So I've done a lot to my 05 1.8T and I'm excited to do even more, and take the next step by upgrading my turbo. I just bought this one: BILLET KO4-015xl K04-015XLB XS-POWER Upgraded K03 Turbo VW Passat Audi A4 1.8T, Volkswagen Turbos, XS Power Inc.
My car's engine is stock so I can't go too crazy with it, but I am beyond excited to upgrade from the baby k03. I've heard so many good things about this turbo, and my car is ready: front mount intercooler, Bosch 550cc injectors, stage 2 clutch + single mass lightweight flywheel, diverter valve, among a few other things. I'll be going from barely keeping up with newer econoboxes to full-on sleeper. I chose this turbo because I don't want lag until 5k rpm where I can't even have fun on the street. The size, and the fact that it bolts straight up convinced me. It's a huge upgrade from an eBay special without breaking the bank on a BT that I can't even use. I can't wait to get it buttoned up and update my thoughts on this little guy.

What are you doing for tuning?

Motozaperformance.com is my tuner. I'm currently on a stock turbo e85 tune from them, they're great.

Nice..
how many hp you expect?
I have xs power turbo but LB version . K04-015LB (46.5/56.5 compressor wheel).
I dont have time to install her.

It's supposedly capable of 295+ whp. I don't expect that much because I have a stock block, but I do have some decent supporting mods. I genuinely have no idea how much actual horsepower I'll have. 250+ wheel would be amazing, hopefully I can dyno it.

 

[PassatCRO]

I think that easily you could get 250 crank hp with that turbo.
I hope that you will get dyno.

If you run E85, it should easily make 250whp on a fwd. Just make sure there's not too much boost too early.

Sorry, a little off topic but how do those wheels ride. I hade 18” Audi wheels on mine and it rode
Like a tank so I put the stock 15” back on. Is there’s a trick you did? The 18” wheels also had a low profile.

Any update on this turbo ? How did tuning go with motoza ? Any issues holding boost or wastegate issues ?

 

[davewolsey]

did your wagon turn out well?? i’m about to install exact same turbo. similar mods or soon 2B similar as ur wagon, had K03s B4 & it was decent improvement over stock. looking for modest gain after flash up to 235hp so i don’t break any sh*t. very curious about ur results & opinion once complete. good luck-
