Alfaholics can rebuild and tune 2.0 Twin Spark engines for trackday or race usage. Engines can be built as either complete first series 75 engines, or with the option to have a second series (cleaner looking) 155 head. Whether you want injection or carburettors, distributor or mapped ignition we have a solution for your needs! Performance options ranging from 190-220BHP. Please e-mail or call Max @ Alfaholics for details on specification & options. Latest development for 2010 with 155 Twinspark Head. For this customer we needed to build an engine running with only 4 plugs and single distributor to meet his race regulation (more) Please not that we are not able to supply donor engines so you will need to provide a rebuildable core engine.

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! Supplied as standard in crackle black or by special order with a hard anodised finish in 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 cap with a CNC machined cap, utilising a rubber o-ring seal and threaded fitment. This also provides a high quality feel to fitting and removal of the cap. Secondly, the cam cover has been machined to accept a rubber o-ring seal (supplied) to replace the notoriously leaky paper twin spark cam cover gasket - spark plug holes filling with oil are a thing of the past! This work of art can be supplied in both 75 (with distributor cutout) and 155 (no cut out) versions.

Completed CNC machined from billet aircraft grade aluminium and anodized. Designed to bolt to either the front or rear 2 bolt flange on the exhaust cam side of all 75 and 164 TS heads. This is the same part as we use in our billet cam cover kits to give a neat and high quality breather take off without having to run a breather pipe right round from the inlet side on a standard cam cover. This unit features a fully rotating outlet with rubber o-rings to seal the 2 components and a CNC machined offset trap door in the neck to minimise oil consumption.

We have developed our own range of camshafts using the very latest computer modelling. We have a range of 2 profiles to choose from depending on your application - ranging from road through to full race use. These cams give better power, torque and driveability than C&B cams and are machined from solid steel billet and rifle drilled for weight saving. Please call for information.

New Alfaholics production. In designing this crank, we started from scratch using current knowledge and CAD to produce the optimum crank for the Alfa 2000 Nord and Twin Spark engine. It features a special oil gallery design that improves flow to the bearings at high revs and has the webs shaped for optimum counterweighting to the piston & rod at high revs, something which is not very good with the original Alfa crank. Furthermore, the big ends are specially bored hollow to further reduce centrifugal weight. We stretched the stroke to the maximum possible, whilst ensuring that the crank fits the block without...

New Alfaholics production, developed for our new Alfaholics GTA-R 290! The inlet manifold has been CNC machined from billet aircraft grade aluminium and anodized. This manufacturing process has allowed us to be able to reduce material thicknesses resulting in significant weight saving over a traditional cast inlet manifold, whilst simultaneously giving an amazing appearance and surface finish. The individual throttle bodies are bespoke, and feature lightweight trumpets and a billet CNC machined fuel rail. This full assembly represents an amazing 1.5KG weight saving over an equivalent cast manifold with traditional throttle bodies. The inlet manifold features 2 heater outlet ports, an M12 boss for an ECU water temperature sender and a bracket for attaching an original Alfa throttle quadrant.

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...

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 poor...

Alfaholics production, stunning quality. All components are fully 3D CAD drawn & CNC machined from billet, providing outstanding accuracy of components and quality control. The external body design follows the nicer early Marelli S119 1600 GTA distributor with vertical mounted condensors, while featuring the internal design and shaft dimensions of the later and Exclusive Alfaholics production, CNC machined housing mounted with 2x USB programmable 123 ignition modules to drive 2 coils. Supplied complete with 8 point cap & rotor. This unit can be used on 75/164 based twinspark conversions to give an authentic GTA look to the ignition system, or can be used on genuine GTAs looking for an improved ignition system but will require the GTA oil pump being converted to a normal peg.

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!
