i just got my 240 and would like to say I love it and have been a big nissan fan for 6 years i have worked on freinds 300zx's i have worked on maximas and sentras but now it is time to take all that knowledge and put it into my car. First off i found my car from my manager at big-o tires where i work. it is an 89 and it only has 40,000 original miles on it and i got it for 4,500 dollars. so any way i started dinking around with it and i took the fan off replaced all of the vaccum lines painted the valve cover and was looking at the maf sensor thinking that there had to be something i could do to make it bigger or something, and i remembered i had a n/a 00zx maf that is 3 inches wide it doesn't mount straight to the car but it was something to start with. I took my maf out of the metal housing and tried to see if it would fit in that one, i had to rip al of the electrical out of the 300z maf and grind down all of the edges i also took the 4 bolt holes off of the end of it so it was round then i took a rubber o ring and put it over the round sensor on the maf and stuck it through the hole for the 300z's i found two self tapping screws that would fit through the holes on the sensor and screwed them into the plastic then i sealed all off the bottom and sides with silicone then i drilled a hole in the bottom of the maf and put the intake air temp sensor inline there. Then i had to sand down the stock box "for now until i get a k&n for it" to mfit the maf through once i got it through i put the metal ring thing back on and tightened down the bolts it seems to run fine but it is still in testing i am trying something i saw on here about a 330 ohm resistor tells the computer that the intake is 42 degrees and with the bigger air hole i am thinking it should level them both out. I am going to do a full write up on how i did this with pictureslet me know what you think it might be possible if enough people were interested for me to make more of these for a reasonable price

Ok from you’re story you took a Z32 MAF housing and put in a KA stock “hotwire” MAF sensor so now you are pulling in way more air than you sensor can ever read. Running it this way is going to max out you’re MAF and send you’re injectors to 100% duty cycle. This is not the way to do man! I’m not even sure this will run correctly. Next time just use the whole Z32 MAF including sensor because it is more capable of reading more air. Make the change at the ECU.

IT WOULD NOT PLUG INTO THE STOCK Z32 MAF HOW WOULD I DO THIS. THE CAR DOES RUN FINE AND ACTUALLY HAS WAY BETTER TOP END
