b series suffer a rough 15% drivetrain powerloss, someone correct me if i'm wrong. so take the horsepower it makes and subtract 15% and you'll get an rough number of what it is at the wheels. jap motors have more hp because they're higher compression i think. if you are thinking which motor to get, get the gsr motor. b16 is a torqueless motor and feels like a d series until vtec in stock form.

^^yep, most FWD drive vehicles lose ~15% of their flywheel rated power at the wheels.

that seems about right for my torque figure

i got a jdm gsr b18c

145whp

and

117wtq



but my hp figure seems low.....

probably because of the small stock exhaust


thanks guys

im thinking my exhaust is whats keeping the power down...
paul at splitfire told me to change the exhaust and header and ill get around 10whp

could valve lash be holding back the power?
or fuel filter?

yeah a good header and 2.5" exhaust will help.
When was the last time that engine had a tune up?

b16a:141whp 101wtq

b18c1:150whp 109wtq

b18c5:162whp 113wtq


these are close to real world specs with no mods.

i know for a fact that with the cams that you have a proper tuning you can make 180+whp. trust me. once the 16 starts to sing above 8K they make the power. its about the rev's with the small displacement motors. and, a 4.785-4.9 f.d. in an absolute necessity if you plan on hangin' in the 9K area. i love 16's. that peak soooo late.

looks like i got strong torque, 117

but my power is a little low, 145


it kills me now cuz i wanna find out whats holding the power back, but i gotta wait for a good exhaust and header to come along
