In this video I give you 3 reasons why the 2003-2009 jdm Legacy GT is the Best Subaru by far! EJ20Y
My Legacy:
2004 JDM Subaru Legacy GT 2.0 twinscroll turbo BP5 WAGON
5 speed MANUAL
Mitsubishi TD04 HLA 19T turbo (OEM for the ej20y) (ej20x has the vf38 for 2004)
These cars have Dual AVCS which is basically Subaru’s form of (Honda) “vtec” with a change in camshaft profile (INSANE!)

Based on the same engine platform; the X designation indicates an automatic package, and the Y designation indicates a manual package. The EJ20X engine was introduced in the 2003 Legacy GT, mated to a five-speed automatic transmission, and the EJ20Y engine was introduced in the 2004 Legacy GT, with a five-speed manual transmission.
The EJ20X and EJ20Y are open deck engines whereby the cylinder walls were supported at the three and nine o’clock positions. It came with an aluminium alloy block with 92 mm (3.62 in) bores - with cast iron cylinder liners - and a 75 mm (2.95 in) stroke for a capacity of 498.6 cc (30.43 cu in) per cylinder, with thicker cylinder walls than EJ25. The crankcase for the EJ20X and EJ20Y engines had five main bearings and the flywheel housing was cast with the crankcase for increased rigidity. The EJ20X engine is understood to have a forged crankshaft and connecting rods, but cast aluminium pistons with forged crowns. The EJ20X and EJ20Y engines had an aluminium alloy cylinder head with cross-flow cooling, double overhead camshafts (DOHC) per cylinder bank and four valves per cylinder that were actuated by roller rocker arms.
The EJ20X and EJ20Y engines were equipped with Subaru's ‘Dual Active Valve Control System’ (‘Dual AVCS’) which provided variable intake and exhaust valve timing. The Legacy GT, the EJ20X engine was fitted with a twin-scroll IHI VF38 turbocharger; the EJ20Y engine, however, had a larger twin-scroll Mitsubishi TD04 HLA 19T turbocharger. For the revised BL.II Legacy GT, both the EJ20X and EJ20Y had an IHI VF44 turbocharger for the initial 2006 model year, replaced the following year with the IHI VF45.
Both came with a 9.5:1 compression and a fast spooling turbo yields a torque filled performance. 265-280 bhp (198-209 kW; 269-284 PS)
Turbos:
IHI VF38 (automatic, 03-06)
Mitsubishi TD04 HLA 19T (manual, 03-06)

HERE IS A FORUM OF THE LEGACY MAKING 300WHP STOCK TURBO: legacygt.com/forums/showthrea...
(Wouldn't that make the td04hla-19t the highest flowing oem turbo that Subaru has offered?
That flows more then the VF36/37 and people get over 300 whp out of them.... Why hasn't there been more talk about this turbo?
It looks like even has a titanium wheel...)
(Saw you post after posting mine above. Nekdut is running the Mitsu with 18g wheel, pm him for more info. I am not positive about the 320 whp mark, but 300 whp I would say it's safe bet - that's what vf40-18g hybrid can achieve.
This turbo will for sure have better bottom than JDM STI turbo and respond faster -ergo, fatter powerband. Fat powerband is what makes a car truly fun to drive, not crazy top end only...
You can get avo tmic that fits that turbo or any fmic. The flange is located slightly different but that usually is not a problem with front mounts (avo fmic is designed with both).)
