i am now going to start buying bits for my gt28 project for my astra gsi
i am currently running regal stage 3.5.
i need a bit of help on what i need. I want to spend minimal as poss but want to hit at least 350bhp on standard internals.
once i have done the internals i would like to see over 400bhp.
but for now i am going to be running standard internals.
if people could be kind enough to help me out with a list on what i need would appreiate it!
