I would absolutely boost again. I went with an easy setup (Sprintex 210), on E85 flexfuel, with a moto-east tune. I did the install myself, and haven't had a single issue in 30k miles.
I'm likely only making 275-285whp depending on temperature, but that is plenty, especially when you consider that I don't track the car or have amazing roads in rural Indiana. I get to have a bit of fun here and there, and plenty of scream/whine from the SC! My entire cost of boost for me sits at $2950 (used SC, oil, tune, flexfuel). Amazing value, none of the mess that folks with big power complain over! ... I was a bit scared to post, as now I'll probably throw a rod tomorrow morning. But let's hope everything stays healthy! |

This feedback is always good. User feedback. Biggest thing I've learned though all of my automobile triumphs and quests is a simple statement.
Happiness is simply your reality vs your expectations. What are we really expecting? This current group of FT86/BRZ owners is still a large group of individuals who paid $20k+ for the vehicle on average and it stings a bit when weighing in on the performance aspect vs other platforms. I'm extremely excited as the prices plummet because this next wave is going to be the "hoonigans" to stuff the FA24 etc etc in this thing. The "I picked up my brz for $5-$8k crowd." Then there's going to be a huge wave. It's hard to toss a 60k powertrain warranty out of the window for a few ponies. I think we have to keep the engineering of the vehicles in mind and what it was designed for, its extremely balanced. I watch the S-Chassis so closely because I think this platform is headed down the same path. There will be a FA STi and there will be a more performance oriented 86/BRZ.

I've been boosted since June of this year on a Harrop 1320 TVS SC with the 85mm pulley (12.5-13 psi) on 91 octane with a DT tune. I'm on E85 with Delicious Tuning's Flex Fuel setup now with the same pulley, and I am loving the car. The difference E85 makes on boost is almost as much as the difference between NA and being boosted; it is that good.
I'm pretty aggressive with my driving too; I don't baby the car at all, yet I am not dropping gears from 5th to 2nd, going to 6k rpms while gunning it, or doing hard launches at every light either. Hopefully the engine holds, but I am not worried at this time. My only safety nets in place are the following (besides the necessaries, DW700cc injectors and DW300c pump): AMSOIL 5w30 Signature Series oil with their oil filter, Forester XT oil regulator/cooler, dual catch cans, and lastly, gauges to monitor pressure and temperature.

But to be fair, my tS is DEFINITELTY quicker than my Crosstrek Stage 0. While this thread has put the fear of god into me with my upcoming JRSC C30 install, I’m acquiring all the supporting mods to try and run it as safe as possible and then cross my fingers and hope for the best! Sorry some of you all have had some terrible experiences, but thanks for sharing so the community continues to learn and grow! |

If you stay with the JR or Delicious tune with standard pulley and add an oil cooler, your car will be faster than the STI (91 octane) and as reliable as stock. None of the problems reported here are factory configuration.

I will be running the standard pulley, JR Oil Cooler, JR 4 Bar MAP Sensor, Forge BPV, (potentially) a catch can, w/ a tune from Moto-East.

I have double catch cans. The crank case side does not collect much, if any, oil. There is mild oil accumulation in the PCV side. JR recommends using the softest spring with BPV. Stiffer springs can provide more immediate boost but they may also cause surge on the compressor buy not opening completely. You can check the MAF reading at idle to make sure BPV is opening. The reading should be below 3 g/s after warm up if the BPV is opening. You can hear the whistle of open BPV. Good luck!

Given that you are still “street racing” in traffic and endangering other motorists your opinions are pretty much null and void. There are endless driving events across the nation where you could accurately test your vehicle and your driving skills, as well as benchmark your vehicle against others. Stop being selfish and take it to track. |

It has been debated here, but I would go with a thicker oil too. All turbocharged Subarus use 5w30. If you are heavily tracking the car then 10w40 or thicker may be safer if pressures aren't staying up.

Everyone is also missing a huge element to motor longevity is not having such sticky tires. Your engine loads will be a lot lower if your wheels are able to slip. High torque at low rpms along with sticky tires is what bends rods.
