Well, just got done doing a compression test after having the HRC Stage 2 kit on for 6 months....My dad and I used a push-in compression tester and if he moved it around certain ways he got different numbers, but anyway, here's what we got:
#1: 172 #2: 162 #3: 175 #4: 180
Based on the fact that if he moved it around a little he got some better numbers are guessing that my actual compression for all 4 cylinder is about 180 in all of them...maybe a bit better. So uh, I'm guessing I don't need a rebuild right now...although....I am very tempted because I want Stage 3 and 12 psi daily! }>

#24875, "RE: Compression numbers for my car." In response to Reply # 1
I've been boosting about 5 psi for 4 months and 6 for the other 2. I had a MBC, a cheap ass one on and I had it set to 8, but kept getting spikes of 12, so I turned it back down to 6....so about I'm at 6 psi now. Not much, but it's still forced induction on a completely stock motor with 80K on it.
