Is there any cheaper turbo's that have the same spec's as the turbo's listed in the title? there's no tuning shops around tulsa, so i have to stick to the cobb base map, also on witch hunter they have some cheap injectors but their rated at 800+cc, would these work if the map calls for 565cc pinks? If not i hope they have some in 565cc, 150 bucks for a set of 4 injectors is a good deal including them paying a bill for ## stockers.
