Your best bet would be to get the Greddy oil filter relocation kit. I know it's more money.... Changing your oil is much cleaner and it provides 4 different places to screw the oil pressure sensor into. Joe at Altered had plenty in stock a couple weeks ago, when I bought mine. Just be carefull with o-rings that come with the kit...I ripped one by accident and I'm having a hell of a time finding the right size to replace it.

Install...

Is there anyway to install it w/o the oil filter relocation kit? The instructions say to remove factory oil sensor and then to install the greddy one in place.. If I install it this way do I just leave the factory oil sensor unplugged?

Oil Pressure Sensor Mod for 93-96 only

Factory Oil pressure sensor and warning method is not exactly the greatest for those of us with modified engines. I've been looking for a way to keep the redundancy of having the factory sensor in place with it's warning but also wanted to run a oil pressure gauge. Here is what I found to be the best way of doing it.

If you ever tried to access the factory oil pressure sensor, you'll know how difficult it is to get to it. Instead of removing it just use the Union bolt from the new 2001 Lexus IS300 (picture below). This will allow you to add a second oil pressure sensor for your pressure gauge easily.

The Lexus IS300 run the factory pressure sensor on the base of the union bolt which is much easier to access than the Supra pressure sensor which it screwed into the block behind the AC compressor.

Simply remove the stock union bolt and replace it with the Lexus unit. Once tighten to recommended torque, screw in the aftermarket oil pressure sensor to the base of the union bolt. Make sure to use some Teflon tape on the new pressure sensor to keep it from developing any leaks. The whole job will take less than 1/2 hour and now you have two devices that will worn you of impending disaster should the oil pressure drop to dangerous levels.

The part number you need are,

90401-19008 Union Bolt
90430-20016 Gasket
90301-68005 O-ring
Lexus IS300 Setup




Supra 93-98 Setup

Emptoyparts...

Thanks for the information. Any idea of what these extra parts will run in? I don't understand why Toyota got rid of the oil pressure gauge? The MKIII had it along with a boost gauge and the MKIV doesn't?:( Oh well. Thanks again.

You can also get them thru ANY local Toyota dealer:smile:

They might not have them in stock but you should be able to get them in a day or two.
