glad there's only a single gauge so it's not ricey.

Season Ender at Watkins Glen

This is our last year at Watkins Glen with S2K Takeover so I wanted to bring Bumblestook out. While the weather wasn't overly cold, day 1 was just rain all day making it a bit miserable especially as it would stop raining and then rain again just as the track was showing some signs of drying. 

Watkins Glen International - 10-16-2023

I didn't care though, a wet track day at The Glen is still loads more fun than a day at the office so I went out almost every session and just being mindful of the significantly reduced grip. After all, wet driving is excellent driver training.

Watkins Glen International - 10-16-2023

We went to Grist Iron Brewing Company for dinner which would've been a really good spot with a view but alas the rain just kept relenting.

Day 2 was nice. The sun actually came out to dry the track by the 2nd session. I don't know if the rain the day before was messing with my head or my random oil pressure warning light kept distracting me but I found it hard to get really comfortable and I clocked in my best time that was 10 seconds slower than my time last year in the Cayman. 

Watkins Glen International - 10-17-2023

I also had a weird thing happen where I got some oil spray from my oil catch can. Somehow some oil had worked its way through the filter and then got sucked through my hood vents onto my windshield. That also was not comforting. I'm going to spend this winter going over every aspect of the car. My current theory is that the check valve for the catch can drain isn't opening up quickly enough. I don't think I even need that valve so I may just ditch it. 



Some oil escaping my catch can

Overall those, it was such a blast and I'm going to have to figure out another club to run with next year since I need to get my annual "Glen" fix. 

Another successful event at The Glen

Cayman Oil Change

Oof, realized that while I haven't put many miles on the Cayman it's been over a year since I changed the oil. I don't sweat this too much since I use good quality oil but still, I generally don't like going beyond a year on oil regardless of mileage. 

Draining oil

I didn't really like my little Harbor Freight lift oil drain too much since I was worried that the higher flowing and higher capacity Porsches might overflow the smaller funnel so I got a new US made Lisle 8-Gallon Oil Lift Drain instead. It features a much wider mouth funnel and I also got the no splatter pad for it so that any draining oil won't just bounce right out. It works super well and I'm very happy with it.

I then put in some fresh Driven DT-40 and we're now good again.

First oil change for Arturito

Ok well this isn't really the first oil change but it's the first oil change done by me. According to the records, the oil was changed before it was sold to me but since I have no idea what oil is in there, I really wanted to get this oil change so this was a bit overdue for me to get my hands oily.

New oil filter in

It's a bit more fiddly that my other cars since there's a separate drain for the oil filter housing. Other than that though it was pretty much a breeze. 

Noting torque settings for the future:

Oil drain bolt - 25Nm (17mm bolt)

Oil filter drain screw - 5Nm (T50 Torx) also, accidentally pushed too hard with my ratchet and stripped the plastic teeth in the new drain screw so I'll have to pull the whole housing out first next time I do this and extract it with something else.

Oil filter cover - 25Nm 

Maintenance Update:

- 5L Liquimoly 0W-20 (supposed to take 5.5 quarts. Will drive the car around to get warm so the computer can measure the actual level before I add more)

- New oil filter drain screw

- New oil drain copper washer

- New rubber oil drain gasket
