hey guys im new to the forum ive got a datsun 1200 ute im wanting to put a 13b rotary in it . . .
if anyone knows of companys that sell crossmember and tailshaft kits for this kind of conversion or anywhere i can buy a rx7 front cut please post it up . . . any help would be greatly appreciated

The rotary conversion is not so common because the 13b is considered 2.6L and turbo is considered 3.9L capacity and both are impossibly difficult to register.

Otherwise Maddat are considering making the kits:

How does that rule go with a 120Y? Can you get away with a 13B in a 120Y in turbo form?

For a 4 cylinder and under 1000kgs car,

For 13B NA: you need the weight listed by the registration people as being 867kgs or greater. (2600 divided by 3)

For 13B Turbo: you need the weight listed by the registration people as being 1040kgs or greater. (2600 divided by 2.5)

Basically ..no.
I think the 120Y lists as 820kgs.

now would 12A turbo be ok for 1200 and 120y's???

Even a 10a turbo (if it existed) is not registerable in a regular 1200 or 120Y.

See RTA's vsi06: http://www.shoeys.com/docs/vsi06.pdf

If it were legal, the CA18 option wouldn't be so popular.

Some Ute guys get away with larger engines under 'commercial vehicle' laws in some states.

There is always some guy who has mates of mates who will do a shady deal to get these things registered. But the fine print will generally show that they are not 100% legit, and many cops (And insurance guys) will notice this.

ranga1200 what state will this ute be registered??
in qld a 13b even non turbo is a no no, the only rotary you can put in your ute here is a 12a non turbo , so most guys up here go the ca18det conversion , cause you can get alot more power out of the ca compared to a non turbo 12a even if you go a injected bridgeport a worked ca will have more power and better driveability than the rotor.
but having said that if your after a cruiser to turn heads the rotor would be a good option the old brap of a rotor will get plenty of attention.

O.K the first question should be What State are you in ? and i don't mean mentally HA HA. NSW, QLD, VIC, W.A, S.A, TAS. That makes a difference though not a lot between VIC, QLD, NSW Still a difference and a big one in TAS One fella on here is doing a L series conversion to 1200 sedan in TAS and he has to play by some pretty strict guidelines/Rules.

i was thinking of putting a 13bt in my datto ute. so i might have to do a shifty haha

yeah its all good till you get a defect lol,
i know the cops around my area love defecting cars and impounding them for things like that.
