Full-Race Geoff Posted November 21, 2006 Share Posted November 21, 2006 Hey Guys -- got a 100% stock R32 in the shop right now. I am building a 3" exhaust and a new fmic setup, bu the customer wants to upgrade the turbos, but stay on the stock fuel system. We dont have too many R33 gtr turbos here, but we do have the 2860R and 2560Rs, which are designed to bolt-on to a GTR. What is the limits of the stock system? Ive been searching, but most everyone ive found runs a powerFC. thanks Link to comment https://www.sau.com.au/forums/topic/144247-limits-of-the-stock-r32-gtr-fuel-system-afc/ Share on other sites More sharing options...
GTRgeoff Posted November 21, 2006 Share Posted November 21, 2006 My GTR33 has 260rwkw on the stock computer with cam gears, adjustable reg, stock airbox, full exhaust, steel wheeled turbos and a bit of head work. That is about the limit of the fuelling system though and it is on full static advance.

Thanks alot for the help Edited November 21, 2006 by Full-Race Geoff Link to comment https://www.sau.com.au/forums/topic/144247-limits-of-the-stock-r32-gtr-fuel-system-afc/#findComment-2692732 Share on other sites More sharing options...
GTRgeoff Posted November 21, 2006 Share Posted November 21, 2006 I do indeed. Car was done before I bought it by RacePace. As for duty cycle, not sure but since new turbos are going in soon I'm installing 600cc injectors, PFC and 044 with swirl pot.

I want to know how much he will charge to fit 12 clutches in my r33 transfer case. thanks Link to comment https://www.sau.com.au/forums/topic/144247-limits-of-the-stock-r32-gtr-fuel-system-afc/#findComment-2696598 Share on other sites More sharing options...
PSI_GTSII Posted November 23, 2006 Share Posted November 23, 2006 My R32 GTR is stock except for a Pair of 2560R's It has the boost restrictor removed and boosts to just under 1 bar. At this boost its only producing (315rwHP) 228rwKW, Factory ECU cannot compensate for the increased airflow from new turbos and AFRs running very rich on as it comes on Boost. I am told the addition of PFC alone will add 40rwHP with no increase in Boost Link to comment https://www.sau.com.au/forums/topic/144247-limits-of-the-stock-r32-gtr-fuel-system-afc/#findComment-2697821 Share on other sites More sharing options...
