MD355 Posted July 10, 2020 Author Report Share Posted July 10, 2020 Ideally I would want all 3 gauges green.. The two gauges that are missing lamp inside, have red filter inside, so when you illuminate them, they show red dials... If I put green LED in those gauges, what do you think will happen to the dials ? will they show slightly green, or red ? Thanks! Quote Link to comment Share on other sites More sharing options...
andyblackman777 Posted July 10, 2020 Report Share Posted July 10, 2020 Did you get to solve the problem of no oil pressure? Quote Link to comment Share on other sites More sharing options...
MD355 Posted July 10, 2020 Author Report Share Posted July 10, 2020 @andyblackman777 faulty oil pressure sender... Replaced it with a new one.. No longer problem I also installed 2 more senders for oil pressure for gauge and oil temp sender for gauge.. plus turbo boost gauge.. plus no more oil leaks My car will be super soon !! All I got to do now is figure oil the color of the backlight of the new gauges Quote Link to comment Share on other sites More sharing options...

sailorbob Posted July 10, 2020 Report Share Posted July 10, 2020 What are the make and model number of the two gauges with the red backlight lenses? Quote Link to comment Share on other sites More sharing options...
MD355 Posted July 11, 2020 Author Report Share Posted July 11, 2020 The are the original OEM Lotus gauges : https://www.sjsportscars.com/parts-and-accessories/A082N4036F.htm https://www.sjsportscars.com/parts-and-accessories/A082N4035F.htm They are missing the light inside But when you use a flashlight to check the instrument, the dials are red... The third gauge OEM Lotus is already green : https://www.sjsportscars.com/parts-and-accessories/A082N6067F.htm (it is from older pre 1995 Esprit, whereas the other 2 gauges are from 1995-1998 V8 esprit.) All I need to do is figure a way to make the red gauges show green... Not sure if a green light will do the trick, as the facia of those 2 gauges is red...

sailorbob Posted July 11, 2020 Report Share Posted July 11, 2020 The pre '95 A082N6061F oil pressure gauge, A082N6067F oil temperature gauge and B082N6060F boost gauge are all listed as having orange illumination but use the A082N6070F green sleeve so maybe the sleeve an option for you.

MD355 Posted July 11, 2020 Author Report Share Posted July 11, 2020 I will try to use green light to see what the 2 red gauges show.. If I knew that, I would have ordered all 3 from the same era/model, even though I think the turbo and oil pressure from the old model are obsolete..

MD355 Posted July 14, 2020 Author Report Share Posted July 14, 2020 (edited) Urgent help need : So today we started installing the gauges The Oil Temp gauge was straight forward The Esprit V8 (1998) Turbo boost gauge has 3 connections behind labelled 1,2,3 and the turbo boost sender unit has 2 connections (can someone help me in explaining to the electrician how to install it ?) The same applies with Esprit V8 (1998) Oil Pressure Gauge , 3 connections behind labelled 1,2,3 and just 2 connections on the sender unit. Please help ? Thanks Edited July 14, 2020 by MD355 Quote Link to comment Share on other sites More sharing options...
ekwan Posted July 14, 2020 Report Share Posted July 14, 2020 (edited) If they are Smiths/Caerbont gauges then the 3 connections go to sensor, ground and +10V.

I dismantled the gauges on mine, cracked the red lenses with a pair of pliers, then installed the bulbs with the green “condom” that I mentioned previously.

MD355 Posted July 14, 2020 Author Report Share Posted July 14, 2020 (edited) @ekwan you are too brave... I will simply make these three gauges red.. As for the turbo boost, do you have any idea why the turbo boost sensor has 2 connections behind ? what is each connection ? Thanks !!

sailorbob Posted July 14, 2020 Report Share Posted July 14, 2020 On the boost pressure sensor one connection is to the boost pressure gauge and the other one is to GND. Usually pressure sensor connections are marked to suit this. 1 Quote Link to comment Share on other sites More sharing options...

