Well guys im sure we have all thought about it but i am going to ask:
What kind of horsepower and torque potential does this car have? Lets think of bolt ons only. lets also consider that reliability will be a factor.
What is the boost psi at now?
what is the engines compression ratio at now?
what kind of aftermarket support have been provided for other mazda vehicles?

Here's my thinking:
exhaust will pick up at least 5whp probably more because of the turbo on there.
Front Mount Intercooler will reduce heat soak and keep horsepower more consistent
Intake
The chip would vary depending on the boost bump.
underdrive pulleys 4-7whp
Maybe the HFM (high flow meter)

 

I've spoken to some of the Mazdaspeed guys and rumor has it of Intake/Exhaust pkg that yields 30 hp.

I've seen a 2.0L putting out 420 whp so just about anything is possible.

 

I will be getting a MS3 soon. wondering where you spoke or how you found mazdaspeed guys? also any help on the best place to find performance parts for mazda

 

I work for Ford in Michigan and used to work with the MS guys here in MI regularly when I worked on the Mazda6 program. The parts are still under development and aren't available to the general public yet. These parts would be available throught he dealership.

 

nice keep us updated please

 

If you actually pay to have the dealer install it you'd be at 293 hp with your warranty intact.

 

he knows of what he speaks

 

if horsepower potential is the question then getting it all to the ground should be the next

 

Well...That 420 hp 2.0L above was running low to mid-12 sec in the quarter, so it's possible.

 

One issues id like to know about is:
Did mazda redesign certain aspects of the speed3 in order to handle the hp, turbo and related pressures?

Sometimes automotive manufacturers slap a turbo on their family sedan to make is "sporty" this usally means busted transmissions if the car is abused, broken rear ends. What happens when you start to mod these bad boys? 293 hp in a family sedan would be even worse assuming that Mazda didnt strengthen things.

I wonder what a stock mazda speed 3 would do to a corvette in a straight line?
