So im still new to civics but read alot on here and similar forums and am starting to plan which b series swap I would want. All input is greatly appreciated. Objectives: Primarily a fun daily driver that still gets around 30-35 mpg combined, and less importantly could be raced later on. wHp anywhere from 150-180, and enough torque to not make it not feal gutless around town and is reliable and will last me long term (5-10 yrs). I just wanna smile everytime i drive it. Budget: This isn't set in stone but somewhere around $6-7k would be the max for the entire car, but preferably less..including wheels and suspension. Options: in order of most viable to least. GSR b18c1-over all solid choice but spendyish LSVTEC-assuming its build by a reputable shop, with good components (What kind of specs hp/lb/mpg can i expect on average as i realize their are tons of variables?) k series...I know the least these but much more expensive b16 variant..-cheaper than b18 but less power, better mpg I would think? b20 vtec- similiar to lsvtec but less potential combinations and more expensive but more torque (What kind of specs hp/lb/mpg can i expect on average as i realize their are tons of variables?) So as you can see im trying to find a nice balance of power/mpg/reliablity/daily drivablity/affordability so if you can let me know your expeirence with any of these engines in the above domains especially price I would love to hear it. Other general questions: -does raising compression also raise effeciency(hp/tq/mpg/airflow) or just power and thus lower mpg? -Do jdm engines(obd1) pass emisisions in portland, Or or states? What is the strategy with deq? Any reputable shops or references for the North West? And in general it seems like the best strategy to find deals on built cars is to buy them complete, rather than import engines/building them and have a shop install, is this true, exeptions?
