I'm in the process of installing one of these. They are the japanese forester motor. Just curious if anyone has had experience with one or has one in their car. Seems like a great way to go for those of us looking for a 2.5 in our wrx.

good luck man. keep posting, i'm interested to see how it goes. I'm planning on going the same route. where did you get it from?

JDM FXT EJ257 MOTOR
The JDM XT 2.5 EJ257 Engine makes an excellent swap for any WRX owner looking for STI performance from their WRX.
The JDM XT 2.5 EJ257 is essentially an identical engine to its brother the USDM STI 2.5 engine but at a much lower price. The engines feature a completely forged rotating assembly with hyper-cast pistons that is capable of safely withstanding an incredible 500HP.
Compared to the USDM WRX engine, the larger bore (100mm versus 92mm) and increased stroke (79mm versus 75mm) significantly increases the midrange power output and maintains a broad power band even with much larger turbochargers such as the Garrett GT30R. In essence an EJ257 all but eliminates the excessive big-turbo lag associated with the EJ20 WRX. Furthermore the increased displacement helps to increase power output even when using less than optimal fuel, such as California’s 91 octane.
The EJ257’s improvements (over the WRX) continue with the heads and valve-train. With a much improved casting, the EJ257 boasts a larger intake port size, larger compression area, larger valves, and of course more aggressive camshafts.
Given proper tuning and setup, the JDM FXT EJ257 is perfect for larger than stock turbochargers. On average with turbochargers such as a GT30R, we have seen gains of over 50whp and substantial improvements in the midrange power (reduction in turbo lag) in comparison (see graph).
Swapping an EJ257 JDM FXT into a USDM WRX is a straight-forward process. The intake manifold is simply switched over (along with injectors, rails etc.) and the engine is dropped in. The custom cam-position sensor (we supply this) is bolted into place with the factory cam-position sensor, and the FXT cam-position and AVCS sensors are left unconnected. ECU recalibration is required for this particular engine.
We offer in-house installation, setup, and professional dyno-tuning, including ECU reprogramming (Ecutek) and stand-alone engine management installation. Please contact us for any questions regarding our services.
ABOUT OUR ENGINES:
All our engines are inspected, leaked down, and compression tested. These particular FXT motors are all less than 1000km and are practically brand new. You MUST follow standard break-in procedures on these engines (500km). We offer start-up warranty on all our engines.
Shipping and crating is additional

I'm going to post on a separate thread under the "Subaru conversions" forum. I'll try to note any details and problems (hopefully there are none), and post some pics
