one more question to you synolimit. I am going to do this and my current intake/maf housing is like your txs (aluminum and 66mm). I am maxing out my volts though and needed to get a bigger housing on my intake. since I plan to run my car without an intake once I do a draw through I assume I would still need to get a bigger maf housing when it's on my intercooler piping. I'd still be maxing out my volts whether it be a draw through or blow through system right?
I couldn't find much on that kstect and bt page. but I have a whole rotated set up and wanted to go with a blow through maf before I retune. need a retune since I'm maxing my volts last time I tuned. I was thinking rather than using the bigger maf housing as a draw through go blow through. it's approximately 76mm or in other words 3 inches. I'm only wanting to push upper 200awhp since my tranny and engine probably couldn't handle more in the 04 wrx.
alright thanks for all the input. I was asking my tuner about it and he was saying I should just stick with a draw through set up, although I would prefer the blow throw set up but I'll follow my tuners advice.
Little late on this reply but you can buy a 3" aluminum housing from spectre . Or autozone. They have mandrel bent tube as well so you can sell you cai instead of cuting it up. Buy the maf housing for 30 ish and a new pipe with a 90 deg bend on it for 40 ish. Say you have a 250 $ cai, sell it spend a 100 of the money and to get new parts . You come out with 100 in your pocket . The 3" part number is 9405. It comes with inside adaptors incase your tuned for smaller housing size.
