2G Missing Cam Angle Sensor

[Fullthrottle7]

I was out cruising around in my 95 Talon TSi last night with some guys and one of them with a first gen GSX wanted to look under the hood, so I popped it for him. After looking at the engine for a minute, he gave me kind of a confused look and informed me that my cam angle sensor was missing. He then showed me his engine, and sure enough, there is no sign of it on my car, just a hole on the side of the head. I tried to search for more information, and what I gathered is that this sensor just sets the base timing for the engine. Is it bad for my car to run without this sensor, or will it be fine as long as the timing is set correctly already? The car seems to run fine now, but I am not that mechanically inclined, so I wouldn't know what to look for if something small was wrong, like having the timing off a few degrees.

Correct me if I'm wrong ( I'm not very mechanically inclined) but doesn't the 2g have a crank positioning sensor instead of a cam angle sensor?

I have no idea, the kid just said it was a cam angle sensor and showed me where it should be. Its on the back left side of the head when looking at it from the front of the car. There is a hole about 2.5-3 inches on my car where his car had about a 3-4 inch round sensor hooked up. Would the crank sensor do the same basic thing as the cam sensor - set base timing??

You have a cam angle sensor, it's just that the 95-96 cars had the CAS on the cam gear and not the drivers side of the head. ALL 1g's and 97-99's had the CAS on the passengers side.

I've got the same thing on my 95 gst, so my question is... How do I advance my timing? It's at about zero right now. Can't find anything on it but want to get it all set right

oops, that's what I meant.

Like the 2gb's, you cannot adjust base ignition timing on the 1995's and 1996 engines.

the only way you can adjust your timing is install a 1g CAS and wire it up to your Crank angle sensor and your Cam angle sensor, the 1g CAS does the job for both your crank and cam sensor and you can adjust it,, do a search for converting it and there will be tons of info on the subject

I know this thread is old but my question is so if my 98gst has it behind the cam gear then my motor is from a 95-96 or it is a 6bolt? wassup texas gst im from lubbock.

The head does not determine whether or not the car is a 6 or 7 bolt engine, because they're interchangable. It merely lets you know you're more than likely on a 95-96 head.

If you want to know what kind of bottom end you have, you need to examine your oil pan.

Not sure if this applies to 2G's or not but this is how to tell between the 6 bolt and 7 bolt on a 1G. Anyone know if the oil pan trick is the same for the 2G's?

heads are not classified as 6 or 7 bolt. they are 1g or 2g as the 1g 7 bolt has the larger intake ports also. it was in 95-99 (2g) that they changed the intake port design.

 

[banishedmunk]

please explain the difference between the 2ga and 2gb head design. the plug that is used for the CAS is the same size as any of the CAS' 1g or 97-99. unless you are refering to the cam gears

Sorry, i was visualizing the head swap procedure from RRE, thinking the bosses for the bolts for the passenger's side mounted CAS were not there on the 2ga heads.

thanks I was confused.
