Ok this would be my first RX-7 and I must say Im quite excited to have such a unique car with such a unique engine!
With that said I don't know much about getting more power out of this engine. I have done plenty of research but would like to get a possible opinion on here as far as what a good start would be.

Heres what I got:
1990 FC 1.3B S5 5spd.

Now the route I wanna take possibly is turbo... but I noticed there are no aftermarket kits available to boost the current engine... but I did notice that there are very cheap turbo II engines on the market online that have already everything on it...
So with that, I was wondering A:"should I go with getting a complete 1.3b turbo + would it be a direct swap?" B:"will that engine turbo be acceptable to upgrade bc I hopefully wanna get around the 250 - 300hp range?" or C:"is there any other possible direction I could be going down?"

Thanks in advance and I apologize if this was already asked before since im new to the site.

 

Yes, a TII engine is the simplest way to go, and 250 at the wheels is doable with the stock turbo alone. Swap information is in the 2nd gen FAQ and through the link in my sig (https://www.rx7club.com/2nd-gen-archive-72/s4-na-turbo-swap-details-813825/).
