Subaru with Porsche Flat 6 engine Hybrid

Kevin Thomas · 04-19-2002, 04:55 AM

This may have been answered a million times over but is it possible to swap a Porsche flat-6 engine into a Subaru?

Weren't you destroying tranny parts with the 2.2L in your OBS?

And you want MORE power?

proecm · 04-19-2002, 09:34 AM

Subaru already did that: XT6

.

Kevin, you should know this.

Anything can be done with enough money, I have seen a rotary powered Subaru before.

PeterJ · 04-19-2002, 11:36 AM

It is possible. There is a thread on it in the aftermarket forced induction forum.

You can NEVER have enough power!

Kevin, I like the way you think!!

i was thinking this the other day myself, along with a GC8 WRX hatchback...somehow grafting the rear section of a wagon on to a coupe.\

the only problem i forsee is that any porsche engine that would be economically feasable would be aircooled...i some how doubt there's a bunch of the new watercooled ones laying around in junkyards.

I was thinkin' bout doin that too.

I don't like the idea about the porsche engine though...
expensive oil changes.

I'm looking for that thread now. If you can find it, please post the link. Thanks!

*sigh* This madness must stop.

Pro ECM - Dave,

Yeah! I like the XT6's engine but the power is beginning to......bug me. I went through a whole bottle of nitrous last night and it just didn't feel......right.

Time to toss the 55 shot for a 75 now.

Zex needs to come out with a direct port setup....NOW.

Siper2 · 04-21-2002, 12:03 PM

Bah, put all the power you want in there if you have the money. Life's too damned short.

Just be sure to get some MRT hardened gearing stuff, and a Stage 3 Cobb transmission/drivetrain setup, and you'll be happy as a pig in.......

Thanks for the suggestion. Autotranny is already built up by Benchmark Transmissions, with a valve body. So this pig is pretty happy. Oink, Weeeeee!

my friend told me someone put in the 944 turbo engine in a GC8 before. he said he saw it in some magazine.

That doesn't sound right. The 944 is an inline 4. I doubt there would be room under the hood of a GC8 for it.

bobjr94 · 04-21-2002, 10:31 PM

why not just use an svx motor ? it will bolt right in..you just need to fit the rad up under the grill...put on a turbo and 350hp is easy to get...you can buy a wrecked svx for 1500$

an xt 6 motor is only 130hp, same as an early 2.2..

Andrew · 04-21-2002, 10:55 PM

im not an expert on subarus flat 6 motors but IIRC the reason many people dont use the SVX motor is too thin of walls on the block. which would mean it doesnt have the potential to make crap loads of power without cracking.

I think you might be thinking of the 3.0L H6 in the new Forresters; those have the cylinders very close together, and probably won't hold up under any boost. But the H6 in the SVX (3.3L?) is a totally differnt beast, and has been turboed succesfully many times. But is that one able to fit under the GC8 hood? The Forrester one will, it's about the same size as the 2.5L H4, but I think the SVX engine might be too long. But I could be wrong on that, don't know a ton about the SVX engine dimensions.

Here's my plan, if my RS ever get's totalled in a rear-end collision (knock on wood). Buy the RS back, buy an Outback Sport wagon (the one based on the Impreza), and swap over the RS driveline/suspension/grill/hood/front bumper, basically anything that could be swapped over. VIOLA!! 2.5RS wagon! Guess that would be an old-school 2.5TS, huh?

In the early stages of this board (I-club), the same thing was said of the EJ25 engines as well. All the talk of the open deck and the cylinders floating and not being able to take any boost.

With the way things have been going on here lately, I wouldn't be surprised to see a Subaru Justy with a 125 shot of nitrous on it reliably. Ok, Ok....I got carried away.

XT6Wagon · 04-22-2002, 12:14 PM

I'm sure it could be done, but I bet you would be very happy with a EJ-20T driveline instead. A nice Legacy single turbo setup is cheap and makes decent power.

yes, that could easily be done, but what i'm talking about involves taking a coupe, and grafting the rear hatch section in place of the trunk. provided you could get rear side windows that looked right, it would be rad...i got the idea when i saw the reflection of my car in a window...the window frame combined with the slight curve of the glass cut things up just right visually that my car looked like a 2 door hatchback.

What H6 in the new Forester? The only Subarus in NA with the H6 is the Outback VDC wagon/sedan and LL Bean models. The 2003 Forester gets the same 2.5L with a rumored turbo in 2004.

From what i understand, the SVX H6 engine will NOT fit in a GC8 engine bay. It is too big, too heavy and will also throw the weight balance of the car off making it too nose heavy and undrivable, even if you did manage to cram the engine in.

The H6 in the LL Bean Legacy Outback is about the same exterior dimensions as the GC8 H4, but this is the engine with the really thin walled cylinders and the engine block won't tolerate massive increases in power, making it a poor choice for power tuning.

RageHardIntoTheBendies · 04-22-2002, 05:01 PM

the SVX flat 6 will fit, FAT has done it.
And it is not much heavyer than the EJ25, 30lbs IIRC.

Hondaslayer · 04-22-2002, 06:09 PM

The H6 is not much heavier than the 4. And if you can go w/o A.c simply remove the condenser. Custom fab a bracket for the radiator to be moved to where the condenser was make a few motor mounts upgrade your clutch and get some very nasty wiring out of the way and it can be accomplished. (SVX motor btw)
