13b NA and 13b Turbo engine differences.

Can someone tell me the main difference in these engines? Besides the turbo engine having lower compression?

Thanks

how can I lower the compression on my NA and make it boost ready? Will the 13b turbo rotors fit and bolt up?

search for a thread "project tina" aaron cake also has a write up on his webpage regarding turboing N/A cars....

to lower the compression ratio in your N/A motor you would need to install the entire rotating assembly from a turbo motor (turbo rotors, e-shaft, counterweights etc.) but it would be easier to do a TII swap....which again has been covered countless times....

You can't.

Only if you take the engine engine apart and put it back together again.

Copied directly from the FAQ:

Can I swap a Turbo engine/Jspec engine/13BT/etc into my Non Turbo?
Yes, check these links:
https://www.rx7club.com/forum/showth...threadid=26647
http://www.rotaryresurrection.com/ro...conversion.htm

How do I add a turbo to my NA 13B?
What Turbo kits can I add onto my non turbo RX-7?
There are no longer kits formally made at the time of this post, however there are companies from time to time that do make available non turbo to Turbo Kits. Because most of these companies stop building the kits, or go out of business in short time, it is impossible to keep active links for them.

Most people that turbo a non turbo make their own kits:
Using the stock TII turbo, exhaust manifold with spacer, NA intakes and NA ECU:
