Short tale of a long run

I

GP's mechanical career began in the early seventies. Was mid eighties when he became a dedicated Porsche mechanic. Looking back, and by most professional standards, that's a long run... and it continues. The vast Porsche mechanical knowledge-base GP has encompasses both street and racing. Learn about GP's Porsche credentials here:  GP Credentials

Porsche 4-speed transmission from model 930 is apart allowing gears, sliders, dog teeth, and syncro rings to be inspected
New Porsche syncro ring at left is rough compared to old at right that is worn smooth
New and old Porsche transmision dog teeth compared to each other

Porsche transmission is opened to inspect gears, sliders, dog-teeth and syncro rings for wear. Worn syncro rings and 2nd gear dog teeth are reason this transmission is being serviced. Center: Compare new, rough syncro ring on left to worn-smooth ring next to it on right. Far right: New dog teeth on left compared to removed part on right. Once this transmission is installed, with new syncro rings and 2nd gear dog teeth, my customer will find it shifting like new.

Broken head studs are marked in yellow. There are 2 on this side of engine and 2 on other side. All existing, old studs will be removed from engine case and new ARP studs installed. ARPs will last indefinitely.

Top: Relatively new Porsche with suspension bushing issues made for very poor handling. New bushings return handling to optimal.

Bottom: Customer's lowered '74 Carrera driven from Miami to and through the Rockies. While this depth of lowering allows this Porsche to handle as if on rails---which is precisely what the owner likes---for street purposes this makes for a stiff ride. More, with just inches of clearance, driver's eyeballs need to be constantly GLUED to the pavement ahead. This is NOT a setting I'd advise a casual Porsche driver to go for.

GP AutoWerks does not do paint & body work. 

GP supervises this type of work for customers ensuring it being done to Porsche standards. Look at top photo and see what's wrong there before reading on. The body shop was immediately advised it being unacceptable to leave this Porsche's hood and interior open while this car was in any work area of theirs---dust getting into every nook & cranny being the issue. (This is customer chosen body  shop.) I required this shop to plastic-seal this car's openings and, in the end, clean both frunk and interior of the car to the like-new condition it was in prior to it arriving for refinishing. After this Targa left P&B, it came to GP AutoWerks where final adjustments to hood and door positioning were made.

Porsche Engine & Transmission Rebuild

The Porsche flat format engine---boxer type engine---is unique among car engine's based on two main factors. First, the pistons are horizontally opposed. In affect, one side of pistons is said to be “boxing” the other side (given the pistons moving directly against each other.) Secondly, early model Porsche's were unique on the basis of being air cooled. This distinction arose from Ferdinand Porsche's original weight reduction interests and simplified manufacturing requirements for the initial Porsche racing car... series 356. In 1998, the last of Porsche's air cooled engine-cars were made. The company has since moved from air to water cooling. The last car Porsche produced with air cooling was supposedly purchased by Mr. Jerry Seinfeld.

      While other auto makers crafted engines, transmissions, and chassis for the sake of retail sales, Porsche's beginnings were race-oriented. On this basis, their engines & transmissions were, from the outset, designed and made to be light-weight, powerful, and durable. The focus being to compete and most importantly... win. The first iteration of Ferdinand Porsche's vision was the model 356. To this day, a few of these original 1950 circa Porsches remain on the road. 

 

GP AutoWerks offers comprehensive Porsche engine & transmission service, repair & rebuild capabilities. From the simplest tuning of your Porsche's fuel air mixture, oil and filter changing, spark plug replacement, ignition wire replacement, valve adjustment, to checking cylinder sealing efficiency via compression and/or leak-down tests (and from that being able to advise you if the rings, intake or exhaust valves are leaking for any given cylinder), to the complete factory-standard (or better) rebuild of your Porsche engine & transmission... GP can expertly address any need you have in this area. 305-588-0874

Porsche Brakes & Suspension

Much of the Porsche experience is about how a Porsche handles. And not to be critical of front engine Porsches, it's the original positioning of the engine and transmission to the car's rear that is at the root of why a Porsche feels & handles---for the most part---as it does. Of course there's much more to consider: geometry, weights & distribution, aerodynamics, suspension, ride height and tires. These are just a few of the ingredients that comprise what creates the handling experience of a rear engine Porsche. On a performance scale, Porsche ranks among the top handling cars ever. This is not coincidence. It comes from Porsche's dedication---from the very beginning: to race... and win.

