hey i got my new tranny put in under warranty and i put in a new stock clutch and jwt flywheel, when my car is just idling and i am not pressing the clutch it sounds like chattering noises, like metal moving around in my tranny is this normal, and going off the line the car is harder to get off the line its like kind of shakie, is this normal havent been able to really floor my car since i just got it back but i really would like to know if something is wrong or not thanx guys

 

Its the new flywheel. Most of the time when you get a performance "thing" for trannies its gonna make more noises.

 

ok im just making sure nothing is wrong with my car, having been able to really go through the gears hard bc the new clutch tranny flywheel but ive got a feeling its alot faster, also the z mechanic that did my car says he advanced the timing, does anyone know if i would see hp and tq numbers higher on the dyno b/c of my flywheel??

 

You can't advance the timing on our cars unless he flashed the ECU. We use coil packs that are fired by the computer so there is nothing to adjust to advance the timing.

 

i thought u could advance the timing on the stock ecu?

 

yea the noise is your flywheel... had the same thing on my stillen fly. you'll get used to it.

 

i was told you could advance the timing a while back when i asked on this forum and the mechanic says he did it dont know for sure, anybody ever find out if you can see dyno numbers higher with a lightweight flywheel???

 

Yes you can advance the timing at Nissan. Never did a b4 and after dyno, not worth it when the dyno costs as much as the mod or even more.

I think I lost my 'advance' when I installed stuff on my car. I disconnected my battery for a while and I think it might have reset my computer. I have been to lazy to take it back and see if the advance is still "present".

 

did your car feel any quicker after doing the timing, and also the flywheel will i see numbers from the flywheel on the dyno??

 

most nissan techs are idiots

they don't know much other how to put on basic parts

they can also hook up their computer to show you any codes

they have no clue usually how to actually adjust your ecu/timing even though it is possible

at least that's how it is around the local AZ dealers i've been to - not saying they're all like that, but i'm usually not expecting knowledgable people to be working on my car

 

Yeah but this guy knows alot about the 350Z. He is the only tech that works on them. Yes I did feel a difference! Not sure if it was my imagination or not though.

Be weary if your gonna do it, cause they could say they did it but really didnt. And no you will not see numbers from the flywheel.
