This will be as short as I can keep it,

1. Installation of a Magpul MOE PTS Motor Grip, Compatible?
2. Plug-n-play FET room in crane stock
3. 14mm negative threads, right?
4. I will eventually want to install a better bucking, The PDI W Hold
5. Possible VLTOR metal body?
6. Tienly GT - 40000 RPM Ultra Torque Performance AEG Motor (Long) Able to fit in said motor grip?

I'm going for a high-rof build, any internals possibly interchangeable I would like for you to recommend any parts, thanks.

Grip fits, Plug n play mosfet should be hardwired or its mainly going to control the burst.
I was unable to fit the W hold in a KWA, great bucking in my other AEGs
Are you having problems with KWAs bucking?

Motor sounds good, i have the Tienly GT-45000 little more money, comes with heat-sinks & fits in grip.
I like the 35000 solid motor, not the best choice for high ROF, both are well made AEG motors
11.1V battery?

Sorry, Cant help with the spring & piston.

The only item on your list that will increase ROF is the motor. And there are motors with higher RPMs on the market. ex. Tinelly 45000, SHS HS is said to run around 48000 RPMs don't know how they checked that.

Whats your ROF goal & where is it now?

To add on to what Tales has written, the 14mm CCW is correct, and a KWA will not  VLTOR lower as a drop in mod for a whole host of reasons.

Currently, the rof is about 15-20 bbps. My target rof is about 30 bbps build, Thank you both for the answers. I chose to only use my 11.1 some times because of the increased wear and tear it can cause compared to a 7.4 or 9.6.
Do you guys know of any heat sinks for the Magpul PTS MOE Motor Grip?
Can a hunter Seeker Army r-hop fit?
Thanks

Sorry, what do you mean by heat sinks  for the motor grip. The only part of the pistol grip that comes in contact with the motor is the plate.

It rests on the end bell, thats made of plastic. Plastic doesn't conduct heat, it insulates heat. Pistol grip is a poor environment for a motor.
Heat sinks if any should go on the end bell
Tienly 45000 comes with a set of orange heat sinks, on the right.

I'm not sure what exactly I was talking about, I was reading about upgrades done to a guy's SR7 and he installed a new plate at the bottom of his MOE pistol grip for more ventilation, I think.
But, I don't think I need any kind of thing like this.
Thanks for the pictures, they helped!

Those are heat sinks, They draw the heat from the end bell saving the brushes & other motor parts. Venting will help but it won't remove most of  the heat the motor is causing.
I tested a few motors and some aren't efficient at all, and get hot. Tienly  & Lonex are hand wound and run cooler. Tienly has a vented can, a plus for removing heat from the motor.

There is another Magpul plate, i think it changes the motors angle. gcw uses that plate he could tell you more about it.

Stock Magpul plate, not much room for more ventilation holes

Even the heat sinks i posted aren't that important, if you maintain the motor. (Airflow is the best choice, none in the grip)

I dont understand how it could be a heat sink. it should only contact the plastid end bell, and plastic doesn't conduct/transfer heat.
Thats why pan handles are made of plastic.

"Upgrade"
I can't comment on that,  never seen one, i won't buy it.

My son and I both use the Magpul upgraded metal end plate.  For me it's a great upgrade that ensures proper motor angle and height.  Without it I have needed to modify the stock motor end plate to get the motor alignment the way I want it.  If you can find one I recommend it. Note: Just as Tales commented, it shouldn't do anything as far as improved heat dissipation.

Can you link to the one you are looking at?

Ok, but the one I was looking at is discontinued, so I would have needed to find a product someone else bought previously. I'm not sure what this "heat sink" will do though

That's the part but forget about "heat sink" it's just how someone decided to list it at Evike.  If you can find a used one I would buy it.

Do any of you know if www.365airsoftshop.com is a reliable retailer?
I want to order a X3-2 Replica Eotech, m910b LED Surefire, a Eotech magnifier and a rmy Uniform Multicam.
I'm only slightly suspicious and worried.
Thanks.

Edit/add on:
These will go into my sr7:
