when i put in the crank how much do i torque down the bolts and is there a specific order the bolts have to be put in and with the pistons is there a way they need to be facing when they are put in

Yes the pistons fo in a specific direction(for OE) look for the arrow on the piston.

As for specs and order for the bottom end, I would need to know what engine it is.

I am assuming its for a d16 of some kind so here is where to start. As for TQ specs, i need to know the specific engine.

If you didnt do this first step, go take the block to a shop and get it checked(or as mike said, go look for a new block)

Torque sequence

Camshaft Specs
Special Note:You can use a D16Z Cam in a D16Y Head but you have to use the Cam Gear from a D16Z because it'll be a 1/2 timing tooth off..same goes for D16Y cam in D16Z Head,just use Cam Gear for a D16Y..Do NOT buy any aftermarket Cam Gear for a D16Y from a company if they only have one Cam Gear available for the 88 thru 00 Ds.I recommend and use a AEM Gear,they have the right Cam Gears for 88-95s and 96-00s

factory service manuals. log in, download. anything you could ever want to know about your car.

http://www.hondahookup.com/manuals/

but like i said, if you built this thing yourself and cant even find the simplest of all, the torque specs, then i would seriously start looking for another block

just my experience with stl built engines....
