What if you put a 4 cylinder turbo (say....ej22t...... modded) engine and a 5 speed tranny in a SVX? How much lighter would it make it? Is it possible? What do ya think? I think it could be cool.

I think almost anything with a turbo is cool....

It is possible, and it would indeed be cool

You'd save a little weight. . . but the chassis of the SVX is where the real weight is. If you can figure out ways of reducing the chassis weight, then you're golden.

But yes, slapping a WRX engine in there would certainly make it go faster. . . and with all the engine support on the aftermarket for said powerplant, you can easily build it up for even more power.

This is Laurel's plan for her 91 Wagon. Not so much the weight savings over the EJ22, but more for the factory turbo and 5-speed that bolts up to it.

Custom motor mounts are a given, but such a feat could be done. The legacy transmission will bolt in to an svx, indeed a variation of the turbo automatic is already there. You would need different driveshaft, matching legacy differentials, half a slew of ej electronics, the aforementioned motor mounts and probably transmission mounts, and probably more.

That said, the outcome probably wouldnt be too favorable either. the 3600 lb svx is still a fat pig with the ~100 pounds out of the engine, and all that weight is gonna be a pain to lug around in non-boosted territory, and hard on the turbo in boostland. The spiffy gearing that allows the SVX to go so fast (and kill wheel bearings) is going to be gone, not that you'd want to work a turbo like that, and the weight savings becomes less favorable as the speed increases as well.

Fortunately, Subaru builds a chassis already suited for turbo gearing that the ej drops right in to. Its the legacy/impreza line.

Leave the SVX to what it does- go really fast. For that, a big N/A engine is gonna last longer and the weight is less important.

A breakdown of weight in modern cars finds more and more weight being found in the Goodies: A/C, Leather Seats, Soundproofing, Climate Control, ABS, 18 airbags, etc. How come do you think they now have ALL aluminum cars that weight the exact same as their much more "steelie" predecessors (ex: A8)? They keep putting more and more weight into personal comfort. I don't know where the weight is in the SVX... someone should strip one down and keep weighing it in the process. If it is the frame itself, there really is no hope for it. You'll just have to wait for Subaru to come out with an H6-T and the tremendous amounts of horsepower that will come with it to drop in.

Ooooh. . . . H6T


Again, we REALLY need a :drool: smily. . . .

Exactly, A 2.0L turbo in a 3600 lb SVX would make it an absolute dog to drive around in the city. The only cure is to turbo a big motor in order to get an appreciably even acceleration curve, such as the 3.3, or drop in one of the rumoured subaru flat six turbo's that are to arrive. For $4500 there's a turbo kit for the svx, it produces 60-80 more hp on 8 psi they claim, and its not intercooled. Apparently thats all the SVX motor can take, so intercooling it would be usless due to the fact that at that point the turbo isnt producing any significant heat. Now what would be cool would be to get forged internals, lower the comp ratio to 7 or 7.5 get the block welded and made closed deck, twin turbo charge it, and throw in a 6spd dog box, and you would have one twisted SVX

whoops it only does it on 4-5 psi not 8, my wrong

Mark,

Completely off-the-wall thought, but wouldn't a Porsche flat six fit an SVX? Obviously it would need some nifty work on a tranny adaptor but you could then have a 3.6 litre Turbo putting out 400bhp plus! If you could somehow mate the Porsche manual 'box to the Suby transmission then you'd have one heck of an SVX!!!

They put subie engines in old porsches and volkswagens a bunch. Sure, why not the othe way around? Same type of clutch and everything.

Anyone remember the SVX engine in the VW Vanagon??

Yeah!

There's a few sites with Suby engines in VW vans. I'm just waiting for the day when I see someone put a WRX engine in a Porsche...

I think Laurel would be interested in a 400HP flat-6 for Ruby.

What about the guy that put an EG33 in a Legacy, and then supercharged it. It did look like 10lbs of crap in a 5lb bag. Granted you will always get more power out of more cubes but I just don't think the work involed was worth it in in the end, but I would love to have a supercharger in my SVX.

Hey subafreak, I noticed you have a 5 spd SVX, . What tranny did you put in? Did you get that kit that small car performance makes? Or did you go into it all yourself?

Thanks,
Mark

It had the tranny from my 91 Turbo Legacy in it but then I split 5th gear so I got another 91 Turbo tranny ( very hard to find, cost me $600). I did the whole conversion myself. It's got an ATC clutch and custom short shifter. So far I got about 10,000 miles on it and all good, really hauls with a five speed but you still have to be gentel.
