Upgrading FD Fuel system - Questions
So I picked up my first ever rotary and couldn't be happier. It needs a bunch of work and while I wait on parts I'm piecing together what I want to do for the fuel system.
The car how I picked it up is:
full streetport motor with R/A apex seals.
to4 superV trim b-compressor housing and a .96 t4 divided hotside.
50mm synapse WG with street recuirc
Megan manifold
hks front mount
koyo aluminum rad
p/s delete
aircond delete
act SS/HD clutch
blitz street power exhaust full 3 "
car runs with a factory chipped computor
factory 550/850 injectors
So first thing I did was looked at getting rid of the chipped computer and figured I should do the fuel system at the same time. I realize its a fairly small turbo for the RX7 but from the maps I figure I can still push ~350-375hp out of it.
As for the fuel system I'm looking for advice:
I'm planning 550/1680 injectors, stock primary rail and a top feed secondary rail. I don't know off hand what FPR it has, and I'd imagine the fuel lines are original and 20 years old. The pump I think is a Walboro 255 but i need to double check and confirm that.
If I'm doing 550/1680's, should I replace the fuel lines or is that pointless? What FPR would you guys recommend and do you think the 255 pump is adequate, I've read mixed feelings and the general consensus is go with the bosch 044 but is this necessary? I also need to pick up a FP gauge, are some better than others or is it mostly just preference of brands / gauge faces?
