Yes, the RV275's are 40hp over stock. I'm not completely sure what the "RV" means but I was also to understand that those injectors were equipped in RV engines, thus the name. Strangely though Bosch's marine version are simply "Bosch Marine" injectors.
The Marine versions come in a variety of HP ranges too, and I want to say 300hp is the starting point.
And yes, as long as what you get is "genuine" Bosch RV275's, they all should be the same stock brand new injectors. I want to say that CPP has them for a really good price. So it shouldn't matter who you get them from as long as they are the real deal.....and a good deal.
The reason you hear everyone talk about RV275's so much is because they supposedly a really nice reliable drivable improvement injector over stock. You can still easily tow heavy and they should give you a nice little gain in MPG. They're essentially a stock injector so they likely wont result in any negative effects. A really good injector in combination with a mild timing/fueling box too.
I say all this only from what I've read over the years and the questions I've asked because I dont yet have them either. I plan on getting some in the near future since I wouldnt mind the mild increase in HP and the potential mild increase in fuel mileage as well. But I also understand that the stock clutch is only good for so much HP and I really dont care to install 275's with my EZ and fry the clutch while towing the family trailer. So I'll wait until I can get a clutch too.
