having regularly auto-crossed my 270 whp turbo RX-7 and my 160 hp 20V 4age swapped corolla (no torque, nothing happens until about 5k) I don't think you're going to like a built NA very much for auto-x.
most of the time in auto-x you're not at the right RPM so you won't be able to use most of that 300 whp even if you do get it at 10000 rpm or whatever you'll be revving to. you'll be stuck down at 3000 rpm making like 50 hp.
if you're really serious about this I would get a really high final drive ratio (4.7 or more) and really small tires (the smallest you can fit around your brakes, you're probably going to want to run 275/35/15 Hoosier A6s.)
I run 255/40/13s on my corolla and it's still not very fun in slow corners.

I'm guessing this never happened 
. Hey OP, I can build a n/a motor that'll do 400hp n/a, I promise. I'll do it in a couple months. Since I say it can do 400, it means you're already successful at doing so. So, yaaayyyy! You're the proud owner of a 400hp n/a rotary!! It doesn't exist yet, but still...

I gotta say, I've been thinking about your 300rwhp claim all day, and I've come to theses conclusions:
The cash you'll end up spending on getting an NA up to 300 is a waste of money and your powerband will actually be less than a turbo powerband. Sure you'll hit 300 with that NA, but at what rpms? 8K? 9K? 10+K rpms? So you'll have a useless powerband and then power for about 2k rpms and not suitable for autoX
Have you ever even driven a turbo rotary or any turbo engine for that matter? Boost is not an ON and OFF sort of thing. My rx I autoX with is wasted to 13psi, does it ever get up to 13psi? hardly never in an autoX. How about in a turn and then suddenly boosting and loosing control? Are you joking? You'd have to litterally punch the throttle and hold before the turn and while in the turn in order for the turbo to spool up high enough to make a spin out. Doesn't happen. Boost is variable with throttle input, this is common knowledge. You're not gunna hit full boost at half throttle or really any throttle other than WOT so you can set your spin out from boosting fears aside. My engine hits well over 300rwhp, I have the slips to prove it and if you were to look at my powerband I think even you'd agree its more desirable in an AutoX than a PP NA making almost and much as my turbo engine.
And then again, cost. (lets say this loosely) you could have a rebuilt ported or stock port 13BT, with all the fuel injection goodies, a good cheaper engine management like say an Rtek which mine has, and a decent turbo and its goodies like a FMIC and what not, a nice clutch, and I bet I could put that engine setup together and have it pumping out 300rwhp for around 4 grand.... Care to ball-park the cost of a 300rwhp NA engine?.....
With that said... I'd love to see a 300rwhp NA engine! Bring on the build thread with pictures and videos and what not. Don't get me wrong, I totally support your build, because its not coming out of my wallet

talking head
(222wkw is 333whp btw)
333 rwhp = 248 rwkw
222rwkw is 298 rwhp,, not quite 300 rwhp,, but ill give that one a cigar
as for the OP,, anybody yet mentioned how 4.875 and 5.1 rear ends are not avail for FC's without major bodge of the pinion extension ?

Banned. I got OWNED!!!
ok so for all the people out there that told me i couldnt get over 300 to the wheels while staying naturally aspirated your retarded. Because i'm doing it right now. Fuji Racing is building me a motor with some ITB's on it and i should be accomplishihng this within the next few months. CANT WAIT!!!
But one question. Who has had good experience with different injectors? what has been the best??

The reason i dont want to go turbo is because evryone does and I'd like to be a little different. And I autocross so I'm not down with a turbo spooling up in a corner and losing control. So before talking like a bad *** over the Internet remember you don't know my intentions. And learn how to talk to people respecftully you ******* dumbass.
First - have you done the math and figured out gear ratios and rpm's when changing gears? Do you understand swapping final drives?
Second - Have you ever driven a turbo-charged rotary? Do you understand turbo sizing?
Third - you do realize that torque will get you around a race track not HP? My twin turbo'ed rotary makes more torque at 2500 rpms and carries all the way to redline than your PP will make ANYWHERE.
And lastly; Oh you are different. In fact, I bet the state would classify you as "special"
There are several thousand non-turbo RX-7s throughout the world. Nearly 100% of the winning GT RX-7s from the 80-90's were non-turbo. There have been 300hp NA rotary engines available for well over 20 years, which is about as long as many people on this forum have been alive. Sorry, but I don't see anything new or different here.
I don't suppose that the race shop that is taking your money explained to you that your 300hp PP engine is going to drive like crap on a tight autocross course unless you keep the engine revved up like you would with a turbocharged engine? Also, did you even tell them that it was for autocross, which usually has more noise restrictions when it is held in a parking lot as opposed to a race track, and favors a high-torque intake as opposed to a high-hp intake?
I don't suppose you realize that you sound like a "******* dumbass" by bragging about your engine before it is even built?
Why would you ask a bunch of "******* dumbasses" which injectors to use when you have a professional race shop building your engine?
