RB25DE/DET MAF differences?

[ossy]

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?

Pink & green labels have different wiring.  They are otherwise equivalent.

See this page for a partial guide http://www.paulr33.com/diagrams/airflow-meter-wiring.html

So what colour is the standard one on a spec 1 non turbo R33?

Also are non turbo and turbo ones the same?

I'm looking for the answer on this too guys. Does any one know?

Also is this the correct maf and does it need re-wiring?

Any help would be much appreciated.

That's the pink sticker type, you haven't said what car so no idea if it's correct, 25de or det is the same in the same model.

25de in c33 a31 is different to r32/r33 s1 which is different to r33 s2 & r34 so you can vaguely do whatever man.
