The Replacement for Displacement: An Ode to the RB26DETT

The RB26DETT is legendary in the tuner world. It’s no wonder this 2.6L inline-6 has been swapped into everything from Fords to Ladas. The 24 valves, six individual throttle bodies and parallel twin turbo system all made it unique compared to previous RB engines. What made it extraordinary was the cast iron block. Capable of withstanding diamond-producing pressures, this meager 6-banger could produce as much as 1,300 hp with extreme modification. That’s 500 hp per liter. Five-hundred! I’ll let that sink in for a minute.

It’s hard to imagine any engine pushing over 600 hp without the semiannual grenade going off under your hood, but the RB was surprisingly reliable. It was also highly valued in the drifting world where low weight and high power are essential. Crate motors are still available anywhere from $3,500 to $13,000 for the N1 brand new with shipping. Hmmm, I wonder how that would look under my hood.

What say you, RideLusters? What would you drop this bad boy into? Assuming you didn’t have a hollowed out R34 on blocks, of course. Also, any other favorite engines out there?

    Dude is saying that 600HP+ tends to result in engines imploding twice annually, which sounds fair to me. I know it’s true for the Ford 4.6 at least.

    I really, really appreciate writeups of individual engines like this. It helps me understand what makes different engines great. In my mind, 2.6 liters equals delicate baby engine, yet at the same time, i know that this 2.6 is a beast, but I just don’t get how. While I’m sure six individual throttle bodies aren’t the only cause of why it’s so bonerific, but it’s definitely an indicator.
