Can't tell but from your pic it looks like you're in a regular 3?

Maybe tell everybody what you're working with so far to help get things rolling? Also, what's your end goal for the car, power/drivability?

You do not have enough mods to worry about blowing your engine. If you are that wprried about it...waste your money and build it.

If you have the stock turbo...i think its pretty much impossible to get enough power to actually blow it (unless of course u have a shitty tune...or try to run 30 psi :shock:).

I wouldnt be worried unless you put on a aftermarket turbo

I\'m surprised you dont have any type of WI setup on that car.

Meth saves lives. Get it asap.

Well, you are definitely smart for having the fuel pump internals if you are worried about blowing your engine. If you didn't have an upgraded fuel pump you would be more at risk. But since you do, you are better protected. You are fine dude, really.

I'm going to have to disagree with some of the guys here. A lot of the motors I hear about blowing are on stock turbos, running 20 psi and even have meth injection. Boom.

Fact is, the rods in this engine are weak. At a bare minimum, I would replace the rods. I haven't heard of anyone blowing a piston, or bending any valves, but I have heard many, many, many people throwing rods. Also, a lot of people blowing their motors as of late are using the AP v1.03 maps. Unless you live in Portland or can have your AP custom tuned by these guys: http://www.mazda3forums.com/index.php?topic=130069.0, you are kind of SOL when it comes to a custom tune for the AP.

I would say for your power levels, keep what you have but get, at a bare minimum, a GT2871, forged rods, and sell the AP for a CPE standback PnP. For now the AP is just not the tool to go with to get reliable power.

I say get the GT2871 because it will spool the slightest bit later than the stock turbo, but will give you a lot more top end without running out of efficiency like the stock turbo does at 20 psi. Seriously, if you want a reliable 350 to the wheels, stock turbo, or even a clipped stock turbo, is just not the way to do it.

Interesting. I've been on this forum for about a year and I have never heard of either of your claims making someone blow an engine.

I've never heard of someone blowing their engine on the stock turbo simply because they ran 20-21 psi. Frankly...I don't recall anyone blowing on stock turbo (i could be wrong). All the claims I've heard are people strapping upgraded turbos...and either getting to much power (350-400ish whp)...or getting boost creep into the mid-high 20s.

And I have NEVER heard of someone blowing their engine because of ANY of Cobb's AP tunes. I'm sure there would have been a huge discussion on it if this really happend.
