Turbo options
Hey, I'm looking into purchasing my first Rx-7. I like the FC, but I was wondering about the turbos. What are particularly good setups for turbos to develop decent hp? Any suggestions as to developing near 250 hp? I heard somewhere that you cant even mount universal turbos on the 13 B engines... please help me out and give me a bit of an education.

The stock turbo is capable of about 275 if you push it hard, but 250 is absoltely possible.
Hybrids usually max out around 315, and are generally the worst of both worlds IMO...slow spool of a larger turbo, with not much more power output than the small stocker.
FOr 300+, I'd recommend a full t4 upgrade with external wastegate. You need a manifold, wastegate, turbo, oil (and coolant, if applicable to your new turbo) plumbing lines, custom downpipe, and custom intake/air filter. Of course you'll need a front mount as well, as the stock IC maxes out with the stock turbo. Along with the full turbo upgrade you generally sacrifice emissions, you require a fuel system, computer/control system, and custom tuning.
And no one would recommend doing all this on an original engine, unless its been recently rebuilt. Turbo rotaries do well to last 15 years on a small stock turbo making 170 at the wheels, please dont try to make 300 at the wheels with a full upgrade on an original engine, or you'll be pulling it all right back out.
To take a stock or near stock car and properly do such a setup usually runs in excess of 5 grand, sometimes twice that.
