I want to put the K04-24 (225 TT turbo) on my 180 TT. I am going to but the ATP Turbo transverse exhaust manifold which can bolt to any K03 and K04. So I know the K04-24 will bolt to the new manifold and the new manifold will bolt to the engine. But What Im not sure about is will the K04-24 bolt to my 2.5 tectonic downpipe I have on now. The downpipe is a 4 bolt and Im not sure if the K04-24 is a 4 bolt or not. Anyone know?

Also does the size of the openings on turbo housing get bigger as the turbo gets bigger? If so would that mean that my downpipe wont fit?

Software isnt an issue as I already have GIAC and I know they do K04s too.

Thanks all

 

you said they do k04's but i think you still need to reupload for that turbo. they probably wont charge you again for it though. it's a different map file.

 

So no one can ive me any help on this? I just need to know if the 225 TT K04 has a 3 bolt or 4 bolt connection at the downpipe. And if anyone know if the 225 K04 will give me 30 or 40 more HP than the K03 sport turbo.

 

Its a 3 bolt, can't help w/ hp numbers
