well I have 2003 1.8t 5mt, im looking at a set up to run a holset hx30, with maybe around 550cc injectors and a revo stage 3 tune for the gt2871r as they seem to be in close resemblance. does any one have any thoughts on this setup? I see not many people have run an hx30 on this cars, but im trying to keep the car as a cheap dd build. Ive also thought about running an hx35 as my buddy has one laying around for cheap, but not 100% sure and just looking for input.
