This Datsun 510 used to have a Pontiac Solstice powertrain which included a 2.4 L LE5 Ecotec inline-four. But since the project started in 2009 the owner has continued to upgrade the two-door. The LE5 was replaced with a 2.4 L LEA Ecotec inline-four capable of running off E85. The engine produces 180 horsepower and 172 lb-ft of torque. The previous five-speed transmission was replaced by a T-56 six-speed manual transmission. Power is delivered to the rear wheels through a built Subaru R180 rear end with 4.44 gears. The owner also upgraded the suspension, brakes, and several other components you can read about in the build thread.

Love the car. Not sure why one would put a gm engine into it when the original L16 is a much better engine capable of more hp. Had a 72 510 2dr triple SSS. we installed an L20 and 5 spd from a 200sx. Had a 73 4dr and installed a L20 and a 280zx 5spd. Both cars were very fast and the triple S coupe was incredible.
Ummm, I’d like to see a streetable L16 that makes 180hp and 172f/lbs. I’d suggest that would be pretty difficult (and expensive) when L20B strokers struggle to make more than 150 reliably. I reckon the ECOtech is a great solution for a 510.
