She can push a hell of a lot more power but its a daily drive and I rather have my engine last for awhile. Thanks for looking

Did you make a mistake on your target AFR? Cause at WOT throttle its def not at 15.3

ID doesn't make 1100 injector and even if they did why would you replace 1000cc injectors with them??

You won't run out of fuel on pump gas w/FIC 1000's, stock fuel rails will be fine, and the FPR is not neccessary (43.5 psi rail pressure with those injectors will be fine). Anything other than a stock map sensor will have no functional use unless you plan to run speed density.

Not trying to sharp shoot your plans, I'm just saying you have no reason to not turn up the boost and actually use the turbo you're running. You may as well run a smaller turbo because you can get that power with better response on something much smaller.

In the words of Nick Diaz, "don't be scared homie!"

Thanks for the constructive comment man. I will probbably swing by PIA soon to get her retune to about 23psi. What do you suggest I can push up with my current build? Thanks

Truth is your tuner is the best person to get this advice from. There might be something we're not seeing here, who knows. I find it hard to believe a good shop would just leave you hanging in the power department unnecessarily while you save your money to really max your setup. From the information you've given, I can't see any reason not to push it at least to a conservative knock threshold, which should probably be around mid 20's boost on pump gas. That's just a guess though. I don't have any experience with that turbo/fuel combo and I'm not a tuner by any means.

Keep at it and good luck, you're going to love it when you get it running strong. Any chance of running E85 in your area? Maybe consider meth if not, that turbo really comes alive beyond the 25 mark.

EDIT: you mentioned having your engine last a while...with forged pistons, your engine is not your limit.

Not planning on running E85 nor meth but will diffidently get her tune up to as much psi as possible on pump 92. Wish it was higher octane but rainy Washington state only offers 92. Thanks again.

how do you like that clutch compared to stock for daily drivability

Its not too bad. It takes a little while to get used to but you'll eventually learn to love it. The only downside is that it does become quite a pain in rush hour because the Clutch really wont engage until RPM is beyond 1k. I drove my buddy 04 STi the other day and his is all stock and to me it felt harder. Once you learn how to feather it and know the sweet spot then its just like any other manual. But overall is feasible for daily driving but not recommend for heavy traffic DD.

There is a lot of information that is not being delivered here or is being delivered incorrectly. His car was put on the dyno for basically a break in tune. The "break in" tune was done via Cobb Accesstuner Race by someone who didn't / doesn't know subaru's.

-Ignition timing was set to 14* from a load of 2-2.75 from 3200 RPMS to Redline
-The engine load was not rescaled.
-To scale the maf sensor, they changed injector scaling until the car ran decently.
-Primary fueling Table was left stock.

Based on all of this information and more, I could not let him leave the shop with his state of tune in this condition. I made some recommendations based on my own personal experience so that he would be able to max the setup out in the future.

-FIC1100 Top Feed Conversion to get away from the modified stock sidefeed injectors.
-Aftermarket regulator to suit the new rails (Not 100% necessary, but I have yet to have an aftermarket regulator fail and I have had more than a dozen factory regulators fail)
-The addition of an Intake Air temp sensor
-The addition of an AEM 3.5 Bar map sensor.

The car was tuned via Speed Density utilizing the MAF intake air temp sensor that is in the intercooler piping due to a blow through configuration. The boost was not pushed past 19 PSI due to 90% IDC and the Stock Map sensor. There is for sure more left in the setup. On good pump gas with 22-24 psi, It's very common for this setup to do about 430 wheel on PIA's mustang dyno.

AFR Target under load was 11.5.

The modifications on the car when I Tuned it back in october were:
Built Block (pistons and rods)
Stock heads and cams
TXS Rotated Kit with 35R 0.82 A/R
Tial 44mm EWG
FMIC with Blow Through MAF
Modified Stock injectors (sidefeeds)
Stock Fuel Rails and regulator
Perrin BCS



I'm happy to answer any other questions anyone has.

Imho this clutch won't last you long, it could just be me. But I have the same clutch on a 6mt swapped 375whp 360wtq 2.0. And after 3k miles its slipping bad in 3rd up. Was broke in for 750 city miles.

Wow is that you Mike? Thanks for helping man. Still saving up the money but should be able to swing by around tax return time. Thanks again for everything.

Ahh, there we go. Felt like something was missing. Looking forward to what this thing does when it's all set up!

I am on 8k miles mark with this clutch and it still feels solid. Haven't notice a lot of slipping and I've put it through some abusive driving for 2k of those miles. Dont know, could be just a fluke but I hope not.
