The reason why people tell you to search is mainly cause this has def been answered. But ill take the time to help considering i am doing this now.
1. remove the head we are going to work on the block right now.
2. remove the oil pan, now you have acces to the oil pump and oil pick up tube.
3. remove the oil pump and pick up tube, the pick up tube has four bolts i believe. the oil pump has five 10mm bolts on the side of the block.
4. once that is removed the rear main seal housing can also be removed. i believe that is also has five 10mm bolts.
5. now you can remove the main bearing. its ten bolts on the bottom.
6. now remove your crank shaft.
Now that your bottom end is disassembled you can decide what direction you want to go in.
If you decide turbo, buy suited parts for a turbo build. if you choose N/A buy parts suitable for that.
When i say suitable parts im refering to Rods, Pistons, Main and Rod bearings, Thrust washers.
once you decide what you want, IMO the best thing to now is take your parts to a machine shop. Have your block cleaned, degreased, honed (if needed), and milled. I would aslo have your crankshaft balanced and grinded(if needed). Take your oil pan there and have that degreased and cleaned. Also depending on what rod and piston set up you choose, some require that the block be notched and in some cases even the main bearing cap.
From here with the block, crankshaft, rods and pistons installed by a professional (best way to do it if your not familiar with rebuilding), you can now purchase an oil pump, oil pick up tube, and oil pick up tube gasket.
With these parts installed along with the rear main gasket housing with proper sealants, you can install the oil pan. Now you have a fully built bottom end.
Brands I would suggest; Eagle Rods , FJ distributors Rods, Vitara Pistons, CP Pistons, I plan on using thses and from what i understand they can hold 500+ HP. ACL bearings, Duraglide bearings (not sure if they are the same brand) for the rod and main bearings.
As far as converting Your cylinder head fortunately i have a VTEC vehicle and engine i do not have to rewire anything and im positive when switching from Non-Vtec to VTEC there is a need to rewire. Also if you are coverting from a automatic to a manual, im pretty sure if you can get your hands on either, a EX manual ecu, and a EX engine harness, or a P28 ecu (OBD1) with a (OBD2-OBD1) conversion harness to match with a EX engine harness, you will be in good shape. And with the P28 you can now easily tune your car.
So since you said your going with turbo, purchase a full kit, if you do not know anything about rebuilding or Forced Induction i wouldnt even attempt to piece together a turbo kit.
Well this is about as far as i got, the cylinder head is a whole other can of worms, Including, Cam (SOHC), valves, valve seals, springs, retainers, and im sure im forgetting something.
Hope this helps man. GL
