I got a set of used OEM fuel injectors from a parts car (04 WRX). I'm thinking about decapping them. Those who did it before, did you have to go get them clean and other stuff afterwards or are they ready to install with new o-rings, gask and tune without any other requirements? TIA
Unless you were really pushing the limits of the existing injectors i would just have them drilled, cleaned and flow checked. I did this with my itb converted spectra5 because there was literally no kia/hyundai aftermarket support at the time
Independent throttle body kia spectra5 with the 2.0l beta 2 engine (yamaha r1 itbs iirc) Was running an early mega squirt ecu. Not my actual car but the same silver and factory lip kit
it sounded awesome, still not terribly fast but back to the original topic I had to get some injector caps drilled slightly larger, cleaned and flow tested to make that setup work. I caution though that the cost of doing that might exceed buying upgraded used injectors from FB market, craigslist, etc. I did mine in a college CNC lab so it was technically free
