maf and ARC induction query

[fitch9014]

What is the stock sizing of the ca18det maf? What is the stock sizing for the sr20det (s13) maf? I have the air intake blues and would like to find a nice filter to feed my monstrous stock turbo. I have an ARC induction box that's supposed to be for a ca18 but it doesn't fit. So, I measured it, screw hole to screw hole is 70mm. I thought I'd read somewhere that the ca maf was 70mm, but when I tried to bolt it up it comes up just short. So, I thought I'd ask to see if anyone knows what's up. I would like to know if it might be for another car so I mighten could seel it. Thank yer, fellas.

couldnt you just measure your ca mafs? 65mm sounds more like an sr mafs, not 70. Did you get the induction box for the sr what? not sure about the ca one though.

i got it from eBay for a ca18det, but that's a crapshoot. i'll give it a try (the measuring). but i thought if someone might have had a similar problem...
