does anyone know how big the turbo is on the 1.8T?
If you guys can tell me that would be great. I wana know if its a prety good size for being a stock.

 

All I can tell you is it's a K03. It can handle about 1bar (14.7psi) of boost.

 

heres a K03 and T3/T4
guess which one is the K03
u can use the pennies to compare the size of the turbo
its not that big

 

The size of your fist. Literally.
I don't even know what you mean. It's small enough that it can hit full boost by 3K RPMS, and small enough that it can't flow enough air to make horsepower past 5700 RPMS or so. It can handle a little more than a bar of boost, (14.5 psi; 14.7 is atmospheric pressure, which is slightly different for some reason) but by 19 or 20 psi it's out of its efficiency range. It's not big by any measure. That doesn't mean it sucks, although you won't see more than 220 hp out of it ever, but it's tiny.

here's a link to a dyno'd turbo swap

is it possible to get 275hp at the wheels with that turbo?
or at least the TQ up to 300+

 

cool thanks for helping me out.

 

About the size of a donut really. Its a good turbo, its does what its design to do. The ko3/ko4 are torque turbos. My old ko4 i think made as much if not more torque then stage 3.

 

mabey a dumb question but what do u guys mean when u say a "1 bar or 3 bar turbo"??? whats a "bar" ?

 

1bar=14.5psi i think

 

Yeah, bar is simply just a another measure of boost. Chips range from .8bar to about 1.8bar
