I have a 2001 audi tt 225 awd. Im wanting to upgrade the turbo with a 16g or big 16g from an evo. will i need any extra or additional parts to complete the swap of the two turbos? If so can you list what i will need for the project.

ps. i wanted to go with the big 16g because its a little step up from stock but im not trying to make serious power. I want the most i can get on my stock engine with my chip, and minor bolt ons.

 

we could do good w/a chip,intercooler,w/m inj, and etc. a bigger turbo even a t3/t4 produces a lot of power

 

if i chose the 16g or the t3/t4 will it fit directly or would i need other parts for it to fit correctly?

 

no u would have to change the exhaust manifoldsetup and intercooler etc

 

depending on power range

 

that sucks, is there any other turbos out there that doesn't require new mani, etc....?

 

Quite frankly nobody uses Mitsubishi turbos on 1.8T's. GReddy makes a kit, but it's only for FWD MkIV VW's (or FWD TT's) it uses a TD03-19H if I remember. And impressions of the kit weren't very good last I heard.

Anyway, since you have a 225 you already have the bigger K04 meaning you have no place to go other than bolt ons or a big turbo setup. So unless you wanna stick with bolt on gains, you'll need a new mani etc.

 

ok, i had found this out today. take a look and let me know if its a waste of money. you said i already had this ko4 right?
so would it be worth it?

That is smaller than the ko4-20/22/23 turbos used in the 225. As for the mitsu 16g, there isnt a manifold or dp made to use that setup. Its easier and more powerful to go with a standerd t3, t3t4, or gt turbo setup from garrett. You can get a excatly the power level you want and save yourself tons of work.

BTW, TT stands for Tourist Trophy...... NOT TWIN TURBO!!! You only have ONE turbo

 

does tt really stand for tourist trophy?
