Just need to be standard ethylene glycol mix but the subaru blue should be fine. If you are topping it up, you should check whats in there already. Being in the uk I was ut fitted at fensport? They use the subaru blue i think.

Yea Buddy it was fitted at fensport it just down by about 2".

It also do look blue in colour.

My OEM system needs topped up and just got a 1 ltr bottle (blue) i was going to top the the supercharger coolant as well. You think it will be ok?

Thanks Buddy

Adrian is correct we recommend any ethylene glycol mix so the standard Subaru blue is fine

1 minor point though is the performance of the intercoolers will be slightly better with a milder mix, so 25% anti-freeze to water gives a slight improvement in heat transfer compared to the 50/50 mix

Thank you very much Matt, appreciate it will add slightly more water.

That's awesome. Noticed they now have a 2015 WRX intake. http://cosworthperformance.com/part/...-15-subaru-wrx I've been waiting eagerly to put Cosworth parts on my WRX. Any chance @Matt@Cosworth that you will be offering a tune for the 2015+ WRX soon?

Yup! Also today RallySport Direct did a live stream with Cosworth about upcoming things for the FA20 motor such as forged internals (both WRX & Twins) and other topics. It's on their Facebook. Cool fact: Rick from RSD answered one of my questions!

I shortened the length of the pcv hose and my 2.3 kit idles much smoother

Please elaborate on this

[TxFrs10]

The hose from the block to the left side of the throttle body. I made the path as direct as possible. The hose i had was about 8 inches too long and was looped. The idle at start up levels out much faster. For the first time after 15k i feel the true refinement in the stock tune. I did this as a result of getting a lean on bank one at idle. I could still have a leak in the system somewhere, ill be checking that soon. No fault codes so far 3 days in.

Interesting. I'll have to see how mine looks. I did have a running lean issue, but got that tweaked by Matt a while back. Though I don't know if that has anything to do with what yours was caused by.
