im currently removing my 13b in my rx7 na 1987 sport, and putting in a new rotary engine from rx7 world. and i just wanted to know when i get this engine out and put the new one in it should be just plug and play right its the same engine only with upgrade internals.

 

If you're putting in a Renesis, you're gonna be spending more money than you thought.
If you're putting in a 13b-rew, you're gonna be spending more money than you though.
If you're putting in a 13b, you'll be fine.
If you're putting in a 13bt, you're going to be spending more money than you though.

 

Oh **** thanks dude thats good to know, i was thinking about the turbo but i just decided to stick with the 13b.
