I currently have fitted a GARRETT GTX3076R to my sr20, its brand new and I am ready for mapping... but my mapper has told me its a shit turbo and I should of gone with a GTX3071R.. he says its a much better turbo, spools faster etc..
whats peoples thoughts?
If I need to change it I will but its annoying as the 3076R is brand new and not even been run yet
