SR240Z Posted May 12, 2008 Share Posted May 12, 2008 We run the walbro GSL392 inline 255 pump on all our sr20 swaps as well as RB swaps. You should be fine with no problem at all. Quote Link to comment Share on other sites More sharing options...

SR240Z Posted May 12, 2008 Share Posted May 12, 2008 No problems at all. We have it running on all cars that are a basically stock swap. Quote Link to comment Share on other sites More sharing options...

c34sr20det Posted February 5, 2009 Share Posted February 5, 2009 Hey my c34 with blacktop s14 sr20det in it was in getting checked out. Mechanic found that my fuel pump was only pumping 18psi nd it was leaning out. It now has 500hp bosch fuel pump. It runs better but hot idle is not good and seems to detinate when only just hitting boost. Ne ideas? Quote Link to comment Share on other sites More sharing options...
Lewis Maudlin Posted February 9, 2009 Share Posted February 9, 2009 you sir, are amazing, thats the exact pump i have sitting on my bench. any problems running it with the stock fpr? I run the same walbro pump. I have no problems running it with the stock fpr. I think most everyone runs a walbro. Quote Link to comment Share on other sites More sharing options...

Which turbo are you using? The stock injectors can't really handle any significant upgrades. The 550cc injectors are barely good to 400 hp. They run at 90%+ duty cycle.

c34sr20det Posted February 12, 2009 Share Posted February 12, 2009 Its got standy T28 ballbearing turbo. Everything basically stock apart from b.o.v, front mount, exhaust and the fuel pump. Think mite have found problem. There is a whole bunch of wires coming off the ecu that go no where. Currently trying to find wiring diagram for 98 silvia jap import. Have only came across 200sx which is nz new version. which has different coloured wires so does not help me. Quote Link to comment Share on other sites More sharing options...
