In Topic: The 800 dollar Mazdaspeed 3 project

27 March 2020 - 06:29 AM

Long time since I made an update to this but I have done quite a few things.

Turns out it only came with a 3" TurboXS downpipe and a stock exhaust that had it's resonators cut out. Basically a straight pipe. I didnt notice it at first because I never really got under the car to look. Needless to say it was insanely loud. Replaced it with a TurboXS 3" system with race pipe. No longer loud and has a nice sound to it.

Replaced the pivot shaft housing/seal for the shift linkage. It is a common problem on that style transmission. I was losing quite a bit of fluid from it and making a mess.

Installed a CX racing front mount intercooler kit. My BAT (Boost Air Temperature) was getting pretty high at idle and heat soaking badly. Now my temps are stable and hover around the 105-100 degree range and drop quickly once moving.

Replaced the BAT sensor with a higher range sensor. The BAT doubles as a MAP/IAT sensor mounted to the intake manifold. Turns out the stock one only reads to about 22 psi. Once I replaced it and calibrated the tune for the sensor the car was able to run 24 psi without issue.

After doing research for the high pressure fuel pump upgrade I'm 99 percent certain that I already have mine upgraded. The stock HPFP only goes to about 1600-1700 Psi peak pressure. I'm seeing pressures around 1900-2200 on my AP. However my next purchase will be the HPFP internals. My co worker bought a 2010 MS3 so I figure if I already have mine upgraded, I will just give him the used parts for his.

The car came with a horrible single DIN unit that someone hacked up into the harness. Bought an android style unit that fits perfectly into the location and looks factory. It has GPS, hands free calling etc.

Installed 4 new Continental tires. Went from 215/50ZR18 to 235/40ZR18. The tires were all mismatched and one of them had a slow leak. Got all 4 for 600 total so not too bad.

The LF hub bearing had been failing from the start of this project. It groaned so incredibly bad it shook the whole interior once the car hit 60mph. Got that replaced.

Other than that I have been enjoying the car. It's a decent ride and I am happy with the progress.

You'll want to search for a Mighty Max non AC vent.

Not sure what this means Cary.  What bolts directly to the head?  And it has no exhaust manifold?  Please unconfuse me. :wacko:

The J series is the engine code for Honda's V6. In regards to not having an exhaust manifold, the manifold is internal to the head. Meaning all the exhaust ports on the head come to one collector. Manufacturer's have been doing this to save money on parts and to fit larger engines in smaller engine bays. The catalytic converter bolts to the cylinder head in these applications instead of having an exhaust manifold to bolt to.

As for finding an ECU to run a Chevy V6, you can find a complete V6 swap from a Cadillac CTS or Camaro. You would use the Engine, Trans, Harness, and ECU. There are a few things needed to be done to bypass GMs theft system or you could incorporate that into your car if you get all the right modules. Tuning would be done via HPTuners.

Direct injection isnt a bad thing. You only have to run one fuel feed line to the high pressure fuel pump located on the back of the cylinder head. There is no return line.

One last thing to take into account going V6 is how easy is it going to be to work on? If thermostats, water necks, sensors, etc are on the back of the engine then how will you easily change things? If the motor is so tight in the engine bay you have to pull the motor to do anything then is it worth it? For example on Twin Turbo 300Zxs the engine was so crammed into the car you had to pretty much pull it to do anything. Same with my friends 3000GT VR4.

FWIW I suggest sticking to 4 cylinders, Inline 6 engines or even LS or Hemi swaps. Plenty have been done here and the documentation is sound. If you do decide to go GM V6, I am a tech for GM and have access to a ton of manuals, connector/wiring diagrams, bulletins etc. I can also get OE parts for %10 percent over cost though with adding shipping I'm not sure would be cheaper than getting it directly from your area.

In Topic: 3" exhaust

11 March 2020 - 05:20 AM

I ran a 3" exhaust on mine lowered and it did not hit unless it was an extreme curb or bump. Even then it was tucked up pretty well. I did a dyno before and after between my 2.5 and 3 inch exhausts. There was a noticeable difference between the two.

My favorite things growing up were videogames and Teenage Mutant Ninja Turtles. I got into collecting them again about 4 years ago. My TMNT collection is fairly small, with about 20 figures. But my videogame collection is pretty big, over 500 games ranging from Atari 2600, NES, SNES, N64, PlayStation 1&2, Xbox One & 360.

Turtles in Time is still one of my favorite games. Countless hours with friends crushing levels.
