1989–1994 Nissan Skyline GT-R Fuel System FAQ's

Please read our FAQs page to find out more.

How far can stock injectors and pump go on the R32?

Bolt‑ons are fine; higher boost or ethanol blends require larger injectors and a higher‑flow pump. Many convert side‑feed rails to modern top‑feed for headroom.

Is flex‑fuel worthwhile on an RB26?

Yes—an ethanol content sensor enables dynamic timing and fueling, improving knock resistance and IAT control when mapped correctly.

How do I avoid fuel starvation on long sweepers?

Keep tank levels high for track sessions; baffling or a surge setup helps at higher grip. Log fuel pressure to verify stability.
