Just read this thread... man what a mission!

Around half way through you guys got a pricing on the PAR AZ6 Dog Set...www.par-engineering.com... Now with the Aussie dollar dropping below the 80UScent mark you can get the full set for around $5.5k and the 1-4 set for $1k less.

Surely this becomes a viable option given it would be only a little bit more than the 5-speed Quaife upgrade, it's in the stronger 6-speed box and it's a custom dog gearset? Also, if there was a GB on this it would be cheaper again.

 

PAR is not really a viable option at this point. Their production has slowed to a crawl due to a reorganization at the production facility, and it is taking quite a while for anything to be made. We (the place I work) are under contract with them for R35 GT-R gearsets and it's like pulling teeth to get anything, been like that for 18mos. I would not send them any money for anything until they have their act together and can get back to a reasonable timeframe for delivery.

 

Any updates on the T5 swap?

Also interested if there is any update on the 6speed gear set from Emilio?

Trying to figure out my years budget for the track and if it will require just picking up a couple spare 6 speeds just in case.

 

No news. I'm still pushing but the R&D staff has many projects on the list, mine is down that list a bit. I have, on several occasions, offered to pay a deposit for production in advance to them even having drawings. They know we are serious. Any other source I approach with this project is either less flexible with design concepts, a lot more expensive or both. So I'll wait for my spot in line. Meanwhile, OGK will get an MSM AZ-6 and be tuned to keep peak power below 370whp and peak torque below about 270lbs. Uncorked, I think we'll be around 400whp/300lbs.

 

Nothing material. My current plan of action involves a 3.8L V6 donor box (electronic speedo) with a V8 input shaft. Gearing might suck but after the initial testing I will jump to a G-Force set with the proper gearing. Going to cut the bellhousing from a 5-speed and go from there. T5 box and input shaft should be here next week. My street car project will have a high-power map approaching 400wtq so I'm dead serious about a gearbox option that will play nice with that.

 

Would using the removable bell housing from the early automatics be a good place to start an adapter from?

 

I don't think anyone would be wild about the idea of being forced to find a specific Miata auto just to pilfer the bellhousing. I'll proto with the parts I have here and if there's enough interest to warrant putting a swap kit together, we'll probably just cast a bespoke bellhousing.

e:
That too

 

Erm, where's the clutch fork go.

 

Good point, but as an engineer is just means its time to get creative.

 

You sound like someone in manglement, you dont dick around like that, just use a 5 speed bell housing.

 

Going custom, there is little stopping you from using a shaft mounted slave cylinder.
Unless there is something on the transmission front face preventing that solution, extreme machining etc. "Just" make a service opening for the hose+bleeding. And get the right movement, length etc.
The clutch fork per see is not a design element that dictate much, but it's very convenient

 

You type like some sales personnel I deal with. I work for a small family owed company where we have to make due with what we have available to make improvements. But yes, to make you feel better (like a salesmen) I will repeat that you have are correct.

 

If anyone wants to cough up the $18,000 mold charge (and supply the drawings), I can make you a bitchin' transmission case using the pressure casting method.

 

I would be interested in organizing and running a kickstarter...I feel like its something that has a possibility of working. Or probably the only way that would happen.

 

I am a big fan of convenient. The OEM clutch fork works with the OEM TOB which works with the OEM pressure plate which works with the OEM flywheel. The only weak link in the entire OEM system is the slave cylinder, and that can be attributed almost entirely to subpar maintenance habits. I have less than no interest in redesigning that particular wheel, so whatever we come up with will retain the factory hydraulics, factory fork, factory TOB, and factory pressure plate dimensions. The disc will obviously change, but that's it.

 

Has anyone considered the FS5W30A gearbox out of a RWD Skyline? Those things are a dime a dozen. I haven't seen any discussion about it before.

Cheers

 

Garbage gear ratios and they are hard to come by in the US.

 

It's been 3 months and I was just wondering if the picture had changed any?
Thanks for doing this.

 

Meanwhile back in sequential land.

$10k, give or take. Exchange rate is about 1.55 just now, bleh.

 

Not even $10k worth of QBE60G will cure shufflesteering.
