need help w/ sr

[justinNISMO]

It needs to warm up,before it runs but after warming up it runs like crap! It is spitting and sputtering. I tried timing it and had it on 16 degrees off tdc, and after it was set at 16 degrees tdc I would test and no power. I don't know what to do, I am losing performance and fuel mileage sucks! Need help deseperately. Thanks JustinNismo

What procedure did you use to set timing?

Also, how warm is it getting? Do you have a gauge?

When driving does it feel down on power all the time or just at a certain RPM range. Does the turbo spool a little later or really early compared to other SRs?

If you can do this safely, drive the car down the street, turn around, run it through 1st gear and turn the car off immediately. Coast it into your driveway, and pull the spark plugs. Post a picture. Do not let the car idle, turn it off as you accelerate.

Does the car smoke at all, idle, driving, and/or acceleration?

Does it hesitate?

that sounds kinda like how mine runs too, does yours idle really low/rough? what should the spark plugs look like after doing that test?

[justinNISMO]

i first take the CAS out set the motor @ TDC then i line up the marks that are on the CAS the dot on the left with the line then slide it in with both dot and line facing up, then use a timing light and set it at 16 degrees off TDC which is the second notch from the right. what would i need to look for with the spark plug?

did you warm the motor up all the way, with the tps unplugged, then have the base idle set to 700-800 rpm before adjusting the cas?

my Black Top ran like crap before when i first installed it. basically what i did after setting the base timing (15±2° TDC), is that if it still ran like crap, try to raise your idle. on the intake manifold, there should be a idle adjustment screw there, turn it according to the idle, and see what happens. after fiddling around with it, my car ran fine.

...now that winter is upon us, i think its time for me to redo me idle again...hah.

well, please someone correct me if im wrong, and good luck!

if the motor is basically stock, your idle should fall within that 700-800 rpm range. Raise it higher and you'll just screw your mileage with no added benefit. You'll see some people (like those FC guys with race ports on the street) that need to bump up their idle past 1k otherwise it'd just die on regular idle but for a stock setup, bumping up the idle is just masking another problem. Find the real cuplprit instead of trying to work around it.
