Is it a direct bolt in... If not what do I need to install...pls someone help would be greatly appreciated

 

I cannot say for sure, but you have to change the driveshaft and tranny or some kinda combo of those parts in addition to rear end. I am trying to get a thread for interchangeable parts going in this forum, there is some info there; but you can look into archives for more in depth answer, and if you find, you can post it in the thread i started, or just send link to it. good luck, i can get definite answer if you pm me and give me a day or two.

 

Speaking of just the rear, you need the turbo diff and axles and it will bolt into the N/A rear suspension. However, it will not bolt to a N/A driveshaft.

 

Exactly. I'm 99% sure you can get a driveshaft to fit the TII rear end to the NA transmission from www.Mazdatrix.com

Be careful though... they say the NA transmission can't hold up to as much abuse as the NA rear. Neither can take a lot of power, but the tranny is said to be the weaker link.
