EA Turbo AIT Ford builds --go the problems--

Just wondering if anyone else has a EA turbo outfitted from a company called AIT I havea few questions about the build and was hoping some one had some answers

--The 7th injector is ment to richen up the mixture when above
atmospheric boost however mine seems to run all the time and cause my car to run like a pig, disconect it and it runs fine (well apart for the other problems) does anyone have any ideas?

--before i had the new Gearbox and engine put in the car at about 200 would feel like it was going to shake it self apart but last night a had a bit of a race with a holden git (standard six) and at about 150 i put the foot on the clutch and it felt like the gearbox was going to be left behind (should you put the clutch in at high speeds or let the engine pull your speed back down)

--I also keep having a small problem with the engine (long time problem)
I have narrowed it down to the electrics (90% sure that what it is) I previously changes the dissy cap, rotor button leads, cleaned spark plugs and had the coil replaced. When driving it feels like the engine looses its spark, feels like two or more cylinders die out and then start firing again tis a wierd one (engine doesnt backfire)

-- finally I know all EA when you start them tap a few times then go quiet mine latley however seems to tap for long lengths of time Im not sure it its something in the head or the oil pump (oil level is fine) any ideas

check that the extra injector controller is running properly and that the map sensor isnt on the blink.

i cant see what putting in the clutch at high speed would do, but letting the engine rev down is still better as it slows the car down better and in a more stable fashion

have all ur injectors prefessionly clean and serviced, if all ur ingnition is reletivley new then i am nearly 100% positive this would be the cause. also may pay to replace the fuel filter.

sound to me like one (or a few) of ur lifters have gone on the blink, i'd advise replacing them with a new set of ef ones.


cheers.joe.

ps. let us know how you go.

Re: EA Turbo AIT Ford builds --go the problems--

check your oil level too - if there isnt enough oil in there they will tick on startup - kind of an accidental low oil level reminder that ford made lol.

your third problem might be related to the first, if the 7th injector is always running, it might cause your car to run really rich, this can kill the spark or at least cause you to loose power.

Re: EA Turbo AIT Ford builds --go the problems--

Yeah, I recon GMDestroyer is spot on.
1. Sounds like auxilary injector system isn't running corectly
2. There's no real problem with putting the clutch in at speed, but using the engine to slow the car down lets the motor settle, and also works as a second set of brakes.
3. Maybe you should replace all of your spark plugs with some performance type ones, instead of just cleaning them.
4. The tapping sound is the lifters. You canget a full EA set at under $300 trade price.

GMDestroyer: Is there any advantage to using EF lifters??

Re: EA Turbo AIT Ford builds --go the problems--

i was told by my head builer. that the ef ones are pump up hydraulic ones and are better designed then the old ea ones, then tend to last a fair few miles more then the ea design.

cheers.joe.

Re: EA Turbo AIT Ford builds --go the problems--

All of the lifters from EA right thru are the same design - ie. they're hydraulic "pump up" type ones - the physical design is also pretty much identical except that on the EF ones they use a metal cover or cage to retain the little valve follower ball whereas on earlier ones that cage (I think it's just called a retainer in the workshop manual?) is plastic and is fairly easy to break. Also on the later type they've used what looks like nylon for the lifter retainer collars / rings (they are NOT seals!!) which are on the body of each lifter and both hold them together and retain them in the rocker bores - rather than the crappy brittle shit of the earlier ones.

You need to be careful tho of the diameter of the lifters - in the EA-EB-EBII (ED) workshop manual they make reference to "Early Production" lifters and "Late Production" lifters - their physical design is identical but the early ones are a larger diameter (I think 14mm vs 11mm of late production?).

To be honest you'd probably be best off just sourcing a complete EF rocker assy from a wrecker - I picked up a complete set ready to bolt right on (ie. including lifters) for $170 and from what I've seen on the forums that was a ripoff (normally they're available cheaper than that).

Re: EA Turbo AIT Ford builds --go the problems--

I will be taking the injectors up to Kalgoorlie when im up there as I have a mate in a work shop that can clean them for a carton of beer. also I will probable replace the map sensor and the hoses as I think they might be leaking somewhere. If the lifters are stuffing up ill get it done under warrenty (if I can) as its a recon engine with only about 20000 on it. Ill take the rocker cover off and have a look anyhow might be something easy.
