914 Owner’s Guide
What to Do With Your First Porsche 914
You bought the car. Now let’s make it drive like a 914.
Last month, in How to Buy Your First Porsche 914, our advice was simple: buy the body first; everything else can be fixed. A sound body gives you something worth building on. The mechanical pieces can be serviced, restored or upgraded as you learn the car.
So, let’s assume you found a solid car, brought it home, spent an inappropriate amount of time standing in the garage looking at it, and most importantly it runs. If it doesn’t, stay tuned; that is a different article coming soon.

This is where new owners often get carried away. They start shopping for a bigger engine, pull half the car apart because one bushing looks tired, or park it on jack stands while planning the “perfect” build. Five years later, it still hasn’t gone around the block. Your first goal should be much simpler: make the car enjoyable to drive. A properly sorted 914 does not need huge horsepower to be fun. The steering, brakes, low weight and mid-engine balance are the whole point. Remove 50-plus years of wear, tired rubber and questionable maintenance, and let the car show you what Porsche intended it to be. |
There's a lot of learning in the first few months of ownership. Sort the basics and the 914 will tell you what it wants next. |
1. Change the Oil
Indeed, we’ll start with the least exciting job on the list: change the oil. Unless you personally watched the previous owner service the car yesterday, assume it needs to be done.
Get a clean start. An oil change with VR1 and a fresh Bosch filter is the least glamorous hour you will spend on the car, and one of the most useful. |
You are establishing your own maintenance baseline so you know what is in the engine, when it went in and what the old oil looked like when it came out. Our 914 Oil Change Bundle includes six quarts of Valvoline VR1 20W-50 for a standard four-cylinder car, a Bosch filter and a fresh drain-plug washer, with eight quarts supplied when the oil-cooler option is selected. It will not garner any attention at Cars & Coffee, but it gives you a clean starting point. |
PMB Pro Tip: Don’t drain the old oil without looking at it. Check for a strong fuel smell, metallic glitter or debris, and cut the old filter open when the engine’s history is truly unknown. Why do we recommend VR1? Because it already contains the high-zinc anti-wear package older flat-tappet engines need, so don’t stack extra additives on top of it unless your engine builder specifically asks you to. More is not automatically better; even Valvoline warns that excessive zinc can be harmful.
2. Make the Brakes Right
If there is one area where we have strong opinions, you can probably guess what it is.
A 914 should have a great brake pedal, not one that firms up after a pump, pulls when cold or merely feels “good enough.”
|
Our complete Porsche 914 Brake Bundle is essentially a reset button. It includes restoration of all four calipers, four Sebro rotors, the applicable wheel bearings and seals, DirectFit soft hoses, PMB-C pads and new caliper hardware. The calipers are completely disassembled, replated and rebuilt with new ATE seals and dust covers. The result should not simply be a car that stops. It should be a firm, predictable pedal that gives you confidence every time you use it. |

The “While You’re in There” Stuff
Hard Lines:
We do not automatically replace every hard line simply because the car is old, but we inspect all of them. Corrosion, rounded fittings, questionable repairs or a line that twists during removal are good reasons to replace it. PMB’s DirectFit hard lines are 3D-scanned from original lines and CNC-bent to follow the factory routing. Complete kits are available for ’70 to ’72, ’73 to ’74 and ’75 to ’76 cars.
Master Cylinder:
Use the same judgment with the master cylinder. If its history is unknown, it is leaking or the pedal behavior gives you reason to question it, this is the time to deal with it. With the system already apart, a fresh 19mm master cylinder is cheap insurance compared with doing the job twice.
PMB Pro Tip: If a five-lug conversion is already in your long-term plan, decide before buying fresh four-lug rotors and wheel bearings. With the brakes apart and the hubs accessible, this is the cleanest time to do it and it keeps you from buying the same wear items twice. PMB offers bolt-on five-lug conversion packages for both early and late model 914s, split at 1972.8. Five-lug does not create more braking power by itself, but it opens up factory wheel choices and gives you a cleaner path toward later brake upgrades.
3. Put Good Tires on It
One of the quickest ways to improve an old sports car is to get the ancient tires off it. We do not care how much tread they have. A tire can look beautiful in the garage and still be hardened rubber that has no business being asked to show you what a mid-engine Porsche can do.
