I'd love to say Mazda did it to balance the car with just a driver, and they may have, but my Tundra has a similarly angled driveshaft for some reason. It creates a vibration at certain speeds.

 

They angled it at 1* for universal joint life.

 

Zero angles is hard on U-joints. They like smallish equal angles.

 

So when is the SuperMiata Version of the Quaife Conversion kit going to be come available. Just blew up my first 6 speed for the year. Made for a very short Track day last weekend. I Have 5 more thankfully. I should'nt be to upset, it lasted a full year.

 

Haha, never. The number of worldwide Miata owners willing to spend $12k on a transmission kit can be counted on one hand. Beyond that there is no margin whatsoever. Not a small margin, no margin. If you are one of the folks with that kind of budget, I would suggest contacting Hitech in Irvine for a duplicate of the mounts they made for us.

 

Offering a "kit" makes zero sense from a business POV. Emilio was kind enough to share his journey so followers like myself are not going in blind. Props E!

 

Any drive time on the Quaife yet Emilio?

 

Emilio, which lever type did you choose? QGE60G00X where X denotes lever type.

Which Geartronics gear **** load cell did you get? The line one? Geartronics - Sequential gearbox electronic systems - Flatshift Pro . Where did you install it? The geartronics paddleshift system seems heavily overpriced but I suppose it is a niche market.

 

The lever shown in the picture. It is also in the bill of materials for the Miata kit, not sure what the part number is. I contacted geartronics and asked them to send me a shift **** with the correct thread for the lever. That is all I purchased from them, we are not using their Electronics.

 

Thank you Miataturbo for teaching me that **** (k n o b) is a dirty word.

When I clicked through on their page previously, I didn't see it listed in the kits. Looks like it is QBE60G-Maz0X where there is X=1-4 and the variables are helical vs straight cut and double overdrive vs direct / overdrive. I'm assuming dog / straight cut gears for yours. What ratio set did you choose? (direct / overdrive or double overdrive) .

 

Spur, closest ratio set.

 

Thanks! Looks like QBE60G-Maz02 . I see multiple gear sets offered there and then different options on their spec sheet.

These are the gear ratio sets I saw. Is the first one the one you got? The last one I only saw in the spec sheet that didn't seem to be Miata specific.
Spur 2.400 1.840 1.482 1.260 1.104 1.000
Spur 2.240 1.694 1.333 1.150 1.000 0.889
Spur 2.240 1.840 1.482 1.260 1.104 1.000

Yes, I am serious about this gearbox after I go through my existing 6 speeds.

 

2.769 2.057 1.579 1.260 1:1 0.889 & Spur.

I assume you will do the math for your project and decide what works best for you.

 

Pick your ratios based on your needs, your power output, your car setup, the tracks your race schedule will take you to... etc.

 

Thanks! You assume correctly.

I completely agree. I can't imagine someone plunking down $12k+ for this trans without running extensive calculation and analysis.

 

I'm surprised you guys just didnt use a tilton release bearing instead of the fork and miata hydros.

 

Yay Brexit! These Quaifes are now more affordable than ever!

I look forward to the day you get it rolling E! Remind me again what motor this will be paired with?

 

Don't remind me, I bought it about 2 months too early didn't I? For now it's going into Taxi with a 180 horse 2 liter. The plan was to go into the OGK but frankly I think the ogk might not get built for a few years now. We have sort of switched gears and are focused on building our S1. That said, our S1 will be built to be somewhat competitive in ST2 and ST3 so we can drop the Quaife into it and have some fun once or twice a year with the Vettes.

 

Should be fun in Taxi! With the sequential that 180hp will catch a few by surprise. I've been following the S1 build specs. Should be a fun series! I was really hoping to see Whammy with that sequential in a capable chassis. If you still have the motor when my $$$ loosens up at the end of the year it's gonna be mine! I'll then complete the pairing.

 

The 13.5:1 200whp 2.0L is the one in Taxi but with 11.0:1 pistons. Should make 180 or so on gas. We no longer offer built engines, just our CNC heads. Logistics for complete engines were too time-consuming and the program was just not cost-effective.
