Post Question about crazy engine swap...

Ok. This could go in a couple of different forums, so I figured I'd post it here. Ever since I read a review of the 3.0L Outback I've had crazy thoughts of a 6 cyl Impreza. Anyone know if it's possible? Apparently the 3.0L is only, like 3" longer than the 2.5L, so it would be conceivably possible, right? Find a wrecked one, rape it for the computer, wiring, engine mounts, etc. Any comments? I mean, c'mon, 200HP in factory trim, add an exhaust and an intake, go rip it up. And it'd be damned cool to have a 6 cyl Impreza.

It's only about an inch longer if I remember correctly. Try searching the Powertrain forum as this has been discussed many many times.

Didn't someone engine swap it before and had some big problems? Its cheaper to just turbo the 2.5

The H-6 will add about 100 lbs to the front, causing understeer and making better shocks necessary. And the H-6 will only mate up with an automatic trasmission. Although, having that soup under the hood would be nice. And I thought it was closer to 220 hp, isn't it? Oh, well, it will be interesting to see what it ends up being like, as I'm sure someone will do it eventually. Just some thoughts....

So, if you get the WRX aluminum hood and the lightweight inner bumper beam, that would just about even out the 100 lbs you gained from the H-6, right? No manual tranny, though.

I would wait until someone else does it. Its much more expensive be the first to do this kind of swap. Take it from someone who is almost finished with a H-6 into a old wagon.

Andrew- I have a '96 Brighton coupe, only the 1.8L, so I'm entertaining all ideas. EJ20T, 2.2 or 2.5 with aftermarket turbo, EJ20T STi, etc. But I figure, if I'm looking at engine swaps anyways, why not check into all the crazy possibilities.

Only mates to an auto, huh? Well that's a bugger. Nothing will be happening anytime inthe near future, it'll be at least another 2 years until I have the car paid off before I go to those extremes. Also, the stock output might be closer to 220, I don't really remember. I knew it was at least 200, though.

Now, I'm sure there's people out there who are going to say "Just sell the brighton and buy an RS or a new WRX." I would, but that just means more payments, and bigger payments. Besides, I wanna see the look on RS owners faces when they get blown away by a Brighton!!!

XT6Wagon - definitely a good piece of advice. So how close are you to being done, now? I know you've been working on it for at least a year, now. Like I said, though, not for another 2 years or so, so by that time hopefully someone will already have done one!!

I have a silly question.... With the H6 ~220HP (even in an outback) can you lay rubber on the street?

I'm just curious because in my dad's Toyota Solara (sweet car, but handles like a boat) I can lay about 20 feet of rubber in 'D' (auto tranny) if I try really hard. It's the SLE V6 with around 230HP.

I'm really wishing subaru would give us some better performing engines, but I guess they are working on it with the new WRX. Speaking of which, can you lay rubber with the new WRX? I would think the AWD system would negate most wheelspin, but a 4WD burnout is a very cool thing to see.

I think there are a few problems related to the H6 engine swap

1. too heavy for Imprezas, or probably even for a Legact GT

2. the intake is too high, you'd have to cut a chunk out of the hood to fit it right unless you spend $5000+ on a custom intake.

3. you have to use a auto tranny unless you get a custom forged crank and bell housing to fit w/ a manual tranny, another $7000+ atleast.

4. You'll need a programmable ECU if you want to tune it to work good on a lighter car

5. they are rare!

Yeah big displacement sounds extremely tempting but is it worth it? To trade in for a WRX or turbo a EJ25 makes a lot more sense. It would be a great project for like a racing team though

Stupid Question: If looking for a newer better more powerfull engine upgrade, why not go "rape", as you put it, a new WRX for the parts. Wouldn't that be A. more powerful, B. lighter, C. a closer fit to the RS, D. able to use a manual tranny?

Am I being silly, or does this just make too much sense?

I don't think that the H6 has any advantage. It isn't the right choice.

I never thought or cared if it was the "right" choic., It was just a possibility. It would certainly be a unique and powerful car, but if it won't work, it won't work, no biggie. The thought of having a 6 cyl Impreza was just cool, so I asked about it. That's how we learn things. Back to the plan of a 2.2L with a turbo. Cheap and easy to find.

well if you can get over all of that .. could you handle an automatic transmission... iirc the H6 has NO fly wheel only a torque converter.. so a manual tranny won't work.. icky
