i have a 2006 mazda 6 2.3L engine and want to put a 3.0L v6 in what has to be done?

 

As a general rule, operations such as this typically cost considerably more than it would to simply sell the car with the small engine and buy an otherwise identical car with the big engine.

 

Sell your car & just buy a V6 model.

^^^ what they said.

 

This is kinda like the old adage from the BMW community...

Q: How do I make my BMW faster?

A: Sell your car and buy a faster BMW.

 

I'll disagree with that to an extent. There are things you can do to make a given car faster, but for something as specific as this, it would be more cost effective to sell the 6i and buy a 6s. Now to make the 6s handle better, or be faster around the turns, it's cheaper to upgrade the suspension a bit on the 6s than it is to buy a speed6.

 

ok sounds like thats the way to go thanks

 

Unless you are in fact a glutton for punishment, do the above.
