Mazda Speed3

True. I had the Mazdaspeed CAI installed on mine when I had the car. It made a huge difference. A turbo inlet pipe should be the next thing you swap out. Get a Cobb AP too.

There was a huge debate about the turbo inlet pipe for a while... but none of them have shown any kind of power increase.

have you seen the stock inlet pipe? the turbulence caused by the folds and bends are apparent.

I'm thinkin about pulling trigger if I can fInd an 11.

Replacing the inlet pipe of the speed3 is a waste of time / money. The gains come from the intake so don't waste your money on replacing the stock inlet pipe as it works fine.

This! I have an 11 MS3 and I put the K&N Typhoon intake, I went with that intake because it has the block off plates to help keep "some" of the hot engine air out of the intake VS a lot of the intakes which sit inside the engine bay hence, drawing hot air into the intake.

The inlet pipe will give you a better sound and that is it, plenty have dynoed and not seen any gains.

Do you guys think that the Mazda speed 3 would be an upgrade for my civic?

The current one is definitely quick and handles well. I'd get one too if I needed a all-in-one fun utility hatch.

Honestly... not really. It's a step up performance wise but it's really the same "type" of car.

True. I'm just looking for a step up in performance. I don't want to downgrade

The Mazda Speed3 is defiantly a step up from a Civic SI granted the current generation model looks like a bag of smashed ******** IMO. The 1st Generation MS3 looks much better, is actually a tad quicker because of a more aggressive tune and it's 120lbs lighter. Otherwise performance is negligible but the current model has a smoother ride on rough surfaces.

Regardless, both are fun to drive, quick, reliable and economical. People often way over-estimate the so called issue with "torque steer" so don't let that bother you unless you don't know how to drive with both hands on the wheel between shifts for some odd reason and or understand this concept called throttle modulation. Just because the power is there it doesn't mean it must be used 100% of time.
