Which Engine?
 

I have been looking all over this freakin site and cannot find anything usefull on the engine types. Even though the 3rd gen rx7 is really unreliable i still want one. I will race a little but i want to make this a car that will last for a while. I was told by friends to do an engine swap. I don't wanna spend over 8g's. I just want to replace the current rotary with either a more reliable one (if anyone knows of one let me know) or even a 4 cylinder. Does anyone know of any 4 or 6 cyl engines that will fit it nicely that can handle some boost?. I don't need a powerhouse just something around 400bhp. Post if you can or at least post a link to something usefull?
Thanx
