TUNING THE NISSAN RB26DETT (R32)

This perfect example of a Nissan RB26DETT R32 GTR returned to FC Tuning for fuel system upgrades. The additions included an in-tank Aeromotive pump and a Bosch 044 inline pump. A set of ID1000 injectors were fitted to a top-feed GReddy fuel rail with twin entry.

This was the first Nistuned R32 in the UK running ID1000s that we had the pleasure of setting up. Even at a modest 3.5 bar fuel pressure, maximum injector duty cycles were at a comfortable 58 percent. That leaves plenty of headroom for more boost with larger turbines in the future.

The rock-solid idle, excellent cold start, and precise fuelling are all delivered by the factory OEM ECU running a Nistune ECU solution. With the engine still stock, we held boost to 1.6 bar peak from the GT2510 turbos. The RB26DETT delivered great power with strong spool-up and excellent response on the road.

Peak torque arrives early and spreads right through the rev range. This is one of the best R32 GTRs we have ever driven. It is solid, smooth, responsive, and rattlefree. The owner was generous enough to leave the car with us for two to three days, which allowed us to give it that extra level of care and attention.

The suspension and drive are wonderful. The exhaust note is tasteful enough for daily use without overwhelming conversation on the way. A real pleasure to drive — and it just wants to boost. When it does, it pulls and pulls given enough road. Enjoy it, and let us get it on track to really exploit it.
