Is this normal...

[NC_GHIA]

I have an 1991 EA gl 30th anniversary Falcon


In my engine bay,my drivers hand book it says 3.9 litre EFI engine.

But under the hood is a carborated engine dunno if its a 3.9 or 4.0 or 4.1?

Can any body help...

And I have been told If your car is EFI you have to stick with EFI motors.


just asking...

[NA XR6]

It is a 3.9 CFI engine

[NC_GHIA]

But every were in my owners manual it says EFI I know its CFI I m not completly stupid.

[naughtyfalcon]

if it's cfi it will be a 3.9,,but being a 1991 model it should be mpfi

[Rollin]

CFI = Center Fire Injection.

meaning, all of the injectors are mounted in the same place (ie, in your car, in the throttle body, which while it does look like a carby it's actually not.) It is a throttle body with a couple of big injectors in it.

This differs to MPFI which means "MultiPoint Fuel Injection"

Multipoint cars have one injector per intake runner, mounted close to the head.

[NC_GHIA]

oh ok cool... can I still wak on the 2 barrell stainless 350 carby?

[frost]

yes if you remove the computer i think...

[Rollin]

the computer is still needed to run spark.

putting an actual carburettor on the engine will make it illegal, as it will no longer pass an emissions test.

also, EFI systems run around 30-40psi fuel system pressure, carby cars only run 5-7, so you will probably blow the top of the carby if you connect it up with the factory in tank pump.

Carburettors are nowhere near as good as EFi -look into putting a multipoint manfold onto your engine, it will make more power, be more drivable and use less fuel than if you put a carby on...there are a million threads on it here, and fordmods.com has some instructions as well.

[wodahs]

also if you remove the computer your fuel pump wont run , the computer kicks in your pump for priming befor starting and the starts it when the moter is running

ok wow I have a confusing engine... why me?

Welcome to 1984

It's ok, you're not alone, only every EFI car in the world uses the ECU to control the fuel pump, as well as spark.

[NC_GHIA]

but It has a carby... the injector plugs are on the left of the head... there EFI air input, but there is a carby air injection... but in the engine bay and manual it says EFI... ****** im confused!

[kyro_02]

takes some pics of the engine ??

[dansedgli]

Its not carby!! Take the air filter lid and have a look. No carby

CFI is EFI

Your car does NOT have a carburettor!!!!!!!!! It is CenterFire Electronic Fuel Injection.

It has two large fuel injectors mounted in the throttle body, under the air filter. YES, it LOOKS like it has a carburettor, BUT IT DOES NOT.

[Grechie]

its a centrepoint fuel injection system. i used to have it 3 motors ago LOL, its crap for making power,

[gthofan]

he would be really confused if he had the 3.2 ltr hehehe

[NC_GHIA]

oh thank you
ok can you tell is there any good ways of improving my power... But wont bust the bank...

[gthofan]

first up- extractors, multi point conversion, then k&N filter in the multi point airbox.
extractors- $250
sports exhaust- $250- $300
Air filter- $130
multi point conversion- check with wreckers

[gthofan]

then there is a cheap way, add flames down the panels, racing stripes, oh and paint ur car red

[Jason[98.EL]]

pm sent

[NC_GHIA]

well i have a sports exhaust allready... I got quoted on these extractors that are better then pacemaker(apperntly) but i cant remember the name... but they were $550
I was also going to take the head off clean it shave it and put arias forgged pistons in. get the cams done, put bigger injector leads and plugs in and a K&N pod air filter in... any estimates on the total price of that?? and wat do you think of power upgrade how much more (roughly) would I be putting out(including the extractors)

[NC_GHIA]

thats probally the expensive way.. paint job is $10,000 plus.
and racing strips are $1500 if painted and $500 if they are stickered
and flames I have no clue?

[Rollin]

dude im pretty sure he was joking when hey said that hey...paint doesnt make your car faster...

As gthofan said in the post above that one, the things you should do for more power are:

Convert it to Multipoint Fuel injection (MPFi) either by putting the different intake manifold on your car or putting an entire engine from an EB or ED (or even an AU if you are keen, but they cost a fair bit) then get pacemaker extractors.

after that, get a reground cam from surecam, wade or crow (my personal favorite is surecam) and then start thinking about changing the diff gears or converting to manual (if your car is an auto)

[EDXR6T]

10.000 grand plus for a paint job?? tell him he's dreaming:P

I like the idea of "bigger injector leads", that sounds like a top mod
go to bunnings, get a hole saw, some alloy sheet, a soldering iron, then go to a speed shop and buy a 1050 Dominator. oh, and those bigger injector leads.

then go to a place that wrecks forklifts, and get the diff out of one. that way you'll have a set of 5.88 gears, and youll be able to fit a set of suitably modified EF taxi rims (say, 15x15's) because of the narrow width of the diff.

go to a truck wrecker, and get a reduction box, but put it in backwards. that way you'll still be able to cruise at 220kmph, even with the 5.88 gears.

of course you'll need some downforce at 220kmph, so swing by and see mick @ autobarn, and get the biggest alloy bolt on spoiler you can. Trust me, the bigger the better.
while you're there, get four cannons, and get them fitted in such a manner in that they're pointed upwards on a 45deg angle. the massive amounts of exhaust coming from each cannon will help force the rear of the car down.

don't worry about a proffesional paint job. its a waste of money.
find your friendly neighbourhood epileptic, hand them an open can of paint, and sit a strobe light on your roof. cheap custom paint job that will have everyone pointing ;)

get neons. 1" of neon tube = 1rwkw. just think what a full underbody kit will do for the mighty ea ;) ;)

i think those mods would be a good starting point.

sorry if i offended any epileptics. you guys rock ;)
well, shake uncontrollably, but you know what i mean

mate well spray your car for $8000, bugg $10000, we all win that way ;) LOL

man get ********* e

I have only been just got into the car seen and some one told me about the injector leads...(and oblvisly I stupidly beleaved them...)

And how much for an EF motor... instaled... I have the 4speed electronic auto... in (I know they were built for grandpa driving) I was thinking of getting a C4 auto (I think thats what it is called) in... but i don want to get rid of my engine cause it only has 120,000 on it... and its a killa of an engine(it seems to have a fair bit of power for a stock engine, more so than my old car ED Fairmont ghia that got totaled)

And I have been qouted on a paint job for $16,000...

Oh by the way my roof got jumped on and now it is all wobbly like you only have to touch it slightly and it pops in then out... Any one know how to fix it.. and how much to get a new rooflining put in...
