I have a 2003 civic d17 non vtec sadly. I cant afford the k swap yet so I was wondering if aftermarket injectors coil packs an maybe light weight pulleys would help with a little more *** in my turd..? I know vms makes coil packs but I'm not sure if the injectors will work

 

Why did you make two threads and ask this twice ??? The lightweight/under-drive pulleys may pick up 1-3 HP. Fuel injectors and coil packs will do nothing for increasing performance... as I stated in your other thread.

 

I doubt the aftermarket stuff would make a difference. Just doing routine maintenance may make a noticeable difference. New plugs, new air filter, remove intake resonator stuff, 0-20 syn oil. Start saving and planning for build up or even second vehicle. Make make sense to buy a civic that already has motor swap, or someone else's incomplete project car.
