little num Posted March 22, 2009 Share Posted March 22, 2009 (edited) well not sure how diffrant the vvti is but i fitted my pressure sensor into the lexus mod bolt, basically its the same bolt as you have already but its drilled and tapped to add another sender (your new 1) i will try and find some info for you.

little num Posted March 22, 2009 Share Posted March 22, 2009 Oil Pressure Sensor Mod for 93-97 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) OR from a 1998tt Supra. This will allow you to add a second oil pressure sensor for your pressure gauge easily. The Lexus IS300 & 1998 Supra 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 (65 pounds), 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 warn 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 (Optional) Supra 1998 / 2001 Lexus IS300 Setup Quote Link to comment Share on other sites More sharing options...

bignum Posted March 23, 2009 Share Posted March 23, 2009 You could use a sandwich plate for your oil temperature or a sump plug adapter and i think theres a t-piece available for the pressure sender to go in your existing bolt, or you could put the pressure sender in the plate aswell but the reading is normally high.
