Ok guys, here is the situation.

I installed my new Timing belt, because old one had weird blemish on it, with Dowels pointed down on cam gears because I have markings on the outside of them as well. ( I figured it was fine before and if nothing moves I should be ok)

I had everything lined correctly and after tightening tensioner pulley I noticed the gear marks did not line up. The intake cam mark was one or two down then before all of a sudden, I am thinking the belt skipped a tooth or two while tightening. So re did the timing correctly and checked after multiple revolutions and everything lines up.

I then install my ets street kit and started the car and noticed my idle is horrible and it sounds like it's really loped (vacuum at -10 while it was previously had -18) and a slight metal noise but it sounded like intercooler pipe hitting as we haven't secured intercooler to crash beam. Could this be from a possible bent valve by tightening the pulley by hand and the intake valves hit? is it possible it's just a boost leak or I need to Adjust my tune?

Take a look at my timing marks now. (BSE kit)

I am really hoping it's just a Boost leak or this 1000 mile set up is getting parted out! :cry:

you are off one tooth at the gears. the timing marks on the gears need to be at the closest possible point to each other.

So, with the belt on, you need to rotate the exhaust cam clockwise 1 tooth, then loosen the belt and rotate the intake cam counter clockwise 2 teeth. Not necessarily exact or in that order but you get the point.
 
Looking at the picture your cam gears look slightly high. Could just be the angle though.

Line the timing marks up and turn 6 revolutions. If the marks line up then your gold. They have to all line up exactly every 6.

Take your time and double check everything.

Thanks guys, I will re do the whole thing and check back in.
The crank looks good though right?
Any damage done from running it this way for the start up?
 
is it just me or doesnt it look like his oil pump isnt aligned either. Maybe its the pic.

Nailed it, you aligned the cam gears too high. I use a ruler to make sure the notches in the cam gears are perfectly parallel with the cam gear bolts.
