Hey everyone
So I currently have a 2005 golf gti and I have no plans of being rid of this car anytime so I’m looking at improving what’s there and want to put in the bhz lump in mine to future proof when I go for more power I’ve read a couple forums but maybe I’m abit clueless still but I havent seen a guide (or I’m blind) on what exactly I need other than the engine I’ve seen some say you need clocks and ecu and others say no you don’t so I’m just looking for a straight forward what I need to do this if it’s just engine and then mapping great I’ll go to rtech anyway since they were great with my stage 2+ but if I need the ecu and all I’ll still be going to them but I just know more of what to expect
Thanks in advance
