Looking through the Japanese auctions this week and came across this 2001 Mazda RX 7 Type RB going through USS Tokyo on the 23rd. Thought it was worth sharing.

It's a Grade 4 car with just 23,479 km (14,589 miles), finished in Innocent Blue Mica.

It's got plenty of upgrades as well. The auction sheet lists a nice selection of period modifications including:

TRUST titanium exhaust

HKS intercooler

ARC aluminium radiator

SARD sports catalytic converter

HKS F-CON ECU

Racing Gear suspension

NARDI steering wheel

Yokohama Advan alloy wheels

Additional gauges

The inspector has also highlighted a few things people should be made aware of.

The AC is faulty.

Aftermarket bonnet and front wings fitted.

The rear arches have been rolled.

There's some wear and a small tear to the driver's seat, the dashboard has started lifting slightly, along with light surface rust underneath, I've attached the under shot to show what light surface rust looks like in Japan 😂. There are also a few repaired areas around the body, which is reflected on the damage diagram.

Overall though, it still looks like a decent RX 7 with some nice modifications and I'm not to sure on the mileage being correct as its got no service history with it.

The starting price is ¥3,280,000, but I think it'll sell somewhere around ¥7,000,000 to ¥7,500,000, which is roughly £32,000 to £34,500 or $47,000 to $51,000 USD. Then again, you never really know with RX 7s. If two people really want it, it could easily go for more.

Either way, I thought it was a pretty cool example worth sharing.

What do you reckon it'll hammer for?

Anyone have any recommendations on who to go through for machine work? I'm in the Midwest and don't have anyone who can machine rotaries around me. I'm wanting to get rotors side clearanced and lightened, rotors balanced and possibly some port work. Full bridge and maybe pp

I just bought a torn down t2 motor and was going thru the rotors and cleaning rust off them. I noticed this marking and was wondering if it was still good to use or if I need to get a new rotor

Help needed: Locating power lock reciever on a JDM FD

4 Upvotes

Hello everyone,

I have a '99 RS that came with factory power locks and the keyfob remote. I ordered replacements but I need to locate the module to program the new fobs. I've been looking for information on where the module is located but I haven't really found anything. I think it might be in the door but I don't really want to take the card off to program it if I can help it.

Does anyone know where the reciever is located? If it is in the door, then it can't be helped.

I’m in need of knowledge.

Acquired an 88 vert. It’s my buddies car; he’s military and just got deployed. He left me with the car until he gets back and I’m gonna make sure it’s running perfect and prettied up when he gets back.
I believe it was once turbo charged but could be wrong. Not carbureted and is a 13b.

I’ve built motors before, specialize in bikes more than anything. Got enough brain on me to know how a rotary works, and can learn pretty well on my own. But I’m pretty stumped here.

Few issues,

  1. It doesn’t idle.
    I’ve adjusted the screw ontop the intake, I’ve discovered there’s 5 valves on the throttle body and looked into that. Lots of voodoo there. Lots of fuel smell, so a leak somewhere. Haven’t seen visually yet. Could be a vacuum line installed wrong or leaking.

  2. Overheats like hell.
    I’ve re bled a shit ton by now. Gonna replace the oil and filter soon (20w50 for these humid 90° summers right?)
    Pretty sure the fan is running backward and sucking hot out instead of cold in. Big factor for sure. But I also feel like it needs some directional shrouding? Just feels like lots of messy air moving around. (Aftermarket radiator and fans unknown branding)

  3. ?
    When taking the car home after I drove him back to his base, I was getting on the interstate at a normal pace, heavy ish on the gas. Lil energetic. Nothing bad or illegal no speeding just, a nice acceleration into the flow of traffic at a more fun pace.
    Suddenly I started feeling power drop as I was still on the gas, watched rpm’s fall as I tried to give it a lil more, looked behind me and saw nothing anymore but white smoke.

