Tuning pricing on Subaru BRZ (86 or FRS)

Supercharging, likely $7000 - $8500. Turbo, figure $10k give or take a few hundred. It is a very expensive process because you can't just drop in a supercharger or a turbo and call it good....not if you're going to do it right anyway. You'll need larger fuel injectors, larger fuel and water pumps, and depending on how much boost you are looking to run (particularly with turbos) you're looking at needing a built transmission with oil cooler, forging the internals to take the extra stress, multiple dyno pulls to get everything tuned the way it needs to be. You'll likely need a bigger intake and MAF for the extra air requirements, and if you want maximum benefits you'll also want to get full exhaust done on the car (longtubes, high flow cats, mufflers). By the time you're done, $15k is not out of the realm of possibility. And remember, if you have a warranty it will be voided, MPG's will go down, and the life of the engine and other components will be reduced due to the increased wear and heat of having forced induction. A lot of people don't think about all of the extra parts and pieces that you need to make this a successful project with maximum gains. I would highly, highly suggest you prep the car with all of the aforementioned modifications FIRST before doing either power adder. There's not much point in increasing the air into the engine if you can't also increase the exhaust coming out. Also, you're going to want a reputable shop to do the work. That's another reason the cost is high. These aren't things you can reliably tune with an SCT or Diablo programmer yourself. PLUS...keep in mind that you may have issues getting through inspection depending on the emissions requirements for your county as well. I build hot rods for a living, so I have had the unfortunate pleasure of running into these issues myself on different builds. It can be frustrating, time consuming, and expensive.

Thanks, AA...you made my job easier!

No problem!

Supercharging a Subaru engine doesn't make for a good power curve, so your driving experience will not be as enjoyable as with a turbo. There is a turbo kit by Crawford Performance that's just under 6k.. called the +100 I think. The stock fuel and water pump are both plenty sufficient, although marginally larger injectors are needed. The dual injection system does not need as much help as the older Subaru's did. The stock engine is good till about 350tq and their kit pushes to about 330. As long as you have a super good tune like the above mentioned and stay on top of your maintenance without driving like a maniac, you can keep her alive. Also the 2015+ WRX DIT rods are way stronger than yours so if you swap those out you're safe to push it further.

Is Crawford's curve pretty linear or an old-style slingshot like Subie's 2.0t iterations?

I own a Edelbrock supercharged BRZ. kit cost was around 5500. Plus 3000 of install and custom dyno tune to an all in cost of 8500.

And...?
