1958 Judson Supercharged MGA 1500 Roadster
Vehicle Modifications (all easily reversible for the purist)
Gear reduction starter: eliminates “hot starts” and greatly improves performance and reliability. The Hi-Torque starter is equipped with five (5) full roller bearings while the typical Lucas unit uses two (2) bushings to suspend the armature.
Generator to alternator conversion and conversion from six volt positive ground to 12 volt negative ground electrical system: allows power needed to run modern stereo equipment.
Stainless steel long center branch header: provides much better overall performance and adds more torque in low to mid range.
Stereo: a new (April 2015) Kenwood KDC-BT362U CD-receiver, Ipod/Iphone connection via USB/Android via Bluetooth, with remote control. Absolutely no holes were cut to accommodate any of the stereo components. Speakers (six total in the cockpit) are enclosed in custom enclosures resting inside the door map pockets and attached to the exterior of kick panels with screws. All are easily removable without damaging any other original items (although once you hear the stereo you would never consider removing the system!). A small carpeted powered subwoofer box rests unattached in the trunk. Dynamat professional sound dampening material was applied beneath carpets and inside doors to reduce road noise and heat. The combination makes for the greatest tunes ever heard in an MGA.
Electronic Ignition System - Mallory Hyfire Electronic ignition system, Mallory Unilite electronic distributor and electronic coil: no more Lucas ghosts in the electrical system, and this system will throw a spark from Dixon to Davis! Quicker starts, smoother idle, more power, greater reliability and overall performance are just a few of the benefits.
Custom machined cylinder head (courtesy of Mike Singleton of Sports Cars Limited): includes 190,000 psi tensile strength competition head studs and filling of some of the voids in the stock head.
Solid State electronic fuel pump: smoother acceleration
Judson Supercharger and two-barrel Weber downdraft carburetor: a truly wonderful addition to these cars, adding power, torque, and an understated growl. This is a complete and all original Judson package for the MGA including the custom valve cover with the Marvel Mystery oil reservoir and automatic oiler. They do require periodic checking of the integrated Marvel Mystery Oiler to ensure that the reservoir is full, which is easily checked through the sight glass incorporated into the right side of the custom Judson valve cover. The oiler needs periodic adjustment to ensure that one drop of oil is metered into the Supercharger to lubricate the rotating vanes every 3-4 seconds. Some minor exhaust smoke is created during starts due to pooled supercharger lubricant burning off, especially noticeable if the engine has not been started for a few days.
The boost gauge mounted on the dash to the left of the steering wheel is not an original Judson gauge as these are impossible to locate. A replica gauge is now available for approximately $350.00.
Horn: in these days of Supermax SUVs a little MGA roadster is easily overlooked (literally) on the road and the pathetic squeaky original equipment horn is inaudible. I have replaced it with a European-style police siren air horn that is VERY audible!
Sixty-spoke chrome wire wheels: no comparison with the 48-spoke painted silver original equipment wheels that now hang in my garage.
Chrome luggage rack with custom leather straps: with a spare, jack, tool roll, and subwoofer in the trunk this accessory is pretty much a necessity even for a long day trip. Doesn’t look bad either.
The convertible top is in like new condition. I have not driven this vehicle with the top up since I bought it in 2005, and never driven unless it is not raining. I have brand new sliding window style side curtains in my garage, never used, that still have the protective plastic film on them.
This is my fifth MGA, probably my last, and far and away my nicest and most reliable. It is also the same factory color (Island Green) as the first one I owned when I was 18……….hence the license plate.
