Over the next couple of weeks (if this kit doesnt sell), I'm going to install it on my IX and compare it to my current graphs.

I've got a baseline with my supporting mods - on 93 and on C16. I have changed nothing since my baseline (except maybe the ambient temps, obviously). I've heard this turbo will not produce more wtq than the IX turbo. Which I am sitting at 381wtq on a 1to3 C16 mix and 26psi, stock turbo.

So maybe we can finally get some hard number on how this kit performs.


HOWEVER!@
I located something on the ATP housing that could be a problem. I port matched the gasket to the turbine foot and, needless to say, there is a huge issue.

Sections of the foot dont match the gasket - I'd say maybe 10% or so. I'm going to grind these out today.

Any thoughts? Could this be part of the problem?

 

I strongly suggest you buy a new OEM gasket and throw that paper POS in the trash.

It will fail on you within 3 months, I promise.

^listen to this guy.

 

I thought most of the problems with that hotside were due to the turn the exhaust flow has to take after entering the turbo.

 

I plan on throwing away the crappy Megan gasket - without a doubt. I used it as a template for the port matching.


The housing now matches the header. Some backpressure should be reduced now. Has to be, actually. There was a lot of foot material there.

AFTER

 

not bad work at all. what kind of bit/rotary file did you use? or was it a sanding drum?

 

I used el'cheapo metal bits from Lowes with a Roto-zip. Took me approx 30mins. I rotoated b/w 3 bits to keep them from overheating. One of the three was angled (cone shaped).

I'm going to send the pictures to ATP.

 

dont forget to gasket match your manifold if you havent aready

 

can't wait for the numbers!

this is one of the things that i am thinking of doing as i want to keep my EVO stealth, especially in the turbo section and i am not looking to go crazy numbers!

 

BR kit will look stock with stock heatshield or another route is 20G-9-5.

 

Vishnu kit with adaptor plate looks stock as well......

 

What is the point of having the twin scroll manifold when it converges like that at the turbo?

The 3076 is not a twin scroll turbo... The stock turbo is.

 

This will be interesting.

 

Durrrr, at least in this case, but I am going to assume he is going to be using a twin scroll exhaust manifold, by judging the design of the gasket and hotside/housing.

You can have a twin scroll 3076..... so to say it is NOT a twin scroll turbo is incorrect, however this is a regular t3 housing
