Pinging and Popping after Engine Rebuild (video inside)
Yea I had to rebuild another motor 
I finished rebuilding a 99 RS ej25 for my car today. I spent a good amount of money at the machine shop getting all the parts serviced.
I basically had everything redone. Reseated the valves, shaved the heads, shaved the block mating services, line bored the block, rehoned the cylinders, bored out the rods for new bearings, all new rod and main bearings, ground/shaved the crankshaft, new piston rings, new hg's, new timing belt etc etc
everything that should be replaced/maintained was done so it could be done right.
I finished up everything today and went to start the car but it took a little coercing to get it started. Once it did, it didnt sound very good. There was a bit of mild (not loud) popping from the exhaust (stock) and some pinging from the motor.
The car idles, but it almost sounds like its running off 3 cylinders or something. air coming out of the exhaust doesn't feel as even as it should
It's when you give it gas that it doesn't want to rev up
Also, when the car was off it sounded like there was oil or something burning in the header, a sizzling sound if you know what I mean.
I'm pretty sure the timing is right. Went by factory specs and everything, cams were definitely lined up, crank at tdc belt was new/tight etc
I have no idea what is going on. really disappointed right now I just spent a ton of money and time on this and now it **** on me

just for timing sake you can kind of see the timing marks on the cams and the crank if you look close enough, definitely lined up
