I live in the US, and with the H6 engine I wouldn't know if its best, to have it modified in a wagon body form. But I notice that the Outback also comes in a sedan form as well with the H6 engine the 02 model would be the EZ30 engine but not the EZ30R. The 6 speed swap sounds promising, since parts are possible to be found at Ebay.

The choice is yours in accordance to your circumstances and discretion. But, my advice still remains that if you make the initial investment in a car with all of the above as stock you stand to make a substantial financial saving in the long run. Best of luck. Lemme know how you go

That's an awesome car. I have a legacy in possession. But I was wondering if its best to get an engine swap in the legacy. Or get a stock 02 H6 outback, change the ecu to an aftermarket one (because of the security limitations), and get a manual transmission afterwards with a transmission ECU. Comments would be appreciated

I'm assuming thats a rhetorical question... But, just in case it isn't; buying a vehicle with all of the above as stock features would be far far cheaper than sourcing the parts in question and swapping them into another car. I recommend a Legacy Spec B with the H6 engine mated to the bomb proof 6speed manual STI transmission all stock from the factory - they do exist! The Outback is a large wallowy car not built to handle this kind of power (350+Kw at the wheels in this project).

Hey, good to hear from you again, sounds like things are going great with your Legacy, This is a excellent project with excellent results.

300kw at the wheels at 10psi is very nice!

Keep up the good work and it would be cool to see more vids of the car in action!

In the rain I get all four wheels spinning at 2800rpm. I have to really feather the throttle to get any sort of decent start off the line in the wet. In the dry though, its unbeatable. We are now prodcing over 300Kw ATW with stock internals and 10Psi. We are currently working on engineering the internals of a 3.6L engine with the aim to use upto 21Psi.

Hey there,I had to laugh with your comment about the stereos,because i rarely use them on either of my cars as well!

The four wheel drive system on the Legacy does a good job of keeping wheelspin in check, it usually just grips and goes, although sometimes i hit boost in first and there is a bit of wheelspin but not much.

It should be more of a factor with the power levels you want to achieve.

How is everything coming along by the way?

I know what you mean about the M3 engine only too well, I drove one for a little while, I felt like a hooligan al day long. But that Msport straight six set the benchmark for other sports straight 6s and V6s. Besides couldn't justify driving below 4000rpm given the way it sounds past that - hardly ever used the stereo - just as I have no idea what people are talking about when they ask me what the McIntosh sound system sounds like in my STI. Do you loose any traction when you wind your turbo up?
