We pushed out 393rwhp from Nick’s R33 RB25 twin turbo Skyline the other day at 17psi. We found that the turbos take a while to come on strong so the rev limiter was increased slightly to 7500rpm to make some headroom for the usable torque/power band.
Check out the video, it’s quite interesting in the flesh as it sounds very similar to the RB26DETT! It’s all in the exhaust manifold design.
RB25DETT Skyline… yep, it’s the 26’s little cousin.
