I have a couple simple questions, well simple if you know the answer at least. I have put enough mods on my car I need to remap the pfc. I have intakes, dp, high flow, n1 duals, and the pfc of course. I'm putting in a new fuel pump and intercooler within the next two weeks. I think its about time to upgrade the fuel system itself. So my first question is, what's the better option of a fuel kit out there? The extreme kit from rx7store looks great, but I'm honestly unaware of any other systems available. I do plan on going single in the future which is another thing to think about. I do know I want the 1600 injectors. My next question is, I'm getting jason to remap my pfc with my current mods plus the fuel pump and pettit smic upgrade. In the future, when I put the new fuel kit in, will it have to be completley re-mapped or do I just change the settings for the injector size on the pfc commander? I typed all this from my blackberry so help would be awesome. Lol

 

you should really remap with the larger injectors installed. The transition points will need work and while the injector change in the pfc should get it close I wouldn't count on it being enough. ideally you should get them now and only tune once. the rx7 store kits, and kits from Keith are both good. Stock primaries, aftermarket secondary rail, 1680's and aftermarket FPR would be a good way to go.

 

Get the CJ Motorsport fuel system it looks really good

 

for your modification level you're probably fine with stock injectors and a rewired fuel pump if your boost is under control, check your injector duty cycles

 

My air flow mods include: a street ported motor, 99 twins, open intake, downpipe, high flow cat, RB exhaust, IC, efini y pipe

My fuel system mods include: upgraded fuel pump, enlarged secondaries to 1300cc, stock primary injectors and stock everything else.

I use the PFC also. Car was tuned to 350 RWHP at one point and there was more than enough fuel. Unless you have money to blow, the 1600s are overkill.

 

Except he said he's going single turbo in the near future. course he could always wait to upgrade the fuel when he does go single.

 

^Exactly what I was thinking^
