Hey i was just wondering if a porsche 911 gt2 engine could be swaped into a 2000 subaru 2.5rs since they are both horizontal, or has it ever been done?

well, I know subaru engines have been going into old porsche bodies for a while now. I assume the reverse is true, but I don't know for certian.

It would be fun but you'd better be a good fabricator to fit a flat-6, 3.6 liter twin-turbo engine into an Impreza. :p

I wonder how much one of those engines would cost and if you could even get one.

"It would be fun but you'd better be a good fabricator to fit a flat-6, 3.6 liter twin-turbo engine into an Impreza."


it would be fun, but i don't think you'd have to be too much of a fabricator to do it, would you?

But i deff think it could be done without too much hassel.

A close friend of my family in So-cal put a 911 Turbo (non-GT2) into a 71' 911 (think 911 Turbo fastness x a lot due to how light the old 911's were). If you are looking for a cheap(er) way to have huge porsche power in a light weight car I would highly suggest that direction.

do you just have a $40,000 porsche engine lying around?

I think the motor is more than $40K... they're somehwere along the lines of $60K. And the gearbox is about $20K!

As for possibilites of a swap I think the porsche engine is way too big. Have you ever seen a Porsche flat 6 on a stand? It's a very big motor. It's wide and with the big ass turbochargers from a GT2 you'd have no room at all in the front of a Scoob for that thing. It's a lump!

That said, since we're most likely not taking budget into account... how's about an 05 Legacy wagon with a Porsche 911 GT3 drive train- and I'm not talking about the front of the car either. Try and think about a Legacy wagon with a GT3 (or GT2 for that matter) engine in the back, the whole rear suspension grafted in to the Scoob body shell (with the wheels sticking two feet out??!!) and all the radiators, battery and whatever else you could get up front for ballast. Could be scary.

There is a tuning company that did a VW Eurovan with a rear mounted RUF Tuned 911 Turbo engine and AWD drivetrain. Something like a 550HP Eurovan. Totally Bonkers!

It will be backwards :p

The other consideration is the Subaru drivetrain torque capacity. It won't withstand the torque output of the GT2 engine for very long unless it's driven with a light throttle foot almost all the time.

It's fun to speculate on a possible swap/conversion but I think this would be a very mismatched choice to go into a suby.

I highly doubt a Porsche 6 cylinder will fit in the engine bay. And it would only go fast in reverse. :p

I think it's all a fun fantasy. A GT2 engine would probably tweak the unibody of any Subie in to a pretzel, but it's sure fun to think about!

The shop I worked for did several interesting swaps, like a Triumph TR4 w/a Ford 302 sporting webers and GT40 heads. An Austin Healey 100-6 with a Chevy 327 and a Doug Nash 5 speed. Both of those cars were highly interesting when it came to chassis flex. But surely entertaining. But my all time favorite was an Audi TT Spyder running a 24V VR6 and two massive turbos. We only really rebuilt the gearbox for the customer, but it was totally insane. Something along the lines of 500hp and 480 ft-lbs of torque. And it all looked stock.

There's a bit of engineering advancement from Austin Healeys and Triumphs to Imprezas. Some Imprezas (like ESX's for example) already put out far more power and torque than an off-the-shelf GT2 motor. I still think it would be pretty damn cool to see that motor in a WRX, but I have my doubts that it would be possible without some creative persuasion on the builder's part.

I imagine that this would not be that hard for someone with a lot of time and money, and good engineering skills.

However, something that is often overlooked is that swaps like these, people who could afford it would rather just buy a real 911 turbo.
For example I remember this ricer posting on a porsche forums about the skyline and how it compared to all the uber-expensive exotics, and a 911 turbo owner made the truest comment ever:

"If the skyline is so cool, why do you think people with that kind of money (100+ thousand dollars in cash lying around) don't buy them?"

By the time you figure it all out and finish paying for it, you may as well have bought a GT2. If you could plant the engine where it would normally go and then put the turbos either towards the top of the engine or infront of the engine instead of the sides, and pipe the exhaust under the engine. For an intercoole you could try the WRC set up or somehow fit a top mount (I don't think frontmount would be very feasable.) Get rid of AC and put the battery in the trunk so that a radiator might fit in the front. Maybe a remote oil filter. A tough case and gearset would be a must, I think beyond even that of an STi. You would probably want a porsche tranny. About 100grand later you might be ready to hit the road in your new badazz Porscharu WRGT2.
