anyone still make fd uim adapters
Like the title says. Does anyone still make fd uim adapters? I saw a really nice one made from a place in Japan, but I can imagine it costs an arm and leg. I'm thinking of fabricating my own and just got a piece of 1" thick aluminum. Anyone have hood clearance problems with 1"
BTW, I saw mazdatrix selling fd throttle body spacers. I did a quick search and didn't get as much info as I was hoping. I am in the process of modifying and porting my s5 lim and fd uim and throttle body. Im going to start porting the parts and making the adapter |
i was thinking about it, i have the FD side drawn up, it just needs the FC side, and then i need to print a plastic one, and make sure it fits...
i was gong to have one with some injectors in it, i want to add fuel in a way i can remove when its time to smog the car |

But in ca there are so many regulations that anyone thinking of adding extra injectors and thinking about passing smog would need more than just the uim swapped to stock |
i think mine is 1" thick? its a pretty simple part, it could be done on a drill press if needed.
the HKS T51 was CARB approved... |
GP- you dont NEED an adapter, some porting and a tiny weld in one spot is all you need
|
I have a spare rising RPM one... but no hardware for it. PM me if you're interested.

I talked to my buddy that has a cnc shop and I am going to make my own cnc. There were going to be minor modifications to the fd uim( slotting the holes), I was going to use the s5 t2 bolt pattern to clamp everything down. |

I wonder if there is a plastic one that could hold the heat and seal. My throttle body spacer for my s4 t2 manifold is plastic.

old hot rod trick was to use a wooden and later plastic spacer under the carb and now they are using them under intake manifolds of SC motors to keep them cooler

or you could just buy some wood and a holesaw... its not the most complex part |
I dont have any data to back up the flow, but picking up the little bit of CFM from the throttle body and UIM more than makes up for anything from the lack of adapter.
Its not like the adapter transitioned the flow, all it basically did was extend it straight anyhow |

it works on a v8 because they gain plenum area, FC might be different
Even as a benefit for cooling im sure it only works for a short period of time before the spacer and whats bolted to both sides of it becomes the same temp |

I like to think if it were a proven benefit EVERYONE would be doing it.

If you make a tiny weld between the primarys then port match them (s5 to s6) you can make a MUCH smoother transition between the 2, that should flow better then the kind of angeled adapter, i did the weld, porting and then milled of the mating surfaces, cost me about 100 usd (i had a pro do the weld and the milling but did the port matching myselfe),

There is other stuff available for those that are interested. Here is a listing for insulation material used in the molding industry to keep the heat soak through the hot half down. Of course, it can't be printed and one would need to machine it. Press Platen Insulation |
