Happy new year, bonne année 2025 !

First update of the year

I previously order all internal parts of my engines on jdmplanet but after 3 mouth with no updates at all, I asked PayPal to refund me. So be aware jdmplanet can take a long long time to ship your part. Aaand I didn’t order my cancelled parts, I will do it soon.

I’ve received my new fuel pump, Walbro Hellcat and my new injectors, Bosch 2x1400cc 2x1050cc, flow matched.


Old vs New

Hellcat pump

Fuel rail convert to AN6

Weird goo on the stock fuel pump

 

Cool build, glad to see you are still cranking on this. How's the motor going?

 

Why do a 4 lug conversion from 5 lug?. . .

 

This was answered already... I think. Those awesome wheel it came with are four bolt.
Also some prefer the four lug setup as the selection of vintage wheels or other is better.

 

I believe that he mentioned that the parts ordered were never delivered so .... I assume no progress.

 

I see. . .previous parts. . .Sorry, late to the post.

I see the rear flared fenders now.

As a 4 lug owner, I always wanted the braking performance of the 5 lug setup.

 

RHDJapan should be back this week, so i'm gonna (i hope) order this week !

I'm still using the bigger brake, redrilled disc.

Lesgo !








A friend of mine give me for free some RX8 tension bolt. Nice free upgrade ! (Turblown stud kit is a bit overkill for my power goal)

stay updated !

 

Feb update








My first time doing a rebuild, it was pretty straightforward. Except maybe side seal clearance. I’ve messed up my first side, I trim them by hand and I didn’t had the right angle… doing it with drill should be easier and better.

Shaft is turning freely with no hard point at all. You can ear all 6 comps

I’ve put too much assembly lube, it was a mess haha.

Next thing is to order the last bit for the fuel system (fittings and fuel line).

Money pit project but I love it !

 

April update :


Fuel tank need a good clean !

AN6 stock fuel rail. Sandblasting + powder coating make life sooo much easier and cleaner




Old housing. Holding my RX-7 books

After sandblasting



Before




Scored this FD intake. Please. Don’t put the ugly FC… I hate it

New brakes discs converted to 4x114.3

 

This bad boy is now sitting in the bay !

I’ve struggle removing the old pilot bearing (2hours), using dremel seems to be the way to go !

@j9fd3s quick question : I’ve got super now solid engine mount. I checked and I ordered 46mm height one. Since I’ve got the thick sump baffle plate didn’t I need shorten one like you said on a previous reply here ? I don’t know the stock height…

I’ve got a little screw on 1 face of each super now mount. Don’t know if it need to be on top or lower when mounted… I will check later.

 

i thought there were 46mm mounts, and -10mm or 36mm mounts, but i don't see the shorter ones?
it also turns out that the Super Now! stuff is based on something else, and that one machined the aluminum engine mount arm.
or maybe its fine?

 

so they both 46mm

after checking on their website (very hard to understand because Japanese only).
Super Now say : you need to remove 10mm to 1 engine mount.

I will try to find someone locally who can do it

thanks for your reply !

 

I didn't know but 1 kit = 1 pair of caliper




Pitting from rust

I lightly sandblasted the upper part to remove rust

OEM Mazda rebuild kit


This one is the second pair, previous owner said to me he rebuild it. Yeah for sure, you just paint on rust....


Sandblasting time, only the exterior

Current situation

 

Bunch of photos

Engine is now sitting in his bay.

last pic is the left engine solid mount with 10mm removed, 5mm on each faces.

Now, I need to finish rebuilding calipers and after I hope I will work on the differential.

 

I can't help but be impressed. I don't feel quite so intimidated with my own "restoration".

 

[img alt="Front brakes are now fitted. But I need a spacer behind the rotor. I think 4 lug hub a deeper compare to 5 lugs. When you bolt the rotor it will touch the brake shield but not only touch it’s gonna block it.
Now I know to figure it. Spacer behind the rotor ? Mmm don’t really like the idea. Remove the brake shield ? Easy. Cut the brake shield where it touch ? "]https://cimg1.ibsrv.net/gimg/www.rx7club.com-vbulletin/2000x1504/img_5283_e680a527ed7119ea7fe30b91ca3d53e9ff88b5c3. jpeg[/img]

Front brake are now done. I’ve fitted previous brake pads. I will order new/better one later






Sandblasting is so good. Everything look so clean after it
..

 

Awesome progress so far! Wish I too had room for a blast cabinet!

 

Mine is 40gallon, I've put it in top on one of my workbench.

189€ (219USD), I regret not buying him sooner.

 

Hello,

I'm looking at clutch option. Everybody here seems to like this one : Z65-XTSS from ACT.

I've checked on their website and it say : I'm still using stock flywheel, and I don't see why I need counterweight ?

Oh boy : Price is 821,98€ where US felow is 447€

 

It is possible that the clutch requires a different flywheel.

Otherwise, I don't know.

I will give you a bump for some help.

 

I emailed ACT this morning to ask them.

Answer :

 

Hi,
Août update, +40°c (104F°), i think i will order an AC soon...

I post pic below, i've finish rebuilding my calipers, still need to find new boot for the rear, OEM one seems to be discontinued.
I've also receive my Franklin Performance parts, nice quality and fitment !
I'm gonna order new boot, washer and spring for the gearbox lever.


It was time to rebuild these rear calipers.....

And time to order new return shifter spring
