Greddy vs avo stage 1 Pros and cons of each
 

Any one have experience or know a lot about each one of these want to chime in?

Even if you can't compare them but you have either kit can you elaborate on whether it was worth it. List what you like or didn't

Im looking to increase power and still daily drive so about 250whp.

I already have a greddy evo 3.

These kits are similiar in prices so im thinking of these.

What i do like about the AVO is the UEL so it has the boxer rumble

Lastly, a clutch and upgraded brakes is recommended right?

PLEASE LIST PROS / CONS don't just type GREDDY > AVO, AVO SUCKS , GREDDY SUCKS ETC.

That doesn't help my decision.

Have experience with the Greddy kit and would recommend it for your power goals. I daily drive my car and it has a very oem feel to it, power is linear throughout the whole band and it sounds great. Quality is also very nice on this kit. You shouldn't need a clutch for your power goal. As for brakes most people would recommend it even in NA form but you can still daily drive this with the oem setup for brakes. Let me know if you have any other questions or concerns, i'm local to you if you would like to see the setup in person or have a ride.

I have the avo stage 1.5 and im making 255whp. The kit is great. Its all ceramic coated and low mounted so heat isnt an issue at all. I have 15k miles on my turbo and not a single issue. Power is smooth but you can feel it. Also its really low profile which I guess is a big deal for people in california.

Thanks guys. Keep it coming.

I'm pretty much a noob, so bare with me lol.

Any supporting mods tony?

Did you get an oil cooler, radiator etc?

I have the AVO kit and I love it so far. I chose it over the GReddy for a few reasons:

AVO Pros:
-Placement. The mounting position keeps the centre of gravity low, and also is better for heat management
-It's ceramic coated
-It's been extensively tested on the track and on the road. It's also a product sold by a large global company around the world.
-OEM Subaru oil pump. From the research I did, it looked like AVO was the only one using this oil system. It seems to be the most reliable, however, I don't think I've read about an oil starved turbo shitting the bed on any turbo kit for this platform yet.
-Comes with an ECUTEK base map but can still be used as a tuner kit. It's also held in high regard by some larger FA20 tuners (drift office/delicious)
-Fast spool with lots of torque early on in the rev range
-OEM look when installed, without all of the flashy engine bay bling. Some may consider that a con.
-At the time, the UEL was a pro. Now that I have it up and running, I don't think I would of cared as much if it were EL. The rumble sounds bad ass, but at low rpm it kinda sounds like it's permanently misfiring. Either way, I love the sound.

AVO Cons:
-I had a few issues with the install. Some could argue that there are the odd quality control issue at the factory level, but the customer service made up for it somewhat. Others who have had issues would agree.
-It's quite pricey for the size of turbo and amount of power it can make, but compared to the GReddy at full MSRP, it's a bargain.
-Ceiling is 350hp and boost will drop off @ higher rpm


Whichever kit you chose, you will most definitely need a boost gauge and AFR gauge just to spot any issues before your engine explodes. I also opted for Oil Pressure and Temp, but that isn't as important as the first two. An oil cooler and radiator would be needed at power levels beyond what you want, or if you plan to track it on a regular basis. Like someone else said, for anything around 220 lbs of torque at the wheels, you won't need a clutch but understand that yours won't last as long as an NA car. The brakes would be sufficient as long as you don't track it often, however, a pad and fluid upgrade is a drop in the bucket cost wise compared to a turbo install so just do it at the same time. It will literally take an hour to swap your pads and fluid and cost around $200 give or take. I did SS brake lines at the same time since I was bleeding out the fluid anyways.

You should also take a look at the SBD kit. They are selling a kit VERY similar to the GReddy setup, but they ship with ECUTEK maps at no charge, and also seem to have awesome customer service. From what I saw, they are also offering an ECU controlled boost controller with their kit, which is awesome. Honestly, if the SBD kit were out when I pulled the trigger on the AVO, I may have gone SBD instead.

for the install issues what did you run into? just curious.

A one in a million issue with the turbo water jacket was the major one, but it was replaced at no charge obviously. Aside from that, the only other issues I had were bits of the instructions being a bit on the vague side. If you're having someone else install it, that won't be an issue.

If you do go AVO and are installing yourself, I would strongly suggest reading the owners threads in the FI section.

Greddy Pro:
Its not AVO.

If the AVO was available without the turbo, Id buy the kit tomorrow.

elaborate on what you are saying.

doesn't sound like english lol

He is saying that if he could buy the kit minus the turbo (so as to select his own turbo) he would buy it.


I went with the AVO kit because I got to witness a lot of the R&D that happened here stateside with the kit, so I know the amount of time and thought that went into the system and what it is capable of. I know the guys at AVO are super knowledgable, and I am fortunate enough to have Paul's office a short drive from my house, so I can talk to him about any questions/comments/concerns in person. The layout of the kit mimics what Subaru is doing for the FA20DIT engines. Stock cooling system is more than enough, no need for a new radiator with slim fans, oil cooler, etc. It seems like it is the lowest maintenance turbo kit (relatively speaking) on the market.


Thanks for your compelling argument in this thread. You're just a wealth of information. Keep it up - you're doing the lord's work, son.

Thats exactly correct.
Ive done a lot of research on all kits out there for our track car and the AVO ticks almost all the boxes for me except for the turbo.
If the header was available either as a t/s or a Vband and there was some turbo selction like the GTX series, it would be the best kit out there.

Also Paul seems to answer peoples concerns, so thats a huge positive as well

You could always get the kit and have the flange cut off and replaced with what you want? :iono:

The basic avo turbo has been working great for me. And flows enough for me to make 400/350 on e85
