  1. Injectors are extremely easy to source for the 3.0/3.6 - only needed if you want to experience the joys of boost safely. As mentioned - STI injectors slip straight in.

     

    The OEM ignition coils punch out solid sparks, they ignite boosted engines very reliably, the Subaru coil is solid.

     

     

    The path to NA power is in the airfilter/intake system to the throttle body, its in the headers and correct exhaust system and finally its in the tuning of the ECU. You upgrade all those items and you will get the solid gains mentioned by others. Proven and safe path with solid satisfaction :)

  2. Quick update on XRT (Xtreme Racing Tuning) e-tune progress.

     

    We are on the 4th, 5th revision now and the car runs better than ever!

    As smooth and linear as she was in stock form with less than 100 miles on the ODO,

    but of course far far stronger.

     

    Very crisp, quick throttle response all around

    Great low and mid RPM torque and power delivery in any gear

    Strong high RPM and WOT pulls (she pulls hard well above 6K RPM)

    Butter smooth idle

    Drastically better 5EAT behavior (gear selection, holding, engine braking, shifts in auto and manual mode)

    Improved sensor readings and ranges (IAM, A/F Learn and Correct, MAF voltage vs g/sec scaling: happy engine, happy ECU)

    Further refined engine sound (likely as a result of AVCS, base and max knock additive and cruise timing table changes)

     

    The tune has rounded out all the mechanical mods and even stabilized Bank1 and Bank2 AFRs, especially at idle and under CL driving... exactly where I need and want them to match.

     

    Hats off to Ed for his work! We are almost done I bet, just refining at this point.

     

    No matter who does the job, an outcome of happiness is the best outcome of all

  3. The low RPM rattle issue was fixed on mine this past Saturday.

     

    In my case it turned out to be a loose clamp on the mid pipe not too far upstream of the rear axle and diff. It must have vibrated loose over time or was not torqued down well enough the last time the exhaust was off the car.

     

    While here, we inspected the entire exhaust like Tim suggests and found one other 'minor' issue. One of the Bank 2 exhaust port pins was pulled out and never threaded back in by the shop that had the headers off most recently. You can see it in the attached pics, the pin all the way over to the left... compare it to any to the right. We locked it with another nut and fed it back into the block.

     

    Re-checked all points from exhaust ports to the muffler tips out back. Tightened all bolts, nuts, etc. And did a smoke test to check for leaks. None found.

     

    She's as good as new, no rattles, no strange noises 800 to 6.4K RPM

     

    Thankyou for following the advice and getting the desired outcome. It is no different even on my own car - the system must be fault free to be rattle free.

     

    Impressed!

  4. Check clearance around all point of exhaust from front to back and make sure there is no stress or excess pulling at any mount points.

     

    It is an installation issue and I experienced it myself several times when I first developed the product. It not the headers themselves, it's how the entire system is fitted.

     

    Inspection and small adjustments will eliminate the rattle permanently

  5. The spacers are only needed in two cases (Tradewind, please correct me if any of below is incorrect):

     

    a. 5th gen 3.6R with 26mm FSB (either a 2013+ or a 2010-12 with upgraded FSB)

    they help to prevent clearance issues with the headers and FSB once the suspension is loaded once off the lift and/or active when car is in motion

     

    b. 6th gen 3.6R

     

    The information above is correct

     

    Also, a 3.6 mounted in a 4GEN does not need spacers at all, as discovered by spidermanswrx. No 4GEN H6 requires spacers

  6. First impressions: the Mrs. is driving now so I got some time. (btw she's got a big grin too as she punches it)

     

    She was a bit faster at first but the real power came after the 50 miles and ECU got fully dialed in.

     

    Torque: it's definitely a huge increase and suprisingly not overwhelming except right in the beginning when I didn't get the pedal modulation right.

     

    She pulls SO easily at highway, rarely needs to disengage the torque converter to accelerate, even on inclines.

     

    The car just hits 3rd and pulls unlike it ever did before. In fact 4th feels more like 3rd used to.

     

    0-60 is probably low 5s, need to clock but might even be high 4s.

     

    Sound: there is no way to explain it but exotic. Super quiet on highway and its not a growl or a drone, but it's just nice..I think the magnaflow will be added next year. I've heard yours Perscitus and it sounds SO nice.

    That's terrific feedback, the magic is still good!
