Guest joeyhammer Posted November 13, 2002 Share Posted November 13, 2002 ive got a friend with a junk 300zx.. i think its an 84.. maybe with an 86 engine.. can i use his mass airflow sensor and throttle body with his computer? is it a hard swap to do? should i grab anyhting else that will benefit my zxt swap into my 240.. i havent done it yet.. how about the fuel pump.. will and 84 pump work with a 83 turbo? thanks guys Quote Link to comment Share on other sites More sharing options...
fl327 Posted November 13, 2002 Share Posted November 13, 2002 computer has to modified to work with l28et maf wont work with stock computer without mods as well. i would take coil ignition transistor throttle cable fuel pump and more stuff im sure, but id have to be there.

SleeperZ Posted November 14, 2002 Share Posted November 14, 2002 I use the Z31 computer and MAF in my 280ZT, with a modified 280ZXT harness. If you want to avoid wiring hassles, just use the Z31 wiring harness. The Z31 pump is an in-tank model, and I don't believe it flows any better than the stock ZXT pump. I am using a used Bosch pump I've modified that flows 50% more fuel at 60 psi, and I can sell you one for $60 shipped. You can also adapt the throttle body without much trouble - just cut the shaft short and rethread it for the Z hardware, use the Z31 TPS and a 1/2" spacer and it bolts right up.

Sean73 Posted November 20, 2002 Share Posted November 20, 2002 Nathan, I've collected most of the parts I need for the Z31 MAF conversion for L28ET, but there are a couple of unknowns still. This is what I have so far: 1)ECU 2)distributor trigger disk 3)MAF 4) O2 sensor 5) throttle body and TPS Which air regulator do I use - 280ZXT or Z31? What about the water temperature sensor? Are there any 300ZXT specific sensors that I need to be concerned with. Thanks - Sean Quote Link to comment Share on other sites More sharing options...

I am using all the stock 280ZXT sensors, except the fuel temperature sensor, which is probably the same for all the VG applications. I am not using a knock sensor, and I'm not sure if the '82 knock sensor will work or not. A new one from a Z31 is too expensive to play with in case it's the noisy '82 engine giving me the computer error and not a bad knock sensor.

Brad-ManQ45 Posted November 21, 2002 Share Posted November 21, 2002 I wonder if the knock sensor will work w/the P90A head? It sure is a lot quieter... Quote Link to comment Share on other sites More sharing options...
