All abs fcs dual stage boosters with slightly larger (15/16") bmcs

 

All sorts of Hondas, Nissans and Subarus have boosters that will work.

 

929s also have a dual stage booster with a 1" bmc that fits

 

Interestingly, the Mazdaspeed parts catalog shows the same booster for all S4 apps (ABS & non-ABS), but shows the dual booster for the S5 turbo (ABS).

Note that clokker is a chronic modder (often a good thing), which you obviously aren't pursuing with this car. Stick with the plug n play booster. Hopefully you have a junkyard nearby to extract a booster from, although my advice remains - unload that rig before it drives you into upgrade hell. i.e. You think it's fast now, just wait until you add a aftermarket turbo. Oh. BTW that means a wategate, custom manifold, front-mount I/C (or worse v-mount), new ECU, and a revamped fuel system including regulator, pump, and injectors. Whoa, why is my bank account empty? RUN away!

 

Yeah, I need to track one down. I don't plan to modify the car but I was interested to learn that people are upgrading their brake boosters.

 

its mostly to run a bigger master cylinder

 

the booster itself isn't actually all that bigger if at all. it's deeper (because it's dual stage), but smaller in diameter.

 

Yes run away indeed!

 

There is zero chance of me getting into a mod loop with this car. I have another car for that which is more fun :-)

 

Wow. The car looks great! How much would you say you've had invested in this thing so far?

 

Way more than I expected in terms of both time and money, but it's worth it to keep a car in this condition on the road.

It's for sale now.

god. that UIM is indeed painful to re and i. i must have done it 15 times at least because something was either pinching or rubbing/not routed right. finally got it just right. got back home. looked at my old engine, then realized the atomizers were for some reason not installed in the primary ports on the new/used engine that's going in. so off it comes again. oh well. at least it was found before i put it back in the hole.

your car looks stunning, bud. you have discipline to be letting it go like that for sure. guess it's all about the journey. GLWS. i'm sure you will release it only to good hands

 

actually i think that is a very reasonable price considering the mileage and condition

 

It's an amazing price. The only thing that sours the palate is knowing how much it was bought for 5 months ago. Makes me wish I could've bought it then

 

If only I had $5200.

 

Thanks guys. Yes, for me it's about the journey with these cars. I really enjoy working on them, but ultimately I only have space for what I have... and the money will just be used to fund the next project (which may very well be a money loser, who knows).

My favorite part is tearing down, cleaning, measuring and rebuilding engines and I was kind of bummed that I didn't get to do that with this one. It runs too well. I drove it to work again today... couldn't resist

 

I'll be sure to let you rebuild my engine when I inevitably blow it up John

There may be some S5 NA rotors and some porting involved

 

Car is sold.

 

Sounds like something someone would say that just had a baby. In a way rx7s are like our babies to some of us rx7 owners.

Got a visit from the new owner a couple weeks back. When he bought the car the reverse switch was a little flaky and I told him I would replace it for him with the Japanese version (no 5th gear switch) when it came in. It came in, so he stopped by and I threw it in for him. Not normally a job I would do on a car that had just been on the freeway for an hour - it was hot! But it worked out.

The guy loves the car - hopefully he keeps it long enough that I can help him rebuild the motor in a few years.

 

The things we do to sell a car.
Is he considering any mods or is he satisfied with the power he's got?

 

I don't know. He seems to love it as it is. It's got a couple extra ponies from the downpipe and RB catback.

I advertised the car as not needing anything because I thought the reverse switch was working, so when he showed up and it had flaked out I thought it was only fair to tell him I'd fix it.

 

I can never reiterate enough my appreciation for help!
You will most definitely see me again, with a case of beer, and anything else when it comes time for a rebuild. This car ain't going nowhere.

Cone : I like it just the way it is. And so does everyone else it seems.
My conversations with curious passer-bys generally go with them asking if anything was done, replying no it was OEM restored with a few needed changes that John did, and then getting an earful on that it needs to stay that way.
Starting to feel guilty just thinking about doing something.

But I do want to start little projects here and there just to get my hands into the engine bay. Especially now in the cold season.

 

Cool plan. Stick with belts & hoses and upgrading worn parts (shocks/struct?) initially.
