Can anyone modify 05 turbo?

[J.Davy]

Just curious if anyone can put a bigger exhaust housing on the new turbos to help get rid of some back pressure?

Call Piers.

They might be able to install a larger wheel and hog out the exhaust housing.

By the time you do that you coulda paid for more than half of a S300, and be well ahead of anything you'll ever get out of a modded stocker.



Piers doesn't generally mod the exhaust side, mostly the compressor.

Theres nothing to mod on the comp side Vaughnnn, the 05's already have a 62mm comp wheel.

The old 03 and 04 turbos had the little 56 IIRC.



Or you could just buy a b104 and be done with it.

That was my logic after reading that it already had a 62mm comp wheel,if you could get it up to a 12 or 14 size on the exhaust you would probably have a nice little turbo as a quick fix. I am waiting for twins therefore I don't want to buy a expensive single that won't be compatible later on.
