At what point?
At what point should I install a fuel pump? I bought an FD with a bad motor in Aug. Since then I have installed a malloy reman, non-seq setup, silicon hoses, boost controller, full 3inch exhaust (no cat), hard pipe intake, koyo radiator, front mount and greddy pulley. I also bought a RX7.com reprogrammed ECU that should cover these mods. On a side note I have never driven this car and havent started it up yet (just finished it). Should I install a fuel pump or will that be over kill? Thanks for any help.

You don't need a higher flowing fuel pump until you've installed larger injectors. The stock pump will outflow the OEM injectors.
Please use the search function next time.

I agree with bricke, lose the remapped, get a PFC, injectors and a pump and tune it.

The ecu will run plenty of fuel until he exceeds the physical limitations of the injectors, which will be at 13-14 psi.

I don't plan on running more then 1bar ever. I also plan on keeping the twins. I'm building it for autox/drift. I know going non-seq hurt me with the low end though, I just really wanted to get rid of the rats nest. When upgrading injectors should I upgrade both primarys and secondarys, or would upgrading my primarys to 850's be enough?

Believe it or not. I ran my t78 off the wastegate(9 to 10psi) on a stock fuel system and a PFC,datalogic and wideband. I ran it for about 6 months before I put my extreme fuel system in.

Also, you are screwed for auto-x running non-seq. Hope your local guys only run fast courses.
