Should I turbo a Na 13b, or just wait to find a 13t2. I don't plan on using the exhaust manifold or the turbo of the 13bt2. I am going to set it up in a Rx3.
The exhaust manifold wont work and i already have a different turbo. Is there that much of a difference internaly in the engines. Thanks for any info.

 

if you already have a turbo and can make a manifold, just turbo the n/a for now while waiting to locate a TII motor. (yes there is a difference, ports, compression...) the manifold will bolt on the same. just run a low boost setup. make sure you have enough fuel. you could easily do an 8psi system.

 

Could I do this very same thing with a NA 12a running a carb setup? If so, what kind of turbo would be good to use on something like this? The motor I would be using is a stock rx7 from 1980.
