as you all know I'm turboing my 5th gen vq30de-k. I was going to make a custom inside diameter maf housing and use my factory maf sensor but all the aluminum pipe that I'm finding is 3 inch outside diameter and 2 7/8 inside diameter.

can I use a 300zx (z32) maf sensor on my 5th gen? if so does anyone have a wiring diagram?

Also is there any specific year or model I need to get the maf sensor from?

Do I need a twin turbo 300zx maf?

I didn't check your build thread to see if you are going to run an emanage, but I was going to say just keep stock maf and use the MAP also.

 

Just use the Landrover MAF.

You just swap your Sensor into the LR MAF housing. Its like 82mm i believe.

 

alright I got a 300zx maf pigtail and maf adapter all I need now is a write up on how to install the 300zx maf in a 5th gen

 

Check JWT webpage they may have it or call monday and talk to Ben. If anyone knows it will be them!

 

hopefully this can shed some light at the end of the tunnel. i found this thread in a local maxima forum!

FYI 300ZX twin turbo and non-turbo MAF sensors are the same..

 

I have both a 300zx TT MAF and non-turbo MAF at home. The pins are different (one has 5 pins and the other has 4 pins), and the pig tail wiring colors are different.

There are no turbo specific meters - they are the same. They even have the same part number 22680-30P00.

 

Im also looking into this, some said the z32 maf won't workk with a stock 5th gen ECU....is this true. I have a VAFCII........

 

Then how do you explain the physical differences I described here???
I'm pretty sure I read in one of absoundlab's posts that he determined that a Z32 MAF couldn't be used. Hopefully he'll chime in here.

 

It be interesting to see how much the stock sensor can support in THAT housing.

 

IIRC one has a extra ground and they do have the same flow propertys!

 

didnt seem to find anyone mentioning inner diameter on the 300zx tt/j30 MAF. i read the rover is 82mm but that wont do me any good on my 4th gen. answers appreciated. thanks guys

EDIT.. i found the z32 maf is 72mm. same as oem 4th gen diameter

 

I have a Q45 maf. Its fairly large.

 

a q45 maf wont work in a 5th gen

 

Well you guys dont have many choices then man.

 

so is the 300zx maf the only option for us 4th gens?

 

I've got something in the making right now for all you 5th gen owners out there.

 

^Happy to be a test dummy

 

you aren't the test dummy I am lol and its a part that really doesn't need to me tested

 

NO no. I have a q45 maf on my 4th gen man and it works fine. Im barely tapping it.

 

LRMAF housing will increase the potential for the 5th gen sensor.

 

^ YES........you are right, hopefully it will help me idle a little smoother too

 

Odds are it won, LRMAF makes idle quite lean. At least in my experience.

 

the fix for the 5th gen's will be released soon

 

ok. . . . .

im assuming u have a tune with this as well? how was the improvement. also are you n/a? or fi. thanks

 

Turbo'd and yes i tune with a safcII for now.

 

custom 3" maf housing

 

Interesting, though I'm staying NA.

Why use reducing couplers? Why not make the entire tract 3"ID?

 

^ charge pipe is smaller, the other coupler is a 3in to 3in coupling, its just stretched over the pipe thats why the other side looks smaller. I only know this because I bought one of these from absoundlab before he got banned.
