what is the easiest turbo to swap onto an 05 sti? are there any that mount to stock up/dp and dont require tgv deletes to run?
Any stock mount turbo, with a 2.4 inch inlet will fit. These incluse 18g, 20g, green/sz49/gt49, red/sz55/gt52, the blouche dominator series.
^^ Yes, sorry the red is only a 3" inlet. Any of the others I listed will work fine. You HAVE to make sure it's a 2.4" inlet, then there will be no TGV problems.
ok..one more ???..do all of those turbo's require any other mods??(walbro 255,injectors?)..i have a stage 2 sti but have a perrin 2.4" inlet and i already have a walbro fuel pump...anything else needed,i would really like a turbo that doesnt require many more parts because i am on a tight budget
I would say almost all of them would require at least a fuel pump and tune at the very least. I would get the above mentioned plus bigger injetors if going with 20G or bigger.
