If your gonna build a full race engine and want to start with brand new parts to get the job done I found a great site that sells blocks, cams, rods and pistons to suit your B and D series engines. RS Machine
I found a website today that shows the extensive engine build for a 1989 civic. Now this is the model older then mine but still have losts of great information about the B series Engine. And whats even better is the main website that has even more information. ENDYN Energy Dymanics
I found writeups on B Series and D Series honda engines on wikipedia and so far i got that B Series are more expensive to build then D Series but besides that it’s still hard to choose, ether the B16A 160HP or the D16Z6 125HP. Now the B16A has more HP but cost might be a problem. Time to do more research.
I found this great B Series Honda engine writeup by Honda Tuning Magazine. It goes into detail about how to mod these engines and what parts are great to swap in the B series for most power.
