my 3.9L MPI??

by **Rollin** » February 24th, 2008, 9:10 pm

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO.

Leave that crap on ebay - it doesn't work in any way shape or form.

Leave the car as is, save your money, restore your beemer, then go all out on the Falcon when you get off your P's!

by **Bazza J** » February 24th, 2008, 9:22 pm

ok, thanks for the advice
ive already got a v8 siting in the shed im gonna rebuild when it is time to drop it in,
the power i got now should do me alright til then

Please tell me how this will happen with an EA that uses a thermostat as its main means of regulating engine temperature? (Augmented by a clutchfan which also has nothing to do with anything electrical)

Last time I checked, the thermostat used temperature to open/close, otherwise it'd be called an electrostat or resistostat or ebaystat. No, I'm not on your case tonight, you're creating your own case

Advice is good. Misguided advice is bad.

i agree with Commando, Gerendasi you have been posting quite poorly..

change the exhaust and extractors, you will prob be surprised how much power that can add, leave the stock cat, they are quite high flow anyway. maybe change the head to a ticky one but no real point if you dont want to fully work the engine

by **Bazza J** » February 25th, 2008, 6:08 am

ok, so extractors are now on my list, what sort of muffler would be the best one, my father uses lukeys on his truck, would they be the best or would the muffler not make any differance

do that first, no point doing anything with the CFI. There should be a thread somewhere in these forums regarding converting a CFI motor to MPFI. In any case it's definitely been covered before, many members have done this conversion.

by **stalker** » February 25th, 2008, 9:04 am

no real difference, they are all quite good. but its all about the type of sound you want and the flow of the exhaust, im using pacemaker extractors and i think redback exhaust with a hotdog cost about 800 installed

This is rather ban stick worthy. Some people really need there balls cut off so they can not contaminate the gene pool.

would it be possible to pick the parts up for the LPG cheap for the MPI then, the machanic i got to do the conversion said that he had 2 order more parts for it cause he thoughtit was a MPI not a CFI, or did the CPI just need extra parts ontop of the MPI parts??

i've got a couple hotdogs on my spare parts pile that i might put on but i just thought that a lukey muffler might give it a little more boost than the hotdogs, but if i got 1 hotdog put into the middle and a lukey at the back would that increase the tone of the motor (i know the lukey will quiten the hotdog a little but make the noise a little more throaty sounding, as that is how my father has his truck set up)

by **Commando** » February 25th, 2008, 6:33 pm

would it be possible to pick the parts up for the LPG cheap for the MPI then,

*edit* after re-reading it now I follow you. It's possible but if you're paying for a mechanic to undertake a gas conversion (+ paying for the system) you may as well get new bits as a whole package. The mechanic may not be familiar with a certain part you've obtained, or the part may be faulty.

the machanic i got to do the conversion said that he had 2 order more parts for it cause he thoughtit was a MPI not a CFI,

that sucks, not sure what you're going to do here. If you plan on going ahead with an MPFI conversion then get your mechanic to hold on the CFI parts. I think he may be referring to different brackets for mounting the converter & mixer, possibly a different mixer and (a longshot) gas ECU? If you stick with CFI, I don't see why you have to bear the extra costs from him changing his LPG parts order? Since he'd be able to get a refund on parts incorrectly ordered... Unless a CFI gas kit costs more all-up than an MPFI kit.

or did the CPI just need extra parts ontop of the MPI parts??

not sure, see above

by **stalker** » February 25th, 2008, 6:45 pm

not really, if the lukey is a bent or something, it will be about the same as a hot dog, but if its not just a bent one then probably will lose a little, because its further for the air to travel. the lukey will give you a real nice deep sound though

by **Bazza J** » February 25th, 2008, 7:01 pm

ok, cool
i just thought id ask cause my father hjas a f350 with a recond 351 in it and a dual exaust and he just had straight pipes with 1 hotdog in the middle of each pipe and it was loud( you could litually hear him comming from about 1.5 - 1km away)
after he added the lukeys to the end of the pipes it quitened it down a lot but it still had a deep throaty sound and no u can hear him comming from about 1/2 - 1/4 km away

