Project GT-S Update - The 30 Dollar Radio...


Check out the "30 Dollar Stereo" - equipped with 30 heat pounding...glass shattering watts of audio enjoyment.

Another weekend was burnt up working on my car, and I made some decent progress with some high priority fixes/upgrades.  So far it seems like the interior has been my main focus, and I would like to get things set-up properly before moving on to larger more expensive projects.  Now for those of you that don’t know, I am really into Hip-Hop music.  Nothing makes me happier than listening to Jay-Z or Talib Kweli while cruisin’ around in my ride, so setting up a simple audio system was a must.

When I purchased the Corolla it was not equipped with a stereo, and as much as I love the sound of my Hachi, I was in desperate need of an audio system.  I threw around the idea of picking up a 300 dollar head unit compete with MP3 device control and Bluetooth.  I was almost ready to make the purchase when I began thinking…why spend 200 dollars on a stereo, when I could put that money towards something else?  The more I thought about it the more it made sense, especially considering all I need is a line-in for the iPhone and I’m good to go.



Notice how the stereo does not stand out too much when compared to the stock styling.

So after considering the options I decided to head down to Shucks and get what has to be one of the cheapest radios on the face of the earth.  This thing cost me 29 bucks, and comes ready to rock with 30 whopping watts of power, a tape deck and a radio.  The best part is it has a line-in right on the front, so hooking up an MP3 player is quick and painless.  In all honesty this deck is definitely not the most powerful one around, but for the price I can’t complain.  Surprisingly one of the things I like best about this radio is the looks.  It’s so simple and retro that it doesn’t feel out of place when you’re looking at the interior.  A big stereo with 3D graphics and all that jazz works well in a newer car, but for the Corolla I wanted something a bit more subtle.

Tony (aka Tatakai) stopped by to help with the wiring, and after some trial and error we found the wires for the stock speakers and hooked up the stereo.  With zip ties in hand we mounted the head unit with a simple design that does a great job of keeping the radio firmly in place.  The next step was to build a mount for the iPhone to sweeten the deal, so after picking up a universal dock and remote, I put my MacGyver skills to work after stopping by my local Ace Hardware.  Now I know I may be prone to verbal tangents, but this time I really mean it.



The sleek mounting position makes for a clean set-up that is very user friendly.

Ace Hardware has to be the coolest shop in the world.  Hands down.  If you're ever looking for random pieces of hardware then you can't go wrong with the Ace.  I was honestly walking down the aisles thinking about what I could build if I purchased everything in the store.  All in all Ace Hardware blows away the local Canadian Tire that I am used to back home, and thats a pretty big accomplishement.  OK Tangent complete...back to business.

So with some brackets from Ace and a few random pieces of plastic I salvaged from my apartment I put together a mount for my iPhone.  It’s a simple design that gets the job done, yet it doesn’t attract too much attention.  The white dock does stand out, so painting it black might be the answer.  All in all this system for listening to music is great, and it’s just one more thing to cross off the list. 



Check out the brackets from Ace Hardware and the mounting contraption!


Another thing that was replaced this weekend was the Throttle Position Sensor, and so far so good!  The car idles much lower now, and there is no hesitation during freeway driving.  Additionally my gas mileage seems to have increased drastically, so overall I am glad to have a working TPS.  Now considering that catalytic converter and the TPS are in working order, I decided it was time to get an emissions test, and as with anything there are more hoops to jump through before I can get this baby to pass.
 


Me + Jay-Z + Hachi = Danger.  Maybe I need a strap to hold my phone in place :S

Evidently if your car idles above 1,100 RPM then you are not allowed to take the test…and this Corolla just happens to feel comfortable around the 1,150 RPM range.  Honestly I was 50 RPM away from the limit, so determined to pass Adam and I investigated ways to drop the idle.  We started with the idle set screw and soon found out that it was already maxed out.  We then messed around with the TPS sensor to try and lower the idle, but it was almost like the car didn’t want to idle any lower than 1,150.  After consulting with the subject matter experts in Adam’s bay, we discovered that the distributor timing might be slightly off, thus causing the higher idle.  We will be fussing around with this during the week, but if anyone has some ideas on how to drop the idle make sure to post a comment.  Any help is greatly appreciated!


Check out the throttle position sensor doing what it does best....sensing.

So what’s next?  Well a nice pair of reasonably priced racing seats would be a great addition, along with a few more touch ups to really finish off the interior.  Things like painting the interior black and building a cover for the trunk are definitely on the radar--it’s just a matter of deciding what needs to be done first!



The GT-S lays to rest in the underground lot...waiting patiently for a chance to slide.

If only money was not an option, eh?

Just a rough guess on something that might want to be checked:

Is the throttle hung a little bit?
=== So, that's my useless tidbit of info...since I didn't spam your pm box with it, i figure i might as well say it here:

could try pulling the throttle body off and giving it a good cleaning, and maby replacing the return spring.

mass flow sensor should be checked, A-F ratio meter as well.

She's coming along nicely!  But really, Ace HW > Canadian Tire?!?  I'm not sure about that...  Maybe I'm hitting the wrong Ace, but the Canadian Tire stores I've frequented were the most amazing stores EVAR.  Seriously, one stop shopping for all but the pickiest of consumers.  If you're on a roadtrip in Canada there's no better place to get what you need no matter how bizzarre the request.

In auto shop at my school we had a Baretta that was idling high and nothing was working so we tapped on the throttle body a few times and it droped significantly. I really don't know if that will help but who knows give it a try.

Make sure none of your vacuum lines are leaking.

Adjust the TPS and it will bring the idle down significantly. ;)

Ha, nice radio. I've got a JL audio E1200 amp and a premier sub laying around in the garage waiting for me to get a deck and speakers to throw it in the corolla.

As for the idle, my car feels liek it starts to bog and die out if it goes under 1100, I don't think i'll be passing emissions. No worries though, Thurston County doesn't care :)

Nothing wrong with using the iPhone to listen to music in a car :)

So I was able to get the idle just below 1,000 RPM (with the help of the subject matter experts of course) so I will be trying the emissions test tomorrow.  Wish me luck :S

I also did some checking around inside the throttle body and it does look pretty dirty to say the least.  I will probably be cleaning it out this weekend if I can pull myself away from GTA for 5 minutes (not likely).

And yes Ace Hardware is better than Canadian Tire and I'll tell you why.  Canadian Tire has a huge variety of things to buy, but specialty parts and gizmos just cant be found.  For example I was looking for a specific screw with a very specific thread pattern.  If I would have looked at Canadian Tire I would have never found this screw, but the dude at Ace hardware hooked me up right away without hesitation.  So I'd say Ace Hardware has a wider assortment of random things you might not find anywhere else.

So there just happens to be a drift event happening at evergreen speedway this Friday...all I need is a helmet...hmmMS
