I did get the 08. Got the interior mostly clean. I forgot to clean the seat belt, which should fix it not retracting.
The shift knob had so much gunk in the numbers I didn't know they were red. I need to do the drill and sand paper trick to make the metal top look nice.
Once I get all the maintenance done I have a few plans for the car.
First I'll probably get a non-nav radio and modify it with an android auto unit and keep the stock hvac controls. The Metra kit for this car is hideous. Then I will probably do some aesthetic mods. I really want to wrap the car white or green, lower it a little, and get new wheels. For performance mods I'll probably get an intake (for noise), pullies, maybe a header, and a flash.
Congrats again on your purchase!
Drill and sandpaper trick? I've not heard of this...
Lowering: Lots of options depending on your goal and budget. Personally I have Tein Flex Z. These are budget coilovers for sure but at least made by a reputable company. They feel pretty good with some increased preload, rebound is a little stiff but there is definitely worse being sold for a higher price.
Wheels: I highly recommend losing weight here, it will do way more than pullies. I recently picked up some used 17x8 +48 wheels that weigh about 16lbs each, coupled with 235/50/17 Continental DWS tires (mild fender roll required for this size, 225/45 would work without a roll) my wheel/tire combo went from 49lbs (OEM wheels) per corner to 39lbs per corner... And the difference is night and day.
Intake: You can do a DIY cold air that deletes the huge resonator box and uses stock airbox and piping, costs you nothing but some time, and increases both noise and power. The power probably comes from lowering your IATs by 30-40°F. I would also recommend doing a throttle body coolant bypass to further compliment the reduced IATs. Both of these mods together should cost you less than $10.
Pullies: Tons of options here, but ralco pullies are cheap and OBO on eBay. They also make OEM sized so you don't have to underdrive your accessories if you don't want to.
Header: Serge bo here in the forums builds an excellent header, that fits to OEM catback without any chopping or welding. He also includes a test pipe with flex joint if you want to delete your catalytic converter.
Flash: Serge bo can also flash your vehicle remotely, and all accounts say his flash is superior to the Hondata flash, which requires downtime/shipping of your ECU.
Hope this helps!
