Dizzy Direction

[EA_Bender]

me again...

im doing the MPI conversion next weekend :1syellow1 one of the few remaining questions i have is about the orientation of the dizzy. On the cfi models, the tfi faces the rear of the car, on the mpfi models, it is rotated 90 degrees clockwise so it faces the front left wheel.

Do i need to do this?? if i dont, then sweet, if i do, is it just a case of lifting the dizzy out and rotating it?

thnks in advance

I didn't change mine.

You are fitting the MPFI dizzy when your doing the conversion right? ;)
(yes i know you dont HAVE to, but you should)

With MPFI and CFI the dizzy backet is in a different position. you will find there is a bolt hole on the oposite side of the dizzy for MPFI (closest to coil side)

You should move the dizzy to the MPFI position as you would see in the Workshop manual as it makes life harder i found in the CFI position... cant remember why thou :P

U can use the cfi dizzy no problem & its easier to move than
the mpi as the bolt can be undone from left to rotate.

um, id just planned on using my cfi one.. im not sure exactly what the difference is between them.

so basically i can use my current cfi one AND leave it in the same position without touching it? is that right?

thnks for the replys

The MPFI dizzy has a smaller tooth off the spider gear. The car will idle ALOT better with the MPFI one, you can use the CFI one for the time being but id be definitly changing it to the MPFI one, or changing your spider gear in your dizzy to the MPFI one. Your auto electrican can do that for you.

ok, i might rip the dizzy off the wreck ive been getting my parts off, after u undo the bracket, do they just pull straight out,

hmm, that means im going to have position it all correctly, and ive got no idea what im doing there, i might just get the dizzy but leave the cfi one in till i can find someone that knows what they're doing

do u think it would be easier getting the mpi dizzy and gettign all the timing set up properly or getting a new spider gear put in?

Providing your MPFI dizzy is in good nick, its easier to change that then swapping spider gears. You can just leave it for the time being then get a mechanic to change it for you ;) if you dont have a timing light and experience in doing it

The mpi & cfi dizzy are total mirror reverse of eachother. U can not
rotate the dizzy at all, as tfi etc is on opposite side.The only reason
ford origianally reveresed the dizzy was so u could remove isc solenoid
housingto gain access to rotate dizzy. (MPI)
With the cfi Dizzy is so easy to rotate for timming as the nut is easy to undo being on left side, as it is not obstructed by injector manifold.
Both dizzy are identical to look at, only reverse of each other so dont
listen to tales of differences i rung ford & this is a fact.
They are identical in structure.

Id go back to your home brew cause I think your wrong. ive got a MPFI dizzy and CFI dizzy in the garage and they are IDENTICAL cept for the spider gear :

You have have it on the Left or Right with the MPFI dizzy, ive had it on both and I can get to the bolt on the RHS easy as with a long extention.

[EA_Bender]

the dizzy's are exactly the same, im looking in the manual right now..

i think what ill do i leave the dizzy exacly how it is, ie. cfi and in the same position, see if the one at the wreckers looks ok, and put that im when someone can help me with the timing cause i have no idea.

if i dont change anything right now, i shouldnt have any troubles, maybe just a bit of a rough idle and ill get the rest sorted out later

just to add onto this, why were the positions moved in the first place? did it foul on something?

[EA_Bender]

also... do i need to get a longer air con belt due to the position changing from the cfi to mpi or is there a tensionor on that belt somewhere?

[SileNceR]

there's a tensioner, between the balancer and the compressor.
belt is the same.
