Do it!!
you can get 300+hp easy with just a few simple boltons with a 13b turbo.
The easiest and most reliable way to do it of course would be with a complete stand alone fuel management system.
And write a how-to when your at it!

It's been done before....
A while back maybe 4 years ago there was an S13 Silvia with a 13B in it....aptly named the S13B Silvia....
Didn't look like it was too hard to do.
Me and a buddy thought of doing it then decided on using a Mazda roadster (Miata for the US peeps) to drop the 13B in.
Had an FC as a donor car...but the motor was toast and I din't feel like spending money on the rebuild or the time on a DIY Learn as you go project.....

It could definitely work (anything will if you're willing to allocate the resources...) What do the dyno graphs look like for a 300+hp 13b?
I thought the 2 rotors weren't really much for a wide flat torque curve - which may make you regret the swap on a tight road course and definitely on an autocross course.

do the frikin swap.
If i wasnt married....... i'd have a 13b in my 180 now or a rb26 (long story on that one).
this is whats so frigin killer about 13b's...
here is how you FULL TUNE a 13b:
apex seals
a port job
thats it! that is all it takes to full tune a frikin rotary.
of course once you put it in your gonna be blowing diffs and missions etc...
But i think a good posi diff off a mustang will do the trick

He's going to give me a great price on it, so we start going over the idea of a 13b REW powered 240sx. The motor will be going into a '90 Fastback, and it's going to be used for Auto-X. Anyone else have an opinion on this?
Good:
Lighter motor.
More power potential.
Bad:
"I'll make the motor mounts if you make the drive shaft"
If I bought a pack of hot dogs, I'd have to file for bankruptcy.
"What the **** are we doing?"
"You don't really need Apex seals do you?"

I'd run a Tec III system if you go ahead with the swap, it damn near tunes it's self... also junk the stock turbos and put on a To4S A/R 70 compressor and .89 exaust housing P-trim wheel and use the FD mission with a FC tailshaft housing, then you'll be able to fab a tranny mount as the FD uses a power plant frame.. That should get you 400 hp on the stock engine and port with the stock injectors and it should last a long time if tunned properly.. Catch me online if you have any more questions

hey dragon how many engines have u gone through so far? so there must obviously be a fault somewhere in your tuning wouldnt u think?
you most certainly do know alot about all the mechanicals in a rotary but your just a bit off. did i just hear you say that you could run a single with a port job on stock injectors
its well known that at 400 bhp with the stock twins the stock injectors will be pushing a 105-110% duty cycle. and since u obviously know what your talking about you know that that will last for about 1 sec before bye bye. anything above 90 is extremely dangerous because the injectors are no longer working like theyre supposed to. how do u explain this dragon?

I push my engines to the limit testing diffrent port etc, because I have about 3-4 engines worth of part sitting on hand at all times and because I can pull my engine, put a new one together and put it in the car in two days unlike people like yourself...
I've blown 4 engines in 4 years, the last 1 sucked air with a low tank of gas on the launch starving the system of fuel at 10k rpm.. The one before that mearly burnt the very tip off an apex seal boosting 20psi and had no damage other than that. It cost me about $130 to rebuild that engine. The one before that overheated when one of the inner O-rings decided to leak. The 1 before that was when I was running a racing beat ecu with a S-AFC, not good for tunning when you don't know what the map looks like on the computer and you have no tunning resolution to go by and have no control over the ingnition map.. I currently run a Power FC and datalogit with my laptop and I can do anything..
Now back to your question.. you put in an adjustable fuel pressure regulator and run your fuel pressure at 48psi drop in a 255lph walboro fuel pump and boost around 15psi with a To4S and a A/R .89 exaust and you will be right at 85-90% on the injectors. under boost your fuel pressure at 15psi should be around 63psi and the walboro fuel pump still has plenty of flow at that pressure just make sure you get the high output 255lph one and not the low end model 255lph... If he actually goes with a aftermarket EMS like the Tec III then I would recomend getting larger injectors, but he sounds like he's on a budget to me...
If youd like to test me further then ask away...
