came accross that


wondering if the "JDM" maf will be diff from ours and have some gains


anyone??

 

I think JDM means "cut wires on the connection"

otherwise, it looks to be the same, since all 3rd gens (VE or VG) have the same MAF.

 

JDM approved maybe?

ya thats what im thinking




JDM is stupid now, they just trying to sell something

 

When I ordered my JDM engine I was told to swap over all sensors as JDM and US spec sensors were not the same. Regretably cannot confirm and it doesn't make sense to me that Nissan would make sensors that are JDM versus US specific on the same car....not price effective IMO. You might be able to request the numbers off the MAF and compare to US sensor. If match, then I'd think they would interchange.

IMO: Do not buy JDM. Parts are run to death and mistreated. I recommend staying within the US....more specifically Maxima.org. I thought there was at least one MAF for sale in the 4 Sale forum. You could also search for a z31 MAF, same thing. You could go with a J30 MAF, but it has a different plug so you would have to cut your plug and sodor the J30 one in. Not worth the trouble.

 

The J30/Z32 MAF has the same plug as the VE/VG 3rd gen MAF. It's not the same MAF though. So unless you do other tuning, you can't use the MAF off a VG30DE motor.

I'm sure you can find a used VE/VG MAF for under $40. I had several laying around the house, but I slowly sold them over the years.

Darren, I believe streetzlegend has a VE MAF. I sold him one several months ago and it turned out he didn't need it. He will probably sell it to you for cheap if you PM him.

 

well... dont 240sx's (KA-t drivers) buy the MAF from the maximas? or the Z32

its probably the Z32 but my friend ordered one from a 3rd gen maxima... Aaron which is it since i know you browse the 240 sites

 

I don't browse the 240 sites. I don't know that one.

 

Yes, 3rd gen. max mafs or otherwise known as the N60 maf is becoming very popular with the 250-300hp crowd as that is about as high as they will support. You must do some ecu tuning to get it to work right. The z32 mafs (N62) are getting harder to come by and most of the ka/sr guys are not hitting 500hp anyways. (thats about what z32 maf will support)

BTW that maf is no different than our maf. same part #.

 

Yea the KA-T guys like them since they are much bigger inner diameter, the stock ones go down to about 2in. And the 3rdgen maf only supports about 30WHP more but flows better and is really common.

I was going to go KA-T on my 240 but Im dropping in a VQ30DE(TT) this winter so I know all about that stuff....

....we know. You let us know ANY chance.

 

Some sensors like a JDM coolant temp sensors or O2 sensors differ, but MAFs usually dont. Even if it did you dont gain from an MAF alone, youd need to tune the car to benefit. If youre not maxxing out your current MAF switching to a larger one does nothing.

 

winter is over and it still ain't even started

 

True, BUT:
Even though my current MAF housing was not maxing out, changed the housing to a larger one and really felt a part throttle and full throttle gains. Problem is, 3G MAF's are integrated ( cannot separate sensor from housing like A33's) so getting a larger housing and transplanting the sensor isn't really an option.

Any AFC/piggyback would work.

 

I pulled out the sensor in the 4th gen, its not hard but not easy like a 5th gen. You need to pry the top off, unsolder some connections and pull the innards out in 2 pieces. Jime transplanted his into a larger aluminum tube. Also there were a few Z32 aluminum tubes made to swap the sensors into. The 3rd and 4th gens are basically the same idea. http://www.sr20forum.com/showthread.php?t=142082

 

Nice info/pics!!



Here'e one of my many sensors housings




A33B though of course ( I know I know wrong forum )

 

Are you guys seeing any benefit to transferring the MAF sensor to a different housing?

Did Jime change his MAF sensor to a larger housing? If so, did he have to alter the fuel map?

I'm trying to figure out the benefit of doing this on the 3rd or 4th gen. Our housings aren't that small. Is there a potential for a HP increase? If there is, then I will get cracking on this immediately and conduct some dyno testing.

 

There have been several posts about this "mod." It's already been pretty much said, the MAF itself is not going to gain you anything. Placing the sensor in a larger tube is a "trick" some tuners use when building up their cars.

And I do retract prior information. J30/Z32 are same and not a plug and play for our cars. I had been looking for a z32 Maf when I upgraded to turbo on my max and the J30 popped up. Thank you for pointing out my mistake. Brain fart!
