Well it does produce roughly 300hp and 300lbft torque... And those numbers are usually underrated as many people find out when they dyno their stock SVX...

As for putting one of those engines into an SVX, good luck with it. Yes, technically speaking it should "drop right in"... And it will bolt up to any Subaru tranny you want to put behind it (assuming that it is a 6MT or an Auto - unless you want to replace the 5MT alot)...

Wiring... This is the part that I would be scared to get into... Infact I had the opportunity to do this very swap back in 2004 when I had a little "bump" in the mountains... I had the $$$, I had the engine (well, hadn't bought it yet), I had the shop to do it and everything... But the one thing I didn't have was the guts to look at my baby get her engine ripped out and replaced my something that was going to make the driving experience VERY different and was going to get rid of the wonderful Flat-6 scream I have come to love...

I have driven MANY WRX's and STi's and I can tell you from experience that I wouldn't want my SVX to drive like that... The noise of the Boxer-4 just doesn't "fit" the SVX's beautiful lines... The power you would get out of the swap in the mid-upper RPM range would be AWESOME, but it would be nothing but headaches over time...

If you want to make this a track car / weekend car then by all means do it... But I tell you, go drive a WRX or an STI before you try and take on a task such as this... It isn't as simple as just dropping in a new motor...
