FC3S first service - any advice appreciated!
Hi guys,
I am in the process of importing a 1991 RX-7 GT-X from Japan.
In preparation for it arriving next month, I have been buying all the things that I might need for the first service.
The car is 100% original with 50,000 km. So hopefully it doesn't need much work to be roadworthy other than a good service.
I am based in Ireland so I have been trying to source everything from websites within the EU to avoid import fees and high shipping costs.
So far I have ordered the following:
Oil = mobil super 1000 15W40 mineral oil.
Oil Filter = OEM mazda filter B6Y1-14-302A
Air Filter = Pipercross performance filter (I would prefer OEM paper filter but I couldn't find it for sale within the EU)
Fuel Filter = https://wankelnation.de/Fuelfilter-RX7-FC (I couldn't find the OEM one for sale but found this one on a german site... It looks like the OEM one but I think its aftermarket)
Spark Plugs = NKG BUR7EQ and NKG BUR9EQ
Coolant = FL22 mazda coolant (I got 10L of the premixed one)
Premix oil = Idemitsu rotary premix
I am just hoping to get some opinions on what I have already ordered and some answers to the following questions:
- What gearbox and diff oil should I get? What drain/fill washer sizes do I need for these? (Apologies if this is already documented somewhere)
- I have never used a performance air filter before. Is there any disadvantages over the OEM paper filters?
- Does the fuel filter I bought look like the right one? I have also heard that there is a filter under the fuel pump but that it could just be cleaned rather than replaced?
- Is there anything else I should change in the first service?
Sorry if this stuff is really simple, this is my first rotary and I am also pretty new to working on my own cars.
Thanks!

Fuel filter looks right, and its a good price too
the drain plug washers for not the engine are 9956-41-800, which is 9956 is a washer, 4 is aluminum (2 is copper), and 18 = 18mm ID
the engine is a 14mm, so 9956-41-400
the shop manual, foxed.ca - /rx7manual/manuals/1989FSM/
has an inspection and maintenance chapter, and you should just follow that. it will seem a little goofy, but it does have you look over the whole car and make sure everything is working like it should
