tdo5-16g that can put up equal to or better numbers and is better all around (through the powerband). Keep in mind my mani's are external wastegated. Or even a internal wastegated just for information sake. Could you email me some charts or other good physical info? The only I have seen with my limited searching is the hks's........but reliability has been an issue for them. Just to throw it out there, my turbos are over ten years old with easily 60k on them and only one has had to have been rebuilt and only because of an accident that caused it to eat some metal chunks. It was even loaned out to a friend for some time as well for him to play with. I have seen repeated posts with people having to replace multiple turbos (BB mind you) from HKS and Garrett within months of having them. Mine have yet to die. I know they are old and outdated and blah blah, but I need a real good reason to blow a few grand on some new turbos......and trust me I've been looking for one.
