Mazda N7 Gearbox - Mk3 Mx5

Hi All,
 
I'm looking at removing my Type 9 and replacing it with a stronger transmission to handle the new turbo pinto build.
Searching retroford etc and also local suppliers in Australia, the Mazda N7 5 speed gearbox seems to be getting allot of air time. Viteese etc are also using these.
 
N7 Mazda MX5 Five Speed Gearbox (Used) (MX5-007) – Retroford
 
Does anyone know if there is any difference between Aus delivered N7's and those from over seas? Some local suppliers are saying they are different to Aus supplied models. I just cant imagine Mazda releasing two separate gearboxes for the same car in different markets.
 
Thanks 
Kieran

Taff on FB in Adelaide ( 0882506838) has a few posts saying that also, that Aus  Mazda boxes that he uses are different from those used overseas, but not  exactly how. He advertises that he has them in stock ready to go.
Let me know Kieran if you end up going through with the replacement and you'ré open to selling the type 9.
I need something for my van project once I find a pinto.
 
thanks

Think Robbie think... We just gotsta know

Thanks Robbie... 
Keen to hear from anyone that has fitted one and whether any tunnel massaging is required..... I got the Type 9 in a manual tunnel with no chopping (apart from gearstick hole) so it would be good to do that again....
I also wonder about the gearstick location relative to the Type 9. I could look that up but just keen to hear first hand experience.

We did get 5pd mx5 Miata here in the older version, I think everyone is after the stronger box from the European mx5.
Sell me the 6sp only if it bolts to a duratec

I had a sunlight silver 2.0 NC manual when they were launched, which had the 6 speed.
it was a great little car that worked well as  package.
Only thing it lacked was a back seat, which meant a trade in for an RX8 instead, which drank more oil than juice.
 
How did you get on Kieran?
