Yes, everything has to be rebuilt to fit it all.

Yes, but damnit, a 60 second search would have told you YES, YES, YES!

And I'm not a search nazi normally. But man that was a total n00b move.

Hella flush and all associates should be gunned down for brainwashing people into thinking a 225 and lots of camber is proper wheel fitment. THAT IS EASY, anyone can camber a skinny as tire till it dosnt rub. Now fitting an 11 with a 315 on stock fender with reasonable camber, that is fitment. And looks, and performs better than both.
i dont own a s12 at the moment but trying to acquire one to get rid of my s13 hatch

As Dan/RB25 or I.  We can tell you just about everything you will need to do.  It's great fun after all the work is finished, but getting there is a pita... sometimes depending on the situation, not even worth it.

You need to be mentally sick in the head to beging a swap like this, is what he is trying to say.

only the hard core at heart may only attempt this at all...

on personal note the 4 cyclinder sub frame is easier then v6 version.

This is in relation to modifying the front subframe to make the motor mounts seat correctly due to the angle and stuff.

Never compared the V6 vs I4 subframes.. I used a 240sx subframe which upon reflection doesnt really matter.

Why? Because the RB motor mounts sit SO far forward (almost 8 inches) I didnt want to risk creating a huge moment arm of a mount. I actually built the mounts off the frame rail in true 'v8 muscle' style. The frame needed to be beefed up and lots of welding was done but I prefer this approach to creating a big 'ol offset piece of steel - not to say these types of mounts havent been used with great success, because they indeed have.