the machanic i got to do the conversion said that he had 2 order more parts for it cause he thoughtit was a MPI not a CFI,

i have already had the LPG conversion done and got the car back
if u r saying to take the car back and get him to order the mpi 1 and say it was a wrong order her should be able to do i as the machanic is a friend of my fathers and he done me a cheap conversion, but i was thinking i could pick the parts up from a wreckers cheap and install them myself, if they r cheap enough

but then again i might just stick with what i got for a couple of yrs (til i get off my ps)

by **Bazza J** » February 25th, 2008, 7:08 pm

oh, and has any1 tried one of them hiclones, r they worth the money ( i can get 1 for about $50 brand new), do they really increase the fuel econemy??

one of my brothers friends has one and he says it makes a differance but im not to sure

by **Commando** » February 25th, 2008, 7:11 pm

ohhhhh my bad, I should've read your previous posts more carefully mate. Nah, the LPG work's already been completed, too late there. Holmsy has an MPFI falcon on LPG, maybe you & he can compare engine bay shots & components? The only thing I'd be unsure on would be yours/Holmsys' ECUs (whether they're different or not) & how they patch into the existing respective looms?

by **Bazza J** » February 25th, 2008, 7:32 pm

ok, ill stick with the cpi for a couple of months then make up my mind about converting to a MPI when i kno about the parts for the LPG and the cost for the parts to convert it to MPI
the motor i have sitting in the shed is an old 351 out of an old fairlane from the 70s and needs doing up but will have great protental when it is done up and hopefully i will find a 5 or 6 speed box for it cheap

There are versions of these "mega-performance" chips similarly priced that tell ur ECU to pump more fuel. I heard they make ur engine get pretty hot cos its sensing that the engine's cold.
This chip looks to be the same deal

by **Bazza J** » February 25th, 2008, 8:29 pm

ok, i defanitly ruled out getting any sort of thing like that now anyway
as for the MPI conversion i have got a few questions, how much would be fair for used parts from a wreckers??, and how much work would it take to convert if i did it myself (i am only 16 and hav not much knowlage of motors when it comes to the inside of them(i only hav some knowlage on some of the parts that go on them, not much knowlage but still some)).

Nope. They make the ECU *think* the incoming air is colder than it is, so it dumps in more fuel, making it run like a dog.

A car that runs rich runs cold(er than one with the same setup that runs lean). Quick example: Oxy-Acetylene. Set it too rich (ie too much fuel), and you get a fat orange flame. You can hold it to a piece of metal plate all day long and it won't burn through. Set it too lean (blue jet) and you'll burn a hole through the metal plate.

by **G3R3N** » February 25th, 2008, 11:15 pm

Thats amazing. Wouldn't have thought running lean makes the engine hotter than running rich.
I'll be quiet now :oops:

by **Bazza J** » February 26th, 2008, 7:14 pm

ok, i got some info on the parts that i would need for the conversion from here http://www.fordforums.com/f538/attn-cfi-mpi-guys-22196/
and also a rough price,
i know someone that owns a wreckers that can give me a good price,
all i need to get now is the list of th extra parts i'll need for the LPG and convince my parents to let me convert it

by **Commando** » February 26th, 2008, 7:53 pm

lol, 2002, a lot of those guys are on here now

Great find, maybe admin on here could "transfer" some of those threads within the link supplied to over here?

by **Bazza J** » February 26th, 2008, 8:05 pm

lol, may be old info but some is stil good, cant wait til thursday to price the parts.......and hopefully find out what parts i need for the LPG for the MPI that the CPI setup doesnt have, from what i can think of ATM i will need the MPI LPG injector thingie and maybe the connections (i don't know a thing about LPG so please corrct me if im wrong)

by **Commando** » February 26th, 2008, 8:07 pm

have you contacted Holmsy yet?

