Nissan Fuel Pumps
The Nissan Skyline fuel pump has held a legendary position as the ultimate upgrade fuel pump for the VR4, reportedly flowing 310 lph at 43 psi. Unfortunately, there are no hard data to support this. Nevertheless, some of the Skyline fuel pumps (R33 stock, and HKS and A'PEXi aftermarket) would make excellent upgrade choices for the 3000GT VR4 and Stealth TT.
From what I have read at various web sites, the R32 Skyline came with a 190 lph pump, and the R33 Skyline had a 195 lph pump. I am not sure about the current R34 model. In the April 2004 issue of Turbo & High-Tech Performance magazine, a stock R33 Skyline GT-R fuel pump was tested to flow 252 lph at 43.5 psi and 13.5 volts.
Both Mines and HKS sell upgrade pumps for the Skyline models that flow "only" about 270 lph. The HKS fuel pump (part number 1407-RN019) was also tested in the April 2004 issue of Turbo & High-Tech Performance magazine and it flowed 268 lph at 43 psi and 13.5 volts. The HKS 1407-RN019 and the R33 Skyline fuel pumps tested in T&HTP look just like the 300ZX Turbo fuel pump pictured below.
A'PEXi sells an upgrade fuel pump for the BNR32 and BNR33 Nissan Skyline GT-R. Max Cooper,
Home Page, published results of flow tests by RC Engineering for the BNR32 upgrade fuel pump (A'PEXi part number 404-A011) at his web site. This pump outflows any other in-tank fuel pump for 3S cars that has been tested (that I am aware of). With a tested flow of about 300 lph (adjusted for the 6.34 density of the test fluid) at 43 psi and 13.5 volts, six injectors up to 720 cc/min can be supported by this pump. In their 2003 online catalog, A'PEXi shows a list price of $499 for this pump and the one for the BNR33 (part number 404-A010). I have seen prices for this pump at internet stores for between $359.20 (
Auto Accessories, Performance Parts, Import Parts, Auto Car Parts) and $410.16 (