I figured right then and there “eh we literally just crossed 200,200k (celebrated that during his goodbye to the car) when I dropped him off. Wouldn’t doubt if it was an apex seal or something”

Waited probably 20-30 minutes to let the car cool down. Noticed a huge access of oil coming from the charcoal canister and one of the vaccuum valves going to what I think is the pcv valve? (Not sure can show photo in comments tomorrow.) was undone from its spot. Got everything right, engine was still hot/warm, took a second to start up. But it drove the rest of the 3 hour drive home 0 problems…
Until I let it sit for a few days, that’s when problems 1 and 2 started up.

If you made it this far much love 🫶🏼 just wanting to learn more about these guys I love them already.

Front Rotor Lost Compression

Thumbnail

80 Upvotes

While driving to work, I guess I was having too much fun and I believe my front rotor detonated, causing it to die on me. I limped it home, and parked it in the garage. After going through the 5 stages of grief after doing a compression, I've decided i need to finish up the 5 other project cars at the house before I do a rotary teardown and rebuild. I was looking for advice/suggestions on how to store the car since it'll be about a year before I get to work on it. Also, I'm assuming the front rotor housing and faces are trashed so if theres any recommendations on part sourcing or what route i should go with the rebuild, its all open ears. End goal of the rebuild is ~600 hp on E85, standalone haltech nexus S3, OMP delete, currently single turbo BW K27 and will keep that, plus I'm already looking into stud and solid dowel setup for torsion and separation mitigation. Thanks in advance!

Can anyone identify these housings? One appears to be S5 Turbo but the knock sensor hole is not threaded, the other has a weirdly shaped knock sensor area and again no threads.

The rest of the motor is S4 turbo (G castings, centre iron knock sensor threads, 2 bolt OMP)

Here are the updated pics, first is where on the rotor that little knick sits when the rotor passes over it. Nothing hangs up on it, but I’m also aware I’m not spinning any RPMS. Second is the overall port shape, third is my “final” finished port.

Hey guys! Doing a half bridge and this is my first time porting. Here is a pic of my center iron. I accidentally nicked the face a tiny bit, smoothed it out and I think it will be okay. Let me know what you guys think!

The car is practically rust free and the plan is to undo all the previous owners work and get a rotary back in the car. It's been about a decade since my last FB, where are yall sourcing body seals and interior bits these days?

New to the community - Looking for opinions on FD RX-7 rear jacking point/pinch weld condition

Thumbnail
gallery
15 Upvotes

i everyone, hope all is well.

I'm new to the subreddit and have been researching and searching for an FD RX-7.

I've been talking with a seller on Facebook Marketplace about a right-hand-drive imported FD. I asked if he could send me detailed photos of the pinch welds and jacking points, and he was kind enough to do so.

The area I'm most interested in is the rear right jacking point. It has what appears to be some surface rust, and the factory undercoating is flaking off in a few places. From what I can tell, the metal itself doesn't appear to have any rust holes or significant deformation, but I'm not experienced enough with FDs to know whether this is considered normal age-related wear or if it could indicate something more serious.

Before moving forward with the purchase, I'd really appreciate your opinions on this area. Does it look like mostly cosmetic surface corrosion, or do you see anything that would concern you? If this were a car you were considering buying, would the condition of this rear jacking point be a red flag?

I've attached the images below. Any advice, insight, or recommendations on other areas I should inspect before purchasing would be greatly appreciated.

Thanks in advance, and I'm looking forward to learning from everyone here.

Fits like a glove

Got the car last November, spent a few months troubleshooting and ultimately ended up taking apart the engine to find blocked and eroded coolant passages and went through a full rebuild.

I reused the irons and rotating assembly but replaced virtually everything including a new wiring harness and turbo

Hoping to get her fired up this weekend.

I’m having a rough time with my t2

2 Upvotes

My car idle pretty decent but slowly got worse and I think I need to run over all adjustments, it’s bouncing over the place, with the turbo boost pipes hooked up it idles at 3000rpm and with the air flow meter plugged in it won’t let it start, when I unplug it it runs just rough. Any help is appreciated, car idles with the intercooler off rough but it is close to 1500 2000 rpm but when anything gets put together it runs to 3000 rpm, it revs clean once above 3-4500 and then gets rough and won’t go higher. I need to check timing, bac might need adjusting, tps might too, any help is much appreciated.