by **Bazza J** » February 26th, 2008, 8:20 pm

not yet, probaly going to after i talk to the guys at the wreckers on thursday and check with the prices of the MPI parts

by **Bazza J** » February 27th, 2008, 5:48 am

my parents are hard to presuade, they keep saying things like "if it works don't fix it", and telling me the CPI is fine the way it is and that a few ppl might be BSing bout the mpi being so much better,
i already told them that you can get better fuel econemy out if an MPI,
what else can i tell them about it without mentinintg the power gain to them much (they dont like the idea of me in a more powerfull car)

by **Malakai** » February 27th, 2008, 7:06 am

Look I think you should just leave it as it is, you have spent money on the duel fuel and it is just a CPI EA (although being a 5 speed is something, better than a 3spd auto that's for sure), drive it till your off your Ps then look at something better then. Seriously if you have to ask your parents to do something and they give you grief about it then it's going to be hard to get anything done. How long have you got to go on your Ps?

by **Commando** » February 27th, 2008, 7:32 am

Tell them that CFIs are known to blow the welds on the intake, MPFIs have never had that problem

by **serial_fool** » February 27th, 2008, 7:41 am

A multipoint conversion...

Theres really no point in doing any performance mods to a CPI engine- go the MPI and you'll receive an extra 10-20 kws.

i've got about 6 weeks til i can get my ps, i think i will leave it a while now anyway, or if the engine craps itself then i will convert but until i atleast get my green ps i wil leave it as is, it still does hav great power for a 20yr old car

if i dont convert it i will hav more cash to spend rebuilding the V8 in the shed and giving it a bit of a boost (not that it needs much for me)

Commando wrote:Tell them that CFIs are known to blow the welds on the intake, MPFIs have never had that problem

has it happened alot or just a couple times

and also i heard that there is a holley for the CPI engines but i tryed googleing it and didnt find anything

by **Commando** » February 27th, 2008, 5:09 pm

the CFIs are fuel injected. No Holleys.

my comment was tongue in cheek btw.

by **Bazza J** » February 27th, 2008, 5:16 pm

kk, i'll, keep the CPI til the v8 is ready then boost it

by **Bazza J** » March 15th, 2008, 7:32 pm

just installed new solinoids (old 1s craped them selves, and old remote wont work propaly), ive tryed looking for the old Control Module to swap with the new 1 under the dash and under the bonnet and i coulndt find it i know what it looks like but i just dont know where to look for it, i know tracing the wires will find it but that takes alot of screwing around, would any1 be able to think of any spots that most pro alarm fitters fit them to

thanks

p.s none of the sets are factory

by **Bazza J** » March 16th, 2008, 8:10 pm

i found the old Control Module, it was in the drivers kickboard, replaced it with the new 1 (alot of cutting and fitting wires) and now my remote locking is working perfectly exept the lights dont flash when i unlock/lock it but it can open it from a block away, so i am happy with the new system,
also i fitted my new stero 2day, i will be fitting my new 6X9s hopefully on friday,
i also have a button under the cigerette lighter that makes 2 little lights on the dash blink and when u try to start it when they blink it wont wind over until u trun it off, the otherday i noticed it wasnt working, i had a look at the wires atatched and there were none loose, could a fuse of blown, or the lights blown..

update:
my father decided to sell the bmw that i was going to restore, he has agreed to get it going first but we just won't keep it as it is just taking up room,
i hav decided to do more on the falcon than the bmw now so i am wondering if the people that have done the mpi conversion could list the parts required to do the conversion, (and the parts that are differant for the lpg if possable)
i am trying to decide weather to paint it or to convert it to MPI, as dad's freind is an ex-machanic/panelbeater and can do it for the parts cost only and has enough time to do only one of these things

by **wolf** » May 31st, 2008, 3:04 pm

to go to mpi i think you will need a new fuel rail, injectors,computer and i am not 100% sure but i think you will need a new fuel pump(not 100% on this but i am sure someone will correct me)

by **Bazza J** » June 1st, 2008, 6:25 pm

so i don't need a multi point head, auto teacher at skool said i would need to strip the whole block right down and basicaly start from scratch

by **Bazza J** » June 2nd, 2008, 12:45 pm

i got quoted $450 for an entire ea falcon 3.9L multipoint at a wreckers, because to remove the parts would cost more than the whole car, i am thinking that i could get the whole car and get what i need out of it and sell the induvidual parts separatlly, does anyone thinbik i would get most of my money back if i part the car???

Who is online
