Can we ask why you are looking at a PAR gear set?

For an NA6 ... :shock: Have you checked the price? And the performance?

If you need a stronger gearset, there are other options.

get in contac5 with Mal Woods in Warwick he can make you a Tremec T5 to fit a MX5, uses OEM clutch/flywheel. More than likely cheaper than a gear set. T5 Has lots of ratio and gear choices...

Any good for what? A stock NA6? Boosted? Engine swap?

Why not a 6-speed? It will last longer than a 5-speed …

Of course, you have searched here, and on MT.net … ? There are options if you care to look.

Compared to the BMW option, the par gear set has got to be a contender don’t you think?

I don’t understand this option. The T5 box is rated to 300ft/lb which is about where the Mx5 6speed starts to have issues? Sounds like a lot of fab work, for an option that may not be much better. Maybe I am missing something.

Lot of different t5 gearboxes out there and tremec tko boxes lot stronger than mx5 nb 6 speed box
Mustang v8 below has a built t5 trans

Ive heard tho some t5 style gearboxes dont like shifting over 6700 rpm dont know how true that is tho
Or with upgrades to t5 / tremec box can fix that so called problem

Let's spend more than the value of the car on an overkill gearbox.

This has been discussed on Miataturbo plenty but look at the amount of bracing ribs on the 6 speed compared to the 5.

The PAR gear set is stronger but it’s only half a solution there is still the problem of flex in the gearbox itself which is part of the problem of why the 5 speeds go pop.

That’s why you don’t see much on the PAR not many people run them as it’s more expensive than a 6 speed for half a fix.

The upper limit of a 5 speed is generally agreed to be about 250rwhp but this has a lot to do with the torque curve on the tune and the loose nut behind the steering wheel.
That’s a pretty big amount of power in our cars and also where conrods tend to start turning into steel banana’s.
The easy solution is by a 6 speed (roughly $1000) or buy 3-4 5 speeds for the same money.
Being NA6 the rear diff will be more of a concern unless already running 1.8 gear.

All the best with whatever you go with :D

I’m keen on keeping it a 5 speed
I’ll be using it mostly for drag racing
Seems that there is a lot of mixed comments about the whole thing
I just wanted to know if people here that have used it
Thanks

If it's for drag racing, what about an AUTO?
I don't know how a hi stall torque converter would compare with launch control, either would help avoid fluffing the clutch release operation.

Have considered auto
Manual is too much fun on the street
Have spoken to some workshops and waiting on some quotes
