FMU install

[imported_Becker3ww]

Im currently installing a Garrett Turbo into my 99 Si. Im working on the Fuel Managment Unit,..I have a Vortech 12:1 FMU. How exactly do you put this in? And another question...Do I need a new Fuel pump? If im running at most 10 - 15 psi, will I need a higher performance fuel pump?

The FMU is very simple to install (its basically a fuel pressure regulator) Just put the fuel line in, vaccum line out, bam...your done. But dont do it if your not sure, Take it to an experienced mechanic.

I dunno about the fuel pump, If It were me, yes I would upgrade to like a 255 Walboro Fuel Pump. Very inexpensive.

You need to tap into a certain vaccume line, I had a turbo kit with a Paxton unit,but it was on an H23a, so I dont think I could tell you exactly. also, the relation and location is between where your secondary fuel pump is, then your fmu tap is, then fuel rail is, is not really critical, just in that order.

also, walboro fuel pumps are known for failing when you need them most, ask sr20det owners about them and they'll tell you horror stories. I used a Nos fuel pump, expensive but it was good quality.....always remember quality and you get what you pay for.
