I am not sure, never measured it and probably won't because I don't drag the car. This is my daily, don't need a broken transmission.

why would u buy an 18g if you don't even plan on beating on your car? Why would u even buy a wrx? 6 speeds are bulletproof, 09+ 5 speeds are almost bulletproof. I could see it if you had an old bug eye with 150k miles on it but damn...
I launched my 09 and my 11 at 5500 rpms with an ACT HD clutch, never skips a beat

Slow down buddy, just because I'm not going to drag the car, that doesn't mean I'm not going to be involved in other types of racing. I plan on road racing the car once or twice a year. And why would I want to beat the **** out of my only means of transportation? You can still have fun with an 18G without abusing it. I have faith the Forester transmission could hold up to a beating, but at the end of the day I drive a Forester, not a WRX. Not everyone has the same driving style.

My Fox is my DD, stock trans, 85K miles, there is nothing wrong with hooking up the APV2 and measure 0-60 and 1/4 mile. Just find a flat straight road, it is always useful to take before and after readings before an upgrade.

Learn to drive. My old 18g setup (my former s/n is CoolRex btw) ran 11.7 @ 122mph. Don't mind the 11.7 but the 122mph was nothing to sneeze at. And all of that was on a bone stock EJ205 engine.

My 18G Forester vs. typical stock sti on the same dyno:


My 18G vs. My stage 2


I would be making a good amount more power with an aftermarket intake and catback.

Here's a thought...

You need to just buy the 18G-XTR and post in this thread to make fun of me when you make more power and spool faster

Good numbers! I am still not decided if I go XT or XTR though... Neither if will go 8 or 10 cm. And Blouch did not reply to my PM, tweet nor e-mail

why would you go XT when XTR is now available, $150 differential is not an excuse when you are going to enjoy this turbo for several thousand miles with better spool and reliability due to ballbearing.

That was my minding before Yeahdudebrown raise the point about turbine housing size and spool up might be equal with XT and XTR. I might wait until you get the XTR tune

If it spooled exactly the same, I'd still take the R over the other. There are many more things to turbocharger dynamics that just spool and power capacity.

The larger wheel means the opening in the housing is larger. This means less backpressure which means more reliable engine operation as well as the gain in turbocharger reliability.

So your suggestion would be 18G-XTR 10cm?

turbine volume depends largely on your setup.

if you are on factory cams, I would not run a 10cm2 housing. I would run the 8cm2.

with the turbine housing you have to take into account the amount of flow it is going to see and then balance power, spool and backpressure to get the right one.

In general:
2L with factory cams: 7cm2 for faster spool, 8cm2 for more top end.
2L with large cams: 8cm2
2.5L with factory cams: 8cm2
2.5L with large aftermarket cams:10cm2

The displacement and the amount of overlap are a general base for how much turbine housing flow you need to sustain. However, if the max a turbo can produce isn't enough to outflow the 8cm2 housing, there isn't much point going to a 10cm2 housing. With that in mind, I would have to see maps for the compressor and turbine for the 18G, but I can't imagine a 10cm2 housing would ever be necessary on it. 10cm2 is a big housing and if you need that big of a housing, you should probably be on a bigger turbo in the first place.

Information like this is exactly why people still have hope for Nasioc. That's the easiest to understand explination of that i have seen yet.

Good stuff...and agreed.

Thank you so much! I can finally sleep and dream of my 18G-XTR 8cm^2. Can't hardly wait for my bonus and tax refund
