Where am i going with this??
Hey guys, back at the crossroads again, and i need some help deciding where to go. My first set of plans was to be able to use my stock lim, and a fd uim, along with the fd throttle body. The motor is a halfbridge 13bt, and i was gonna go s372 on one of turblown's manifold. FJO water injection, and 900;1600 injectors.
I was doing some research, and i saw that some of the fastest and most powerful rotaries use a J&W styled lim, massive throttle body, 8 injectors, and all with the same turbo that i would like to use, or bigger.
What i wanna know is, would this type of setup be overkill for a street driven/drag race car???I am only aiming for about 630+, and i know people have done this with the stockers.... But i would like to make my power the most "efficient" way that i could. Give me some help guys...

I just thought of this to ask you guys also..I know it's probably been covered before, but im gonna ask anyway.
How much hp would the stock uim and lim support???? Whether it be bt, brew, or b-re.
I know alot of rotary drag racers had the option of keeping the stock ****, or upgrading to the "extreme", and i guess they chose the latter for some good reason.
And im 70% sure that most of them using this setup aren't making that much more power than what my goals are.
Let me make it clear also....when i say i want like 630, i mean like 630 on pump gas maybe....and i also want room to try and get as much power as possible before she goes pop.

630hp on pump gas? e85 is from the pump other than that i don't know if anyone has made that much on 93 octane. keep the original setup and use 4 1600 injectors. just my 2 cents

Thats why i said maybe, and im also spraying 50/50, so the "maybe" may be possible.....
Trust me guys, i think i have gone over this a million times in my head to figure out whether an upgrade like this would be necessary...what i have come to, from reading lots of threads on this forums and others, is that i know i could have gotten that type of power with a much smaller turbo, maybe even with a gt37.
But from high school physics, as pressure increases, so does temperature. Why should i have to run 30+psi on a smaller, or more "less efficient" single turbo setup, and be at or close to the limits of the turbo?? I could run a larger turbo, higher flowing intake manifold and throttle body, and much more fuel.....
Think of my theory like Usain Bolt......he knows he can run much faster, but he wont until he is challenged. So if i could make the same amount of power at less boost, and at a lower duty cycle because of much "larger" components, what's there to stop me but detonation????

good.
Now that i see that my idea makes sense, i need to ask one or two questions. What size injectors is usually used???? I know there is a equation to work out how much fuel i would need, but im lazy. Would 1000's be sufficient??

good fuel+ decent size port + a 60mm or bigger turbo should get you around the 600's on medium to low boost.
Those brog warner turbos ive seen everywhere From what ive seen they make globs of power.
but im still going to stay with my garrett turbo!

If i were to run 4 1680's, would this work with the 8 injector t/b???

Me lol. I had 467 and want to hit the 500rwhp mark(since i got beat by a KB 03 SVT only 1 and 1/2 cars from a 30 roll and he has 700rwhp+ so he says). I trapped a 124 with that, but at this level with 265 s03s(worn out) its spin city 1st and 2nd on the street and even spins in 2nd moving when i hit boost. Im on a weird BW turbo like a 61.5mm extened tip, little bit bigger than a 35r.

That who the hell would be me...i plan on drag racing the car also, and i want a bonafide race car. My version of street driving will be about maybe one day a week, and only to events... You guys also gatta understand, where i am, i can count the amount of running rx7's on one hand.......pitiful
My island is ONLY 21x7 (miles).....Yea we have a shitload of skylines, evo's, silvias, 180sx's, and whatever else you could think of from japan....forgot to mention a JUN skyline also.....2 rotary powered drag race cars, a 13b corolla, and a 13b 1st gen; 5.7-6.0, 5.4-6.0 (1/8 mile). So for me to have a really fast street and drag rotary, i need to be at the top of the game, and i cant bullshit.
We have no dyno, no competent machine shops, and hardly any race gas at times....the import shops down here only car dumb **** like spark plugs, badges, and air freshner and ****.. The only way i have of making my car faster is to look around the forums and see what works best, and a whole lot of trial and error....
Maybe only about 4 people down here know about meth injection, and only 1 person runs meth only.
So that being said, I know one day i would probably send the car to a chassis shop and let them 3/4 it, and i would probably be running straight meth around that time. But until then, i wanna "prepare" the car as much as possible and get it close, very close, to that level, so when the day comes the transition to strictly drag race will be somewhat smooth..
Dont mean to rant so much, but picture having a rotary in a town full of people who think that mustangs are the fastest cars on the planet...how would u feel????? I need guys like crispeed, 1revvin7, 13b-rx3, viking war hammer, in fact, why don't some of you guys organize to come down here for a drag race event??? All expenses paid. I need to start the re-education of combustion motors in the bahamas with rotaries.
P.S the fastest car over here is a 91 mustang that's on straight meth, 13.5 slicks, full tube chassis......he run's 4.8 - 5.3's all day.............wtf??

i hear ya mikeb89fc...
you have goals and you're doing what you have to, to acquire them. completely understandable. sounds like you're have some stiff competition and you simply want to be competitive. nothing wrong with that. it's frustrating at times when people apply their own environmental settings into an equation that requires higher goals and standards. keep us updated on your endeavors and best of luck.
