OK today i got bored and I was like lets go make a tid mod. THe first one is made out of PVC pipe and it is 3in the whole way. Now im working on a 2in madrul bent pipe tid mod. I have pics of the PVC pipe one. I would be glad to make one for any one on the forum. I was think 55 for the PVC pipe one and 75 for the mandrul bent pipe.

 

Parts needed:
2 - 3in 45 degree BLACK pvc pipe elbows.
1 - 3in to 2in plastic reducer.
1 - pcv pipe glues
1 - a nipple barb.
1- drill
1 - thefflon tape
1 - couple to go from the top of tid to MAF.
1 - peaceof metal braket, i used the ones with many holes in it.

1. place the 3in - 2in reduc on one elbow.
2. connect the reducer to your turbo.
3. take the otehr elbow and drill a hole in if and tap your ipple barb into it, and use pcv pipe glue, or silcone cocking to seal thenipple in place soo noair gets out.
4. take some pcv pipe glue and rub in on the insde of the first elbow, then connect the 2nd elbow to the first and find the angle at which you have to turn it to go around the airpump if you have one.
5.connect the MAF to the tid and then hook up your vac lien to the nipple.

 

Isn't there more than one vac line going into the stock TID?

 

no there is one vac lina nd one hole for the stock bov, thats on an 87 -88 89 and up have 2 vac lines

 

So what do you do with the bov line?

 

doesn't the reducer that goes to the turbo have to be silicone, I read that in another write up

 

Ya or rubber. It looks rubber in the pic he posted.

 

though that reducer is a good thing to keep and eye on, I had a rubber one and the heat from the turbo cause a hole to form under the hose clamp....caused my idle to be screwy just inspect it everytime you remove it..I'm still using the rubber because thats all they had at home depot...could we just go to a muffler shop and get them to bend a pipe for us...where can you get the silicon hose connectors?

 

I went and bought a reducer from the home depot, it looked just like that and on the lable it said it wasn't intended for high temperatures or something like that so I didn't use that. Im still trying to find somewhere to buy a silicone replacement though. someone suggested a parts store for big rigs or someplace similar.

 

Here you can buy the silicone couplings.

yea the reducers i use are rubber, and they are from heating pipes, they use withstahd the heat. I just finished the prototype of the pipe one, it will have silcone connects if you order one from me.

 

Why not make a 3" mandrel bent one?

 

I can make a 3in mandrul bent pipe one for about 95. all prices include shipping

 

the black stuff is NOT PVC, its ABS! DO NOT USE PVC! IT WILL MELT!
after using PVC and realizing how crappy it was, i went to an exhaust shop and got a 3" 45 degree mandrel bent exhaust peice. and i used silicon couplers. works perfectly, and looks a million times better.

 

the pvc i got form my dad who is senior estmator at romanoff mechcanical. and he said the black pipe i got is for high tmemp water, i also have 3 in madrul bent and did the same thing, i just dont have a pic of it yet.

 

exactly what I did, except I used 2.5'' piping to try and keep down the boost creep. I ended up getting the pipe for free, exhuast shops have stuff like that just laying around :shrug: I need to find silicon connectors...I'm still using the home depot rubber connectors

 

black is ABS, white is PVC... the front side of the turbo is not not, the rubber is fine.

 

The black stuff you have is probably used for solar heating. Thats the stuff I use with my work. It holds up just about the same as the white stuff. It just holds heat alot better to keep the water temps high.
