my nissan 200sx

Jan 14th, 2003, 04:06 PM

I have a nissan 200 SX SER, and i bought it stock
its a '96
I have installed some HP motorsports headers,
timing to 17*,
changed muffler and exhaust to 2 1/4"

........but the problem is that my car now has 105000 miles!

so i'm not sure if it would be ok to be tuning my car for more power????

I wouldnt think having 105k miles would stop you from doing anything. Most SE-Rs probably have more than 100K miles. And thats never seemed to stop anyone.

another problem i have with my car is that
suddenly one day i started speeding my car, and in the first 3200 rpm in every gear change,
there is a loss of power, and after like 3500 rpm the car has alot of power

sometimes the car seems like its going to turn off....thats how much power it feels to be lost.

what can it be?

Did you try a good tune up? Air cleaner, plugs,ext.

Hey Don Ernesto:
On what Gas are you runing in El Salvador??

the thing is that I already did a tune up, changed my plugs to NGK, also did a injector clean up, and changed the gas filter

and the cars performance got better, but still once in a while you can still feel in the first 3500 rpm a loss of power,

it feels like the car doesnt respond ....(do you think it can be the computer??)
the gasoline overhere is 92 and 97 octanes

o2 sensor

o2 sensor??

could you explain what exactly is that???

yu yevon · Jan 15th, 2003, 10:07 PM

thats an oxygen sensor usually located on the exaust manifold. But i dont believe thats the reason why for the prower lost at 3500 rpms.

I'm not sure if your engine has it but try cleaning out or bypassing your EGR. I bypassed mine and the stalling or lack of power under 3000 rpms went away. I'll clean out mine once it gets warmer over here.

CarloSR · Jan 16th, 2003, 12:33 PM
