Rotrex powered EM2 BUILD, the final upgrades!

[BoostedK20]

More Canadian sadness! Plowed in and frozen solid, sometimes I realize I'm not responsible enough to have a baby..... Lol. Luckily the temps went up to +8 Celsius a few days this week and I shovelled it out and put it in the garage.

And on the more fun side for winter to help me get through the depression of storing my baby, I have this little Manual Quattro mistress. These are 19x9 with 235/35/19 winter tires. Because you gotta look boss in every season! I never looked forward to huge snow storms until I bought this.....

B6 S4 is one V8 that I love. A good friend of mine is an Audi Whore (on his 9th Audi in 4 years) and of all of them, the b6 was my favorite. A good friend of mine owns Elite Motorsports and has a B5 S4 TT and an 04 Gallardo. Audi has always made beautiful setups!

Two more for fun, because everybody loves pictures.

Glad to see you had fun, I like your taste!

The fact you got a blower for 1k amazes me. I Paid $2700 for mine and I got a discount on that even.

The -81 still makes great power. If they are that cheap I'd just buy another blower and then worry about fixing the other one and perhaps sell after its been rebuilt. I don't recommend rebuild yourself. I tore my old 81 apart and it was not pretty. There's things that need done that I didn't know about till after it was too late. Thankfully it was a trashed blower anyways.

Someone's mad! Seriously, it's a great price.

Wow this is a great build, sad I didn't see it till now.

Great build right? Gotta love the rotrex builds.

Thanks!
Pete I agree 1500 isn't a bad deal on a new blower, just sucks its not the -91 I was hoping to upgrade to, knowing it was the most power I could make.

As far as the rebuild, look up MrJackHeath on Flickr, he has albums on albums of his rotrex rebuilds and modifications changing compressor wheels to flow a lot more air than they do from the box. He shows each step for disassembly and tips on reassembly. He was the one who convinced me to try since otherwise it's become $1000 paper weight. It hurts knowing it still works, just a matter of time until it implodes if I don't try rebuilding it lol.

I know the -81 was flowing 20psi out of the compressor outlet when I metered it, so assuming 2psi lose to the manifold means I sure should still be happy with 18psi on a stock k20a2 block. Assuming wit meth injection I should have no problem hitting 450whp with my 88mm blower pulley, a2 crank pulley, and 8000 rpm redline.

Sounds fun! 18psi is a good amount on a stock block. Are you running headstuds? [MENTION=83]vdubkilla[/MENTION] has a great method for headstud swapping! And [MENTION=56]PetefromtheStreets[/MENTION] should definitely look up MrJackHeath on Flickr. It would interest him!
