Ok so i bought a motor about a year ago with the intent of boosting and just now am getting into the finishing stages and then i realized that the distributor timing was fully advanced and i asked a friend a reason to why it'd be like that. He said that if the chain skips a tooth or is installed being off by one tooth, that it can run with the timing all the way advanced. And i'm wondering what it looks like in the pictures i've got compared to the way it should be set up. My friend said it looks to be a tooth off which would explain a few things. let me knwo what it looks like . IT IS currently at TDC.THANKS A LOT IN ADVANCE!!!!!!A picture of what it should look like would be amazing!

Re: ka24de timing question.... have pics.... (zerepdivad)
check out http://jimwolftechnology.com/w...E.PDF to see how the lobes on the #1 cylinder should line up when TDC (second mark from the left on the crankshaft). I have a KA24DE (92 Nissan 24sx S13) and there is exactly 8 chain links between the round mark on the exhaust sprocket and the round mark on the intake sprocket. I put the yellow chain on the round mark on the exhaust sprocket. You seem to have 8 chain links but I cannot tell where your lobe is from the picture.
Just putting mine back together a second time. Anyways, rotate the crankshaft by hand to get a feel of what the effort is to rotate it is if you decide to adjust the chain. That way after you adjust it, you can rotate it by hand again and it should require the same effort. If it binds (get stuck) then you are hitting a valve and shouldn't force it as you will bend a valve.
My distributor is advanced also but not fully, more like 1/2 of the max.

Mine is off by 1 teeth. Put it back on last night but I looked at it this morning and I am off by 1. The square grove on the exhaust. should be 90 degrees to the plane of the head. Mine is behind.
I'll take a better pic this evening with natural lighting after I re-align it.
