2000 nb1. Have an mp62 and soon to be tvs900 hotside. Straight to the point my goal is to end up to 240hp and I want to confirm that I won't need any other fuel upgrades using 1000cc FIC injectors. I should not need a bigger fuel pump or anything else related to fueling correct? Yes the 1000cc are big for my goal but I chose these from reviews saying they are second best to id1050x for idle tuning. Help is appreciated thank you much.

 

Anyone?

 

I would up grade to a 200lph pump. SuperMiata has a Deatswerks dw200 pump.

 

I have a 240whp rotrex’d NB1. Stock everything fuel related other than FF640s and a DW200 fuel pump.
I put the DW200 in purely for safety, not sure it’s actually needed at 240whp. It was a simple drop in replacement for the std pump so I’d rather spend the 20mins to put on and not need it than the opposite.

 

FF640s and DW200 here, running 240 hp. No complaints, both bought from Nigel.

 

Stock fuel pump is good past 250 wheel hp (if you stay at stock pressure) if memory serves

 

So the conclusion is I'll be fine with just changing my fuel pump with a denso stock equivalent and 1000cc fic injectors? I may switch to e85 so if that happens I'll just upgrade then but from what I'm told is for my power goals 250hp I don't need a bigger pump and the injectors will do the job.

 

I made enough to vent a block on the stock fuel pump with only flowforce 640cc injectors on my '99. You'll be fine on pump gas, but if you're considering E85 you'll probably want something a tad bigger.
