Alfaholics Super Sleeve

We have developed this special liner system in order to prevent the notorious head gasket failures usually encountered when running a conventional Autodelta style monosleeve liner. The problems associated with these Autodelta liners are brought about by a reduction in structural stiffness as a consequence of the base of the block having to be machined away extensively to fit this type of sleeve. Traditionally, it had been necessary to use a monosleeve in certain instances, i.e. when running a 1750 block with 84.5mm bore (for 2000 GTAm application) and also in Nord & Twin Spark engines in order to runMore...

Heavy Duty Engine Mount – Left

105 series cars have always suffered from engine mounts that are too soft for competition use, which causes the engine to move far too much under cornering.

Re-built Bosch distributor with re-mapped advance curve

We can rebuild your current Bosch or Marelli distributor with a remapped and optimised advance curve. The distributors fitted to Alfa Romeo 105 Series cars have proved to be unsuitable for use with modern fuels because the original advance curves set were designed for the old 4 star leaded fuel which has a different burn rate to that of modern fuels and was inherently less prone to detonation. As a result, compromises need to be made to the timing and this usually takes the form of reducing the maximum advance at speed in order to avoid dangerous detonation. However, this results in an unfavourable reduction of the idle setting, whichMore...
