i have found a great deal for a 91 prelude with a b20a5. its all in great condition. my friend is selling it to me for very cheap. only problem is i can't seem to find any good perfomance parts except cam gears and exhaust manifolds. any help would be greatly appreciated  

if u havent bought it yet keep saving look for a 92-96 lude instead.. my brother inlaw had the 91 lude and it was a night mare to find parts for it but we did he found oversized pistons cams and had it all bored out port polished and fat exhaust when he was done i pushed out round 210 hp but it.. if you did buy it get back at me ill see if he remembers where he found the parts at..  

just about forgot i know monza makes exhaust kits for it headers cat ..all the way back so if you bought it thats a start for you till u find other stuff  

oh another bit of info i found in another forum was this other dude was sayin just cuz its a b20a engine code dont think it will interchange with civic or integra b series parts because the geometry of the lude b series is wayy different and nothin works .. so i still suggest the same thing i did before save up more and get a 92 or newer lude lot more tunability and knowledge aroud for them  

hey I think there are some companyies that make a H22 swap kit for those ludes.  

This is really old make sure you take really good care of it. prefomance parts itsn't that important make sure there is proper presure on the fuel oil and water system. And you are using the best oil that is out there. www.x10lube.com  Is have pretty good products that even the military are using it. They air oil filter that is made of the newest nano filtration material and that is a guarantee.
