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

While I don't own either a big question that's been plaguing my "build" for a while is if I trust an oil pump for the oil return on the turbo. I may have said no in the past for various reasons however I believe AVO has really done it right by driving it off the cam rather than having an electric pump, which I REALLY don't trust.

Is it cause the turbo is limiting? What is it about the turbo that people would rather change it out?

some people like to go big to have the capability to go above 400whp. Few do though.

I have an AVO kit on my BRZ, and love it. It puts out 260whp on 8 psi. If I were living in SoCal there would be no question I would choose the AVO over the Greddy. Your main concern should be HEAT! You will need either an oil cooler, more fans, a vented hood and fenders, or a larger aftermarket radiator to keep a front mount turbo cool in SoCal. With the AVO, you can DD or track the car with no heat issues with the stock cooling system. I do.

Everyone seems to forgot AVO is coming out with a stage 3 option, which will include stage 2, plus 3" piping and a billet compressor wheel.

AVO Pros:

Cheap

AVO Cons:

Poor QC leading to leaking flanges
Poor QC leading to flaking of ceramic coating
Cheap turbo that is too small to hold boost to redline
Sell the kit without a BOV or BPV and expect customer to plug holes
Due to low mount requires complicated oil delivery and return system
Intercooler mounting is not compatibile with most aftermarket oil/water cooling solutions

GReddy Pros:

Short intercooler piping

GReddy Cons:

Expensive
No BOV

I haven't had any qc issues and it's been 10k plus miles at 11-17psi. No fancy gaskets, just new oem

The oil system is much faster to install than having to weld up an oil pan. Again, zero issues and I prefer it over an electric scavenge pump. I'm not against welding up an oil pan though so it wasn't really a concern for me

I do agree, the kit should include the bov from the start

I can't say anything about oil coolers since I don't run one

Boost does taper off, but I make a good bit of torque at redline even with the drop

The Greddy also requires getting rid of your front bumper beam. I know they have a template for cutting it, but after you are done there is almost nothing left of it.

The oil system on the AVO is a plus in my book, once you bolt up their plate it's like any other system, just hooking up a few lines. And it uses an OEM solution unlike the electric pumps out there. The PTuning kit should really switch to the same mechanism since the pump is only about $80 from Subaru and you just need a plate to mount it to.

AVO is just a small turbo that's all, the Greddy kit is very similar since it uses almost the same size turbo. It's a good street turbo.

Both systems IMHO are overpriced for what you are getting in the kit.

Not just bigger for bragging rights.
Ball bearing, more efficient, twin scroll, quicker transient times, name brand turbo for sponsorship reasons, etc etc etc
Locked in with that turbo for me, is a limiting factor.
But, as I said before, its tue closest ots setup that would work for me.

:popcorn:

As mentioned earlier, the SBD kit is nearly a complete solution with similar power and delivery as both kits. Sure, crash beam blah blah blah. You either worry or don't. We are all accepting risk when we mod our cars.

The SBD pros are: billet wheel 20G, bov, boost control, good base map, excellent support, short piping and price.

Cons? No ECUTek license or cable, but you can just borrow a cable and buy a license. No gauges, but a P3Cars gauge and wire in a wide band O2 and you're set. For some, the modifying or removal of the crash beam us a sore spot.

I have been running my SBD turbo for a little bit on stock everything and 91. The most it made on 10psi was 278 and lowest on 8psi it was about 248. I've lined up with a few fast cars for little bits of street fun and the car is surprisingly quick. This past Sunday at Import Face Off I ran a 13.7 @ 102mph with a 2.1 60'. It was consistent 13.8 ET and 102mph traps. I'm admittedly rusty and the lack of launch control made leaving a bit tricky.

Flex fuel is also coming down the pipe and an oil cooling solution is already on the table. These are exciting for me! I can't really comment on the AVO but I'm not a fan of a scavenge pump.

Did I miss where this thread turned into an SBD pros and cons thread? We all have our favorite turbo kits, but we didn't do pros and cons for them in a thread about the AVO and GReddy kits.

I forgot to address this. Clutch yes, brakes no. The OEM brakes will do just fine on the street. If you are planning on going to the track then I would consider an upgrade.

Free forum? Or did I miss something? I know I learned some new options and better solutions by getting great advice or a simple heads up by doing a lot of reading on this site.

If you don't look around or get an interjection from others, how do you ever make an informed decision? :search:

Oh wait, now I get it! King trumps Boss every time! All hail the king! :cheers:

My bad. ;)

The title of this thread clearly states AVO vs. Greddy.

Why did you derail the thread?

Don't you think he already looked around and decided on the AVO and the GReddy kits as his two favorites? Remember as we have been told multiple times by multiple people, the GReddy and the SBD kits are not the same. Also, don't act like you are impartial in your review of the SBD kit. I mean your whole post was an SBD sales pitch. How are your drag racing times relevent in a GReddy vs AVO thread?

I would just recommend better pads and maybe SS lines for increased pedal feel and confidence in stopping

.... I did look around. And from the layout and setup of both I had decided on those two.

I also factored in which shop will be doing the work next to me and they have experience with the two kits I made this thread on.

I made this thread to narrow it down to those two.

cheap cost to produce doesn't mean cheap price for consumers ;)

The Cheap comment was meant to be relative to the GReddy kit.

Uh oh! I knew it!

sure. and my comment can be applied to both. relativly to msrps... :D

I paid just a little over 4200 USD for my AVO kit, their BOV and a new filter from them. I do not feel let down by that price at all.

Why would you turbo your car if not to get more power/acceleration? That's why I tossed in some 1/4 mile info. I never mentioned anything about similarities of kits, just that there was another solution in the same price range with more goodies, similar sized turbo and such.


Also, I was considering a GReddy kit, an Innovate blower and AVO kit about six months ago. I decided against all because my BRZ is my daily beater. If I mod it, it will become another project, so no more mods was my reasoning for not doing anything. That was until I received an offer I couldn't refuse.


Sure, we're all different and we do things because we want certain aspects of our car enhanced. Sorry, OP, didn't mean to be a ****, but sometimes those of us who're happy would love to share what makes us happy. :)

Not to be a **** here, but you already modded the aspiration of the engine, and added coilovers and exhaust, it's already been a project for you? I mean the way you kinda wrote that implies that the Greddy and AVO kit aren't meant for daily drivers, which is the exact opposite...

I understand why you went SBD because you got a deal on it, that's great and all, but unless that applies to the OP, which I don't think it does, then the OP can rule it out based on what he previously said, his tuner knows the Greddy kit and AVO kit. We aren't bashing your advice in general just your SBD advice. If you have advice on the other two kits, by all means share :)
