ok a friend of mine is a jack of all trades and he does metal casting. Im doing a t2 swap in my fb and talked to him about making a new T.B. adapter so i can run the fmic into it and not have the crappy stock angle to deal with. then i though others might be intreasted in this also. so heres my post, and a little describing . i figure 1 of 2 types being made. eather a straight out hose ...so it points to the fender/wheel and you would put a 45 or 90 hose on to this from your pipes or a hose aimed more towards the front of the car.
The only reason i even thought of this is i cant find anyplace that sells just the t.b. adapter. What would you be willing to pay? they would be cast alum. and then milled to the right size and such so they bolt right up to the stock t.b. and use the same size piping... and im sure he could make a few with large piping if people wanted them.

I'm definately not bursting tour bubble, homemade parts are cool, but check out this link:

I like the idea of the forward angle, maybe forward and up a little.

GReddy has finally started to offer them without requiring to buy the entire FMIC kit.  MSRP is $95.

higgi makes the staight nose out.. good price too if I remember.. one that goes towards the front of the car would be cool though

RETed

No link, but in their 2004 catalog it's listed as part number 12401000.

It must of been very recent that this was done. Due to the lack of the TB Adapter, at the time of trying to sort one out for myself, I said the heck with It. I'm going with the complete FMIC Kit.

So the boost has not caused any problems so far?

Can't see why it would, they are made out of a very strong plastic (nearly like fibreglass?).

Mine held up fine with boost and hasn't shown any signs of distress at all and I can't envisage it having any problems with boost in the forseeable future.

RETed argued this against someone before on here, saying he didn't the plastic piece could hols decent boost. I was unsure, and curious about it, so...

I bolted the stock NA TB with plastic elbow attached onto a piece of 1/4" sheet metal using some generic gasket material. I then grabbed PVC endcap I had laying around for another project and grabbed a silicone hpse connector I had kicking around the shop. I drilled the PVC to accept an air line fitting, and then used some worm gear clamps to clamp the pvc endpiece onto the NA fitting, attached the air pressure regulator, and started dialing up pressure, starting at 10psi.
At 16 psi, the PVC endcap popped out of the hose connector.... No bead on the endcap It scared the hell out of me, too.
So I sawed the last cm off of the endcap to give me a 1cm ring. Then I used a short length of PVC pipe that fit into the endcap, used PVC cement to attach it to the endpiece, and then left a 4cm gap and glued my little ring on, again with PVC cement. Basically, I made my own PVC bead to prevent the hose connector from popping off. It took some great effort then to get the hose connector over the bead, but once it was on and clamped, it was good to go.
I rehooked up the system, and started dialing up pressure again. At 30 psi, I got a little nervous, and stood a table up between the air regulator and my test system in cae the thing let go. I then continued dialing up the pressure to 65 psi, and figured that was enough. I heard a slight hiss at that level, which turned out to be a small leak between the TB and the plastic elbow. I could probably have gotten rid of that had I tightened the nuts on the TB.
I stood far away and hucked a couple bolts at the system too, to see if I could shatter the plastic at 65 psi with a shock. I nailed the thing a couple times, but it didn't let go. I was impressed and left it at that, and then remembered I had just destroyed a piece for my other project just for the sake of finding the end to an argument.


Coles Notes:
I tested the stock N/A plastic piece for boost. It held to 65 psi, more than I have ever seen a rotary run, making it a good enough piece for use in most non-bling applications.

Thanks for comfiriming my thoughts scathcart...
I mean it IS between 5mm and 10mm thick the whole way through it.... So I can't see why anyone would think it couldn't handle a good ammount of boost.

scathcart

Only problem I see is that they aren't pretty enough and that sharp edge on their corner (although it can be ground down effectively.)

SpeedFreak03

Thanks scathcart that will let me do a FMIC for a little cheaper now lol!

Kudos to scathcart for doing a test on the whole system!
The only thing I question is ignoring the temperature factor - even with large IC's, it is still possible to see intake temps at that point in the intake system over 100F.

If you're on a budget, I can it being an attractive option.&nbsp But, with metal options available (hIGGItrix for $120 shipped, and GReddy for $95 MSRP), it's no excuse to get cheap for those who can afford it.
