Dragonball Posted September 8, 2003 Share Posted September 8, 2003 If I may suggest - you really need to get hold of the Lexus 'adaptor' allowing you to simply fit the sensor in - rather than drilling etc It doesn't cost a fortune and will save you hours Check out search under oil pressure If you are in High Wycombe - give Mark Kindell a call about fitting etc - he's on the list Cheers Quote Link to comment Share on other sites More sharing options...
Terminator Posted September 8, 2003 Share Posted September 8, 2003 Paul where does the Lexus adaptor fit? Quote Link to comment Share on other sites More sharing options...
Supra ST Myster Posted September 8, 2003 Author Share Posted September 8, 2003 Here is a pic of what i have to fit just to see if thats what you think i have. It says on the side of it ... 1.Before installing the sender, make sure the opening has the same thread size 2 And check for oil leakes does that mean i would have to drill and then tap before screwing this in or is the a location already there somewhere with a block off or something??? cheers What is the Lexus thing?

SimonB Posted September 8, 2003 Share Posted September 8, 2003 You could buy a Greddy oil filter relocation kit, which consists of an adaptor that screws in where the oil filter currently is connected to a couple of pipes to another adaptor which you screw the filter into and bolt somewhere more convenient (like anywhere!). Both adaptors have 2 threaded holes for putting sensors in (one also has a larger threaded hole), which you blank off with a supplied bolt if you don't use. Then not only will you have an easy way of fitting your sensor, but you might actually be able to change the filter without taking half the car to bits or having four foot long bendy arms. I just bought one, and am putting oil pressure and temp sensors in. Haven't fitted it yet though. I think the Lexus jobby is the same idea, it screws between the oil filter and block and has threaded holes in for sensors (AFAIK). Quote Link to comment Share on other sites More sharing options...
SimonB Posted September 8, 2003 Share Posted September 8, 2003 Having looked at you piccy, your sensor looks a bit chunky. Not sure if it would fit using the Greddy thing - there's not all that much room around the hole. See attached pic. Quote Link to comment Share on other sites More sharing options...
Supra ST Myster Posted September 8, 2003 Author Share Posted September 8, 2003 hi thanks for the reply, my sender unit is approx 48mm in diametre, does that sound too big for the greddy thing? How much did you pay for it, where from? thanks Quote Link to comment Share on other sites More sharing options...
Dragonball Posted September 8, 2003 Share Posted September 8, 2003 From mkiv.com 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 Just make sure you tighten enough - or it seeps Quote Link to comment Share on other sites More sharing options...
