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...

Alfaholics GTAm Twin Spark Cam Cover

Manufactured exclusively for Alfaholics, this cam cover gives a stunning GTAm look to the twin spark engine. CAD drawn and CNC precision machined from a solid billet of aircraft-grade aluminium, the quality is amazing – it has to be seen to be fully appreciated! It can be supplied hard anodised either grey or dark red, or alternatively in a polished aluminium finish. By computer designing this cam cover, we have been able to improve on two particularly poor features of the original GTAm and standard twin spark cam covers. Firstly, we have replaced the often leaky GTA breather filler capMore...

Forged Lightweight Twin Spark Pistons

Beautiful quality with special anti-friction coated skirt, exclusive to Alfaholics. 84.6mm. These pistons are of the very highest quality of design and manufacture and are extremely lightweight. Piston mass reduction is critical to reducing conrod loadings which is very important in these 2.0 Alfa engines which have a long stroke. We can have these made to any diameter if required. Come complete with gudgeon pins, circlips and piston rings. Pistons pocketed to allow use of the latest profile Alfaholics race cams.

Alfaholics Twinspark Race Conrods

Manufactured exclusively for Alfaholics to our own specification, recommended for use on Twinspark engines that regularly use over 7,000rpm. These rods are simply the highest quality parts available on the market, fit the best! These rods feature an I-beam section, which makes them lighter than the typical H-beam design whilst being just as strong. We have manufactured these rods to 2.0 Nord 157mm length as being slightly longer makes the application of the piston force to the crank more efficient. Compatible for use with our own forged twinspark pistons and most other aftermarket pistons.

Alfaholics Thermostat in Housing

Alfaholics production. CNC machined billet aluminium remote thermostat housing for twinspark conversion 105 Series cars. We have manufactured this system to allow us to source a lower temperature thermostat than using the Alfa sourced item typically available. By running a 74 degree thermostat rather than one typically 10-12 degrees hotter results in a 3BHP increase in back to back tests on the rolling road. The cheapest BHP increase to be found!

Alfaholics Full 3-D Mapped Ignition System for Twin Spark

Convert away from original twin distributor or avoid expensive GTA 8-point distributor conversion with this superb mapped ignition kit. This is a full 3-D setup which allows ignition advance to not only be endlessly variable dependant on engine revs, but also with regard to throttle position. As a result the ignition timing can be refined far beyond the wildest dreams of a distributored engine! This results in a far smoother power curve and far greater ability to iron out flat spots. As a result, far more wild ‘race type’ cam profiles can be used on road/trackday engines, than could normally,More...

Alfaholics Throttle Body Injection System for Twinspark

Following the huge success of our 3-D mapped ignition system, we have introduced this new system for full fuel injection control. It uses a pair of high quality throttle bodies combined with air temperature, coolant temperature, throttle position and exhaust lambda sensors to control both fuelling and ignition.  We have carefully selected injectors which are rated to 250BHP in a 4 cylinder application to ensure that the injector flow rate is optimised for Twinspark application. Many ‘off the shelf’ injectors are rated to 185BHP which is inadequate, whilst the common ‘next size up’ injector is rated to over 300BHP, which causes poorMore...
