Pulley kit already out there for FC3S

I would be interested in a kit that comes with a main, alt, and water pump pulley.
I also think the factory turbo to T4 manifold adapter is a good idea.
As is the turbo backing plate flange, so bellmouth or divorced downpipes could be made.

how about a ribbed belt kit like the fd used? i mean, WHAT car actually uses a V belt anymore?
jp2la, the pullies look awesome, but still have the problems that the V belts ALWAYS had and ALWAYS will have.......... i converted my 1970 bug to a ribbed belt for a number of reasons, and never looked back
ribbed belt kit for the fc ftw!!!

Do mean ribbed like a serpentine or ribbed like a timing belt?

a serpentine belt is a design, a ribbed belt is what they are called, vs a cogged belt is a gilmer drive..............
examples: ribbed belt- a belt that has ribs running the length of the belt, allows for close to noiseless operation, all modern vehicles use this style belt for their serpentine system
cog belt: a belt that has individual cogs running lateral to the belt, usually used for timing systems where a belt is present (instead of a chain style), also used for a traditional roots style super charger
so no, i meant a ribbed belt conversion, not a cog style belt.............

But that requires the use of an FD alternator and does not come with a main pulley.
I would be interested in a kit that comes with a main, alt, and water pump pulley.
I also think the factory turbo to T4 manifold adapter is a good idea.
As is the turbo backing plate flange, so bellmouth or divorced downpipes could be made.

Yes, my alternator pulley is made for 100amp alternator upgrade, the stock S4 and S5 alternators are junk...Why not upgrade?? The FD alternator is not even exspensive..

I am offering the 5 pulley ket for $385.00 shipped.. Made in America with high qualty material, flawless design, CNC machined, and then anodized...
You can not make the kit here in the USA and sell it for less...Tiny profit of these... not even worth talking about and I have yet to sell even 25 kits yet.. and I made enough parts to assemble 100 kits..
Huge chuck of money invested... Surely I will die with them... unless I decide to sell them off at a huge loss..which aint gonna happen

Why is everyone chasing bigger throttle bodies? And especially, on the stock manifold?
If the TPS is the only issue, CNC a bracket that allows a typical Ford or GM style TPS to be mounted.
Slapping on any single blade throttle body is going to cause more headaches in the tuning department than a flaky TPS ever would. And I will guarantee that you will never quite get that low load transition from idle to high throttle just right. Plus, it will completely kill runner and port velocity in the primary ports. You'll need about another 0.5 - 1mS of injector time to compensate. Also about 50% more accel pump.
All Mazda rotarys have used a staged throttle system since the '60s for a reason.

lol I kid I kid. I hope the project is going well.
You make a great point Aaron. I think a single bore TB would still be useful in high HP applications. I would love to hear input from YOU as far as what you think might be a good idea for design. Also, what do you think of the water pump plate to allow a remote pump to be used?
Keep the ideas and discussion coming! I'm hoping that my brother will be able to run a 4th axis rotary table as well. Send some FB/FD guys this way too! Any mods have any words about cross posting this into the FB/FD sections?

Carb manifold adapters sound cool but that's starting to get into ROI questions as far as design work and setup goes. I can't imagine too many people would be interested in running a carb on an RE or REW ... maybe ... but I have my doubts.
My plan is, once everything is setup and ready to go, to start hitting up all the different car forums. I would be starting with the ones I have the most experience with and moving on (240/SR20, BMW, Mustang, ect. ect.), trying to find ideas for products that would produce a reasonable ROI (return on investment) while being able to maintain a low price. I started here to get a feel for how it might go and for starter ideas ... considering I'M FCGUY!!
Most of us car guys doing work in our own garages are pretty frugal folks so whatever products people come up with have to be reasonably cheap both in production effort, material, and final retail price. Also, I'm trying to avoid solutions that are already available ... it's not really the plan to try and compete or move in on anyone else's established business. There may be some exceptions. For instance CNC porting of irons ... lets say it's only available on the east coast and shipping is pretty bad to get all 3 irons there. That's just an idea out of my ***.
No promises here people ... still negotiating on even getting the machine but let me thank you guys for all the input so far. It's promising to see the ideas come out and gives me confidence that some extra money can be made making needed parts for RX7 owners and much more (with any luck).
Keep ideas coming ... keep discussing said ideas ... and if you can please provide links to items that are currently in production/sold that are mentioned in this thread.

- only that these adapters are avail for 6 and 4 port FC engines- only-
and they run hot as installs into s1, 2, 3 rx7 and earlier rx's
where the user just donates his carb and manifold and timing cover and dizzy
( and extractors )
there is a huge hole for someone to make the equivs for RE, REW and for the rx8 engines
so they become easier choices for carb retrofits into the cars produced before the mid 80's
- FC engines are now getting thin on ground and someone will do it
- even if you don't
whoever does them first and makes them avail at reasonable cost will corner a LOT of sales

How about a whole line of aluminum intake manifold flanges for all the 13Bs for those who make intakes? Very easy to design and cut out, and easy to make cheap. Not high volume though.
A bracket allowing a modern TPS to be used on the stock throttle body.
Billett Haltech mounts?

I have what is likely the flu, and have had nothing to do all week but read the forum in between the few minutes here and there I could actually concentrate enough to perform my day job.
Don't bother recreateing parts that already exist unless you can do it better and cheaper. Water pump adapters have been done.

Since no one has said it I want a NICE s5 LIM to FD UIM adapter plate much like the one that japan2la had for sale that he had. It had 2 separate plates so each plate bolts to each manifold independently that way no modifications to the manifolds need to be made.
