Im not to knowledgable when it comes to working on cars but I would like to check and adjust my timing. Ive read a little bit on how to do it but nothing goes into detail. If someone could give step by step instructions that would be great. I dont know things like what i connect the timeing light too, where are the timing marks, and where is the thing i turn to adjust it (the rotor or something like that)? Thanks

OK dude you seem to have little experience under the hood so this is a very simple,very cheap,(like $0.00) mod.I will say most people would probably say go buy a timing light but my way is fast and it works.

First find the 2 bolts on you distributor.
losen both just enough that you can move the distributor.
Now move the distributor towards the firewall,or towards the windshield. move it until it can go no further. tighten bolts and go out and enjoy a big diffrence.

its311pete; That is the most irresponsible advice i've read. I hope that you were kidding and mpg9999 has not followed your advice.

Just go to SE-Rnet and search for timing adjustment, (I don't know how much more in detail the instructions can get because they are way easy to understand.) If something in the instructions don't make sense, then ask us here on the forum. Alot of people have been adjusting timing on their SR20DE's as of late, so I'm sure there will be plenty of help available.

You probably won't be able to see them if the car is running without a timing light, or even if the engine isn't running, they could be on the bottom side of the pulley.

They are located on the edge of the pulley, visible from the top. Just look for the metal needle pointing to the main crank pulley, that is where they will be.

Where is my TPS and what does it look like? (BTW, I have a 91' Sentra SE-R)</font>
The throttle position sensor is located on the back/right side of the throttle body (towards the firewall). If you don't know where the throttle body is, it is connected to the end of the intake hose (not the airbox end) and has 4 hex bolts holding it to the intake manifold. Your throttle cable is indirectly connected to it as well, and there is only one sensor on it, the TPS.

Thanks, I finally found them and checked the timeing, but im not sure what it is. I think its at 15, but there are no numbers. There are 6 white lines and its on the 5th. Does that mean its at 15? One more thing. After i disconnected the tps and started up the car (after it was warmed up), my idle was at like 1100-1250. I reved the engine but i couldnt get the idle below around 1200. Ive noticed my idle there befor but after i start driving it goes down to like 800 so i drove around the block and when i pulled into my driveway it was back down to 800. Anyone got any ideas why this is happening?

the timing marks are on the lower pulley by the coolant reservoir. just connect the timing light clamp to the #1 cylinder and aim the light down there. Mine were faint but easy enough to read.

Yeah, my buddy nismoser had the same problem the other day. You have to find the idle adjust screw, and adjust your idle with the tps disconnected. The idle adjust screw, is on the passenger side of the engine, around the #1 cylinder, your gonna have to dig for it, but its there and reachable as far as ive been told. Once you adjust your idle to 800, you will be able to get an accurate reading and you will be able to adjust your timing accurately. Hope this helps.

I done the follwing,(with I told to MPG999) to my Classic about a year ago and have had no problems with it....My cousin with a 91 Classic and another friend with a NX 2000 let me do this with there cars and both loved the diffrence...hell my cousin just ran a 9.989 in a 1/8 bone stock with his classic this fri. I am not saying this is the best way to go but from my expirience this is a quick and easy way to get some hp's. I would agree that the 17 degree is the way to go but when you are in a parking lot and you are tring to get a little more out of your SR20 this is OK. Like I have said I have been running this way for a year and have had ZERO problems with this setup. I have asked for info on what it might do, good or bad and no one has responded and it seems to really help.

So here's my question... Is do the marks go from 1 to 19 1 being closest to the firewall and 19 being closest to the front of the car? or the other way around? I adjusted mine to what I thought was 17 my pointer is between the 1 and 2nd mark in towards the front of the car.. also my distributor is almost all the way towards the grill (front of the car) I read you advance away from the firewall.. These posts seem to conflict with SE-R.NET ????? Help as now i'm confused..