A classic 15-inch wheel with real sidewall is what the chassis was designed around. The sidewall is part of the suspension. |
Age does that on its own, driven or parked. For a narrow-body 914 on 15-inch wheels, we have come up with a simple Good / Better / Best approach. You can spend a fortune rebuilding the suspension and still dislike the way the car drives if it is sitting on hard or poorly fitted tires. Start with the four patches of rubber touching the road. |
- Good: Radar All-Season GT, 195/65R15: A budget-friendly modern all-season tire with predictable road manners. It gets an unsafe or worn-out set off the car without turning the purchase into a major investment. At the time of writing, the complete set is an amazing $307.95.
- Better: Continental SecureContact AW, 195/65R15: A more refined all-weather choice with a strong balance of comfort, wet-weather ability and everyday manners for the owner who plans to put real miles on the car.
- Best: Pirelli P6000, 195/65VR15: The enthusiast choice, with a more performance-focused response for the warm-weather driving that makes a sorted 914 so enjoyable.
PMB Pro Tip: Bigger wheels are not automatically better. The tire sidewall is part of the suspension, and the 914’s light, communicative character works beautifully with a small wheel and some real sidewall. A larger, heavier wheel with a thinner tire can make the ride harsher, while the wrong width or offset can add rubbing and steering kickback. Narrow-body rear clearance is especially tight. Unless the car has flares or a specific performance goal, we would rather see a light 15-inch wheel with a properly fitted 195/65R15 than a larger wheel chosen for looks alone.
4. Get the Suspension Back Under Control
This is where a good 914 starts becoming an amazing 914. Many are still running suspension parts installed five decades ago, and owners gradually accept the bouncing, wandering and vague steering because that is how their car has always driven.
Familiar does not necessarily mean correct.
Bilsteins or Konis, Front and Rear
For a 914-4, Bilstein B6 front inserts and rear shocks provide modern damping without changing the basic character of the car. You are not trying to make it ride like a modern GT3. You are removing decades of bounce and float so the chassis can settle and do its job again.
Koni Sport front inserts and rear shocks take a slightly different approach.
|
Their adjustable rebound damping lets you fine-tune how quickly the suspension extends and settles after a bump, a corner or a change in direction. Keep them toward the softer end for a compliant street car, or gradually add rebound to better control body movement when running stiffer springs, driving more aggressively or spending time at an autocross or track day. KONI’s 914 Sport setup is suitable for both street and performance use, with external adjustment available on the front inserts. |
Koni's adjustable rebound is the whole argument for the brand. Start it soft and add as much rebound as the car asks for. |
The important word is gradually. The adjustment is not simply a soft-versus-hard ride knob, and turning it all the way up does not automatically make the car handle better. Too much rebound can keep the suspension from recovering quickly enough between bumps, making the car feel nervous and reducing grip on an imperfect road.
If you want to install a quality damper and simply enjoy the car, the Bilsteins are hard to argue with. If you enjoy dialing in the chassis, plan to experiment with spring rates or want more control over how the car responds, the Konis give you that additional tuning ability. Either choice is a major improvement over a tired set of shocks that has been bouncing around under the car for the last few decades.
Want Adjustable Rear Ride Height? Do It Now.
If you already want control over rear ride height and spring choice, consider the Ground Control adjustable rear spring kit while the shocks are off.
Its threaded collars make adjustment straightforward, and spring rates can be selected around how the car will actually be used. Combined with the 914’s adjustable front torsion-bar suspension, it lets you set the car properly at all four corners instead of hoping a fixed rear spring lands exactly where you want it.
Necessary for everyone? No. Very nice on a car you are already sorting? Absolutely.
Replace the 50-Year-Old Rubber
Inspect the control-arm bushings. If they are cracked, dry-rotted, sagging or clearly original, they have done their time.
For a street-driven 914, we prefer stock-style rubber at both ends because it preserves the compliance that makes the car pleasant and communicative on real roads. PMB offers rear bushings in stock and race compounds, but 95 percent of the 914s we restore receive the stock compound.
