My brother and I just finished a turbo/IC swap on his 02 WRX wag, and now have the stock injectors laying around, I believe they are 420cc. I know very little about injectors, and was wondering if they could be modified to work on my 05mcs? I was planning on going with Helix's 380's since they are 20 mins. from me, but thought I should explore this first. If not we'll slap em' on ebay, no biggie.
