How far does mafs have to be from turbo? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

AndyCs13 · 08-24-2008, 01:13 PM

i need to get a piece of piping made to go from my turbo to my mafs, but i cant have it made yet. would there be a problem with using a coupling to connect my mafs to the turbo?

besides maybe the air filter not clearing the power steering pump? or would the turbo mess with the reading?

ooh and its a suck through mafs setup.

12 inches I hear is a very safe distance.

AndyCs13 · 08-24-2008, 06:36 PM

damn that sucks

timster · 08-24-2008, 07:03 PM

Eh it happens. It's not necessary to be that far, just safer. Go with what works. If you go closer and fry your MAF and suck little bits and pieces in to the turbo then you know you went too close. :|

Can anyone else verify the 12in theory?

Because my MAF is 12inches from the turbo and my car sometimes dies whenever it is revved up real high and let off the gas, which the only think I can think of is it being the MAF to close.

mine is about 12in away and it works fine.

running an SOHC maf

Mine is about 6-7" with a 45 deg elbow into the turbo and it's fine. The filter adapter on the MAF is much more critical than the distance to the turbo in my experience. Turbulence is bad up there.

i didnt think about it at first, but the heat from the manifold/turbine may be bad.

but i do have a couple extra mafs.

12 inches works ok but from what i here and have ben told it's "supposed" to be 18in away ???

AndyCs13 · 08-24-2008, 07:38 PM

Stock intake on a ka is well over 18" and the stock intake on an SR is about 18" if you were to straighten it all out and measure it ??? I could be wrong ???

AndyCs13 · 08-24-2008, 07:52 PM

actually it may be 18"

im just thinkin from memory

WoolyS14DET · 08-24-2008, 08:05 PM

Look at it this way just make sure that its over 12 in and it should work fine !!

AndyCs13 · 08-24-2008, 08:10 PM

easier said than done. im just trying to rig something up real quick because right now im running a stock mafs, but im going to be running a n62 mafs in the near future. so i dont want to spend a tone of money gettin one made for stock mafs.

Stock S13 SR intake tube is maybe 10-12" if you stretched it out.
