1958 XK 150 roadster (JB)
Major mechanical overhaul


Specification (briefly) for this project is as follows:

This is a nice, presentable XK that we are going to mechanically upgrade from stem to stern. The car will receive uprated Team CJ cooling, ignition, braking, suspension, a Stage One E Type engine, triple SU carbs and a CJ5 five speed transmission. The finished article will be the proverbial wolf in sheep's clothing!



We now have the cylinder head completely rebuilt and installed and have started installing all the other engine bay ancillaries, such as the new Mallory distributor, spin-on oil filter and of course the polished stainless steel headers. We should have the old car back on the road in the next week or so.

Modified cam/tach drive
worked out perfectly
Lifting hooks added for 
Polished valve covers add
the finishing touch
Headers installed
Note new mallory distributor
and modern oil filter
 Rebuilt carbs squeezed into place

Although we are not quite finished with the cylinder head yet, we went ahead and rebuilt the block and installed it in the car, along with your new CJ5 five speed. We have also completed the carb rebuild.

We have been steadily gathering  various new components while we wait for the engine machine work to be completed.....

The first photograph below (scanned from Philip Porter's excellent "Original XK" book) shows how the factory cut away the right hand engine bay sidewall to make room for the triple carbs used on the 'S' models. The next photographs show your car, before and after the same side panel has been removed.

With the front suspension rebuild completed, we have now installed the upgraded brake booster and the new Koni shock absorbers at the rear of the car. We have also received most of the carb parts back from the polishing shop.

Your original suspension was in a terrible state and required a complete rebuild, including new shocks, torsion bars, Poly bushings, upper and lower balljoints, wheel bearings, etc, etc.
