Nissan GT-R Injector Flow Test Comparison and Future Upgrades

May 31, 2009


More and more injector upgrades are being placed on the market to meet the fuel demands of the more powerful GT-Rs out there. There hasn’t really been much publicized testing or even acknowledgment of the standard injector capabilities versus after market items though. Garage Saurus have made it pretty simple for us with a nice visual you can check out below.

In their testing, the standard GT-R injectors flowed equal to a 570cc injector. You can see below the comparison with SARD 650cc injectors which flowed around 660cc for this test and BOSCH 750cc injectors which actually seemed capable of flowing up to 820cc in testing.

As a side note, Garage Saurus liked the BOSCH injectors so much they will be using them in a big injector bolt-on upgrade for the GT-R which they’ll sell you for 24,000 yen a piece, or 144,000 yen all up. Don’t all rush out and by them though because the GT-R still needs something to control these big injectors. The standard ECU is out of it’s depth with injectors of this size.
