Hi guys I have a snort stage 2 turbo kit but i'm looking at doing a turbo upgrade... I have a AU motor with double valve springs in a EF with 80lb injectors sard reg 044 pump and a Haltech e6x full 3" exhaust... I would like boost to come on later right now it starts to spool at 2500 and hits full boost by 3000. i would like it to start to spool 3000/3500 and hit full boost by 4000... so if anyone can give some thoughts on a good turbo to suit.. I found this but not sure if it would work
