if you're on a bargain get a used FD fuel pump or the walbro.
If you have higher expectations out of your car, then maybe a "supra" or cosmo pump. these pumps will flow for more power than you will most likely ever have.
heres teh fuel pump rewire.

anyone have more info on the powerfc in an fc? i had started a thread before but didnt get much info. i know ap engineering has it and all and i have never found one under 1700 yet. ive seen that one japanese site (some diary) where they spliced all the wires themselves and got it to work. anyone successfully do that yet here and have info to write about? i honestly do not want to go with haltek or anything else except the pfc. the other stuff just seems.....older and more of a hassle. also, i dont want it because of the fact that EVERYONE uses it. (just like to4 turbos).

Thanks guys, GREAT info!
limbar85,
here in Greece I have a member of the Greek RX7 Club with an FC3C and a PowerFC. It doent fit right in, it needs somekind of "plug" or "converter". But the car rocks! Right now is working at 0,5bar. Its kinda low. The problem that we have encountered is that at 0,7bar or 0,9bar that we tried to work the car, something weird happens: The car "stalls" like when you hit the Stock Fuel Cut. Any ideas? Any suggestions?
I am asking, since I am gonna try PowerFC replacing stock ECU.
Ted,
thanks mate! BTW my battery is in great contition (new). I will check the altenator ASAP.
dag,
Nice car dude! Spanked an M3? wooow...
Node,
Nice info, thanks!

Haha, not likely unless I magically get it shipped from the States in a week. I´ll PM you or something when I figure out my exact plans and when i´I´ll be in your neck of the woods, alright?

yea...i had thought about doin the pfc thing but decided i would prob end up with more of a problem. the "plug" your talking about might be the connection for the manifold pressure sensor, because you would be getting rid of the MAFS, or it might even be the whole ignitor ordeal. i found that site i was talking about. http://homepage2.nifty.com/fc3s_dragger/diary.htm#. its all japanese but im sure u could find some translator (i tried to get my mom too do it cause shes japanese but the terms and all confused her). it shows plenty of stuff that im sure you could get by with. my plan when i was going to do it was to use this wire adapter so i wouldnt have to splice into the main harness. http://www.rx7.com/store/rx7/fcecu.html. its at the very bottom of the page. all ideas for me now. itll happen when i get older (only 15 now....haha)

dag,
ok mate! We will talk Uh, I warn you though my english are bad as hell but I will have a translator along... with an FD3S! hhehe
limbar85,
Do be ownest, I dont know much about PowerFC. But a friend of mine and mechanic knows it very well. He has used it at least once on FC and many many times on FD. I hope he will "fix me".
Anyone know about the "fuel cut" thingy with PowerFC that I mention above?
Thanks guys!

powerfc is a plug and play standalone.
It plugs into your engine harness like your stock ecu would. but you can change pretty much EVERYTHING
It's a very good computer for plug and play.
It does NOT have a fuel cut, that is the stock computer
There is a Power FC Forum here. Try to find it. Very useful.
Apexi only makes Power FC for FD, but there are several tuning companies like Border and FEED that make harnesses and adaptors to make them fit series 5 FC's. 89+

Ok guys, here is where I stand right now:
I have:
-Removed the air pump.
-Removed the pre catalyt- use of 2.5in downpipe from RB.
-Removal of the stock catalyt- use of hi flow "racing" catalyt.
-Removed of the stock air intake- use cone filter.
-I have "wide" dual "stock look" mufflers.
-Lighter flywheel
-Upgraded clutch
-17in BBS wheels
I measured my boost. Its keeping it steady at 0,5bar and the car rocks! I am now constructing a "ram air" for my air intake. Since now I do NOT have a CAI, my cone filter simply sucks warm air from the engine bay. This is very bad so I am planning a "ram air" setup to give my cone filter some cold air. I know the best setup in this condition is the "hole" above the headlight, but I dont want to spoil the stock look at my convertible.
I post fotos ASAP.
Here is a foto of my baby.

Finally an update.
-I have used some nice Magnecor wires.
-I have somekinda of Ram Air into my car
-Double altenator pulley by Knight Sports.
-I hope by this week my TID and CAI will be ready.
Now I want more power. I have 7.2psi pressure. With the TID and CAI I am sure its gonna play at 8.7psi.
First question: How much power I am getting with 7.2psi? With 8.7psi? Anyone can estimate? The motor has good compression.
I have a friend here at Athens, Greece. He loves RX7s and has good knowledge of them. He is telling me to try this setup:
-HKS F-CON
-FD fuel pump
-GReddy Profec B
-GReddy Blow off valve type S
He suggests to try at 13psi. Of course we will check the AFR ratios in order to be safe. I am wondering: How much power will I get at 13psi? I am asking this, cause I want to know if it worths the money or not.
I am thinking to use the whole setup at 11.7psi just to be more secure. Anyone can estimate what the BHP will be at 11.7psi?
More info about the car:
-Removed the air pump.
-Removed the pre catalyt- use of 2.5in downpipe from RB.
-Removal of the stock catalyt- use of hi flow "racing" catalyt.
-Removed of the stock air intake- use cone filter.
-I have "wide" dual "stock look" mufflers.
-Lighter flywheel
-Upgraded clutch
-17in BBS wheels
-Blistein shocks

here are some rough approximations. Of course, I'm not sure if your mods match with what RETed recomends here.

Yo! Help!
Any opinions about F-CON etc that I mention 5 posts above?
ALSO...
I am thinking of getting a set of R-Magic underdrive pulleys. What BHP gains will I have?
And...: Can I use the pulleys set exept the altenator pulley? I want to use the Knight Sports double pulley and the R-Magic underdrive pulleys.

300 Hp
Just for a rough idea, i have a 3" full exhaust system, microtech proffesionally tuned, rebuilt street ported engine, and a walboro fuel pump. Last week i barely pushed 196hp at the wheels.

You should've been EASILY over 200hp, unless we're talking about a DynoPak or Dyno Dynamics dyno?
