going to buy a garret t28 Ball bearing turbo, dump pipe to suit, custom made mainifold, full 3inch exhurst system, chrome twin dumper, stainless steal piping- with high quality silicone joints, Front mount inter cooler 400x300x74, and water +oil lines.
are these components the best choices for an astra g 1.8?
what mods do i need to do?
can i run on the standard computer or should i dyno it?
and what power increase should i be looking at?
thanks in advance
