i have a B18 gsr engine in my 99SIcoupe, what could be robbing my car of horsepower or what could i do to get out all that potential? it doesn't even spin in 1st gear.
could a bad O2 sensor be doing that?

Weird way of gauging the power output. ::shrugs::

Is it possible the clutch is slipping?

 

weight reduction if your up for it. a bad o2 will make you run rich so yea im sure its robing some power.

 

timing! check your ignition timing. My car ran like **** and had no power when i had just put the dizzy on and had not set the ignition timing.

well a SI could spin in 1st..... and i put a new clutch in.

 

check timing,plugs and compression

 

any car can spin em in 1st.. my old vw fox would roach em in 1st..

:shakes head:
dont consider it lose of power consider it as ur gettin good traction.....

 

i have a gsr in mine and it never spun em in first until i put the skunk2 manifold on it, check the intake manifold for oil, when the company i bought mine from shipped it they tilted it and oil ran into the throttle bodie and intake

 

Slow on the butt dyno? Or slow on a real dyno? Butt dyno is a matter of perception.

 

Yeah I would recommend checking the timing. It's pretty easy to do. When I changed a head gasket I started the car before getting the timing straight and it just sounded weak, although I never drove it like that.

 

how can it not spin up your tires? Are you expecting your tires to spin when you floor it from a rolling start in 1st gear? your stock GSR in your coupe...let alone an SI coupe...won't spin your tires this way unless you have shitty tires.

do a compression check or do a dyno run. or both.

 

I didn't no a car had real power cause it can chirp tires... damn i shoulda keep my dx motor cause i could catch 2nd sometimes just a little am humor
