I searched, but couldn't find specifics on this subject. I am soon going to install the 2GCDFIS w/ TT and I will need to reset my timing. I don't know how to do this, nor do I know what is needed. So throw in whatever you know. Hopefully you all can help out enough step by step with whats needed and this could be archived for people's viewing later on. Thanks.

 

It's on page 5-36 of the FSM. I'll let someone's who's actually done it on a 7 answer though.

I'll need to buy a timing light, anyone know what type should be avoided?

 

Yes, the haynes manual or the FSM will show you how. Basically, you connect the timing light to L1, run the car at idle with it warmed up (about 800 rpm). You should see the first mark on the pulley close to the timing pin. If it isn't lined up, loosen the bolt/nut that holds down the distributor. Rotate the distributor until the first mark lines up with the pin. Tighten down the bolt/nut that hold down the distributor.

Now connect the timing light to T1. The second mark should line up with the timing pin. If not, there are 2 extra screws with slots on one of the vacuum advance pots. Loosen these two screws and move the pot in or out to line up the 2nd mark with the pin. Now retighten the screws. If the trailing was set correct before, you probably wont have to change it with the TT.

These instructions are for stock timing. Some guys on here set there timing at max mechanical advance (over 4000 rpm). You will need to mark your ppulley or get one that already has marks (like the RB pully).

For timing lights, I know Jeff20B recommends the cheapest light you can find. They usually work just fine. There are two main types of timing lights: DC and inductive. Inductive is more convienent as you just connect a clip over the spark plug wire. Sometimes though, people have a problem with picking up the leading signal when connected to trailing. The DC lights connect directly to high voltage. You have to disconnect the spark plug wire and connect the light between the wire and the plug. These lights are cheaper, but more difficult to use. Don't worry about any fancy features like advance dial, digital readout, and so on. Just get something simple.
