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

I'm on my cell phone so I don't seed where you are from. 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...

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.

Btw, I'm thinking about making a throttle body spacer also. Anyone ever dyno it before? My only concern is clearance to mc.

it works on a v8 because they gain plenum area, FC might be different

Well one guy on the forum and did a dyno, his peak hp number didn't change much, but torque and hp high mid range was significantly better with little to no drop in power across the powerband. Adding a throttle body spacer would increase plenum volume without purchasing a custom fabricated manifold. The best example i could think of its the 350z. That is my reasoning, but I guess nobody ever dyno ed before and after. If you could put a price on hp and torque per dollar spent on modifications, how much do you spend per hp?

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.
