4AGZE AE82 Situation

[cogent]

Alright,

I recently bought a AE82 FX-GT hatch off trademe for $1500. It has a 4AGZE swapped into it, and im trying to identify which 4AGZE it is.

- It has DLI and not a Dizzy. I believe AW11 Ones were dizzy.
- The 'supercharger' writing on the cam covers is upside down when you look at it front on. So possibly from an AW11 afterall?
- It is MAP sensored, I thought AW11 ones were AFM?

Additional to this, the wiring is awful. Absolutely awful. I'm having a hard time believing it ever started at all, let alone 'in the last few weeks'.

So what I need to know is:
-how can I identify which GZE engine it is
-should I bother with the current loom or should I buy a new, unmolested loom and adapt it into the AE82 loom as required.
-Where can I find wiring assistance for this swap, and if there is none, what should I be looking for to piece one together?

cheers

Edit, I will add: Cranks over fine, no spark no fuel. When ignition set to 'on', no check engine light, when TE1+E1 are Jumpered from diagnostic connector, no codes thrown. o2 sensor unplugged so it should be throwing a code for that.

look for the external oil drain on the back of the head.

That will identify smallport or bigport for a start.

hmm, cant see one. Where exactly on the back of the head would it be? I assume by 'back' you mean the exhaust side. There doesn't appear to be anything on the exhaust side of the head, and its a bit too cramped to see on the intake side but again doesn't appear to be any form of oil drain.

Right at the back corner on the intake side, and re-enters the block about 1/2 way down at the back.


If it has no oil drain and a map sensor, then it is a mismatch of engine and ecu, and could be anything.

[cogent]

haha $&#$% slam dunked this motherf**er. I scored me a smallport.

So we DO have an external oil drain from the head (on the gearbox side, intake side, about half an inch to 3/4 an inch thick?) going down to the block. We DO have a map sensor and we DO have DLI.

Now I need to decide if I can rescue this wiring disaster.

There's lots of shitty splicing, really shitty splicing. 'twisted together and wrapped in tape' would be preferable to some of the connections.

Additional to this, someone has been poking around with a multimeter, and has jammed it straight through the wiring insulation and into the wires. So HEAPS of connectors have pinholes exposing the bare wires. I can forsee corroded shitty wiring in the future.

if anyone wants to discuss this in real time, feel free to hop on MSN at n.turner@orcon.net.nz or ICQ 174677177 - just chuck 'toyspeed' or '4agze' or 'you own hard bro' in the authentication message box

So it could be AE101 or facelift AE92, need the ECU numbers to confirm, as they are different
I dont know what one is what,
but someone on here will.

[cogent]

ECU numbers are

89661-12790
4A-GZ
175700-3372 12V

plugs are
[ 26P ] [ 16P ] [ 22P ]

hahaah i got prety much same shit cept iv turboed, my wirings a mess 2 i tidied it up some what but the ecu still sits in teh engine bay but getting a ems intalled this weekend, what are u planning on doing with the car? turbo? bigger pulley? or just leave it?

[Rick]

Your ecu is from a AE101 4AGZE, the last generation of the 4AGZE motors

[cogent]

Well thats good news then. Odd the 'twin cam supercharger' etc text on the cam covers is upside down, but I guess that doesn't really matter if its supposed to be covered by an intercooler.

I might give import customs a call, im pretty sure the guy out there is a 4A wiring master.

[rollaholic]

for your interest, the cam covers are all the same throughout the 4agze series - ie, AW11 styles

[xsspeed]

you do know he comes on here

[cogent]

Yeah, but If Im going to get his help I might as well just pay him to sort it out instead. People gotta make a living you know!

Funny about the writing though, I thought only the french did things backwards

[xsspeed]

I was more meaning if he knows your a toyspeeder he might hook you up? I don't know how he works.

[thegreatestben]

if you mean hamish from import enhacncements, he's no longer there.
Works for AJ autoelectrical now.

[cogent]

Im gonna try find the AE82 pinouts and AE101 pinouts and have a crack at rewiring it all.

Can anyone suggest a link that will give me an indication of where I need to link the GZE loom with the AE82 loom?

[ChaosAD]

try the tech reference section at club4ag.com

use the ae86 diagrams for the fx loom as the ae82 diagrams on there are the afm ones

[Crucible]

I tried an ecu out of an later map ae92 gtz in my ae101 today and it wouldnt start, put the old one back in and fired first pop, the numbers were differant. but had the 4A-GZ as they normally do

for the record lol

Yes AE101 and AE92 facelift are both map sensed, and both have the same ECU plugs,
and are wired differently,
so do not interchange.

[cogent]

club4ag have comparison diagrams between facelift ae92 and ae101 pinouts.

I managed to separate the GZE loom from the fx loom, but theres like a second sort of custom subloom made which goes to a few things in the engine bay.

So i'm on the hunt for a uncut ae101 4agze loom now, and depending on how bad it is then possibly a uncut fx body/dash loom
