Hey I’ve been using this forum as a search engine for years. I had an ‘84 fb in college, did some work on it back in 2013-2014 and life happened quick. Married, kids, house, new state everything.

fast forward to today and I recently picked up an ‘85 GS with an old Elford Turbo body kit (minus the front bumper) in the V3 Tender blue.
215k Miles!

Pretty much my dream rx7.

It needed some obvious basic maintenance, and I’ve been going through everything I can easily, and bring the kiddos along for help when they are into it.

Just as a first post I thought it would be good to go through some things I’ve been up to, things coming up, and things I need help with.

Recently I just did the following:

- major cleaning, interior, exterior, engine bay clean up, degrease and overall cleanliness
- cleaned the heater blower (entire forest was in there)
- NGK spark plugs, NGK wires, rotor and cap
- 15” Kamei K1’s wheels
- 205/50/15 Khumo Ecsta PS31 tires
- new to the car driveshaft
- pitman and idler arm
- 20w50 conventional oil / Mazda OEM filter
- Idemitsu premix .5oz per gallon (no clue if the OMP works)
- air filter
- changed the cloth fusable links to the modern Bussman style
-Removed the subzero assist unit
- Door card removed and copy cat of techno toys style cards.
-Pioneer head unit and front speaker upgrade


Parts in the garage waiting to be installed:

- Racing Beat Spring set
- Full Energy Suspension bushing package
- KYB Excel-G front shock cartridges
- KYB AGX rear adjustable shocks(previous forum member had a write up on these to just cut the mounting eye down 1/4”)
- Upper Strut Mounts
- Front lower ball joint
- Inner front tie rods
- All new engine belts
- Racing Beat Radiator hoses
- Aluminum 3 row radiator
- Thermostat/gasket


Things I’m waiting on to start the above, have questions on, or just need help:

- When I slowly hit the gas from idle to about 3/3.5k i get these dips downwards like the needle shutters for a second then if i give it more gas it keeps climbing. If I mash the gas this is mostly unnoticeable, it’s only when I’m slowly pressing the gas. This is also only been noticed in my driveway(haven’t checked it while moving yet, or noticed it)

- My radiator clutch fan is probably seized? (It follows engine rpm at all times)
***Do you just replace it with a new one, does it have any sensors, or just simple remove and replace?***

- My headlights flip up and down with the left toggle button, and with the stalk.
The “push forward and stay on brights, don’t work”
The low Beams work 5% of the time randomly mostly don’t work at all.
The high beam flash to pass always work.
**any insight on what I can do here?**
***seriously thinking about getting some halos and just wiring an independent 4-way switch to make them (DLR On/ Lows On/Highs On/ Off)
** would I need to upgrade my alternator? **

- My A/C dosent work, I want to just delete this for now as i don’t know if it’s the compressor or a leak somewhere? Seems straightforward to delete. Will tackle this when I do the coolant system.

- I’d like to do the Racing Beat Road Race system, and delete the air pump.
*** do i need extra block offs from RB or does it come with everything?***
*** do i need to upgrade to a dual pulley on the alternator?***

- WHEN the engine goes, I think I’d want to do a street ported 12a, or Bridge ported 12a. Unless someone can convince me of a 13b street port w/ carb swap, I just want it as close to plug and play from the 12a and rather not mess with an ECU and tuning.
(I know this will come with the need for a new carb setup, fuel pump, regulator, filter etc)

That’s all I can think of right now!
Any help to these issues would be appreciated. I’ve been searching most of this on the forum and these are just some questions I couldn’t find clear answers on.

 

Welcome to forum , Sweet ride you have there

 

Welcome to the forum!! That's a gorgeous 85 GS! I love everything that's been done to the car and the color is one of my favorites! What kind of condition is the interior in?

As far as the small nuances, we can help you in the 1st Gen tech section.

 

Beautiful car! For your headlight issue that seems like a combination switch issue. I have the same problem when I push my brights on to stay on they go out. You can buy used combination switches but they are a bit expensive and I don't want to break any brittle plastic installing one haha. I also recommend a duel pulley on the alternator. I have yet to buy one but keep getting recommended by everyone I know to get one. Will probably order one this summer... I also have an air pump delete on my car paired with a RB header and exhaust but the setup may be a bit different as its a GSL-SE...
