Default My 2012 si

Not much love here for the 9th gen civics that I see, I figured I would try to contribute and help that out some! I have had my car for almost 2 years. I have been a member here forever but I do not post a lot, however I would like to become more active. here is where I started (consider this a late build thread)


this was in January of 2014 bought it used from Honda as a certified pre-owned. drove it stock for about 2 weeks and it was horrible. 9th gen civic's stock are seriously one of the most boring cars I have ever owned. so I had to start tweaking some things.


installed D2 coilovers to help the tremendous amount of body roll and 4x4 look.
A few weeks later I ordered a set of advan rgII (used but new to me)
and a k&n short ram intake. and drove to Atlanta GA for the spring import alliance





so after driving it this way for about a month and a half I decided it was time for something else. I found a way to make a J's racing axle back fit on my car that was made for a FD2.


next was something to make the car not look like a odd colored egg with wheels. added a mugen style spoiler from kplayground and side skirts (had to use fake parts because real ones are not available)











had the spoiler middle piece painted black to accent the rear bumper all in all the parts weren't that bad of quality. the spoiler moved a lot while driving due to wind but it stayed sturdy and in place. small things over the next few months just removed window tint, added oem visors and drove the car.





after some research and talking with vit - viper I decided to go the hondata route and have a tune done on the car. installed a catless downpipe and swapped intakes to a takeda momentum cold air intake. the feel and power this car has after vit got ahold of it is amazing. no more rev hang, higher redline and throttle response is on point and has continuous power through out the whole rev range. drivability is just there now, and the car is a blast to drive. FINALLY! mine put down a little over 200 to the wheels.






next was a front lip, I waited forever and finally decided it was time to buy one. bought a "modulo style lip" again no real parts are made for these dang things. sold my advans and bought a set of desmond regamasters.






finally got the look I have been going for and with it being fun to drive with power and looks. the only fall back is that the regamasters are an older wheel and not tpms compatible. any other 9th gen owners may have this issue but with no tpms sensors you can not turn off traction control. therefore making it less fun and at times harder to drive if you want to turn traction control off for a spirited drive. oh well.. still working on that one.



this is how it has been for a while. just driving and enjoying it.






sorry for the long ramble and life story. hope everyone enjoys!

That is a great looking car! You don't by chance have any more photos of making the exhaust work, do you?

Such a vast improvement over stock

For the TPMS issue, I found this on another forum...

It took some investigation, but there are universal TPMS sensors that "look" for the frequency in the car, then lock onto it. My mechanic has used them before.

He solved the issue of mounting in wheels not compatible with TPMS sensors by mounting them with a strap, that is like a giant hose clamp. These are made by Schrader and Dorman for around $20 each.
Hope that helps! Good luck

No sir I do not, however if you get an axle back off of an 8th gen basically just hammer on the inside of the body a little to make it fit and finagle the hangars until it sits right. it just takes time and a little redneck engineering.

2014 is when Honda went to the indirect TPMS system on most Civic's, using the ABS as a TPMS. An indirect system counts the RPM's of the tire/brake disc in the same way ABS systems work. When one rotates different than the others, the light goes off. There is no actual sensor in the wheel, but often the system does have to be reset to learn the new diameter of the tire. It's probably one of the best systems out there, in my opinion.

Direct TPMS is most widely used on American and Japanese cars and uses a sensor that is incorporated into the wheel and most often part of the valve stem. This system is counting the tire RPM's, sending a radio frequency to an on-board computer.

My thought on TPMS, is that MOST TPMS systems out there are comparing tire pressure between all four tires before triggering a light. The way TPMS is being sold to individuals is that the TPMS light will tell you when you need to adjust air pressure in your tires or you have a low tire. People are using this to gauge the air in their tires, not manually checking them as they should. If all 4 tires are low on pressure, the light never goes off because the system doesn't recognize that. The system is looking for 1 low tire. I've instructed teen driving schools that teach kids and teaching how to check air pressure is part of what we do. Most kids think 'if the light is off, we are good'. Not the case at all. When we check, tire pressure, almost always the pressure is low. Always use the door placard tire pressure as indicated by the vehicle manufacture and adjust up, if you are going to use a different pressure. *end rant on TPMS*

There are many clone-able systems out there in todays market that work well for people with multiple sets of wheels. Basically, you use a device to scan your factory TPMS codes and then load them into a new set of TPMS sensors, so the vehicle never knows that the sensors are changed. You would use a set of clone-able TPMS for every set of wheels you want to use with a TPMS system. This is probably the best option as it will retain TPMS. Clone-able systems are also often based on a rubber valve stem with a tiny sensor, and can fit into a number of aftermarket wheels.

As for other ways to re-engineer your TPMS:

Band sensors do work, but not always best. Sometimes, when a vehicle that isn't designed for a band system switches to a band system TPMS, the on board computer has a problem reading the sensor. This is why Ford actually went away from the band sensor a few years ago.

Also, TPMS capsules. Google image search it But by doing this, you are only defeating the TPMS light.

Why would you buy a car that you find so boring?

Does the kplayground rear spoiler mount to the stock holes in the trunk or was their additional drilling needed?
