Quaife Sequential for NA & NB
Quaife came out with this last year. https://shop.quaife.co.uk/gearboxes?...e=13&vehicle=4 They offer 4 different options for the NA/NB. The 375bhp limit it's somewhat restrictive though. The weight looks to be the same as a stock 6 speed.
The price is pretty tough to swallow. After seeing my friends BMW converted to sequential I had to peak at our options. One can only dream. :-) |
I'd like to get one for the OGK. We will see how the budget looks in 6 months

Interesting that they measure capacity in horsepower. Torque is what kills things.

I was thinking the same thing. The HP may still create heat though. Maybe that's why they rate it that way.
Yes, it's possible to instantly shatter a gear by applying eleventeen-hundred ft/lbs of torque to it with sticky tires and an adequate rear suspension. But the track crowd, who seem to be the ones killing 6-speeds most frequently, have demonstrated that it's not hard to do so with levels of torque and HP comparable to what many of us run reliably on the street through 5-speeds. The difference would appear to be that they are producing said HP on a nearly continual basis for tens of minutes or even hours, rather than in short bursts of a few seconds at a time. It's this continual HP production which leads to the generation of heat in the gearbox. Heat softens things, reduces the effectiveness of the lubricant, changes mechanical tolerances, etc. |
It's rough rating anyway. When it breaks you have applied too much.
But just assuming the rating is focused around a 8-8.5krpm engine, not a 5.5krpm 7L engine. |
Wonder how much longer a 6 speed would last with a transmission cooler.

How about a slightly different question: Would a 6 speed last ANY LONGER with a transmission cooler? I would say yes. There are high powered cars that are stock with a warranty that have transmission cooler. I made a transmission cooler thread a while back, it's somewhere on here. |

I dont know about the qbe60g but the 69g comes with an internal spray bar.
Makes a huge difference. For my K24 build, I chose to go with the S2K trans for a variety of reasons, one of which is down the road Id like to either replace the gearst or go with a stand alone dog box. D |
The69G is rated to 750HP.Should be plenty but eye watering in price.
Sequential gearbox packages for Honda S2000, Mazda MX-5 (NA/NB,) Nissan Silvia SR20DET and Toyota 1JZ / 2JZ Supra. - Quaife |
No flat shifting but here is the 60G in action.

nom nom that noise!!!
|
Holy shit, yes.

That would be epic!
Epic is a good word for it. |
Do it for the grins? And to set records?

In light of Emilio taking the plunge I am bumping this thread back to life.
I am also going to drink the cool aid in late March. Honestly it's not that expensive after selling off both of my 6 speed transmissions. Money is finally starting to loosen up so this should be a good year for racing. I am lost on how to handle the flat shift and auto blipping with the MS3. I am hoping the ECU supports that. Thoughts on the matter would be appreciated. |
