Skyline RB25 engine build

Recommended Posts

Having acquired a goodly stock of Skyline engine bits over the years I suddenly realised that I wouldn't need much more stuff to build a spare engine for my R33 GTS-t. I bought some forged pistons and forged Tomei rods, some new valve springs and I already had some Apexi cams. I also had a suitable Garrett ball bearing turbo and a new HKS cast manifold. I did a basic head refresh with freshly cut seats, 4 new guides and a valve lap. I made a wastegate adaptor for a Tial wastegate I had. Not an exotic build, just a quick nailing together of parts to build a spare motor, but thought some of you might want to see it. Should make about 450 BHP with good torque. Put it together with a spare loom on it, a spare PAS pump and it will have a spare alternator and fan on it, so I can swap it over quickly.