MD355 Posted July 20, 2020 Author Report Share Posted July 20, 2020 (edited) Today’s update : So today all sensors and gauges were installed and tested.. While the oil temperature gauge worked perfectly, the oil pressure gauge behaves strangely. At idle it shows around 1.5 bar and at 2500 rpm around 2.5 bar. The reaction time of this gauge is kinda slow. Is that normal ? The part numbers are For the sender : A082N4038F For the gauge : A082N4035F Edited July 20, 2020 by MD355 Quote Link to comment Share on other sites More sharing options...
MD355 Posted August 26, 2020 Author Report Share Posted August 26, 2020 Update : It's been a while and I wanted to update you on my car. All three gauges are installed and work perfectly. I placed them under the stereo right in front of the gear lever. They look amazing. Left is turbo, middle oil pressure, right it oil temp. The oil pressure is usually around 3,5-4 bar When hot and idling it falls to 2,5 bar which I think is fine. The oil temp takes about 10-12 mins to get to 60 degrees C. The turbo gauge, the most I saw is 0,5-0,6 bar in 4th / 5th gear above 4000rpm at full throttle. I am beginning to think the aftermarket BOV blow off valves might be leaking air... Should I remove them ? Opinions ? Quote Link to comment Share on other sites More sharing options...
mike_sekinger Posted August 26, 2020 Report Share Posted August 26, 2020 I would check that your wastegate actuator base setting is maintained correctly. If that solves your peak boost, then you could still decide to remove the BOVs. The turbos are very small, running moderate boost and have very little noticeable lag.

mike_sekinger Posted August 26, 2020 Report Share Posted August 26, 2020 Service Notes - section ED page 41. You'll need a dial gauge and pressure source (hand pump) - check for rod movement of 0.4mm with 0.34-0.36 bar (4.9-5.2 psi) 1 Quote 1996 Esprit V8, 1998 Esprit V8 GT, 1999 Esprit S350 #002 (Esprit GT1 replica project), 1996 Esprit V8 GT1 (chassis 114-001), 1992 Lotus Omega (927E), 1999 Esprit V8SE, 1999 Esprit S350 #032, 1995 Esprit S4s, 1999 Esprit V8 GT (ex-5th Gear project), 1999 Esprit V8SE ('02 rear) 1999 S350 #002 Esprit GT1 replica Link to comment Share on other sites More sharing options...
andyblackman777 Posted August 26, 2020 Report Share Posted August 26, 2020 Is 0.6 bar about right for a stock set up. I thought the boost was limited somewhat in 1st, 2nd and 3rd gear to protect the gearbox. Quote Link to comment Share on other sites More sharing options...
MD355 Posted August 26, 2020 Author Report Share Posted August 26, 2020 (edited) @andyblackman777 yes this is true !! In fact I checked with 4th and 5th gear... The ambient air in my area was rather hot even at night... Around 27 degrees C... So I guess at winter I should see maximum boost of 0.75 P.S. My car is running decat straight pipes and sports air filter... Edited August 26, 2020 by MD355 Quote Link to comment Share on other sites More sharing options...
MD355 Posted September 14, 2020 Author Report Share Posted September 14, 2020 I finished the installation of the turbo boost, oil pressure and oil temperature gauges.. They are very useful and easy to see.. I chose to put the most important, oil pressure, in the middle so both driver and passenger can see it.. The red color looks cool with the heater switch above that is also red.. What do you guys think? 2 Quote Link to comment Share on other sites More sharing options...
MD355 Posted October 7, 2020 Author Report Share Posted October 7, 2020 Update : Almost disaster today !! Hi to all ! Today as I was driving at low speed I saw that the oil temperature gauge was showing zero and I could hear a noise like pulling metal cans on a string behind the car.. I pulled over and saw that the adapter my mechanic had custom made and connected with special metallic hose was hanging under my car.. See photo.. If the connection broke, I would lose all oil with dramatic consequences.. I immediated loaded the car and too it to my mechanic.. We saw that due to stress related to vibrations from the engine, the thick metal plate connecting it to the sump of the engine broke off !! We placed the adapter on the chassis with clamps and used rubber too for vibrations.. Quote Link to comment Share on other sites More sharing options...
