You don't have to run a turbo to get into the 12's. You also don't have to be ported. Power to weight ratio!!!

riiiight....
rotaries take to forced induction better than non forced, good luck pulling a 12 in an n/a. maybe if you put a 3 rotor into a go kart.

Get a KP61 starlet, 1550lbs, rwd. Throw a 200hp *ported/carb'd" 13b in there and you'll have a 12second car. A non-turbo, non-ported 13b FC running a 12sec 1/4 seems rather fanciful.

Strap a rotary engine to a skateboard and you will go faster than 12's.
It is about power to weight, like it or not.
The question is pretty vague, you have to tell us your goals, your budget, and how mch comfort you are willing to sacrifice.

An n/a FC into the 12's with no porting....sorry, is not gonna happen.
4.33 diff, port/pinned block, 60-1 turbo, big f/m IC, 1600cc inj, Rotary Pro Pack or similar, 3'' exhaust, good EMS, good boost controller, Walbro + inline pump, 9lb flywheel should be enough to run low 12's on pump gas at about 15-18lbs of boost, daily driver too.
On my previous T II I had that combo but with a TO4E and 1200cc inj. + 1 850cc, my best was 12.68 at 18psi.

Interesting answer, but not accurate.. I went faster with less mods..

if you feel it takes weight reduction then add that to your "list".
i wanna know what people "think" it takes to run a low 12 with a s4tii.

first off ASSUMING ur a good driver, (cuz that makes a BIG difference in 1/4)
strip the interior.... everything unnec. goes.. (even carpets and passenger seat)
lose the A/C and P/S window wipers/motors, u name it..
upgrade the Turbine..
open exhaust (just a nice 3.5" downpipe, no exhaust)
Haltech+fuel mods (lose the TID/MAF) (optionally remove the passenger headlight assembly leave and duct cold air from there..
super lightweight flywheel, heavy *** clutch, short shifter..
FMIC with short route smooth piping.. and freeze that **** with some No2 before lining up..
get 2 skinnies in the front... and some fat M/T's in the back
Turn the **** on the B/C...
rev the car till it bounces off the redline
let ur left foot off the clutch
keep ur right foot pinned to the floor board...and power shift like a madman
that should break u into the 12's...
(and hopefully not break ur car doin it)
