what is the piping diameter on header and up pipe?

Looking forward to making you one! I think i PM'd you back on this - but it's 1.5" into 1.75 " after the merges.

Our website is going to a shopping cart-based system, so it's a bit torn up right now. Unfortunately we don't have any links to the A/W setups, but if you have any specific questions, shoot em via PM, or ask away. In the meantime, here's a pic from our latest Subie a/w project:

How much is the air/water IC system?

Is it on a custom setup only? or is it packaged to be sold as a kit?

I see you have it currently piped for the cast intake manifold is there any plans to make it work for the plastic manifolds and the VF30 turbos? (ie legacys/08+ wrx)

speaking of turbos i see it's currently for a rotated kit does it work with factory turbos too?

What pump do you use?

Is a heat exchanger used?
Is there a reservoir in your kit? If so where is it placed?
I see your kit uses the factory BOV, to you make it just vent to atmosphere? or is it piped back into the intake if so where?

Sorry to ask so many questions. but I LOVE the idea of air/water IC, and plan to do so for my car. There aren't too many companies that make them for subarus so it's awesome to see that you guys are doing it.

Moore Performance · 09-12-2012, 01:10 PM

Answers are in red. Thanks!

We like to do kits that are as complex as this as a "tuner" style kit - all of the hard parts are made to fit your particular vehicle, but things such as the lines will need to be cut to length and brackets might ned drilled/modded for your specific setup.

I see you have it currently piped for the cast intake manifold is there any plans to make it work for the plastic manifolds and the VF30 turbos? (ie legacys/08+ wrx)
We can make our current GD-style kit work with the plastic intake manifolds/upward facing compressor outlet. PM for pricing on this model.

speaking of turbos i see it's currently for a rotated kit does it work with factory turbos too?
we have both rotated and stock fitment (GD) models.

What pump do you use?
We use either SPX/Johnson (made in Sweden) or Davies-Craig (made in Germany) pumps, depending on the application.

Is a heat exchanger used?
Yes it comes in the kit.

Is there a reservoir in your kit? If so where is it placed?
There is a reservoir- it's located essentially where a cold air intake would go. It's roughly 3 gallons. It is not accessible for ice, unless the customer requests it as such (extra charge).

I see your kit uses the factory BOV, to you make it just vent to atmosphere? or is it piped back into the intake if so where?
The bov works just like a factory BOV, so you can vent it to atmosphere if you desire, or plumb it back into the factory location.

Sorry to ask so many questions. but I LOVE the idea of air/water IC, and plan to do so for my car. There aren't too many companies that make them for subarus so it's awesome to see that you guys are doing it.
No problem. Great questions! We love these setups too-they work really well in both street and track applications.

Sent pm about an hour ago so most likely I figure you haven't had time yet. Either way you mentioned pm'ing you about maybe some bigger diameter piping if I read correctly.

yes, we can upgrade the piping size to match your HP goals

We have to get one more car tuned before we get the GR back on the dyno - working on a few interesting things in the mean time - we'll keep you posted!

We're a few weeks out on dyno time to get this back for the bigger boost runs! Can't wait!!

NoMMitch · 03-18-2023, 11:37 PM

So I found the car on Facebook marketplace about 2 months and accidentally stumbled upon this forum when purchasing the car. It had 32K miles on the chassis and I'm assuming around 20K miles on the build. Unfortunately the car was never put on ethanol and the fuel system was left as is when I bought it. After buying the car I'm 99% sure it has a blown headgasket (overflow fills and throws coolant everywhere) and I'm about to pull the block apart to replace it. My next goal is to upgrade the shortblock while the car is apart so I can support my 600whp mustang dyno goal. I want to get a closed deck and am debating on upgrading internals. I'll be getting a dual fuel hanger (walbro 450s), bigger fuel lines and 2150cc injectors. This is my second STI as my 05 STI is my daily. I am super excited to get underway with this project, however it is a little daunting as it is the first time I will ever be pulling a block. I may be changing the turbo and going back to a FMIC as it is WAY too overkill to have the custom air to water exchanger on the car. Was curious if anyone who took part in this build was still on here and if they could give me any pointers.

