It looks like here from the figures that any subaru under a 14 second quarter mile time is a turbo and all of those over are a non turbo. So I can head out in my pony car and beat a non turbo subaru if Ichose and risk the legal fees. Or, I can assume that when I see a non turbo subaru being beaten on by a kid who borrowed it from the parents and not getting out of it's own way that they are not that fast.

An all wheel drive Impreza weighs about 3,400 lbs. If you put the same engine in a 2,000 pound Type 1 it will run circles around your Fox Mustang. All of that aside you guys are 2 different kinds of enthusiasts, there is no right answer. But I'll tell you this, the Subaru conversion is not a fad. More are being built all the time. Also remember Subaru advertises there engines with full smog controls. If you pull all that shit off of one and get a pro tune you'll have an easy 200 hp. It takes one hell of a ACVW to match that and it certainly won't go 150K with nothing more than oil changes.

One mans opinion

I was thinking of buying a subaru as a daily driver and researching a swap for a type 1 after finding out that my type IV case was not usable. After I read some guides on subaru engine rebuilding I changed my mind. Boxer engines biggest gain are that they are light and short from the flywheel to the crank pulley. An aluminum split engine case does not hold up well to abuse and in the subaru's case the best option is with a new engine replacement. Along with the adapter plate ,what to do for a transaxle ,the huge amount of wiring and boogering up the car with a radiator it is not practical in my own opinion. If the case held shape it would be a different story.

I was/am looking into a rx8 swap but every one wants top dollar for a engine that has to be a replaced warranty version because the originals were garbage and they themselves are swapped out because of negative aspects. This is looking to be non practical as well. Some my say stupid.

Dude, have you just ignored everything I posted? A non-turbo Forester (the car YOU picked remember) puts out 165hp AT THE WHEELS and runs 16.8 with an auto trans. A 5.0 Fox body puts out 210hp ALSO AT THE WHEELS and runs 16 flat with an auto. OF COURSE your 5.0 will beat a non-turbo Subaru, it's got FIFTY MORE HORSEPOWER. All cars sold since the early 70's have been rated in WHEEL HORSEPOWER. That includes SHITTY FORDS.

There, I put the important parts in caps so maybe you won't be able to gloss over it again. I really don't know why I'm bothering the though. I think I'm done here.

I've been reading dyno charts and looking at random info on the newer rx8 engines. I knew they consumed oil and fuel-some of the other things I've been reading are pretty surprising. Still, with your max hp coming in around 8500 RPM and max torque at 5500??? At below 3000 RPM the torque is weak like a 1600 ACVW. I don't see it as an improvement over the subie at all. No aircooled trans can handle this fast revving engine in a daily driver. You would need the matching trans as well. After all that hackage, I'd be kicking myself for not doing a small block v8 instead. If rotary swaps are so good, they be popular still. In the 80's, it seemed more popular than the Subaru. But the 80's Suburu engine was not sporty or a real upgrade. Now, the Subaru is a powerhouse without the quirkyness of the rotary.

There are a lot of things that can fail in a VW trans. Besides all the power it has to handle, it's obvious when you take one apart it's not meant to spin at 8500. Most of the common racing mods for a tranny are for better shifts and power handling. Even then, drag race cars are not doing their 8,000 RPM every day. Just look at the play in the input shaft. The ancient designed hubs,gears, bearings, type of gear oil, etc. The more you look, the more you notice it's a terrible match for highway miles with VW trans. It's a low geared miniature heavy duty truck gearbox. I don't think any of the common mods will save trans death while holding 5-6000 RPM long drives. I know it seems like a cool swap from a size perspective, but I think it's a bad idea.
