I am planning on getting a rb downpipe/presilencer and maybe an apexi intake for my 90 TII and wanted to know if adding a fd fuel pump would be enough, fuel wise. Would I still need a fcd and/ or bigger secondaries, or should the fd fuel pump be sufficient.

I would really like to know the answer to this question too, since I have a FD pump installed, I have never seen lean on my a/f always rich as ****...............

 

My standard fuel pump was good for about 100-120rwKw before it started to not supply enough fuel.

Forget about the FCD - they are a poor substitute for a proper Engine Management system.

 

So what is the proper set up with DP, intake, catback, and FCD. I ordered an FD fuel pump thinking that it would help with detonation. Don't want to blow this engine with only 68k. Should I install the fuel pump?, remove the FCD. $$ is limited, so what should I do to get the speed safely?.

 

You'll need an FCD.&nbsp The FCD works fine up to 10-12psi.&nbsp The FD fuel pump gives you about 10%-20% more capacity over the stock FC turbo fuel pump - this should support up to about 300bhp; the stock FC turbo fuel pump can support up to about 250bhp.&nbsp Keep in mind the voltage drop through stock electrical:

So it sounds like I should be fine with the fd fuel pump, as long as i make sure it is getting enough current.
Thanks guys

 

Make sure you have a fcd too. And look out for boost creep. Hope you have all the proper gauges to monitor it as well.

 

OK, i guess i will have to get the fcd also. I just installed boost and a/f ratio gauges.

 

Well if you don't get a fcd all the things you get to add more fuel will be useless after 8psi or whatever the fuel cutoff is. It is only $100 and is the easiest thing to install.

 

Thanks Ryde _Or_Die, i will order a fcd along with the other mods. Do some work better than others or do they all work the same. I will problably just order the rb fcd since that is where i will be getting the dp/presilencer.
