How to build an Early 911 sport purpose Porsche: 1. Find a great chassis 2. Spend a year or more building it 3. Invest more money than it will be worth when its finished. Or, ou can find one that is done and start enjoying while you customize it to your liking. So often, y friends have gone the route of building their own car and by halfway in, hey always seem to regret it. It’s not just the time and money - it’s the countless problems that are uncovered along the way. That is why I always encourage people to spend a bit more and get a done/sorted car they can start driving today. Sure, here may be a few details they want to change to their liking, ut that is all part of the fun…instead of getting update pictures from your mechanic for 18-24 months.

The most important element of one of these builds is the body/chassis. That is your foundation. It is getting increasingly difficult to find a great starting point. This Porsche, 0558 started life as a early 1970 Karmann built 911 T Coupe. It is believed to have lived its whole life in Southern California. Sometime in the 1990’s it was converted to a DE (driver’s education) car and used at local PCA/POC events. The body has been carefully inspected and there are no signs of any damage or rust. In fact, he body has been nicely strengthened over the years with RSR-style gusseted reinforcements on the front and rear strut/shock mounts as well as a tidy “B-hoop” bar welded in for extra strength. The benefit of this extra chassis stiffening results in very precise handling.

About 7-years ago, he owner decided to retire his 911 from track use and make it more of a fun street car. He hired Ed Palmer of Kundensport (one of the more respected early Porsche restorers in the area) to refinish the car as a street car. The paint/body was stripped and completely repainted in Porsche Viper Green. Steel flares were properly fitted to the fenders. The motor/drivetrain had been completely built about 5-years prior but not many miles were put on it. Highlights of this build include:

3.5L engine from a 3.0 aluminum (930) case

911 S camshafts

Late-style Carrera chain tensioners

46 IDA Italian Weber carbs from a 911R

RSR style muffler with sport headers (no heater)

Aluminum rear trailing arms (modified)

Boge shocks in rear

Bilstein shocks on front with raised spindles

Stock Porsche 930 torsion bars

Real Charlie Bar sway bars front and rear

New Porsche 930 turbo brakes all four corners

Carrera oil cooler

Battery relocation to smuggler box with custom raw fiberglass cover

Italian RSR style perlon buckets with turnbuckle adjusters

Vintage sytle Repa 4-point belts

Gauges restored

Dash, oor tops and rear panels refinished by Tony at Autobahn

RSR style front strut brace

Center-fill fuel tank

Fiberglass bumpers, ood, nd ducktail

Steel turbo flares

New lightweight interior (carpet, eadliner, oor panels)

15x9 and 15x11 Correct RSR Frosted Finish (by Braid)

New Michelin TB15 tires from Coker

The engine dyno results (see pic) resulted in a conservative 292hp and 255 lb ft tq.

Recently, hen the engine was out being serviced and dyno-tested, eakdown and compression tests were performed. The numbers were excellent. Compression was an even 180lbs across all cylinders. The leakdown results (readings off of 100%) were:

1) 2% 2) 2% 3) 2% 4) 4% 5) 4% 6) 6%

It is clear by the recent inspection that this engine is very fresh. Although we do not know the specifics of the 915 gearbox, t feels like the gears might be a bit shorter and it too has possibly been rebuilt. The shifting is very smooth and easy with no grinding or synchro issues.

Once the motor had been checked out, local suspension specialist inspected the setup and did some minor tuning to make this the ideal dual-purpose street/canyon 911.

This Porsche is very crisp and responsive. From the throttle to steering to braking to turning, verything feels sorted, uned and fresh. It would be a delight to drive on some local vintage tours especially since it is created on an early 911 chassis (www.TargaCalifornia.com is right around the corner).

We have an additional set of Fuch wheels (see pics) available for purchase that do fit this car. They are made with real Fuch centers and BBS hoops. They are 10x16 and 11x17 with near new tires and correct spacers.
