im about to do this custom intake thing that this dude with a cool ass P10 I saw at work did and showed me how to do but I kinda forgot, ok, u know that lil metal chamber with the temp sensor in it next to ur airbox? I'm thinkin I gotta take the chamber off and put the filter there and take the sensor out and stick it into the filter, but if I do that will it mess somethin up?? thanx guys !

There are two sensors...If facing the engne, to the left of the air box is the MAF (dont mess with it) and to the right of the airbox in the tube that comes up from the wheel well is the air temp sensor. Ive seen this moved to the top of the filter and even into the intake piping...just my two cents...

You can't remove that. It is the MAF. Mass Air Flow sensor.

The filter has to go after the MAF no matter what. The MAF tells the ECU the amount of air coming into the engine to adjust the air/fuel mixture.

Go here to see a 'ghetto' style intake. Very well done too:

The other plastic tube goes to your AIV. It is ok to remove that. Follow it to the other black box mounted above your exhaust manifold. You can remove the entire tube then get a small breather filter to go on the AIV where you removed that tube.

Or you can completely remove the entire AIV stuff if you would like to.

Here is how:

This is the AIV hose. On all 5-6 AIV systems I've removes, of them had a
LOT of water in the AIV valve on the front of the valve cover. Just remove
the system.

1. Remove the line that goes to your air-box and duct tape up the hole on the
INSIDE of the air-box. It's nice and flat in there so the tape should stay
very well.

2. Remove the AIV valve and small resonator box on the front of the valve
cover.

3. Remove AIV hard line going into the exhaust manifold. Cut it off with a
hacksaw or something close to where it screws into the manifold. Hammer the
place where you cut flat and then fold it over about 3 times. Should end up
looking like this http://www.sr20deforum.com/geekout1/DSC00009.jpg . Screw
that back into the exhaust manifold, which effectively plugs that hole.

4. Trace the small hard line back that was connected to the AIV across the
valve cover to a vacuum line that goes into the intake manifold. Remove the
hard line and plug the hose with a bolt/screw.

Voila! No more AIV system and no more water in your intake. :)

He probably has a '94 or newer G20. They have a air temp sensor. Some guys who do custom intakes will just hang it on the side of the air filter. Your 1991 does not have that temp sensor. You do not need to worry about that.

Here is what I did with my sensor:

Good luck!

OMG DO NOT DO THAT!
Hehehehe! I completely agree with you there!

I think he might have been talking about the air temp sensor.

The guy he talked to must have a newer P10 (94-96) G20.

With the hoes thats attached to the stock air box and a breather to it thats what I did if its the same. I have a 1992 G20, works with no problem.

But ask around first!
