Cause i've had a few people asking me this... figured i would make a thread on it... that way i can be lazy and just link people to it... 2 years ago i knew f*ck all about cars and mods and stuff, so i'll try and write this in a way that even mechanically illiterate me could under stand
note: unless there is an "official" australian distributor for these parts, im not going to link you to a specific company, but will put down the company who sells them in the "can buy from:" area
I'll break it down into a three sections:
- What pump to get/Where to get it?
- Why/when do i need one?
- How do I install it/Who do i get to install it?
- Why do they "fail"?
What pump to get/Where to get it:
ok, you want a new/better fuel pump, now which do you get?
there is 2 sorts, a full pump replacement, or just replacing the internals
FULL REPLACEMENT:
CPE high pressure fuel pump | MPS Garage
It costs a bit, and you either have to send your stocker back, or pay an extra $500.
OFFICIALLY, it's only available through MPS Garage...
(why is it the best? because it's made of crushed unicorn horns...)
Mazda DISI Complete High Pressure Fuel Pump | HPFPUpgrade.com
Comes in 2 "stages" depending on how hard you want to push your car
Once again, have to return your stock fuel pump, or pay an extra $350.
HPFP INTERNALS:
note with these, when you get the internals, quite often it will say it's for a VW/Audi, this is fine, our pumps are the same, assuming you dont just blindly buy a set of internals, but ones under a MPS/mazdaspeed section of a store, you will be fine.
AutoTech
ok, after much reading through MSF, these seem to be the "flavour of the month" atm no reported failures, and they are supporting people pushing in excess of 450hp (340kw) at the wheels
can buy from: edgeautosports
KMD
these seem to be second choice on MSF, there was one bad batch that went out, but apart from that they're holding pretty well... the first MS3 to crack 500whp was running these. KMD is working on a fuel pump to support 600+ whp
can buy from: KMDtuning
PTP
ok, PTP seems to be the 3rd choice... few issues have happened... but mostly it's pretty good
can buy from: ProtegeGarage, PT-Performance.com
Carpe Diem Fuel Pump Upgrade
ok, im not going to suggest these to anyone, based on the simple fact that this company is no longer in business
Carpe Diem Fuel Pump Upgrade | MPS Garage
TRZ
once again offered by MPSG, cant find anything except this:
tzr fuel pump internals - anyone heard of these? - Mazdaspeed Forums
once again, not going to suggest these...
Why/When do I need one:
MSF will say "anything more than an intake, get an upgraded fuel pump" i will say something similar...
if you're doing anything more than an intake, make sure you log your fuel pressure (dashhawk/torque for android/etc), and as soon as it starts to drop below about 1600psi (11,000KPA) during a 3rd or 4th gear full throttle run from 2500 to 6000rpm, get one...
it'll be pretty dramatic if it happens, you'll see your fuel pressure suddenly drop to like 600-700psi (4000-5000KPA) for a decent chunk of rpm's
you need a proper functioning fuel pump to stop your car blowing up...
please dont fill this thread up with "i have x/y/z mods, do i need a FP?" LOG YOUR FUEL PRESSURE and if it's struggling, upgrade your pump...
How do I Install/Who do i get to install:
short answer, i dont know how to install them, im not a mechanic, i got a friend to do it...
if you (like me) are mechanically inept and cant do it, get a trusted friend, or local mechanic... in theory it shouldnt take more than 2 hours...
Mitch has typed out a how to in this thread: LINK
if anyone feels the need to add more to this, let me know and i'll update it...
Cheers from your mechanically inept forum dweller
