Our new Twin kit

[RETed]

No, I do not SEE the wastegates in your pic.
Sure, you're welcome to use EXTERNAL wastegates on your turbos.
GT28's all come with internal wastegates?
External wastegates just add to complexity, which in turns adds costs to your kits.
If you're trying to keep costs down, adding external wastegates doesn't make any sense.
If you're trying to make a no-cost-limit kit, then add the complexity with external wastegates.

"GT28R" is a FAMILY of Garrett turbos.
The "GT28RS" is just one model under the "GT28R" family.
Why don't you tell us what exact GT28R model did you use instead of getting your panties in a bunch?
