Default EJ20 in a SVX?

My friend is looking at a SVX with a blown tranny and I told him it can be converted to manual with a Impreza tranny. Plus he wants to be able to mod it and there isn't a huge aftermarket for that motor, so has anyone tried putting a EJ20 in a SVX?

the tranny idea is good but the ej20 idea is dumb.
the eg33 has so much more then the ej20 will ever have. tell him to work with the 3.3 first, get creative with it first dont just throw it away!

Yep, the trans is great. Our shop had done a WRX trans in a SVX conversion and it worked out really good. But the car is really heavy, you won't like the 2.0 in it!!

I think it would a lot easier and cheaper to get big power from a EJ20 than the EG33. How many 400hp WRX's are running around and how many 400hp SVX's are running around? The USDM EJ20 is 227hp@6000/217trq@4000 stock and the EG33 was around 230hp@5400/228trq@4400 stock, so where's this huge power difference? I think with just a turboback the EJ20 would surpass those numbers. Sure off boost the EJ20 would suffer but I don't think he would be off boost much the way he drives. I'm not trying to start an arguement, just trying to get educated.

That sounds like a lot of work, but I can't think of any reason why it shouldn't function in the end. However, you'd need to do a lot of custom fabbing, and in the end you'd have something that is still unproven in a large GT car.

Sure there are 400 HP WRXs running around, but if you try that in an EJ20 powered SVX, you have another couple hundred pounds to deal with, which means you will definitely need a stronger transmission.

Anyone who can install an EJ20 into an SVX and make it work well might better spend their time building up the EG33. Maybe I'm saying that because I want more power in my own car

uh ..
there are zero parts for the eg33..

it will be alot of work but not much more than a standard usdm swap into a non obd-2 car
only REAL issue i can think of is the intercooler ... front mount i guess

i considered an SVX for a project ..
the expensive part of the manual swap is the custom lengthed front axels and chaning the ring and pionon in the rear diff to match the front.. .. the best solution is to weld the center diff and make a RWD car .. this should hold more power befor it blows up too

Lengthening isn't necessary, and if you use a USDM WRX tranny you don't need to change the rear diff ratio.

Just hoping such facts will let more people take the plunge

You go alex!

I'm quoting this to drive home the facts. Axle shafts match up perfectly to the WRX 5 speed that I'm using. The USDM SVX also uses the 3.545:1 rear diff ratio used in the USDM WRX. No changes required.

Thanks for the backup, Todd!

As for the front half shafts misconception, maybe this stems from the need to extend the driveshaft to the rear differential. When you have the two piece driveshaft this isn't too big of a job, really. Cost me about $60 for that lengthening.

fwiw...

I guess my mian question was would the EJ20 match up to the mounts and all I figured wiring would be a pita, but I knew the aftermarket for the EJ20 is 1,000 times bigger than the SVX. Plus my buddy is the kind of guy that likes one of a kind cars.

I would say to buy some low compression pistons and turbo the EG33, yes I know ALL about the turboing of SVX....I'm a memeber of www.subaru-svx.net
a lot of the guys on the board are to worried about what "could" when it comes to turboing....no ingenuity...or engineering
Take it easy, Micah

the cost of an engine swap for the wrx to svx conversion would be probably about the same as having a custom turbo setup done for the svx, around 5-6000 dollars

so, he has the option of having a 350hp 6cyl engine, and 5mt or a 227hp 4cyl engine w/ 5mt as a starting point

sooooooo

i dont' see the money savings here at ALL

spend 6000 to start at 3hp less, and a much peakier torque curve, w/ more aftermarket
or start w/ 350hp and less aftermarket

and the 'lack of aftermarket' is a common misconception
the lack of ADVERTISED aftermarket is what there is

there is a company that does custom internals for the eg33, they will do pistons rods cams etc. for apparently not much more than doing the same mods in any car, and w/ nitrous on that turbo at a 50 shot you will have no problem meeting that 400hp goal

there are suspensions available, there are not sway bars availible at the moment, but they are in development and are apparently due out soon

and if your willing to order from japan the market increases a LOT

Yeah all you will need is a custom turbo kit, hood or bumper for the intercooler, low compression pistons are reccomended, and at least a piggyback for air and fuel....engine management would be preffered...so one has better power if willing to do it correctly.
Just weigh the pro and cons for each.
Take it easy, Micah
I would love to keep the H6 if possible though

I don't know how many times I can address this issue about an EJ20 going into an SVX and being a "good Idea"... It isn't... But hey if ya wanna try it, go for it... If you have the money and the time to custom fit the EJ20 into the engine bay then go for it... I would love to see a turbo 4 SVX running around... But if I were gonna do it I would put a Forester 2.5 XT engine in it... More displacement, more torque down low... I would compliment the engine with the Forester XT's tranny... I believe that this combo would be the most logical when it comes to swaping engines and drivetrains into the SVX... Now if your friend is gonna keep the EJ20 in boost all the time then hey, go for it... I still think that 3,580 (for the 1995 SVX L AWD) is alot of weight to move around by a little 2.0 turbo 4 cylinder... A fully loaded WRX weigh's as much as my SVX Without me in it!!!! That's a heavy car... Now if you want to build the EG33, there is a place that you can get High performance cams for the engine and titanium valve springs that should net you about another 20 or so Hp... It should also let you raise the redline to about 8,000 or so... I do not believe in NOS, but there is plenty to do to the EG33 to make it go with a urgency... Ya just have to have money...

Hello guys,

If these places exist and are selling these parts, why aren't people mentioning who/where these places are? Is it top secret or something?

Sounds like Cobb is the place, although to my knowledge no one has actually installed anything yet. Here's a post from the SVX World Network: http://www.subaru-svx.net/forum/show...highlight=cobb

yeah that is what I had read on another thread over on the SVX forum...rods and pistons of a EJ22 will work as well.

Why does everyone think that the EJ20 is going to be so much of a dog in a SVX? The peak numbers are only 3hp and 11ft/lbs different. I know about how the SVX will be a dog off boost but who tries to be fast when there off boost. The WRX gets its peak torque at a lower rpm. The whole friggin' point of this thread was to see if a EJ20 would mechaniclly drop into a SVX with no moving of the mounts, fenderwells, or firewalls. I don't even want to argue about whether the EG33 or EJ20 would produce more power, because that is not what I'm talking about. I am saying it would be much easier to get 400hp from a EJ20 in terms of finding proven parts and cost.

So anyone that has tried to fit a EG33 into a GC or GD chassis did the mounting points match up.
