Any commentary?

I don't know if its lighting/viewing angle, but the wheels look damn similar to me. Is the main difference in the housings?

the overall wheel diameter of the intake wheel is almost exactly a quarter in in diameter. The blades also are about an eight inch taller.
The larger wheel also has a more aggressive sweep to the blades.

The exhaust wheel is at least a quarter inch wider, and about again, a quarter inch taller.

This should be good for 350whp I think.

It's so unfair how the Evos have a larger turbo and yet have a lower boost threshold than we do running the TD05. The last time I was in an Evo it was like TD04 response with TD05 power.

and our cars still kept up pretty good with the evos!

I'm digging for compressor maps for the exact part number s16g we have. I doubt there is one specifically for it though.

Oh wow. I knew the evo3 turbo was better, but not by that much.

Think that cartridge would fit into the Subaru td05 housings?

That's what happens when the turbo is 6 inches from the exhaust valve.

you have to convert it to 90* inlet, is that your issue?

I wasn't looking for 90 degree. I was trying to find a straight inlet and thinking about intake risers like superdave. The only thing I found was the compressor wheel for something like $170. Is there a complete turbo available? My dream one day in the distant future is a larger turbo. But that will come after a stand alone.

There is the option for the Kamak cover and wheel.

I put this together using a hodgepodge of parts.

I much prefer the 90* inlet.

I do like the response of our Evo. It's actually my goal for my mr2, to be that smooth n powerful. However, despite what feels like dog-slow spool in my WRX (stock 16g-td05), its probably faster than the Evo with less mods/same boost. (granted a bit less weight)

got it installed

impressions:
much louder in vacuum conditions
increased rumble
much better manners
hard to get out of vac

not too slow on 10psi. Obviously the small was quicker at post 18psi levels, but the evo3 really shines as it reaches 20psi.

will be doing some road tuning tomorrow. fwiw the targeted afr for 12psi on the small was 11.4, and for the evo3, it was like 12.3. BAD. I only did that for a reference point of course.

what pressure are you running?

an evo3 is superior to the 18g for a street, pump car. Everytime I read on here or in person otherwise, I want to choke puppies.

As soon as you spin those wheels past 20,21psi, the compressor takes off. Maybe that is your issue?

I'm currently at 21 with my ewg set around 19.5. I only want to switch for power but after reading, I'm starting to have a change of heart. I don't plan on AXin a lot nor dragging. It's mainly for street use.
