I had always been a fan of the Porsche 944 turbo, but when I came across one that had been severely neglected and was in desperate need of long overdue TLC (it was also being advertised for only $5000 CAD) I knew I had to take on the challenge. This particular Porsche 944 Turbo had received a couple of less than desirable paint jobs over the years, some very interesting design/color choices and seriously questionable modifications. It was clear that it needed a lot of work, but I was determined to bring it back to its former glory. After being told the only major thing mechanically wrong with the 944 Turbo was a potentially bad fuel pump, I decided to make an offer. I learned a lot of lessons that day. Not only was the fuel pump bad but nearly everything else was as well.

Porsche 944 Turbo – A Diamond in the Rough
As I began the restoration process, I quickly realized how underrated the Porsche 944 turbo really is. Despite its reputation for being a less popular model, I found that it had a devoted fan base, excellent aftermarket support and was actually becoming more popular in recent years. In fact, I had heard of several examples that had sold for upwards of $80,000 USD and even one for $135,944 USD on BaT, which only served to fuel my passion for bringing this particular car back to life.

Jerry Seinfeld, buys a 1989 Porsche 944 Turbo
One of the most exciting developments during the restoration process was when I learned that even Jerry Seinfeld, who is a large Porsche collector, had jumped on the Porsche 944 bandwagon. In early 2019, the comedian and car enthusiast purchased a 1989 Porsche 944 Turbo, further proving that this model was on the rise in popularity.

Progress on the 1989 Porsche 944 Turbo – No Going Back
A lot of progress has been made on the Porsche 944 Turbo in the five years I’ve owned it. From discovering that the fuel pump was seized to replacing the entire engine due to a bad rebuild, there was hardly anything that I didn’t have to fix or replace. When I first saw the car in person, I noticed bondo cracking in the paint job, poorly built hood vents that caused the hood to collide with components in the engine bay, royal blue powder-coated factory clubsport wheels (why?), a cracked windshield, and rags shoved behind the driver’s side a-pillar where a two-gauge pod that housed a boost gauge and an oil pressure gauge was installed. The rag was there to catch the leaking oil from the poorly installed oil pressure gauge.



Breakdown of the problems I discovered with the Porsche 944 turbo:
- Fuel Pump Seized
- Fuel return line pinched shut
- Clogged Injectors
- Corroded Bosch fuel pressure regulator and fuel damper
- Sludge in fuel tank
- Fuel tank threaded insert broke out of plastic fuel tank
- Corroded fuel sending unit (saved)
- Fix bypassed fuel pump wire
- Broken connector under fuse panel preventing fuel pump relay to get signal from computer
- Naturally Aspirated 944 DME, removed and replaced with a Turbo DME
- Low compression in engine – cylinder walls scored from bad rebuild
- Many relays in wrong positions in fuse panel
- Battery cables burnt and shorting due to poor placement
- Starter blown from shorted battery cables
- Oil leaking behind driver side A-pillar due to poorly installed oil pressure gauge
- Broken windshield
- Lot’s of bad body work and cracked bondo
- Damaged weather seals
- All front body panels damaged/needing replaced
- Numerous hoses needed replaced
- Most hardware needed refinished
- Stripped stud on wheel hub
- Numerous, broken, missing, or poorly painted interior pieces.
- Half removed headliner
- Horn didn’t work
- Headlight motor didn’t work
- Shoddy wiring and connections
- Several joints and poorly run power steering hose from reservoir
- + lots more
