s4 13bt
 

anyone know where i can find a low milage s4 13bt for a good price, cuz everyehere i look and yes that includes searching google, are only s5 motors, and also is it true that an s4 can handle more boost than an s5 because the rotors are heavyer?

The S4 can take more detonation than the S5 because the rotors are cast iron. But the seals are going to go long before the rotors become the limiting factor.

I have S4 TII motors here if your intrested, but there all built and there not all that cheap.

i can get the whole swap cus thats the way we sell them but they go for 1900 and there jdm motors s4

You said that you can only find S5 engines, when i did a search i only found S4's!
