is a civic hb with a h22 engine reliable?

 

No. If it hasn't catastrophically exploded by now, consider yourself lucky.

 

Of coarse it is reliable. Why wouldn't it be? Is a Prelude reliable? As long as the swap is done correctly, there are no wirning problems, leaks, and your not reading any codes it will run fine. I had a bone stock h22a in my eg hb for about a year. I never had any mechanical problems. It ran great. The power was awsome. I liked the h22 so much, that about 5 months ago I decided to turbo it. I still have it to this day. I have it in the shop right now putting in a built block so that I can turn up the boost.

LOL MR MILANO!

 

why wouldnt it be? unless your boostin the h22 like 2 bars on stock internals or the swap wasnt done correctly
