The Nissan KA24DE makes a great turbo engine, but you can also build an NA engine with a lot of torque that is fun to drive!

Loved watching this! I built my NA KA back in 2005 to the best of my abilities and budget when I was a student at WyoTech. Unfortunately, I have yet to really see it perform as I ran out of money for the project, then adult life/responsibilities got in the way. I still have the car, and it is still in the same state as when I left it.
I did a bunch of deburring and smoothing/grinding of many stock components (block, crank, rods), upgraded to Supertech 10.5:1 compression pistons (JE had nothing for NA builds on the market yet), completely balanced the rotating assembly, had a friend from class work over the head (port match, polish, 3 angle valve job). Due to funds it remained(s) on the stock cams and stock computer, so when it got its chance on the dyno it made stock power to the wheels. It ran so rich down low that I had to use my foot to keep it idling, then it cut fuel completely at only 6k rpm. The torque curve was a flat line at 136wtq from zero rpm to fuel cut. For that little bit in the middle, it felt fast as can be with no effort or strain. Always made me wonder what it will do with at minimum an old school air/fuel controller, and then again with proper JWT cams.
Seeing the S13 content and now this is giving me some hope and inspiration to get back into the project in a few years when my kids are a little older. I have plans to make the switch to coil on plug ignition and swap out to a DBW throttle body, then run it off of a standalone ECU.
Technology has moved wayyyy forward.
Any stand alone ECU even the least expensive are amazing.
