AVO turbo kit for BRZ - initial build thread

[GC GTS Aero Kit]

Im definitely keen on this for my RHD setup in Australia on my GTS. Do we have an ETA for this as Im keen to be the first to have this kit

You mean there's no Turbo charger futures market?

So seems to me there is a different focus to the AVO vs AP kit.
Yes, the AVO kit is cheaper. But, it has for example an internal wastegated turbo vs a nicer vband external wastegate turbo of the AP kit. Sure the AVO kit comes with a header, but it then locks you to UEL. May not be bad for some, but the AP kit leaves you to choose your own header design, and replaces the overpipe, which the AVO kit leaves you pick up elsewhere. The AVO kit has silicone hoses, which might be ok for some, but the AP kit has more stout solid piping.

So in conclusion, seems to me the currently proposed AVO kit is a more entry level kit, and the AP, while being more expensive, is more expensive for a reason, especially if you are looking to run higher levels of boost down the road.

Would we assume that if we bought this kit we would need to supply and design our own scavenge pump?

We will providing all parts to bolt the kit in and go - which include the oil supply. We won't be asking people to make up their own scavenge pump. The scavenge pump/fittings are included as well. Just can't give away too much information at this time.

Now this is useful information and what we need more of, comparing the different options so as to know what you are paying for. thanks.

But again, this comes to the strength of the internals, which doesn't have any descent statistics yet...


BTW thanks so much for this stealth approach for the design

Currently, 4~5psi.

While we have general ideas of what is going to be doable for power figures, I'm reluctant to give any figures until we've decided on a final turbo sizing, and we've had a lot more testing done.

To give an example, our turbo kit on the Impreza 2.5i adds between 70-100whp, roughly doubling the output, on about 5psi of boost. That's on a 2.5-liter with 10:1 compression. Upping the boost a bit higher would give us larger power figures to boast about, but the truth is that 5-6psi is the maximum you want to run and remain reliable on a stock engine.

Reliable, of course, is a relative term. For some people, if the engine holds together for 20-30k miles, that's reliable enough. The Outback 2.5i here at the shop that we fitted the turbo kit to, two years ago, has 199,000 miles on the odometer. That's what we aim for with our kits.

In regards to the question about head gaskets, it's theoretically possible that would help. But we won't know till it's done. From experience, 90% of the people fitting a turbo kit will never open the engine up. We will have options available for people going much further.

There are going to be pluses and minuses and comparisons between every kit which comes out. I wouldn't draw the conclusion however the AVO kit is "entry level." My guess is on a stock engine car both of them will probably make similar power and both will allow using larger turbos down the line. AVO has been making quality NA turbo kits for Subarus for a long time.

Personally, I think it's a little premature to start making too many comparisons. AP has released tons of info and kept us involved with the entire process. We know a lot about it.

Here, AVO has just started informing us on what's going on. We'll have to wait and see how much they involve us in the process though I hope they are as informative. Yes, they've told us about their intentions for turbo location, exhaust manifold, and intake piping but they haven't released a full parts list or any results yet.

How can you compare what the kits include/exclude without major assumptions? You can't. I'll just sit back, relax and push F5 as I'm still doing in the other thread.

I wasn't drawing conclusions with that post. And yes, on low boost, they may react similarly, thats yet to be seen since we are still early on the AVO kit. Although the AP has an external wastegate which might help it out with low boost.

I don't think its premature.
You can compare what the kits include/exclude by going by what the developers say they include/exclude.
When AVO says "All intake and intercooler piping will be made of wire-reinforced Silicone, and will only be available in Black" there isn't much room for interpretation or assumptions. etc.

Absolutely dissagree with this. While they may be only informing us of their product, it's comments and early comparisons that have led other developers to make subtle changes to their products. I believe this is what they want to hear, what we would be willing to buy and what may turn us away.

For what it's worth.. I like the silicon tubes for much of the IC charge piping. It allows more flexibility, cuts down on cost, and offers the same functionality. The only part I would prefer to have in aluminum would be the visible parts on the top of the engine bay. In this case, however, with the turbo being mounted on the bottom of the engine bay these pipes would be mostly invisible. It would be nice if the top portion of the cold pipe was aluminum from midway up the engine to the TB. It would also be nice if the intake pipe was aluminum as well for the portion that is visible from the top of the engine.

From a piping standpoint, I like the idea of having the turbo in front of the motor.. makes things cleaner and easier. The difference is that you require a new exhaust manifold to make it work. But once you've done that, it sure cleans up the system.. nice short runs from intake to turbo, turbo to IC, and IC to TB. Clean and easy!!

In my old life (Nissan 240's) I would have been perfectly happy with 30k from a motor because you could get a replacement used short block for $500 any day of the week.. plus you could do a full motor swap in a matter of a few hours with a buddy in the garage.

Now.. I'm all about long term reliability. These motors probably be more like $5k each... so i'd rather not have to replace them. I'll take 250whp for 100k miles over 300whp for 10k miles.

It's premature to assume that this kit doesn't include oil pump, lines, etc when the maker hasn't said anything one way or the other about it yet and then comment on price compared to a kit on which this has been confirmed

That's irrelevant to what I said before because I've never said anything about oil pump, lines, etc.

However, since AVO said "We will providing all parts to bolt the kit in and go - which include the oil supply." I feel it is safe to assume this kit does include oil pump, lines, etc wherever needed.

That would be for the turbo, exhaust manifold, turbo outlet (to bolt up to standard exhaust), oil/water cooling system, fmic, intake pipe, and a base map (for tuning).

That price is not bad.
