This 1990 Jetta is a love letter to the VR6 era — a built 12V head with big valves and ported cams, plus a lightened flywheel, make the motor rev and respond like a race-bred classic. Techtonics’ EPROM OBD1 tune brings the fueling and timing into line, while H&R springs and ST sway bar sharpen chassis control. Samco coolant hoses and other ancillaries keep it reliable. It’s raw, analog and all about that VR6 soundtrack — the kind of car you drive hard and smile the whole time.
