Need help identifying these two cars

[Scottmh]

I bought two r/c cars for $50. They are partially disassembled and I am hoping you guys can identify them for me. The guy i bought them from didn't know because he bought them in the same condition. Here are some pictures.
Car 1:

Car 2:

They both appear to be early model HPI RS4's

Kinda what I was thinking also but which of the two is the newer one?

If I'm not mistaken the first car is a super nitro rs4. The secone is a regular rs4. Both cars are over 10 years old and the parts are very hard/impossible to find. You may want to re sell them as parts cars because like myself, I have an hpi nitro rs42. Hope this helps, Steve.

Shoot I was hoping to fix them up.

If you want to sell them as parts cars, let me know and when I get the cash I'll take them off of your hands.

Hey Scott, where in LA are you?

 

[Scottmh]

I wonder what it would take to convert one too electric

 

[Scottmh]

ok i think I've found out that the second car is a duratrax street force gp. sound right?

The first one is an HPI RS4 2, most of the parts can still be found on ebay. The second I am not sure about.
