125k on the stock motor? umm.... did you do a compression check on this motor?
Most people have there motors replaced around this area,
So you can get a japspec, or a rebuild of yours from kevin landers of rotary resurection with a port job for about a thousand.
Get a hybrid turbo from bryan at bnrsupercars.com
for safe boost to 19psi+.
then get a full exhaust and intake, not just the cone, but the turbo inlet duct. you can make this from pvc to save some cash.
you'll also wanna invest in extra fuel. new fuel pump, bigger injectors, fuel controller. etc.........
and get some guages to monitor your stuff. You never want a rotary to run lean underboost. This will deff take out your motor.
And after that, you may wanna get a front mount intercooler, as you souldn't run more that 10-11 psi through the stock one. more than this is just rediculous.
And then you can move into getting a new clutch and flywheel. for a little extra takeoff power, just makesure you get some good suspension and tires, or else you'll just roast them.......

you can get around 250 hp with stock turbo, but not RELAIBLE power. the best way is with bigger turbo, haltech, big intercooler, full intake and exhaust, and supporting fuel mods of course. check my sig. what i got is good for i guess around 225 at the wheels. my car is pretty quick. i have no probs takin down light mod F-bodies, mustangs, and C4s

I'd rebuild the engine first.  Turbo FC engines over 100k have very thin apex seals.  You might be safe, but increases of power would be enough to strain the thinning apex seals to crack and collapse.  Ask vosko about his engine...

Lol, I was JUST about to say... Talk to Vosko about modding your aging TII. Are we talking 250 bhp or rwhp? I think 250 bhp is very doable on the stock turbo, and pretty reliable too. Either way, porting the motor would be overkill imho.
