right then, my car went into a vw garage on friday to have its 3F GT lump put in.
My mate and i were helping and doing most of it under his instructions ( that way i get it done for free)
engine went in fine and all seemed well until it cam to wiring.
he has given me a list of things to ask :-
(this is exactly as he has written it)
we need an idle air control valve and the postion of it
Multi plug for fuel tank and fuel pump
which pipe out of the tank if flow and which is return ?
also on fuel rail where does flow and return go ?
on the fuel tank which connecter is supply, fuel gauge, and earth ???
we have got the lump in, the ignition system converted, most of the connecters in place, but there is one on the injector rail which we dont have a clue about ?
please please help, detail would be great also any pictures etc would also be great....so all you 3F GT owners please show me your set up!
help
thanks
help me with my conversion please....i want my car back lol
The idle control valve sits at the back of the engine, under the inlet manifold, on a little bracket fabricated to the metal water pipe that comes from the water pump.
As you've probably noticed, you may need to swap the mulit-plugs over if you are changing the fuel pump for the GT one. I've been running my GT conversion with my 1.0l fuel pump for around a month now with no fueling issues what so ever, but I'm in the process of changing it with the fuel tank, for piece of mind. While you're looking for the multi-plug, you could judt use your normal fuel pump for now.
I'm assuming you're asking what the return/flow pipes are on the tank, because you are changing the lift pump. You don't need to do this. Only the inline pumps are different on GT/G40s. However, IIRC, the blue is the return and the black is the flow. One the fuel rail, the return is the pipe with blue stripes down it, the other is the flow. The return goes to the fuel pressure regulator (a little brass coloured thing that points away from you as you look at the engine) and the flow pipe goes to the start of the fuel rail.
The plug on the injector rail, which I think you're talking about, is the plug that goes to the Idle Control Valve. This just plugs into it and two pipes come from the valve. One to the bottom on the inlet manifold, and the other to the throttle body elbow.

conversion
well the only thing is we dont no where to wiring to the fuel tank and pump come from n the engine bay?
we have tried to trace wires which we "think" are fuel pump wires but had no luck.
when we installed the new loom, we only did the ECU loom as the lightinf loom was fine. (by this i mean the white connection block which is the left hand side connection on the fuse box)
this is all we changed as the other loom was fine.
where abouts is the connector for the fuel pump and tank, please help
thanks

thats funny, as one loom plugs into the other at two places, there is a three pin plug next to the ignition coil and another three pin plug near the ECU. presumably then the MH loom has the same plugs. When you convert a lesser mk3 to a GT you have to change both looms as these plugs are different (the one near the coil is 2 pin and the one near the ECU is 5-pin.)

well fired her up last nite.
was a bit like a horror movie as there were wires and pipes everywhere just to see if she would run before dark.
did notice a couple of problems though, slowley being cured and some not !
firstly :-
cluctch was slipping a bit, put you foot down in gear... a lot of revs but not a lot of movement, we checked the clutch before we put it in and it looked fine, we tried a few things..giving it a bit more free play which helped slightly
do you recon it could just be because the lump was outside and the clutch had a little surface rust and was glazed a bit i.e should be give it a day ??
next
water heats up real quick, we recon it could be an air lock, broken thermo or blocked rad! what do you recon
also the rev counter dosent work. This is because we had to wire in a mk4 polo coil, where is the rev counter wires and where do they go ?
other than that fine....i think just gotta shack it down for a week or so
