13B-REW to LS1 Perspective

[David Jerome]

Although the IC and Radiator arent teh best I dont see them as real problems.

Mazda waiting for 108c for the fans to hit full speed, the AST, and the FPD are the 3 things I think that gave the FD such a bad name. Everyone always makes comments about how unreliable the rotary is, however, when I drive an fd engine failure is the last thing I am worried about. It is all the accessories on the engine that lead to engine failure that scares me. You would be blown away by how many fds I buy and customer fds that show up with leaking FPDs. Its shocking.

I think it all comes down to preference. If you want a unique engine that is a thrill to drive, revs high, and makes the inner child scream, the 13B is your engine. If you want an engine that makes little children cry because their big wheels don't match up and that puts down phenomenal power, get an LS#.

Agreed. One of the main problems with rotaries is all the shit that's strapped to them. I've never had a problem with my engine (granted it's an N/A FC), but rather all the 8 jillion things needed on the engine.

I'm going to have to disagree with that part of your post, and only that part since the rest is pretty much spot on.

Regardless of what people may try to argue, there's no replacement for displacement (at least Wankel rotary vs. piston). People argue that you can turbo a 13B and have it make just as much HP as an LS#. Sure... you can... you can also take the same turbo (or something comparable) and put it on the LS# and blow the 13B away.
