Re: Fuel line question

Yeah, high pressure fuel on 1 side of the regulator and low pressure on the other. The regulator sets the fuel pressure.
The return side has a rubber hose with a simple spring type clip on it.

Re: Fuel line question

You have an internal fuel rail in the inlet manifold and the fuel travels from the rear to the front and out through the regulator. Tom's did a bolt on adjustable FPR but very rare these days, you may be able to convert the original regulator with a B&M kit or use an adapter and remote mount an ...

Re: Fuel line question

The fuel return is at the front of the engine from the fuel pressure regulator (FPR) there's a short hose about 3 inches long between the FPR and the steel pipework under the throttles. The fuel feed is at the back of the engine through a banjo fitting. The manual states there should be 34-40 psi of...

Re: engine sealing questions

Oil pan is FIPG sealer.
Oil pump has a gasket.
Each injector has 4 o-rings, 2 fuel, 1 to seal against the manifold and the other is on top between the injector and retaining plates.

Re: Two tone panda scheme

Oh and on the arches it is approximately 8mm of white and then into black in the above photo. This is another thing that can drastically change the appearance of the 2 tone paint job.
The funny staggered line on the rear pocket is how mine was painted from factory.

Re: Ignition key source

Consider Run as ON.
The black and red wire is +B so it powers up the ecu and T-VIS solenoid and is in the Diagnosis box as +B.
The black and orange is used only for the ignition coil and igniter.

Re: Ignition key source

Use the original wires where possible. So use the black and red ecu power wire to power up the ecu, use the coil and igniter power wire to power up your new coil(s) this is probably black and orange.

You can connect your new pump to the original wiring at the tank. If you decide to connect the Green and Red wire to a dash switch with the other side of the switch connected to ground that will work fine but from a safety point of view in an accident the fuel pump will keep pumping unless you consc...

Re: 4age on bike carbs

1. The tacho signal comes from the igniter (black wire with red rings in an AE86) it is also in the diagnosis connector as IG- if you trace this wire inside the car you can find where to connect your new ecu output to it. Also you may need to use a tacho adapter between your ecu and the rev clock, t...

The blacktop VVT operation is off at low rpm, on during mid rpm and off again at high rpm (your cam spec will determine what your engine prefers), unlike the silvertop that is off below 4400rpm(ish) and on above that rpm. Check for fault codes, make sure the throttle position sensor is set within sp...

Using this:

and inputting the stock 14" Intra wheel spec of 6j +21 against yours, you need 32mm of spacing just to match the inner wheel to strut clearance.
