AVO turbo kit for BRZ - initial build thread

OEM Turbochargers are, in general, internally wastegated to bleed off boost pressure into the exhaust. It is easier to package that way, and is quieter.

External wastegates became popular because many aftermarket turbochargers simply use an OEM or off the shelf exhaust housing, and the internal wastegate wasn't large enough to keep up with the higher boost of larger compressor wheels that were fit. It would overpower the small wastegates, and boost creep would come into play. The solution was to simply move that to an external wastegate setup.

There is, of course, another solution - make a larger exhaust housing with larger wastegate. However, that solution requires somebody to actually cast and mill the housings themselves. To toot our own horn, and to be also totally blunt about it, we are one of the few that make our own exhaust and compressor housings. Thus we haven't gone down the external wastegate path - if there were boost creep issues, we'd engineer that issue out on the exhaust housings. That's why our AVO380's are running just fine at 30psi on diesel racing trucks on an internal wastegate setup.

But lets be realistic here - a 12:1 compression 2.0-liter engine isn't going to run 30psi, other than on very exotic builds. 5-10psi is likely the limit on a "street" build that's both daily driver friendly and reliable. At those psi/boost levels internal vs. external wastegating is not much of an issue.

I'm happy with whatever keeps the prices down.
I will NEVER pay $5k for a turbo kit plus installation.
I'm aiming to have $5k as a budget with the kit installed.

All said and done, you're probably not going to be under 5k with this one either. (tuning, install, etc.)

I'd throw that budget out the window. Anyone that plans on spending xxx amount of dollars on a kit, and doesn't understand what adding more power does to vehicles. Things are going to break when extra parts are added. Just keep this in mind

This kit looks like it would be a snap to install/take off if going to the dealer for anything. The price is certainly right. All I need is a dyno graph and I'm sold. Then I can finally steal @Visconti for a day and we can have our own turbo fun haha

I wouldn't plan on the following occurring at the same time:

1. Having a turbo
2. Getting warranty work
3. Having a warranty at all
4. Passing emissions in cities


Are you just going to remove the entire turbo kit and reflash a stock tune every time something bad happens? Good luck, I've never seen anyone work that hard or pull it off. Not to mention if they are trying to warranty something big like powertrain related, they'll search the flash-counter. And if you are t-charged, then your counter is likely to be a sky high number from tuning.

There is also no built in flash counter in the ECU - EcuTek has their own flash counter that dealer tools do not see or understand.

When the car comes in for a warranty flash update the dealer tools puts a flash count on the ecu. Only dealer tools can see or change this flash count - much like EcuTeks own flash count.

If there was a flash update available you most likely hear from me first but nothing to worry about. If and when this happens you will backup your new dealer flash with a EcuTek cable so it can be put back in at a later time.

Also with the EcuTek tune the dealer tools or any other flash tools will not be able to override the flash - basically you can not lose your tune when going in for service work.

If you have anymore technical questions about the ecutek tuning tools feel free to take a look at my flash info thread in the ecu technical section as it contains a lot info about this stuff.

In addition, removing the header + turbo + piping looks to be fairly straightforward and rather easy on this motor setup.

My point is, you can only fool the dealership for so long.

Don's done more then 200 dyno runs on 5-8 psi without issue so hopefully it wouldn't have to go to the dealer haha

I get what ya mean though.

yeah but the differences is that this kit is aimed to cost $3,600
so you are ALREADY starting with $1,400 on your pocket vs all other kits that cost $5k.

I've either purchased turbo cars or turbocharged them all my life. Installation wise if you know the right people then it's cheap.
tuning is another story.

you need to understand that when you add FI to a car is because you are willing to lose your warranty PERIOD.

thats why you look for the msot realiable option out there.
running 430whp IS NOT reliable on a tiny engine with such high compression.

this is why I want to stay at 5psi.

Sure it is! E85 baby!

I agree somewhat, I mean if you look at it from other cars. Take a corvette for example the base model has 430hp. Double that with some slick turbo setup and you're looking at 860hp. That's crazy and probably not reliable.

So doubling the output from any car is crazy, if you can do this safely with the FRS, give maybe a 1 year parts warranty, I'd be sold.

We don't know that yet. Look at the f series in the s2000. People run 2x the amount of power on that all day, reliably.

Until someone pops a motor, it's moot. Even then, there are many factors that will play into what made it blow. It's too early to tell.

I wish it wasn't though, lol.

like modding any car, the stock block is only going to last so long.

Trust me I really want to be wrong but I'll believe it when I see it.

I agree, just trying to be optimistic lol.

5psi daily I think will be enough anyways. You have the right idea.
