Just a question out of curiosity. Is the new Subaru 3.0 H6 the same engine as from the old SVX?

 

the svx, or at least some, had a 2.7 or 8 right? or was that the xt6? anyway, no they're not the same. the new h6 has a timing chain for one thing.

Thanks I was just wondering since I had heard that the SVX had a flat 6 as well and thought that Subaru might have brought it back, redesigned as the H6.

 

SVX was a 3.3l motor. The new H6 is a 3.0l

 

ahh, yes you are right rallykeith. i couldn't remember. the xt6 was the 2.7. they were pretty cool. even had a diff. lock. anyone ever seen an xt with a 4cyl. turbo...??? i've only seen two and they were in the junk yard. same thing as the turbo loyale though, so nothing really that special.

Well, I've seen a few of the turbo XT's on the road, but I own an 88 RX. Same driveline. 1.8 Turbo with the fulltime 4wd, locking center diff, and mechanical LSD rear. They aren't that easy to come by anymore, and let me tell you they are a ton of fun. The EA82T motor that came in them was only an 8 Valve, so it produces some serious low end power, 134 ft. lbs at 2800 rpm. Couple that to those locking diffs and a dual range 5spd and it is some serious fun in the snow or at a rallycross. My brother and I spanked some WRXs at a rally cross right after I got it. To be fair we got beat by a 2.5RS. I think the WRX guys we're trying to go easy on the car.

Anyhow, The XT6 was a 2.7 (ER27) and again was the same as the 1.8(EA82) but with two more cylinders tacked on. (1.8 / 4 cylinders = 4.5l per cyl * 6 cyl = 2.7l!) The pistons are in fact interchangable between the 1.8 and the 2.7 XT6 except that the turbo pistons were lower compression(Makes it easy to make a high power turbo xt6). Same went with the 3.3l (EJ33) SVX motor. The pistons in the 3.3l were a higher compression version of the 2.2l(EJ22) motor's. You can build a high compression 2.2 using SVX pistons. Subaru really has done some pretty cool things over the years though. I'm glad to see they are finally bringing back all the cool stuff for the STi!
