75mm MAF to 92/92 FAST

Tomorrow I am installing my FAST 92/92. The problem I have is connecting a stock size 75mm MAF to a giant 92mm Throttle body!!! what can I use to fit that mis matched 75mm maf to 92mm Throttle body?

I know what you thinking...buy a 92MM LID and larger MAF and solve my problem. Well hollidays are here and money is tight so I am currently going with the stock size LID and MAF.

what the heck can I buy to connect the stock size MAF to a FAST 92/92?

P.S. Will a Smooth bellow connect to a stock size maf and to a Fast 92 Throttle body or do I need a larger MAF for the smooth bellow and not as large Throttle body? AHHHH please help!

are you sure about that? 92mm converts to 3.6" and thats I.D. not O.D.

OP go measure the O.D. of both then you'll know what size you need.

I think you have to measure the actual OD of the hardware in question. For example, the OD of the 78mm throttle body used on an LS6 is the same as the OD of the 90mm throttle body used on an LS2. (I know this because I did a swamp and was able to use the same intake tube.)

The stock accordion style connector will fit over a 90mm TB with a little stretching. I'll bet it would stretch over the 92 as well to get you going anyway.
