A while ago i upgraded to the 60mm throttle body with the spacer for my 77 280z and now i finally got the Toyota Supra air flow meter, which is 74mm, to put in. I'm stoaked! anyways, now the origanal boots that connect the TB to the intake manifold and the AFM are way too small. anyone out there done this app. before or just have any idea's or anything? thank you

 

get silicone reducer couplers the appropriate size and band clamps and some metal piping and make up your own sparkly new intake.

 

awesome! thats what those stupid things are called...silicone reducer couplers. sounds pretty dumb, but i couldn't figure out what the actual name was for those kind of tubing until now! thanks so much

 

Why not upgrade to the L28ET AFM & swap the N/A guts into it? Then you have a larger AFM that is still calibrated for your ecu. Do you know if the Supra AFM is calibrated for the same air flow & injector sizes as the L28?

 

yeah, with the Supra AFM you've got to change out the circut card and the circut card connector with the 280z one and then it will connect right up with the ECU and read it the same. the Supra and 280z systems were pretty similiar. the Supra AFM is the largest i've found (74mm dia. mouth) and the flap is MUCH lighter than the 280z. i am also running Supra injectors right now which are almost the same injectors as stock 280z but bigger. anyways, here's the link:
