just gauging interset, I wasnt happy with the cheap **it on ebay, so I made my own, its billit aluminum, notice the air inlet is NOT in the center of the bolt pattern, this is why I beleive my part is superior, I know people make plenty of hp on those other pieces, but this is NOT generic, no slotted holes here, it is made for 240's by a 240 OWNER. Let me know what you think, I can post more pictures if you want. So far I have made them for SR's, ka24de's, and CA's, next up is q45.

Heres the SR-q45 adapter I made:

But billet would be much nicer cus I only had 3in tubing layin around so it causes a 1/2in reduction in flow just before the maf which probally causes some turbulance, but I haven't noticed any problems yet.

for my s13 KA i had a spectre adapter and it is close to what you described, the hole was in the center and hindered flow to the thermistor in the MAF. one day whlie cruising through the nissan section in my favorite junkyard there was a B13 with some spraypaint and wire loom, and the MAF adaptor had the inlet hole offset to the center. so it was straight through with the thermistor etc. It was a noticable difference b/w the two.

I just drilled out the one from the stock airbox. Easy and free.

Just a few suggestions.

Try adding an internal taper to the leading edge to smooth out air flow...right now your adapter has what looks like a 1/4" step between the ID of the filter or hose and the ID of your adapter. Also make sure that the ID of your adapter is the same as the ID of the MAF.

I will consider.

It is. Thank you for your suggestions, I will have to get some better pictures for you.

I think he was talkin to me. But I already stated that my design was inferior to yours due to the fact I used 3in tubing before the 3.5in maf.

Actually, I was talking to arg33...since he is trying to offer a superior product I thought I would add in some suggestions to make it even better. I was not putting your effort down any as you were making do with what you had and not offering it to others.

really nice matt..but, is this new? My MAFS adaptor is me hacking off the flange on the Z32 MAFS, and clamping my filter on to it http://forums.freshalloy.com/images/graemlins/smile.gif

I do have a huge ass 4'' Z32 adaptor if you wanna look at it for your Q45/Z32 adaptor.

No not new, I have been using my first one for at least a year now, dont know how much info I can get from the hacked z32 maf adapter, and after seeing how well yours worked out I wasnt so sure it would be neccessary.

HKS makes a nice MAF adapter for the Z32 MAF.

It's 4 inch inlet and smoothly reduce to 3 inch to mate with the MAF.

cost about $50 bucks.
