Which of these is better quality? I have heard both good and bad about pwr..mostly good. GReddy i havent heard too much..but most has been that they are average too good. I need this intercooler for my 90 prelude..so it needs to be fairly small..the 31v i'm looking at is for a civic..so good size..and its a good price..cheapturbos.com has good prices on the pwr's too...anyone have experience with these brands..quality..etc..thanks a lot
