Turbo specs?

[GGMazda]

Hey guys! I came across a turbo from a 2010 Mazdaspeed3. It's the stock turbo from the DISI 2.3l, but I know nothing about it! I'm wondering if you could help me out with some basic questions. Keep in mind that I know NOTHING about turbos, and just a bit about Mazdas...

1 What kinda boost does this thing provide?

2 I remember reading something about common failure on this. What should I look out for if I run it?

3 What kind of injectors will I want to run? What's stock flow on the car?

I have a friend helping me install it. (See; he's going to be doing most of the work lol) and while he's pretty good with turbos, he doesn't know the first thing about this one.

What are you installing it on?

Are there numbers on the side of the turbo?

Ok, FYI, this is how trolls usually try and troll forum, so don't expect warm reception.

It's a k04. Do a google search about k04. It's a turbo. It uses exhaust flow to spin turbine which spins an impellor on intake side. This results in an increase in air pressure going into the cylinders over barometric pressure.

Not a troll! Just a severely uneducated Mazda newbie.

We're installing it on a Toyota 1NZ-FE. Yeah, I know. It's just my learning engine. It was free, the turbo was free... why not?

K04, that's what I was looking for! I know how a turbo works, lol. Just not the particular specs on this one.

It's a L3YC-13-70ZA. Not sure if there are any numbers on the side; haven't unboxed it yet.

Even with what has been discussed in recent posts, I feel the need to be a really harsh ass hole to this one.

1NZ-FE is a Yaris engine...

It's just a running engine on a stand

It's a fairly common upgrade in the VW/Audi world, on their 1.8L engines.

Stock K04 specs are as follows:
Compressor: 60mm exducer, 58.8 trim
Turbine: 50mm exducer, 79 trim
16.5 A/R -- This is surely a mistake; AR should be near 1.

"Power balance is supported by a 79 trim 50mm turbine stage with an Inconel shaft-wheel mated to a 16.5mm A/R Niresist iron turbine housing. Maximum turbine speed is over 165,000rpm with a peak exhaust gas temperature in excess of 990 degrees Celsius." 2007 Mazdaspeed 3 - Sport Compact Car Magazine

Also, please put ITBs on that thing.

Yeah, I've been drooling over those lately...
