RB25DE/DET MAF differences?

Hi, are there any differences between the MAFs on non turbo and turbo skylines (RB25DE VS RB25DET)??? I suspect the MAF is knackered on my non turbo R33. Also what's difference between the green and pink labelled ones? I've tried searching but can't find much info and a straight answer.

 

I recently brought the car and it has some major performance issues. I know non turbos are slow but mine is ridicilous. Honestly, it feels like it's got 80bhp max and that a 1liter Toyota Yaris would easily beat it lol. I've also been in a stock 2liter RB20e R33 with an exhaust and even that was twice as fast... It was parked up for a while so I serviced the car, changed oil, oil/fuel filter and sparkplugs. It gained alot of power but not as good as it should be. It had a broken cone filter fitted so I replaced it with a stock airbox+ filter but the car has lost power again but saw that the MAF was broken and the top has been taped up to hold it together. I pulled some of the tape off earlier so suspect that may be the cause and since then, it idles abit rough sometimes aswell but a little tap to bring to revs up sorts it out.

Also the car has massive 3.5" straight though exhaust which I'm sure it's making me lose a huge amount of power. Am I right in believing that the ideal size should be 2.25 or 2.5" or wouldn't the exhaust make much difference?

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.

      Hi All, putting the engine back together and everything is perfect except have this plug left over.. any ideas what it is for and where it goes? Is on cold side under the intake plenum *note not a stock plug, as everything has been modified Cheers
