Checklist of parts for forged engine rebuild

[theurgy]

Hey guys,

So I'm in really early stages of planning out a full forged engine rebuild.
My plan so to build completely up to stock compression, bore and everything, however instead using a set of forged pistons and rods.
I'm going to start ordering small sets of parts and stock piling them now. Small payment plan in some way...LOL At least before I pickup the expensive bits.
This would also be a rebuild of the top end as well.

I'm not worried about what rods/piston combos I'm going to use, it's all the other parts that people forget to factor in when doing a rebuild. Things like gaskets and studs, and bearings, and all that good stuff.

Can anyone post an absolute comprehensive list of the parts one should pick up when preparing to do a full forged engine rebuild, if they require OEM Mazda parts, please let me know those part numbers as well (if you have them).
I will gladly update my initial post once you guys post them up, or if someone has already posted this in a previous thread.. even better (I did search though).

Off the top of my head I can think of:

Pistons
Rods
Intake Valves
Exhaust Valves
Valve Springs
ARP Head Studs
ARP Main Studs
OEM Crank Pulley Bolt
Rod Bearings*
Main Bearings**

Do I really need all the gaskets in this kit?
MAZDASPEED 3 Complete Engine Gasket Kit
Would this be worth it?

*Anyone know what clearances I should be looking out for, or is that more a matter for what rods I pick?

**Stupid question, but how many main bearings do we have in our engine? And do I need to change these if they are still good or are bearings one of those things you just replace while you're in there?

Anything else anyone can think of?
Anything in that list I can expect to reuse off my motor to save cash if need be?

3x crank pully washers
2x cam washers
thrust washer
crank pully seal
Crank flywheel seal
16x valve stem seal
32x valve locks (optional)
5x flywheel bolts
Oil pickup o-ring (optional)
Oil pickup (optional)
Oil strainer (recommended)
Oil pump (recommended)
Oil chain
oil chain guide(s?)
Timing chain
timing guides (2 different ones)
Timing tensioner
Dcr vvt (recommended)
Cometec/oem head gasket

Injector seals (recommended)
Injector stud kit (optional)
Pcv


Maybe more im not thinking of, im tired.

That gasket kit is nice. I've used the OE head gasket without issue. The one thing that kit doesn't come with is a rear main seal. [part #'s listed in the "build sheet" thread.]

Clearances depend on what you want to do with the engine - i.e. 100% street car vs 100% drag car, they will be set up differently

Main bearings - 5, but one is a thrust. Change them (I would never reuse bearings in a performance engine).

Bearings, in general, should NOT be ordered until you know what size you need. I just have my machinist order the bearings, and it works out fine. I found out Clevite makes bearings for us this way

I don't order pistons until I know what size I need, unless it's a brand new block. No sense in boring it if it will clean up at standard.

You can reuse a LOT of stuff from your old engine if you want to. The "must replace" items are the crank friction washers, crank pulley bolt, and cam friction washers.

Beyond that, the "optional, but recommended" things I consider are: oil pump, water pump, timing chain (may be "must replace" if stretched), oil pump chain, VVT (DCR or PTP).

I don't order a lot of stuff until my machinist tells me I need to. Valve seals are covered in the kit (and should be replaced), but the valves/springs/retainers shouldn't be ordered unless you need them or want to go aftermarket. A lot of this stuff really depends on what you want to do with the engine.
