I recommend ALL modded FC3S turbos to get one.

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.

enjoy!

 

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!

 

Thank you. M3s like to do the whole freeway bit where I´m from so it´s a fairly regular occurance. I personally think that M3s are nowhere near what they´re cracked up to be but that´s just me. On a side note, I´m actually in Barcelona at the moment and am traveling to Athens in a week or two, we should meet up so I can check out your rides

 

No problem!

I dont think you are bringing the 7 too uh?

Cause If you do... I can arrange an FC only meeting... about 10 FCs!

 

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

 

I was talking to Nismo Convertable88 earlier in the week. He made 240rwhp on a S5 engine, 3" exhaust, intake, Rtech, 720 secondaries, 10psi.

 

^ thats nice.

Anyone else? HELP!

 

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

I should have seen your topic earlier....Showoff!!!
You should rename the thread to...
The Quest for 300!!!
Good luck.

P.S. the monster is still taking a nap

 

Mori xrepoura, kai na xipnisei to teras 8a to exw mou fainetai... LOL!


Sorry about that!

More opinions plz?

 

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.

 

Common mates, any thoughts about the above? Especially about F-CON?

 

Get a stock LS1 and you are all set.

Andrew

 

^ Thanks mate,

But LS1 are hard to find here at Greece. So...

Any other comments? Plz guys...

 

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.

 

^ Oh man, that suxx.

Is your exhaust system custom made?

At what psi are you?

 

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


-Ted

 

Nobody uses F-CON?
