Same ballpark as my car made, it was CTLex's car, I think the engine mods are:

 

perrin tmic

avo tb hose

vf52 turbo

cobb catted down pipe

perrin catback

perrin catch can

dw 740 injectors

dw 65 fuel pump

Killer B Holyheader & up pipe

cobb radiator cover plate

removed banjo bolt filter

act hd clutch w/ 07 wrx flywheel

gfb diverter valve/bov

underdrive crank pulley

AccesPort v3

Grimmspeed electronic boost controller

AEM (I think) 3in intake

killer b oil pickup and windage tray

optima red top

primitive racing skid plate

 

The boost controller, AP, headers, & intake were my additions, everything else came in the car. I had ECS in Windosr tune it for me...

Car made 317 awhp & 348 awtq last March, probably in the mid 30's temperature wise, was running 93 octane, I can't remember what kind of dyno they have over there.

I would esitimate high 13's, low 14's with good driving. I will have a similar setup as well come spring. I will be hitting the 1/4 mile at some point in the summer too. I'm installing a VF52 because dollar for dollar and for sheer simplicity (both tuning and installation, supporting mods needed etc.) its probably the most fun daily drivable turbo you can run. For daily driving it really does give you more for less.

No times on current setup. Went 13.4 with a 1.9 second 60 foot at 103mph on stock intake,stock injectors,stock tmic and my tune on 18psi tapering to 14 psi which I estimated at about 260 to 270whp. I've only had 3 passes in the car at the time. Also,the stock 2.5i rear diff/bushings were clunking so bad on the shift it was picking it up as knock and pulling as much as 6 degrees out lol. Since then I've fixed that, gotten a little better at launching and flat shifting. I'm hoping for a mid..ish 12. Feels like it has a 110ish trap speed in it based on cars I've driven and umm...raced... Couple more weeks and I'll have a real time slip.

Might wanna start saving for a new clutch lol a stock replacement isn't gonna last. (Well mine didn't at least) I went with a southbend and I love it compared to the stock clutch

03 WRB WRX (RIP)

04 JBP STI (sold)

07 DGM Legacy GT (RIP)

12 OBP STI (DD)

With good Drivers yes but with a 52 or a 16G those times will not significantly improve.
where are you getting that from? Your initial estimate of high 13's low 14's is off a bit..it will be faster than my 13.4 with 70 more hp, ffs and lc. I'm going to the track Sunday so I'll post my results.

Yea I have to agree the OP's car will run mid to high 12's with a good driver. My Wagon ran 13.8 many years ago before all the tuning and mods. Just on a MBC.

 

It will run a high 12 now just by the feel and having had a car for many years that was that fast.

 

BTW it ran the 13.8 at LVDW in NY.

 

We also ran the civic in the avatar at 9.85 there.

305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).  CHECK your oil, these cars use it.

I agree apexi is high quality stuff how many tips is it?

 

I love my apexi RS exhaust it is on my supra though but it has big piping while still staying quiet driving around and great when wide open

With that hp you definitely could be in the 12s.

 

My car dynoed at 339hp / 360 ft lbs (corrected) and I ran a 13.2 @ 106.5 at full Limited weight (3500+ lbs). Granted I'm in Denver and things are different at our altitude, but it's a fair comparison. The mphs were plenty for 12s, if only the driver were better.
