What TD0X-XX is the Blouch 1.5XT based on? I ask because the Blouch that Scary has is simply fucking awesome at getting up to boost early and makes bulk Hp. I see no reason of getting bigger. Albeit Scary's is crammed and is actually a 2.7l.

Edit - partially answering my own question, the 1.5XT is a Garrett based turbo with a 10cm exhaust housing. The TD05-18G on mine and Scary's is a 8cm housing. Larger housing suggests more lag and less response but better top end flow.

From Blouch:

Application: Subaru 2005-2009 Legacy GT and 2008+WRX
Horsepower: 400HP

The LGT-380XT is an awesome 400 crank HP bolt-on upgrade for your 2008+ WRX or 2005-2009 Legacy GT featuring the following:

Custom WRX/Legacy fitment compressor housing
Blouch billet 40lb/min “XT” compressor wheel
Genuine Mitsubishi center housing with genuine Mitsubishi parts
Mitsubishi TD05H turbine wheel and shaft assy.
7cm2 or 8cm2 turbine housing options
Complete with coolant pipes and oil drain tube installed and turbo mounting gaskets
