Hi Guys I've run a search but could not find what I was after, apologize if it has been asked. I am looking at a couple of upgrades Borg Warner EFR 6258 twin scroll turbo upgrade (rs 265), what I need is the factory manifold specs to see if the flange etc line up or I need more fabricating.....also what is everyone's thoughts on best upgrade. 2nd is Intercooler, thoughts recommendations. I am looking at a Plazmaman 600x300 76MM Any suggestions, thoughts let me know. The car has been mapped already.
