I will hae to ask around about that LPG conversion, few colleagues drive lpg cars, honda legend, land rover discovery 3 and 4, mercedes ML, and my boss bought dodge ram 5,7 hemi two days before i got my civic. It mainly depends on the guy/garage that installs it and tunes it, because these all drive fine, but my brothers skoda felicia is just weird, sometimes it accelerates just ok (for 50kw engine) and sometimes you have a feeling, that if you started pushing it yourself you could get up to speed quicker.
I am not that worried about 2nd gear, since i am not really launching it, nor drag racing. Just occasional 2nd/3rd gear pull to pull up to traffic on hwy and 4th/3rd gear downshift when overtaking.
I will contact him, when i will be closer to doing the swap,for now i have read some guides and watched videos of people doing that swap on ITGs.
