i am the biggest fan of mazda rx8 because of its sporty look. but i have done a bit research on it and found that it has a engine problem very frequent so i wanted to ask wheter to do a. engine swap or by care it doesnt causes problem
secondly if swap then by which 13b rew, 3sgte, toyota supra engine and does engine swap causes problems which lead.to accidents
i want the car for enjoyment like full rpm acceleration
and i live in pakistan

 

None of those engine swaps are easy or cheap (or even doable, there is no space under the hood for an inline6). It's far easier to just replace the engine if something happens. That's assuming your country has places that rebuild rotaries and access to fresh parts.

If you have the money and time, Chevy V8s are at least a well documented option.

 

There was one guy doing a 2JZ swap, but I haven't seen much of anything about it. Any engine swap performed incorrectly can cause issues. It all depends on how much money and time you're willing to spend working on something. If you have all the time in the world and at LEAST $20k USD to throw at things, you can do a V8 swap.
