Things you would recomend while building a motor?
Hey guys I'm about to get started building a motor and I was wondering what little projects I should do while I'm building up the motor. Some of the things I'm already going to do is remove the FPD, street port, and remove the air pump and replace with a idler pulley. This is all I can think of at the moment. I'm keeping the motor basically stock for now till I can afford a new intercooler then I already have a gt 40 turbo and a new fuel system. Any help would be much appreciated.

When your engine is out it is a good time to:
Upgrade the clutch and flywheel, it save you a bunch of labor later. With a GT40 you are going to need a good clutch.
Upgrade the radiator, AST and hoses
Install an oil pan brace
Clean and flow test your current injectors since they are going back in for the interim
Vacuum line replacement and/or simplification with BOP kit, to get you ready for your single conversion.

^Replace fuel Pulsation Damper or delete ala Banzai's instructions
*Clean and re-wrap engine harness
*Replace plug wires and coil harness
*Replace OEM OMP lines with stainless.
*Thrust bearing and washer
*Pilot bearing and dust seal.
*New clutch fork and throw-out bearing
*New rear transmission seal
*If you keep the OEM flywheel, it's a good time to have it re-surfaced.

Also, try not to get too carried away. Having the motor out you can get into a world of small projects to improve things - there's literally no end to the money and time you can toss in at this point. Be reasonable and get the car back up and running.
I've seen many cars go from a blown engine to sitting rusting in the backyard due to creeping featuritis. Stay reasonable with it, set goals and a budget as well as a timeline, and get the car back on the road.

I removed everything in the bay, cleaned it 3x, sanded, cleaned again, sanded, rinsed, dried and layed 3x coats of chassis paint on my engine bay. made a world of difference and actually gave me a sense of pride I previously didn't have in my project. I would also reccomend a buffing wheel and green rock compound, then go to town polishing parts.

I would like to thank everyone for their comments.
I completed my nerve racking rebuild (my first one) and I did a complete rebuild new seals everywhere and I got RA super seals and springs. I replaced the stationary gears with rx8 ones as they were cheaper than new FD ones and they are an upgrade. I did full emissions removal as well as the thermowax and FPD. For the Thermowax I pulled out the coolent nipples and taped the holes and put plugs in(If anybody wants I'll do a write up on this). I replaced the OMP lines with stainless steal ones and added the omp adapter. I did replace the turbo coolant lines. And that is all I can think of right now.
Please keep the comments coming for future peoples builds.

Nice thread, I am pulling my motor out and overwhelmed with cracked wiring harness, brittle connectors, brittle tabs, hardened hoses, engine bay rust, rusty fasteners, worn out a/c compressor, etc, etc!! Think the engine bay was originally painted with the factory base coat clear coat? Looks that way in certain spots.

Now would be a good time to upgrade your clutch/flywheel/motor mounts. A new oil pan is almost a must to avoid leaks, flattening out the old one is a crap shoot. If your throwout bearing is original or making noise, replace it. Original clutch fork and installing a stiff pressure plate? Consider buying the new upgraded unit from Mazda. They can (and will) break. I've seen it many times.
Lots of people forget to replace things like the rear main seal, rear stat gear sealing ring, and the pilot bearing & dust seal.
Internally, there are so many little things--- proper clearancing of seals, thermal pellet in the e-shaft, oil mods, checking that the squirters on the e-shaft are tight (most aren't), spec'ing the metal control rings (most are worn out), checking rotor weights, checking and replacing bearings, checking and replacing the oil pump and chain etc etc.
Also the original throttle cable and hood release cable seem to be reaching the end of their life in most FDs I've seen..... not a bad idea to swap them out before you have an issue (motor in the bay or not).

Also, do NOT forget to flush your WHOLE oiling system including, but not limited to, the oil cooler(s). Also, I would recommend buying a NEW engine harness rather than just "retaping" it.
