So what your saying is we turn the crank by where the crank pulley is and see if the piston is on top and thats how u mark the timing. Am i right on this?

WTF does marking the pulley have to do with setting the timing? How the hell is that gonna change anything?
If your car isn't timed properly when you set the ignition timing, ect... then it will be way off. You won't get maximum power from your motor. That's the big deal I know you all care about ;-)

Rep Power: 414 Gah! I guess I'm not making myself clear enough.
When you turn the crank, that moves the piston up the the top of the cylinder. Then you put a little mark on the pulley. How on earth does that change the timing? Would you have to tighten a bolt or do something else? I think I am just totally missing the point of this whole thing because I keep hearing the same answer over and over. It still isn't making any sense to me.
BTW, yes, I am retarded.

Rep Power: 0 What I'm getting from this is, you mark the pulley when the piston is at the top, then you rotate the pulley to line the mark up with the timing mark on the cover, attach the belt and your good to go. Is that right?

Ok the #1 piston is CLOSEST TO THE TIMING COVER. You mark the puley to know where your timing is then you use that on the distributor, ect...to tune the car with proper tuning. If you go to tune your car and have no idea where the timing is then you wont be able to get the peak HP from it. It wont make sense till you are on a dyno trying to make the most power from your setup, or you take it to someone to tune it. I can't explain it because you guys have never done it so it wont make any sense till you have seen it done.
admitting your flaws is your first step. good job. There is a mark on the timing cover you can see it. When you have the piston at top dead center then you make that mark on the pulley at the same spot the mark on the cover is, dont move the pulley or anything like that because it will just move the spot. You see the mark on the cover and just make that on the pulley.
The mark on the pulley is to know where the timing is, then you can tune the car properly. I really can't explain it, it will never make sense. Take it to a dyno and let them show you in person how it affects the performance.
I think I understand it, sorta. Move the cylinder to the top, when it's at the top make the mark on the pulley to set timing straight. I understand, I think lol. I guess this is to make sure everything is straight when you put the belt on/tighten everything, right? Please don't hate, I'm just the new local slow thinker ;P.
ok how about this haha, first person *cough* fly *cough* that does a good diy, including pics and captions etc for the pulley install, gets some points or something from each of us wanting to know how to do this. its probably a lot easier than were making it out to be, and its definately harder to explain things over the net instead of face to face. What do you guys think?

Simply, the mark you are putting on isn't changing the timing. It's setting up the basis for the stock timing. When you go to a shop and get on a dyno, the shop will retard/advance the cam gear Xdegrees BTDC/ATDC. Setting the notch in the pulley just let's them know where TDC is to begin with. There is a relationship between the crank pulley and the cam gear that nobody has talked about yet in this thread, and it may be why you don't understand.

Rep Power: 813 Wow now I'm really lost. So to have the pulley installed properly, it has to be tuned? So you put a mark on the pulley that matches the mark on the timing cover when the piston is up. Then a shop does something? So the pulley won't work until it's tuned?
What needs to be done during the install? And where's the smiley with ?? above his head, cause that's me right now.

When u install ur pulley, rotate the crank till the #1 piston(the one closest to the pulley or on the right side looking at the engine from the front) is all the way at the top. Then u make a mark on the pulley at the place where the mark on the timing cover is. That is it.
What boosted Boosted2k2 is saying is that putting the mark on ur pulley allows anyone who trys to tune it know where the pistons r at any given time allowing them to adjust varioius other parts of the engine to maximize performance. You dont need to tune ur car at all to get the pulley to work. All tuning allows u to do is to get the most out of the pulley.
I hope that clarifies some things.

Out of all the people in this thread, it odd that nobody understand this. I think I know why Fly doesn't. Just because you are putting the mark on the pulley, doesn't mean you are CHANGING the timing. Think of it better as "standardizing". You are placing the mark on the pulley to indicate TDC for the #1 piston.

Josh, you said you had 2 D17's at your shop in another thread. Give us a pic!!!!

Rep Power: 414 So we can just slap it on and it wont screw up the engine if we don't worry about this timing crap? My shop can figure it out once i get it in there to dyno tune the VAFC II, etc.
