    Default 1998 Birkin S3, well sorted and major updates

    Yellow Birkin S3 built in 1998, $25k obo, constantly updated, well sorted, easy to drive, RELIABLE, 2 liter Zetec, T9 5 speed transmission.

    Odometer now shows 64xx miles, it had 2164 when I took delivery on July 5th 2014. With slipping clutch (as described by previous owner), excessive rake and shocks set to maximum stiffness, I can see why nobody drove it much! With the clutch slave cylinder bled, rear shock pre-load and damping reduced it now rides comfortably and handles magnificently. Firmware update for ECU and tuning made the engine start instantly and run strong. Cold air intake brought more top end power and smoother running yet. Front facing intake rig now installed, rear facing rig included.
    Raceline water rail, Stewart Manufacturing electric water pump and controller, electric fan, East Coast Alternator 6 pound 2025 UltraMini 55 amp installed 2018. 2 Ford reprogrammed ECUs, 2 PCM and ignition modules included. Engine believed to be Series 3 because it has aluminum and steel sump, offset water pump, and horizontal oil filter. Fresh Ford plug wires, T9 standard ratio transmission flushed and fresh Redline gear lube 2020

    Easily removable headlights with integral turn signals make aiming easier, includes new and used chrome buckets. Old style front turn signals and fender signals included.
    New, non-tinted windshield 2020 Spare windshield mounts could be used for a polycarbonate, shortened windshield.

    Wilwood .75” brake master cylinders, fender stays, working fenders and new front fenders. The new front end is quick and easy to align (street and track alignments now practical) and improves handling with 2” wider track than original.
