Audi B6 A4...LSx swap...Twin Turbo

[justwu123]

I've had this B6 for about 2 years now...it started out as a car I was just going to fix up and do a quick flip. It needed a fender bumper and some paint. Got all that done and I had a very nice and stock Audi A4 3.0 fwd automatic.


A week later during a test drive the trans blew...had no idea really how or why it happened but it did. So I pulled the motor and trans and sold it on eBay.



I then had no idea what I was going to do with this perfect b6 shell...Possibly a b5 2.7tt swap...maybe a s4 v8 swap...finally I decided to go way over the top on a lsx motor 5 speed trans and rwd! $300 later I got a nice place to start: a lm7 5.3L from a 03 silverado. Heres how it looked after tearing apart most of it



More to come later!

You are doing something Audi should have done ages ago. RWD-ing a V8 A4!

This is great.

Trans problems, might as well go twin turbo lsx. I like this guy.

haha thanks

Whoa what the hell the build progress just went from 0 to 100mph . I love this, unorthodox, ridiculously powerful, and a serious departure from audi's quattro obsession.
As for wheel color, definitely a fan. Contrasts the body color nicely without screaming for attention. In for more!

[SLC450]

Sweet.

[FunfGang]

Oh my, most definitely in for more.