Dave D. · 03-19-2023, 02:46 PM

Good choice to run corn this time. I highly recommend you upgrade your fueling to an under-hood surge tank. Much closer to the motor, better, more consistent supply (way fewer harmonics) and a reserve capacity for cornering and acceleration. I'm sure Kermit will chip in on this topic.

K3rm1tth3fr0g · 03-20-2023, 09:25 AM

Slapping FIC 2150s in with a dual pump hanger and saying '600WHP please' is a recipe for your tuner to dislike working with you

Many tuners will simply refuse to tune non ID injectors because of how much it sucks. The original build used ID injectors for a reason...

Injectors and fuel pressure are not as simple as: seems about right, so it's good enough.

Additionally, maintaining fuel pressure, especially when laterally loading the vehicle, becomes harder and harder both as the fuel level in the tank drops, and as power and load on the pumps increase, as you require more fuel pressure the more boost you run. This is where a dedicated surge tank as mentioned above starts to make a lot of sense.

user1029 · 03-21-2023, 11:59 AM

I switched from a radium surge tank dual pump to radium dual pump in-tank system. It’s nice having one less fuel pump and no longer having an exposed fuel canister in the event of a rear end accident. Plus I got my hatch space entirely back

I was worried about the adverse effects but for the past 10k miles on this setup, I haven’t noticed any fuel starvation/fuel pressure drop so far with 800whp worth of g’s

It certainly varies from car to car and chassis to chassis. The GD is a bit more prone as well. I know Killer B hasn't had much issue with the dual pump hangers, though IMO they are a sub optimal solution to combat fuel starvation and add additional pumps and don't replace a surge tank in function when pushed to the limits. Only takes one lean event to melt a piston.

Would be interesting to see a log of fuel pressure while cornering hard with

Would be interesting to see a log of fuel pressure while cornering hard with <1/4 tank of fuel.

I had an aeromotive fuel pump fail on me 10 years ago since I was running on empty too many times. Since then I keep the car religiously above 1/4 tank

I'm sure not for a fuel tank in the engine compartment. I doubt it is legal for any racing organization.

You might be right. However, I'm comfortable with the small enclosure in the front of mine which doesn't take up much more room than the pump that fits inside. A popped fuel line under pressure would probably put more fuel under the hood in seconds.

We made a fueling mistake once. It's an expensive lesson to learn. In our GD we switched to baffled and matted fuel cell with dual Bosche 044 pumps. It worked flawlessly, but was VERY expensive.

More recently we use the big OEM fuel pumps, they work great and have been rock solid reliable. It's a Hellcat pump with a Visconti Basket Upgrade, all E85 compatible. We've used this on a few cars without any issues. We do however outflow the 'jet-pump' in the tank so whenever there is dyno testing, mountain road blasting, or Auto-X, the tank gets topped off whenever the level drops below 1/2. If you were considering track use with slicks, cage, etc. then a surge tank or fuel cell is good insurance.

Real world experience always wins over general supposition.

Smart people only fuel starve once

NoMMitch · 03-23-2023, 10:02 AM

So after doing plenty more research (I've doubled and trippled down on research for the past year) I really have been debating between the 6466 and the 6870. The other thing I'm looking at doing is a bigger Injector. It's really hard because going from 1700s to 2600 is a huge jump and I don't think my car will be able to drive on 93 hardly at all if I ever need to with 2600s. I'm curious what you guys think spool difference on the two will be. I'm keeping the cosworth heads and selling the shortblock more than likely and going to outfronts ultra shortblock. I've seen that the 6466 1.05AR has made really decent power at lower boost applications but I don't know the limits of the 6870 and if it's going to be an unfun street car. Regarding fueling I still think a double pump in tank setup is the safest and makes the most sense from a simple is better standpoint. Of course I don't want to lean the car out but I've seen tons of Subarus running the double pump setup at high hp.
