A clutch as well as upgrading the fuel system (oem lift pump)The difference between the Sr and Jr is about 130HP, that would be worth getting the Sr then it sounds likes, but what other mods would be required in order to run that?
Yep, it should have the in-tank pump now.I think I had the lift pump replaced recently under warranty. The engine died while driving and they replaced it. I think they replaced it with an electric pump, does that sound right? Sounds like this has been a common problem and they repaired it.
