Funny cause im ready to throw 400hp at my B16A very soon. Your gonna need to sleeve the block, ill tell you what im using,maybe itll help. Bottom end: Darton MID sleeves,Wiseco flat top pistons(stock bore),eagle h-beam rods,ACL Racing crank and rod bearings, Eagle esp crank,AZ Race machine girdle(w/ GSR oil pan, pick up, baffle), Endyne racing oil pump,Endyne egr system. I just put skunk 2 valve springou s and titanium retainers for the head(for now). You gotta upgrade the fuel system too: fuel pump, 650cc injectors, high volume fuel rail .Need biggger axles. If your tranny doesnt have an LSD, you should upgrade. Unless you like replacing snapped axles all day. Not including the JDM conversion and the time some a*****e on ebay stole $2400. I'd say i've spent about $13 G's on the motor/tranny setup. I did all my work so you should expect more if your not doin the work yourself. PM if you need help or recommendations
