hey guys can anyone recommend a good air flow meter upgrade fo the ca18det i have heard z32 is good does it bolt straight up, connector ? and also does it work on standard motor dont wanna buy a/f computer just yet if i can get it to run good without touching stocky computer i wanna try until i can afford it

There is no bolt on and go AFM upgrade as far as I know. If it bolted on and worked then it wouldn't be an upgrade because it would still be limited to the same maximum flow.

SR20 is a minor upgrade but probably not worth the bother. RB20 is reasonable, I think they are rated to 300hp or so. Z32 is what you want rated up to 500hp. I think there are some nissan V8 ones that also might work.

None of these are physical bolt ons either.

Why do you want to upgrade? have you upgraded the turbo and injectors as well?

i have a bb t28 on custom manifold and 3 inch exhaust and front mount i will be upgrading the injectors once the engine is running. does the z32 have the same electrical clip?

z32 is the go. But you will need to chip the ECU (See www.PLMS.com.au) - Pete's a nice guy, and his products are great.


Z32 MAFM has a different clip, and different colour wires, but the wiring diagrams for them are all over the net.

If you are sticking with the factory computer..you are best to ask Pete what combination he already has maps for.

thanks addtodude you never fail to com,e up with the right info. thanks
