What you guys think?
I know that the RB25 t28 has the ceramic wheels that don't like boost

Rather buy a Garret GT 30/35 bb turbo if the money allows it,You will want more power sooner then later
Ask RB25SX if it will work out,Im not sure what benifits there are.

money not going to be there for a turbo soon.
the gti-r t28 has a 0.86 exhaust side and flows close to a gt28r

I think by the time you've realised how much time and money you've spent on the conversion, a GT30 turbo will just be something you need rather than want

btw, I asked for the turbo first, so i voted NO

Howdy...
can you explain why please?
The turbo is too small for the application the RB25 comes with a T3 turbo stock
PFB do you have the flow map for the GTi-R turbo?

If you're looking for a cheap turbo rather look into a correctly sized t3/t4 combo job. Should be a hoot on an rb25. Phone up a couple of turbo shops and ask questions. Ask if they can email you flow charts for their recommendations.
Should be a fun albeit expensive project.

I think the question should of been, "Is GTi-R turbo and upgrade over the stock RB25 turbo".
