Castro's M20 MAF conversion w/ chipped 173 dme

[KirkerBezerker]

Want more m20 POWER??? Well this is what you NEED!

I have a Castro brothers complete M20 Mass Airflow Sensor conversion kit, which is completely plug and play with adapter and chipped ecu.

I bought this kit off of MR 325, but never got around to installing it before I popped my motor. I plan to go 24v so I wont be using it.

So I just want what I paid for it, since its still sitting in the same box I got it in.

You get : 1 Bosch MAF, 1 Adapter, 1 "potato chipped" 173 ecu with MAF chip

$175 shipped

Ha, potato chip... What kind of gains should be expected?

[KirkerBezerker]

+50 HP guaranteed!!!

JK, just like all mods it depends on what it will be working in conjunction with. On a completely stock motor you can expect more throttle response, and some more power throughout the band. This allows for much more airflow than the little door on the AFM.

Best part is that you get rid of the huge, "barn door" style, dated, factory AFM.

interested. but why does the wiring looked so hacked?

[ghalee30]

any chance you can take a close up on the wiring adapter.. like the color of each wire

free bumps for life if you come throu haha

[KirkerBezerker]

Haha yea it does look hacked (probably why a picture of it wasnt included in original FS ad) but it just has some old tape on it. The one wire poking out has to be connected to the afms power wire.

I will take some up close pictures when I get home.