What do You want in terms of handling from your Porsche? If you're not sure, talk to GP. He'll help you answer this interesting question. If you know, he can help you understand your Porsche's current status and what's required in order to achieve the handling you want---be it for street or race track. 305-588-0874  To Porsche Brakes & Suspension / Handling page

Porsche Body Works

Porsche body design is like no other---the 911 form being classic. And to think, Porsche once considered replacing the 911-type in their product line with the 928. This decision was based on Porsche's thinking at the time that, with the introduction of the 930, nothing more could be done with the 911 platform. Corporate leadership subsequently changed at Porsche. And so to did the future of the 911 platform---it continued and has become the iconic body symbol of Porsche. An icon among sports cars.

 

Correcting body damage from accidents or otherwise is NOT what GP AutoWerks does. The role the shop plays in regard to Porsche body work is two-fold: First, GP serves as a consultant answering questions as to what mechanical damage may have occurred from an accident---body shops should not be relied upon to diagnose Porsche mechanical issues unless they have prior proven Porsche experience. Of course GP offers the capability to repair any mechanical damage and will co-ordinate my shop's work with whatever body shop you choose to work with. Secondly, GP AutoWerks is experienced in the alterations that you may want to make to your Porsche's body. Flares, spoilers/wings, etc. Body alterations for the sake of either aesthetics and/or performance driving. Within reason, nothing is impossible with your Porsche. It's a matter of creativity, expert engineering and build-ability that you'll find at GP AutoWerks. 305-588-0874.  To Porsche Body Werks page.

Porsche Interior: Air Conditioning, Seating, Headliner

A Porsche interior is one of the finest in the market for a sports car of its' class. Everything is ergonomically designed with today's Porsche interiors keeping pace with features found in most luxury sedans.

Your Porsche's interior, in Miami the hottest topic is air conditioning. More to the point, AC that delivers cold air from the vents. You'll find a good deal of AC information in the Interior page.

       If your interior is worn, or not to your liking either aesthetically or in regards to some ergonomic consideration, GP can help sort that out for you. Bear in mind, GP AutoWerks does not do reupholstering. GP's role---when called for---is to disassemble parts for reupholstering... supervise the reupholstering work if needed/wanted... then reassemble interior parts. Doing so, you're interior is completed both aesthetically and mechanically as it should be. 

        Perhaps a simple interior-related adjustment is all your Porsche needs. Or, an interior part needs repair or replacement. Whatever the case, GP knows your Porsche inside & out. 

         If You have physical considerations that require specific interior adjustments be made to your Porsche for personal comfort, GP AutoWerks can help you. This concerns interior adjustments that are beyond the scope of the adjust-ability built into your Porsche's controls. Such adjustments may include but not be limited to seat position, seat form, steering column positioning, shifter positioning, seat belts/harnesses, and roll cage structures. To what degree these areas of your Porsche's interior can be modified requires discussion. Call for a consultation.  To Porsche Interior page

Porsche Modification & Restoration

 

When this website refers to Porsche modification, that refers to alterations from a car's stock configuration to non-stock. This can be be for performance and/or aesthetic reasons. In this realm, GP creates and makes changes according to customer-inspired ideas of all sorts. If you have a vision you want to see come to life on or in your Porsche, let's see it! If you want GP to come up with the idea(s) for you..... can do.

       Restoration is just that, restoring a Porsche to some level of its original form and condition. This may encompass part or all of a car. The work GP does in regard to restoration is specifically guided by customer interests in what is to be accomplished, the desired timeline, and what will be invested. To this end, all is defined in advance to all are on the same page before any work begins.  To Porsche Modification & Restoration page

Porsche PPI

PPI is the acronym for Pre-Purchase Inspection. It refers to the professional inspection made of a given Porsche for the purpose of knowing what condition the inspected car stands in. And so, what costs may be anticipated to eventually achieve the condition level a potential buyer wants. Bottom line: PPI enables a Porsche buyer to make an informed decision concerning the potential purchase of a pre-owned Porsche.
