Greddy vs avo stage 1 Pros and cons of each

[Crazy Drew]

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.

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?
