HKS FMIC...Routing the TID

I need to fabricate a TID for my FC. I just installed an old style Hks front mount. What are my options for making a TID?

Its just a generic 45 degree bend 3" intake pipe. I had to add a 3" or so section of 3" straight pipe to get the HKS intake to clear the FMIC piping.

The point is that all you need is a single 45 degree bend.

I found a lil filter and it fits perfect. . But yea, you just need a 45 degree bend. I found the polished aluminum one at pep boys for like 14.99.

Im glad I seen that pic for chaosseven. the Radiator hose sits really close to the two intake pipes. Wasnt sure if that was normal.

Hmm, In the first pic, I see that's an S5. On the second Pic, I see no MAF. I have an S4 with that huge chunky MAF.

the s4 maf has to be horrizontal, if its side ways or sitting at an angle it will not read correctly

blow by AFM setup
it is easier to route and the f-con doesnt care about it and would give correct mixtures

The F-con doesn't exactly care if there is an AFM or not. All the F-con needs is its own pressure sensor - you can see all 3 of my pressure sensors in my 2nd pic (stock, F-con, and AVC-R).

If the ecu is happy, the F-con is happy. For example, you can install the HKS VPC (now discontinued for FC) and you can remove the AFM. Usually though - the ecu requires the AFM.

I guess you can see by the orientation of my BOV that is what I had in mind. I just never got around to it. I did plumb it into a turkey call for a while but thats another story. Anyhoo, what I need is a 3" coupler on my TID with a small tee for the BOV.

At this time, the car runs fine and doesn't stumble except when letting off at light throttle. On hard accelleration, the rich condition at shift produces some spectaular flames.

My next project will plumb the BOV into the TID and the TID into the brake duct area where I will mount the filter.

2" from the turbo to the inlet and 2.5 inch from the outlet to the TB

I'm using the stock TID on my HKS FMIC. I was getting compressor surge and bucking at light throttle transition with the aftermarket BOV, this has happened to me several times before with other fmic/bov setups that utilized the stock afm.

So now I am running the stock TID/BOV to prevent the surge/bucking, and the HKS BOV because, well, it is already there on the piping and I can't remove it without hack-*** welding and re-powdercoating.

Ditto - someone was had welded a Greddy flange on mine and when I first put the BOV on it hit the hood! I had to hack-*** cut the pipe and rotate the BOV 180 degrees.

There was someone the other day selling an HKS piping kit for 60 bucks. I wish I could have picked it up just to get that pipe.

I was getting a lot of bucking at light throttle until I tightened the spring on the BOV.

Anyhoo - whats light throttle anyway?
