They are used , not rebuilt to my knowledge . Removed from a fd due to single turbo conversion by the previous owner .
you can see the "knight sports" logo on the compressor housing...
Bought it from a guy who works at turbonetics,
they made a "centerpiece" of it as he said , He didn't know if they were rebuild or not .
I guess they cleaned the "turbos"... no clue.
Should I be worried about the bended actuator ?
it seems the compressor housing is missing the "dual nipples ", can I just reuse the one from my old twins?
Assuming you get them installed are you going to run them sequentially or non-sequential?
At say 1.0 bar (14.5 PSI), assuming the same car and modifications, what is the horsepower gain of the RF420s compared to stock twins running 1.0 bar (14.5 PSI)?
Is there a power gain across the entire RPM range? Are the RF420s laggier and by how much? Do the RF420s continue to make power beyond 6,000 RPM unlike the stock twins?

The stock oem nipple piece coming from the primary compressor housing is a press fit - not threaded. Looks like Knightsport made their own piece there.
The "bend", are you referring to the top of the wastegate actuator, being pushed down slightly, hard to tell from the pic?? It might preload the spring a bit more...and keep the wastegate closed a tiny bit longer...I wouldn't worry, as long as the actuator is serviceable.

I thought so , wonder were I could find the right part now...

Here is a better picture,
Since it is bended , I was wondering If I could just swap it with the one from my old twins.
