H22a4 compression for FI
I just did a compression test on my 97(base) prelude with the h22a4. The readings came out as 180,175,175,175. My question is, is this a good enough compression to safely run a turbo at 7psi. And its all stock internals right now. I believe the honda says the nominal compression is 185, is this correct?

That's good compression, but there's a lot of other things to consider if you're going to turbo a car that was not meant to be boosted.
