S&M Autosport stainless steel and aluminum injector cups

[vwnut8392]

These are machined stainless steel injector cups for the AAN and 3B engines. These replace the crummy over priced plastic ones that we are always stuck buying and using. These are the prototypes which we will be testing here in the near future. We will also be creating billet aluminum versions that will just thread in and another version for welding into the intake. The black plastic one in the pictures is the only one i have ever managed to remove without completely destroying.

Nice work - these are pretty popular with the 1.8T crowd too. Our OEM cups have the same habit of cracking after a few too many heat cycles. Good to see an I5 option in the works

I'm looking to replace my injectors this year or possibly next year... once you have the final product I know I will be interested.

sweeeet

[Marc]

how much?

[ringbearer]

On fb around $100 for the set was mentioned

[Marc]

not bad at all. Kind of a pain in the butt part to make from a machining standpoint. I think its around $15 each for the plastic ones.

Thats right, i did quote in the one group on there around a 100.00 bucks for a set of 5. i figure if we all are going to get robbed 75.00 for 5 plastic pieces of crap we might as well spend 25.00 bucks more and get a metal one you never have to worry about again. The goal is affordable parts that provide longevity. some of the factory parts on the AAN are garbage in my opinon like the crappy powdered metal crank and cam gears that love to break on me. marc has that covered with the beautiful and durable tommis billet crank and cam gears.

also NLA metal thermostat housings...

machined thermostat housings is a pretty good idea! might have to look into that one.

The "T" coolant temp sender hose connection at the back of the block would sell too.

Are the AEB (1.8T) injector cups different from the AAN?

Also, why would people want to remove the plastic ones? Do they really crack and break all the time?
I do have some weird discoloration around the injectors on my AAN.

yes the 1.8T ones are different. i remove them because i wanted to clean and powder coat my intake manifold.

The OE plastic cooling system parts last at least 10 years. I don't see a market for metal ones unless you're able to offer them cheaper than new plastic ones (good luck)

The aluminum parts can be a pain in the ass as well, as they corrode and pit on the sealing surfaces over time and end up leaking.

I know the demand will be low and thats why we're making the parts to order. i personally feel once the metal cups are in there they shouldnt have to be removed ever again. if the aluminum cups would corrode and pit wouldnt the aluminum intake corrode and pit as well? i dont see the stainless corroding anytime soon too.

I was not talking about the injector cups, those are definitely worth your time. I was referring to the aluminum cooling system parts (thermostat housing since that is the only OE aluminum part).

searched quickly to find this photo - I've seen it much worse than this though. Granted, it is a 15 year old part, but the plastic ones last for a long time in my experience.

[vwnut8392]

ohh yeah! the old MK1 VW's had aluminum thermostat housings and they used to do that. we was thinking about stainless steel ones along with aluminum. i know the stanless ones would be probably be expensive but they would definitely be a buy it once and have it for life part.

by the way ed, my friend ryan contacted you about your silver S6 for sale on CL, did you get a buyer for it? i told him to jump on it because it was your car so i know it was very very well taken care of.

[EDIGREG]

yeah, he texted me last week but Taylor already bought the car

So you feel like a 3900lb weight has been lifted off your shoulders?

[vwnut8392]

i was hoping ryan bought it, oh well.

[vwnut8392]

well guys here's the aluminum versions! after crunching numbers i came up with a 130.00 shipped in the USA for a set of 5. i havnt had a chance to personally test them yet as i dont have new intake valves yet for the S4000. these will also fit a 16V intake manifold too after some test fitting so if you have an EFI converted 16V a set of 4 is a 100.00 shipped in the USA.

Very nice!
6061?
How fast does ethanol eat aluminum? Not an issue for me...

Their 7075 aluminum. ethanol doesnt eat aluminum, it will clean it though.

Another example of what happens to aluminum thermostat housings over time... try to get a hose to seal on this bitch!

it looks like we're backed in a corner with those things lol. the plastic ones break and the aluminum ones corrode. seems like the only solution is to make them from stainless steel.
