Well the issue of Classic Porsche Magazine with the article on John Gregory and Spyder Automobiles is out!
However we in Australia need to wait a bit longer, Issue number 55 is the one, I have been told from a friend in the USA who has his copy, that Richard did a great job writing it! I saw the draft copy and now I am very keen to see the final version!

With some minor adjustment this will be a very well balanced little car the pic shows how it came to us and without driver!

Looking closely at pic 1 you can see the modified caliper mount that was original to the car.
Pic 2 shows the spacers required to get clearance to the wheel centre as these are 3 piece wheels and have a reduced internal diameter.
Pic 3 shows how neat the the wheel fits over the disc!

Shown here is the original brake components and the replacement components and the small amount of machining to fit the discs on to the hubs!

This Clubman was built by a Porsche owning client but the brakes had never matched the performance of the Nissan SR20 Turbo. We were given the task of fixing that, here is the pictorial story! Our search for a suitable replacement lead me to discover the D2 Racing range of products which includes, brake kits, suspension and wheels all of very high quality and excellent value!

Below is what the car had originally!

1976 Porsche 930 saga
This car came in with a miss and backfire; we had rebuilt the engine in 1997. Since then it had seen very little attention in anyway, to the point where it still had the same fuel and oil filter on it in 2015 when we did a service and other work to it!
The car, presented with a miss and backfiring which the first thing to do usually is check all the K Jetronic system fuel pressures, along with compression and cylinder leakage that completed and finding nothing matching specifications in the fuel system, but the compression etc was to be expected. The main components controlling system pressure went away for repair, on return after fitment to the car improved but soon reverted back to a similar condition. Further investigation, discovered leaks from some of the manifold gaskets so the manifold removed and the gaskets replaced. Then the corrosion in the manifold was found, then repaired with JB Weld. I had used this very successfully in the past for similar problems. This time would prove different though! After running the engine, it was found to be improved but slowly reverted to run rough again! I had driven the car and it would still back fire and on return ran worse still, regardless of adjustments made!
It was accidently discovered the seam on top of the muffler had been blown apart with the ferocity of the back firing so the muffler was replaced and all the exhaust joints checked for leaks! Again, the running was changed but not greatly, the backfiring had improved but not fixed. It was then a test jig was used to pressurise the inlet system to try to find any leaks this showed the throttle body shaft was leaking badly so a new one came from Porsche! No other leaks were evident at that time! Again there was a big improvement but not quite enough, the decision was taken to send the fuel distributer away to be rechecked to make certain there was no damage after the backfiring! The distributer head, had in fact, been damaged and needed repairing again! During this time the inlet manifold was seen to be leaking through pin holes so another manifold was sourced and fitted! This time after reassembly the fuel system, the running of the car was very much better! After quite some hours of running it reverted back to running rough yet again, it was time to recheck the engine leakage and compressions, again all was to be expected!
A new set of spark plugs were fitted as the old ones had fouled due to the poor running also the oil had been overfilled and spewed into the air cleaner causing another set of woes! After draining the oil, 1.5 litres extra discovered to be in the oil tank! Removing this additional oil rectified the issue of the air cleaner covered with oil but nothing else!
The fuel pumps were checked for pressure individually and found the front pump had a large resistance in it, reducing the power to the rear pump also both pumps were not supplying the correct amount of fuel! The flow from the tank checked, and inside the tank checked for blockages, all was as expected! Eventually both pumps replaced to restore correct flow and pressure. The wiring also checked and improved!
After multiple times checking and vacuum testing hoses then replacing every hose even if there was no visible need to! The pop off valve was then removed and dismantled and the end gaskets and `O’ rings replaced yet again a substantial improvement was found but after some running and stopping and starting it was not going properly again! The pop off valve came off again and a very inspection showed wear in the bore of the valve after much discussion the pop off valve was, re-sleeved, then, reassembled with clearances as specified! Yet again, there was a temporary improvement! The wastegate was vacuum tested again, this time there was a vacuum leak from it on the manifold side! With the wastegate removed, and dismantled a leak was showing in the diaphragm / membrane and valve guide! So the wastegate had the guide repaired and membrane replaced then vacuum tested before being refitted! No leaks were evident so it was refitted and made sure all joints were sealing correctly and the test run completed, and yet again, a temporary fix was found! With all the work that had been, done it was time to look for the very unusual problems! As a precaution the hoses were both replaced, on the inlet and outlet of the turbo! At this time, the alignment of the turbo outlet hose was found to be incorrect and by removing the securing bolt and moving the pipe the engine would respond running rough then smooth! After correcting this, the engine ran fine for a full day with no issue. The following day checking for a cold start it was running rough again! While watching it run suddenly it went smooth and stayed that way all day until late in the day when again watching it the engine un-fixed itself! This time the car was really getting to me and thoughts, of an exorcism started to cross my mind!!
This time the engine came out and this allowed a full inspection with all the components assembled as they are in the car! A smoke machine was, eventually made available and used this even initially showed no fault until I started to poke around with a screwdriver. The small exposed flap of one inlet manifold gasket could be almost moved the smallest amount allowing some smoke out! So the inlet manifold was again removed all the gaskets removed and cleaned off it was only then the tiny cracks could be seen in the manifold insulator blocks which seem to have developed as this repair has been under way! The first time the manifold was removed, these cracks were not there, nor was so much distortion of the insulation blocks, such was the force of the backfiring!
With the car reassembled and a new confidence found, the engine ran very happily and required small adjustments the only issue was the first couple of seconds after a cold start, this meant a minor adjustment of the warm up regulator and the car was back to being good as new! Road testing for 200 kms showed only very minor adjustment to be required!
