Boosting The BRZ

I haven’t intentionally been avoiding discussion on the BRZ, it’s just not something I’ve paid close attention to. However today, I’ve been catching up on the forums and getting a better idea of the car and just what’s available for it. One thing many people agree on is that the BRZ is underpowered. There are those who will defend it’s simplicity and argue that the N/A 2L FA20 is more than enough for a car the size of a Miata. In keeping with that mentality, a small engine makes perfect sense because the BRZ isn’t about all out power, but rather all of the car’s functions working in perfect harmony. I’m sure most BRZ owners will leave their cars virtually untouched, but what about those looking for a bit more power?

There have been rumors that a turbo version of the BRZ is in the works, but that it won’t be available in the North American market. Luckily manufacturers like AVO have been developing turbo kits as direct bolt on applications for the FA20.

AVO’s turbo kit is still in the prototype stages, but it’s been progressing rather nicely. Designed for high boost response and lots of midrange power, the kit incorporates the OEM intake box for a more stealth look.

The kit will most likely be tuned around 5-6psi, which sounds very conservative. This is a result of the FA20’s higher compression ratio around 12:5:1.

There’s been lots of discussion about the FA20 easily handling more power, one has already been tuned to 8psi. However the issue here is reliability and AVO’s goal seems to be more along the lines of creating a kit that’s easy to live with.

The black silicon piping and black FMIC aid in keeping the car as OEM looking as possible. It also brings up an interesting discussion of how other tuners and individuals seem to be forgoing the flashy engine bay look, for something more reserved. Emissions testing and overbearing law enforcement are no longer factors unique to California. Many other states (and countries) are jumping on board the emissions wagon, so it was important for AVO to recognize those factors in the design of their kit.

Looking at the engine bay, there’s no way an untrained eye would notice anything array. AVO has even said the blue coupling, will not be included in the final kit. BRZ owners certainly have the option of using the AVO kit as a base to mix and match different parts, but it will come from their factory as a complete application. Hopefully more manufacturers will be inspired to follow their lead and give the BRZ market additional choices. Since we can only hope for a factory turbo model in the US, aftermarket kits provide a nice solution in the meantime.

I’ll be continuing this discussion in future posts as more info is published from AVO. Keep in mind this is still a prototype kit and the type of turbo has not been chosen, so nothing is set in stone.

  1. It’s not a STI. More power would be nice, but I’d prefer it in the form of ~250-300 HP N/A with an extra thousand revs.
