Hi everyone,



It seems that everytime I'm posting on here it's with crazy issues. We have a customer's FC here at the shop. It arrived in pieces, with a damaged, modified engine harness and three boxes of bolts, gaskets and hoses.



I was looking to get help in identifying some parts as we're not rotary experts yet.



Thanks!

This hose- is there a surge tank on this car? There isn't one in the box.

Injector clips- these have been spliced for the primaries. It looks like the primaries we have in the box are the correct ones but the clips on the pigtails attached to the injectors in the box are grey, not red. Furthermore, the wires attached to these red clips are a larger gauge then the wires on the primaries that came in the cardboard box o' parts.

With the split loom wrap removed we see the hoopty splicing job. I think what I'm looking for here is a picture of an unmolested harness, a shot of the injector area.

Is this the correct waterneck for a 1988 turbo II? It seems like the stock hose is loaded too much when attached. Also, what are the two white connectors at 7:00 to the waterneck?



Thanks so much guys.

I think you need a wiring schematic. I don't know how much pics will help.



That first pic looks like the exhaust hose for the ACV.



No, I think that neck is from an S5. S4s were always metal afaik.



I'm kinda amazed that you would take such a mess on. Is business slow?



Cheers

good luck getting that thing sorted, looks like ur starting with quite a mess. Is the motor even good?

1. Breather hose to the factory air box to quite box behinde headlight for AIR PUMP.

2. high imp S4 injector clips 550cc.

3. Wires are part of the BACV, O2, and Rear rotor Injectors.

4. That is a S5 neck 89-91, the connectors are part of the ACV the big block off plate you see, note the ACV has been removed and blocked off.



The electric fans are drawing more amps then that alt can handle and should be addressed.

Is that OMP electric? It looks like someone may have swaped a S5 motor.

You guys are great. Starting at the top,



Business has never been better for us, I know this seems like some kind of charity case job but it's one of the things I like a lot about owning a shop. This is a great way to learn more about this motor for one. Second anything i do will be an improvement so if I'm up front with this customer about time and expectations then everyone leaves happy.



This is one of the things people like about our shop, that they can come in with projects that they aren't able to finish and not be faced with massive ego, or be made fun of and I'm proud of that. This is a risky job but I'm realistic.



One major attraction to this is that the engine is factory new, so as Ice said, this could be a different version than what was originally in the car. It also has questionable history with these poorly executed modifications.



I appreciate the wiring harness link. My next step is to shore up the leaks, and run a pinout on the ecu to the injector wires to make sure that each injector has the correct clip on it.



There are two water pipes on the top of the motor. They're about 1/4 diameter OD. Where do these go to? One is pictured with a blue hose attached in the above picture.



Please appreciate how hard it is to get a car like this without having a very intimate familiarity with it.



Thanks,



Alex

What should I recommend for an uprated alternator? I know of a place that will build to my spec in any case but perhaps there's a factory upgrade to drive these fans? Thanks for the heads up on that.

The blue hose is a bypass hose for the TB mod. It went to the TB to warm the thermo wax pallet for the AWS system.



For the ALT I hope your wallet is thick http://www.mechman.com/alt.htm or you can modify a FD ALT.



If each of the injector plugs has 12v on one of their sockets, then visit the ECU and its small yellow plug. With the key to ON, check for 12v at each injector wire. Your checking the socket on the small plug, not the ECU.



The 12v at the solenoid resistor comes from the Main Relay. The Main Relay should be hot from EGI INJ fuse in the engine fuse box and also goes to the coil assembly’s. Black/Yellow wire.



The voltage for the injectors comes from the EGI INJ fuse to the Main to plug X-16 on a 87 series four (called FEM-02 on a 88) then to the fuel injector and then to the ECU pins 3C, 3E, 3F, 3H the ECU flips ground on them in turn momentarily.

Sorry about that I got onto a S4 binge here thinking low imp. That resistor pack will not be in this car. So bypass that.

Its got an s5 turbo manifold on it also, probably a complete s5 engine.
