The ultra performance OS91VRDF is nickel plated.
Amir,
Although the Tower web site does state this sleeve is ABN, Bill Baxter (BAX) got on the horn here, stating the OS.91VRDF sleeves are true chromium ABC and that the Tower tech dept. often makes these boo-boos in their product descriptions...

I have this engine and I am pretty sure it is ABN as when I look throught the exhaust port the liner looks like a it would be a steel liner. I can not see the brass on the outside as I would do on my ABC engines.
Sorry you other guys as I dont want to change the subject of this thread but my point here is that the cheaper price and longevity is not the most important factor when choosing a model engine if you dont get satisfied by the way it runs and behaves.
