sequential gearbox for FD3 racer
 

Anyone?
brand,impression,cost.......

Quaife was fairly popular a few years ago. They are out of England. I looked at them in 2000 and was impressed. I am too lazy to search for the website.

id like to know about this too so i can have ideas when i get around to building the race car

HKS and Greddy both used to have 6-Speed as well as sequential gear boxes available a few years ago. It might be worth sending an email to both of them to see if they are still available.

I don't think I wouldn't bother talking with HKSUSA as they probably don't know anything. I would contact HKS Japan.

thanks....
I find this company in Australia www.holinger.com.au
they have one,the RD6 with adaptor for the 13b and 20b...
waiting for info from their USA importer...

Giampiero, let us know what you find out about from the US importer. I am curious as they look to have decent gear boxes. I would really like a sequential dogring setup that I can call out my own ratios. Stock ratios are good for stock torque curves, but not for big singles :(

For the low budget sequential shift action...I love the Ikeya Formula version...this is the best I have seen of it in operation. Suppposedly they used to chunk the shit out of transmissions, but now are much better. This is some crazy drift action, but the shifter is sick. It bolts onto factory trannys, but has the pull back upshift, push forward downshift action. Only seen 'em for Turbo II or FD trannys.

I have one,but its not on the car as yet.....
I will installed it soon ,but what I really want is a sequemtial 6 speed......

so is this clutchless? throttle interrupt maybe?

Ikeya is not clutchless (unless you don't care about your transmission :) ).

exactly:rlaugh:

Check with these guys.

nice link,thanks

Xtrack, Hollinger, Quieffe, Hewland, Gertragg all make seq, shift trans. Cheep alterative would be a Jerico with a sequential shift adapter.

Xtrac,Holinger,Quaife,Hewland,Getrag............

are any of these clutchless?

R magic has one, i am sure panspeed makes one too.

any ideas on cost for a clutchless sequential system? (gearbox and shifter)

ithink it was like 10K and +

By clutchless due you mean Dog ring? if so proper race boxes such as xtrac,emco,hewland.... will run $15,000+

and that silly bolt on shifter for the stock gearbox......are you serious? whats the point of a sequential shifter on a syncro box???

8-10K for a good, dog ring sequential gear box. I looked a bit into the Saenz boxes as they seemed a good value. The best cheaper option is probably the G-force T-5 Dog ring gear set. It isn't sequential, but the ratios map over to a road race car pretty good. For $3000 it seems pretty solid.

T5 tranny to Mazda bellhousing adapters.

The G-Force isn't a 1:1 5th, but hey, for the savings you can always just run a different rear end gear to make up the difference.

You can sometimes find a used Jerico from one of the roundy round stock car guys for a reasonable price. Everything else is super expensive.

I have a friend with a T-5 dog box in his 240SX. He said it was way cheaper to go that route than to get a set of dog gears for his Nissan transmission. I'd suspect the same is true for the Mazda transmissions.

OS giken make really nice ones also

the GT-R's use them in drag alot ..

called OS-88 Version 2

DID not get a reply from the importer as yet(sent e-mail the 12th of October);But I found out from a friend in Australia the cost with the adapator.......approx $22,000 US$:shocking: ,honestly I thought much less.

$22k is a ton of cash. My budget it half that, at the most :(

I'll sell ya a Hewland ST 5 speed (non sequential/no clutch) dog box, with a drop
gear, and many (25) gear sets, dog rings, shift forks, and other spares. With the flywheel, 4 1/2" clutch, and bellhousing for $23K (less than the cost of new).
Oh yea, I'll throw in the rest of the car for free.

A real sequential racing gear box is going to cost serious money. $22,000 is not out of line for the cost for a sequential box; X-Trac will cost $50,000. Trying to save money by buying a used racing gear box is always a risky proposition, unless you include the cost of immediately rebuilding it in your budget. If you really want speed for your car - then the money should be spent elsewhere on your car. Most racers are happy just making the jump from a street transmission to a heavy duty racing dog ring un-synchronized tranny - which are great for racing and horrible for street use.

I was just looking at the G-Force site yesterday. They list the GF5R with a V-gate shifter ('merican for sequential) for around $6000-$7000. They even list adapter plates at the botteom of the page for $350 for Turbo II, $550 for 3rd gen. Probably the cheapest option for a solid road race box available.

Isn't a V-gate for upshifts only (more or less) and basically only good for drag racing?

Hard to say from their site:
http://www.gforcetransmissions.com/shifter_5_vn1000.asp

specifically the line: "Push-pull design virtually eliminates missed shifts."

$$$:shocking: $$$

Any other companies?

I'm pretty sure it's set up so that you just push and pull it back and forth to upshift and you have to pull the handle up or something to downshift, so it'll be hard to use in road racing.

I use a GF-5R with an H-gate shifter in my peripheral ported 13B road racer. Total cost of tranny with Magnesium case, the shifter and all the adapters, and custom driveshift and yokes ended up costing about $6500 several years ago. This thing is bullet proof, it was built to withstand big block V-8 engine drag racing. The upshifts are lightning fast; the faster you pull the shifter, the smoother and faster it shifts. Down shifting a dog ring box is tricky; whether sequential or not you will hear some crunching if the revs are not closely matched. This tranny is big - you will probably have to widen your tunnel for it like I did on my first gen. Since I put that tranny in a few years ago, I have not lost a road race because of transmission problems.

I believe the V-gate shifter is setup for drag racing up shifting only; that is why I use the horizontal gate shifter for road racing. The Long shifters (which is G-Force parent company) are one of the top favorite Nascar shifters, the Long shifter is even on Jerrico trannys.

If you are cheap and just want to brag that you have a sequential shifter, then get yourself a motorcycle :)

Saenz Performance out of Florida

Pfitzner Performance Gear sets is a place that I am going to order my dogbox. It is not sequential though. My friend has their drift/drag gear sets for his s13.5. The gears are amazing.

saenz boxx
 

would u sell your saenz box

Yes.

Pull back to 2nd

Push forward to 3rd

Pull back to 4th

You just don't have to go side-side.

Definitely NOT a sequential.

i know this was an old thread, but in case anyone is still trolling around:

https://www.rx7club.com/showthread.p...ht=dt-5+damian

U guys can have a look at http://www.libertysgears.com/

They do sell sequential gearboxes and normal dogboxes. I just orderd there modified Tremec TKO600 dogbox. That will suit my needs more then enough.

U also have a company called sellholm in sweden that makes sequential gearboxes that fit the FD bellhousing. They are about 12 0000 USD with todays exchange rate.

sorry,its already sold.....

Which Saenz Box was it? The 840 seems a little small for a turbo setup.

The cheapest sequential option I've seen so far is probably this:

or if you have a little less power, this one:

Ikeya Formula Sequential Shifter
 

Ikeya Formula Sequential Shifter
just wondering if anyone has one installed on fd

or install pic


The Ikeya Formula sequential shifter converts conventional H-pattern shift to a sequential up and down shift mechanism. The clutch is still required, but the movement is dramatically simplified.
