rb20det timing- actuall directions please

[blues14]

Does anybody know how to correctly time an rb20det? I searched and found nothing.

Warm up car

Make sure idle is 650 +/- 50 rpms.

Unplug the TPS (not the idle switch, but the tps, has the cord hooked to the plug coming out of the sensor)

Hook up timing light around the loop at the back of the engine coming out of the ignitor pack (black wire loop)

Check timing, if way off, then flip the way the thing is connected around that loop

Set to 15 degrees for manual trans, 20 for auto with car in neutral, do so by loosening 3 bolts on cam angle sensor and rotating it left or right.

Tighten CAS

Plug tps in and rev engine, then unplug TPS and check again to be sure it is at 15 degrees with idle around 650rpms.

Shut off the car and uplug everything the timing light, plug tps back in and unplug battery for 10 mins.

Hook up the battery, restart the car and go drive it hard for a few minutes (within reason of course).

thanks man, my car is idling at 900-1,000 rpm right now. it should be around 650-700?

[Eikon]

yeah.. 650 to 700 is about right.

You most likely know this already, but just in case... you can adjust your idle RPM's with a flathead screwdriver by turning the screw on the AAC.

I had mine at 15 but moved it to 20 seems to be A ok. Not pings or detonation .

And if you do this, you have to unplug the brown plug from the AAC first, then plug it back in.

Thanks Eikon, I didnt know that. Hell, I dont even know where the AAC even is:) It's nice to have a forum where questions are answered instead of people just flaming and giving eachother a hard time. after all, that is what a forum is for. thanks again. also, is there a certain type of timing gun that works better for this ignition setup? My freind that works for Nissan is coming over to help me out so it would be nice to have the right tools ya know.

[goofynick6]

Inductive works best, then you don't have to mess with extra wires and removing coil packs..

[blues14]

are you positive on the timing is 15 deg on mt and 20 deg on a/t?

I have looked at some other sites and they have it reversed.

Yup yup. I have an Auto ecu in my 5spd tho not sure if that made a diffrence.

[blues14]

would it be ok to have it set to 18 degrees to be in the middle of the road?
