Chris88 Posted May 10, 2014 Share Posted May 10, 2014 I'm just sorting out my NA-T and will be using a Mocal thermostatic sandwich plate for the oil coooler take-off. I also plan to use a 'standard' sandwich plate for the feed to the turbo and the oil pressure sensor. Which plate should be closest to the block and therefore closest to the pump because as I see it there are pros and cons to both ways around. With the turbo feed closer to the pump it will see the higher pressure but always the hotter oil, whereas with the Mocal plate closer to the pump the turbo will be fed at a slightly lower pressure but once the Mocal bypass is closed it will receive the cooled oil. Which way is best, or is there an issue which makes it not a good idea? Quote Link to comment Share on other sites More sharing options...
Al Massey Posted May 10, 2014 Share Posted May 10, 2014 Room may be an issue with two plates and an oil filter. I've not been a fan of sandwich plates after I had a slight oil leak on my old NA. Have you thought about the Lexus bolt mod? Quote Link to comment Share on other sites More sharing options...
Ian. Posted May 10, 2014 Share Posted May 10, 2014 I used 2 plates on my 350Z, never had any issues with it & wouldn't have an issue doing it again I had the thermo plate furthest away from the pan Quote Link to comment Share on other sites More sharing options...
Suprakeith Posted May 10, 2014 Share Posted May 10, 2014 My mate has two sandwich plates on his s14 and he hasn't had any issues at all, he also got the thromostat one furthest away Quote Link to comment Share on other sites More sharing options...
Whitesupra95 Posted May 10, 2014 Share Posted May 10, 2014 I've used 2 sandwich plates on my Nissan for 5years with out an issue. Just don't over tighten the shaft in the middle Quote Link to comment Share on other sites More sharing options...
Chris88 Posted May 10, 2014 Author Share Posted May 10, 2014 Thanks guys. I'll make sure that there's enough space (don't know the thickness of the Mocal sandwich yet) and if they fit with the filter I think I'll go with the turbo take-off nearest to the pump.

Chris Wilson Posted May 10, 2014 Share Posted May 10, 2014 2 sandwich plates are a mess, not a good idea at all, the fewer potential leakage point in the oil system the better. I would take the turbo feed and oil pressure from a drilled and tapped stock oil filter mount assembly through bolt. I can supply a modded one, exchange, or you can buy the expensive Lexus one from Toyota. Use a T piece to split the hose to the turbo and feed the oil gauge off the T. -4 Goodridge type hose is fine to the turbo. -3 to the gauge.
