Although lightweight the F-5 and F-104 are not really comparible fighters - which is why I believe it was mentioned by Lexx above.
The F-104 like the F-4 relies on energy only and its best manoeuvrability comes at high speed - (say 450+kts) for example
The F-5A had comparible horizontal turn performance to the MiG-17 in the low speed (say under 400kts) - but I dont believe it was really an energy fighter - especially if compared to the F-104
(theres a great article by Andy Bush on F-104Gs Vs F-5Es from when he was at Top Gun)
The F-5A had no radar- the F-5E was larger, faster, had a radar and was a true A-A fighter - pretty sure neither could get near the F-104/F-4/F-15/F-16 regarding energy and speed performance (thats why they tried to do an F-5G/F-20).
