I have a b18c1, but my dad/bro/ family friend and I built a b18c for roadracing, I learned quite alot that I did'nt know before. Not newbie stuff though.
Personally, I think the b18c jdm type r motor is the best b-series motor ever made. I don't care if an LS shortblock has 38 more cubic centimeters, the LS block was'nt built for racing, the type R WAS. It's the perfect motor, and honestly, in roadracing you don't neven need any mods on that engine to go faster.
The LS shortblcok will probably have oil pickup problems also if the oil line is'nt changed, whcih can lead to some problems also (KABOOM!).
My car is a GSR, but I'm tryin to get the body to look like a GS as much possible. I even thought aboout putting the brake light in the rear window.
I know I kinda babble too much, but I'm just happy to fin a good forum about the GSR
