Question Alky Injection nozzle on 2.5" FMIC pipe.

I have a FMIC and SMC water/alky injection kit. I need to mount the nozzle in the 2.5" pipe. I was sent 2 of the metal washers with rubber pads. The rubber is 1/16" thick. Have you, that have done the same installation, had zero-leak success without having to create a flat spot prior to drilling a hole for the nozzle?

I used everything that came with the SMC kit, but also used a bunch of jb-weld to seal everything up good on the outside of the IC tube. It never leaked, and chipping the jb-weld off to swap the nozzle wasn't bad (I started with an M5 and moved up to an M15). Whether or not the jb-weld was needed is another story, but it was easy and gave me peace of mind.

Thanks for your input.


Oops, I just realized that this is in the wrong forum. It should be in Water/Methanol Injection, Nitrous & Intercooler Cooling. Mods, please move it.

I had a PITA time getting mine sealed. Steve from SMC told me that it does NOT need to be flat. I drilled my 25/64 hole, and tightened the living ishf out of mine. It turnes out...it needed tightened more. During pressure testing, it leaked. tightened a smidge more...and it quit. That metal washer, with the rubber on it, does not want to conform to the inside of the tube. If it was bent a little more like the intercooler piping, it would be sweet. I would advise you to put some sort of sealer around the outside after you tighten it down, just like the other guy did. i am going to do that too.

I am running the m15 nozzle on a gt30r.82 kit also.

M5? M15? How do you know? My nozzle has only two things engraved on it, MW7 and HAGO. Was there supposed to be more than one nozzle in the kit?

Did you use a washer inside and out or just inside?

Then your nozzle is the m7 I believe.

I only used a washer on the inside of the pipe.

The SMC kit only comes with one nozzle. I think you can get different nozzles direct from SMC, but I ordered mine from www.mcmaster.com the part number for the M15 nozzle is 3178K77 and if you search for it you'll get the part numbers for all the other nozzles.

And now that I think about it, mine might have had an M7 or MW7 in it when I bought it.

It wasn't spraying enough With a gt35r and high boost I needed more flow. On a stock turbo the stock nozzle should be fine. I bought an M10 and M15, started with the M15, and saw no reason to even bother with the M10.

You are gonna want the m15 nozzle.

the m7 isn't going to flow enough. However, it really depends on what you do with the system. Do you want the system purely for safety, or for power? pick one.


If you want power, go with the m15. You are going to need more volume. I have the same turbo setup too. m15 + SMC = FTW
