i have a s2 box in mine tunnel needs a little beating though im goin s4 box n bigger tunnel now

no idea on the actual size of the mazda boxes, but when ANGE did his 12a conversion he welded a bigger tunnel in to accomodate the gearbox

im a big fan of new trans tunnels, and the stock ones are tiny and i doubt would have enough clearance to pass engineers with a larger box in them

Go onto ausrotary and search in the tech section, there's a fair bit of info about 12A's and 13b's into 1200 utes. You'll need a bigger tunnel I'm pretty sure but even if it's a tight squeeze and like PIGDOG new tunnels are just so much easier in the long run.

does anyone know if i need to change to trans tunnel to fit the 13b in my 1200 ute? i have gone to alot of trouble to rebuild my ute so it doesnt have any rust at all in it. so im doing the engine swap while its in pieces. just wondering about the size of the trans tunnel because i dont really want to change it, but if it needs to be done, well its gana have to. cheers

thanks mate. i missed out by $1 :(

check this out, there is only 30 mins to go on ebay for this rotary fitting kit.for 30 bucks at the moment.ebay

as soon as i posted that i knew someone would correct me. i have a series 3 rx7 but it has been changed to a 13b.

does anyone know where i can get a template for a 13b crossmember into 1200ute?

They still have 12A's

Your car will still need to be engineered with or without the maddat one. Check with an engineer there requirements for thickness of plate to use i would at least be saying 4mm bent therefore you have minimal joins/welds. My view is $1200 can go a long way when you make your own or even get it mocked up and get it welded ,if ya like me and cant weld yet.
