ok, heres the situtation. TID cracked on the turbo side, tried epoxy but fitting still loose, losing vacuum from 20mmHg to ~18mmHg (Idle) but otherwise the car runs fine....sometimes idles rough until car warms up (maybe until the TID has softened abit.

heres the plan, unlike most ppl on here that replace everything with a 45* bend intake i want to keep the stock PVC TID and just replace the cracked side of the duct. planning to mount a silicone coupler between the turbo and the brittle plastic.... 60mm(2.5 inch??) on the turbo side and not sure about the plastic side...please enlighten me....thx

 

been looking at some couplers on ebay sized 2.5 to 2.5...would it work?....

 

Why do you want to keep the stock TID? Besides being a restriction, the entire duct is prone to cracking. Mine had cracks near the bov and crankcase breather inlets, as well at the bottom.

Also, I doubt you could get a good seal between the coupler and the duct, its not smooth and its too weak to be able to clamp down hard on.

Though if you want to fix the one you have, I had a little bit of luck sealing the leaks with electrical tape, it worked for a couple weeks until the tape dried out and came off, maybe you can just epoxy over it?

 

clamping a coupler to the TID? no go son.... as soon as you put any pressure on that brittle, heat fatigued plastic... itll crack and break.

ever see the plastic connectors on engine harness connectors on Z32's and MK3 supras? the heat generated fatigues the plastic so much that they lose ALL plasticity and have no pliability.. the clips break off as soon as you push them down to pull the conn off. the TID will have the same issues.

 

i bought a intake from 2a+ron but it didnt have the stock bov bung and i dont feel like weldin anything.....why is the 7 such a strange car?....

 

You dont necessarily need to weld, the intake duct isn't under any real pressure.

Go to Home Depot and buy the right size nipple for the bov return. Drill out the right size hole on the intake you bought and just epoxy it in. As long as you make sure its air tight, it'll work fine.

Or if you like shooting flames, you could just vent the bov to atmosphere...

 

yes shooting flames would be nice.....but not really needed......thanks...i'll look into it

 

A cracked TID shouldnt affect your idle that drastically. It would just allow some unfiltered air into your intake system.

 

it does.....before it would idle between 500~900....around 500 if i dont gas engine dies after some epoxy it was better

 

Ugh, I am a dumbass... Thats what I get for answering posts when I wake up. Yea, it affects the amount of air the AFM sees.. Duh..

 

lol you posted at 12:41.

Waking up at the crack of noon are ya?

 

i fixed mine with duct tape. it was also cracked on the bottom near the turbo

question: is the turbo size 2" or 2.5. i cant seem to find any 2.5 couplings.

 

good ole ebay
