Why the dramatic price increase from the 6758?

Is there new tech on this one or is it just because its bigger?

You know what you have to do now

Some Indy engineers told me they've had a lot of failures due to the Aluminum Bearing housing.

I wonder if that will be an issue on a street car?

Its just a little bit bigger. 7064 starts off at $2k btw.

What makes me ~~excited~~ wet is the twin scroll housing.

Get a hew transmission before I do anything? lol

If my 3.308 keeps traction under control, then I am going to be seriously looking at the 7163 T4 TS w/ QSV, if Abe can make a manifold that keeps PS and AC.

I like the twin scroll with twin scroll manifold. QSV is for suckers.

Sure, but you won't be able to keep the hood :)

It is also possible that the 6758 may be the best choice for me. :giggle:

I want to see more applications use their smaller turbos...

I want a twin-scroll v-band

So when are you getting one soviet?

I want pictures of v band inlet on IWG housing.

I had a 7064 twinscroll on my 2.0L WRX. Frankly, too big for me. I realize I'm in the minority and not chasing dyno sheets.

I'm not ripping the 7163 at all. All of the EFR turbos are awesome. Just for this community, 6758 is about as big as I think we ought to go. Really, the 6258 is plenty. Our drivetrains can take it anyway.

If I was going to build another Subaru with a 2.5L, I'd be going 6258 all the way. I like a low torque setup. For the miata, I wish they made a slightly smaller option. Just my 2 cents. V-band in and out. That's what I was holding out for on my next Suby build.

The 6258 is "too small" for the 2.5. Its not going to make noticably better low end than the 6758.
