1965 Austin Healey Sprite Build with Turbocharged 1.6L Miata Engine Swap

Ran across this 1965 Austin Healey Sprite build posted on Britishv8.org, using a creative approach to rectify the all too common vintage English car “reliability” issues…it has a turbocharged 1.6 liter Miata engine and 5 speed transmission swapped in place of the standard 1275 cc inline 4. Hey, call it sacrilegious if you want but some of us prefer driving to wrenching all the time. Had to stare at it for a moment to realize what was going on here, as the original front bonnet and fenders have been replaced with a fiberglass “Bugeye” style front end. Digging the British Racing Green, an overall pretty tasteful build that has got to be an absolute hoot to put through the gears.
