Okay so I am getting my sister's 2007 Mazda 6, 4 cylinder 2.3 liter engine and it has like 150 hp which is pretty sad. I have literally have no idea how this works so is it possible to put a a v6 3.5 l engine from a infiniti g35 or nissan 350z in it? if so could i fit a v8 4l ?

thanks,
i know im a noob please refrain from getting mad if i get something wrong

Anything is possible, but you also have to consider other things, like weight distribution.

I think you'd be better off going turbo on that motor rather than swapping in something new. Even with that you're talking $3-4K

i can handle 3-4k but how much more hp would i get with that?

Where to begin;
Yes, as vaguely stated 100s of times before, anything is possible. Like my friend pointed out, it comes down to logic more than anything. Even if you have the money, it's not always logical. For the swap concern,not logical.

With turbo,you could double the wheel horsepower, logically. The main concern after that is not just what to do, but how to safely do it. Boost brings up concerns of internal failure. The last thing that you want to do is boost the car for 3-4k and tear up the motor a week later. So, logically, you want to keep the boost down below 10 psi and that would put you at a little less than double with the correct supporting mods. I am on the mobile right now, so I will have to get back with you shortly on a resource for a turbo kit.

Engine swap? My question there is; How much do you like wiring? Cause you have more issues than just getting the engine to fit in the bay, mate up to a tranny and other driveline components, you also have to get the guages and such to talk to the new engine, which can be a real pain in cars today.

Honestly, I'd recomend going turbo for you the HiBoost claims to get you to 225hp with an otherwise stock setup, and 250 with a 2.5" catback and 8psi of boost. If you are after more power than that, you will likely have to build the engine and that's gonna get pricey real fast. The HiBoost kit can be found here. I say, get the the kit and enjoy the added power. You are not likely to build this car into an 800hp monster like a supra or some such, but 225-250 hp combined with a properly set up suspension will give you a car that is an absolute hoot to drive and will carve corners very nicely.

thanks guys, turbo seems like the way to go, would this be a good exhaust i heard its sound on a couple you tube videos and its sick.http://www.hottexhaust.com/detail.asp?PRODUCT_ID=15803 who likes this body kit? Do you think i could put lights where the circle holes are at the bottom?

thanks,
Reed

That is the system I just put on my car, and I absolutely love it. I need to have a shop do some tweaking to it's alignment though (I'm a little OCD about this type of thing), but it looks and sounds great!

As far as body kits for the 6 go, that one isn't bad looking. I don't know anything about that particular kit though so I cannot comment on fitment or anything like that.

By rule of thumb, body kits don't fit well. There is always tweaking, drilling, and adjusting going on for the installation.

True, but some are worse than others. Which is what I meant.
