I have an 89 Crx with a dohc zc vtec. Im looking to swap this next week but im torn on what to do. Would it be advisable to go with a b16a1 or b16a2. Would the extra investment in the a2 be worth it? Also on a side note i was thinking about gutting my rea interior. but metal looks ugly in my opinion. have any of you seen anyone sprayon bedliner the interior of a car?