PMB Pro Tip: Harder is not automatically better. Race-style bushings can hold the suspension more rigidly, but they also remove the compliance Porsche built into the car. On a street 914, that usually means more noise, more kickback and a harsher ride without making the car more enjoyable. We have built and driven them both ways. Unless the car is primarily for track use, we recommend good stock-style rubber at both ends. A street car should make you look for the long way home, not brace yourself for every pothole. Something to think about: your 914 shares the same front suspension you’ll find on a 911 RS… a car heralded by the automotive press as the “King of the Hill” until the 996 GT3 hit the market!
Check the CV Joints While You’re Back There
Do not replace the CV joints automatically. Inspect the boots, check for play or noise and look closely at the cleaned parts.
When replacement is necessary, we prefer GKN/Loebro CV joints. PMB’s versions are pre-machined with the correct roll-pin holes and gasket groove for the 914, and the GKN joints provide the articulation these cars require. This is not a job you want to do twice.
Two Suspension and Steering Upgrades We Really Like
Once the maintenance is handled and the suspension is healthy, there are two upgrades we recommend often because both can make a good street 914 feel noticeably more precise.
An Adjustable Front Sway Bar
An adjustable front sway bar is not required, but it is one of the best tools for fine-tuning how the car responds. The through-body design offers a broad adjustment range, and adjustable drop links let the bar be installed without preloading the suspension.
For a street-driven 914, 19 to 19.3mm is about as far as we would go. A larger front bar can make sense on a dedicated track car as part of a complete suspension package, but simply fitting a huge bar to a street car can add understeer, reduce front grip and make the ride harsher. Start with a healthy suspension, use a sensible bar and begin at the softer end of its adjustment range.
We think the factory 15mm bar is perfect and we understand the appeal of finding and restoring an original factory setup, but the numbers usually stop making sense. A complete used set can easily cost $600 or more before restoration. Once the arms are cleaned and replated and you replace the bushings, drop links, brackets and missing hardware, you are often beyond the cost of a brand-new Tarett or equivalent adjustable system. Why go 19mm then? If it is adjustable, the arms are longer and they allow you to tune it back down to factory specs while dialing in the perfect handling combination.
The hollow adjustable system we currently offer is $625 and gives you new parts, adjustable drop links, a wide tuning range and no mystery wear. Unless factory originality is the goal, that is where we would spend the money.
Turbo Tie Rods
This one is different: we put Turbo tie rods on every 914 we build.
Out with the old and in with the new spherical Turbo Tie-Rod end. What the front tires are doing now reaches your hands. |
The original 914 tie-rod setup uses rubber at the inner joint to isolate vibration and road shock. That was a reasonable comfort choice when these cars were new, but after 50-plus years that rubber can introduce noticeable flex into the steering system. Turbo tie rods eliminate that rubber connection and replace it with a much more direct ball-and-socket joint. |
Porsche developed this style for the original 930-generation 911 Turbo, which was unveiled as a production model in October 1974 and launched globally in the spring of 1975. On a car with much more speed and tire underneath it, a more direct steering connection made sense. Fortunately for us, the same design works beautifully on the 914.
That matters because one of the best things about a 914 is the light, direct steering and the amount of information it gives you through the wheel. Removing unnecessary rubber from that connection makes the steering feel tighter, more immediate and more connected to the front tires.
You turn the wheel. The car answers.
That is exactly how a 914 should feel.
PMB Pro Tip: Do the alignment last. Set the ride height, install the tie rods and reconnect the sway-bar drop links without preload; then set the toe and the rest of the alignment. Start the bar on the soft side and change one thing at a time so you know what actually improved the car.
Now Go Drive It
None of this is about turning your first 914 into a race car. It is about giving it a fair chance to show you why people have been obsessed with these cool little mid-engine Porsches for more than half a century.
Fresh oil, proper brakes, good tires, healthy dampers, fresh rubber and tight steering will transform the way the car feels without changing what it is. Once the basics are right, get the alignment sorted, put the roof in the trunk and find a road with some corners.
There will be time for the ultimate engine, five-lug wheels, flares, paint and every other modification you dreamed about before buying the car. First, make it stop. Make it steer. Make it handle.
Then drive it!
