Im about to pull the trigger on the diy intake. I have conflicting posts. Should I get 4" aluminum tubing (will this clear the belts/radiator etc) or 3.5" tubing. Please let me know. Thanks. Hows this parts list look
https://order.store.yahoo.com/cgi-b...8c8aea883d2&l=&s=_.52Jq0qGFQ9KbS2bR3hmP3NvSY-

Plus I would need a 4"-3.5 reducer and Im good right? Just need a final word on whether or not 4" is too big or will it clear the radiator/belts. And also will the 4" elbow fit snuggly around the tb? Thanks

Stock stuff is around 3.75 OD. The 3.5 will work fine it, but won't be the easiest thing in the world to get onto the TB. Plus you won't have to worry at all about the clearance.

I used 3.75 silicone hose for the whole thing I just have to couple it in one spot, but I covered that with a 4 inch pipe clamp.

Oops, I meant that I had 3.5 inch hose.

I am current waiting for a Silcone reducer elbow.

Have you seen this thread?

This is the thread I found and I plan to order everything and try it as well.

This is what I'm trying to do.

4" to 3.5" silicone reducer elbow (Due sometime next week)
3.5" aluminum tube
#.5" silicone Hump hose
1x 4" clamp
2x 3.5" clamp
K&N Air filter (drop in replacement)

If you order from Stealthwork expect it to take at least 3 weeks to get to you. They are located in San Francisco and I am in San jose (about 60 miles away) and it has already been 2.5 weks and I still don't have it yet.

Got sick of waiting so I ordered another from a company in Washington and should have it by Wednesday along with the one from Stealthwork.

I will take some pic's and post when it's done and I could have any extra reducer elbow if anyone is interested.

Yea their prices are a rip off. I found all the parts for less than half of stealthworks prices.... Y would you goto a smaller tube size 3.75(stock) to 3.5???

Will 4" Clear, Thats All I Need To Know. Thanks

 

[CTSV_Rob]

Agreed but the company I ordered most of the parts from (boostcontrollers.com I think) did not carry this reducer elbow. The quality of the stuff from boost controllers was really good.

Not sure if the 4" will clear. If I had to guess I would say no because it looks like the 3.5" tube will hit the radiator fan support. then again if your creative enough you should be able to get it to fit.

I wasn't too concerned about 3.5" vs. 4" because the MAF is 3.5" so even if you put the larger tube in you will still be retricted to 3.5". The minor gains you may get for the 4" tube may not be worth it.

It would probably look cool to have that huge pipe in there. Let me know which way you decide to go.

Once I have it installed it (hopefully this Weds) can give you some numbers and pictures. Can you wait this long?

why did you have to use a coupler? was the hose just to short?

4" will fit but it's tight. Use a couple of tie-wraps or something similar to pull the tube tight against the radiator else it will end up in the pulleys. Once installed, check it often to make sure it isn't touching the pulleys or belt.

 

[JonCR96Z]

Yeah, hose I used was a 90 degree bend with 10 inch legs, it was just a little bit too short so i had to cut it up and couple it together so that it would reach and look good.

You really don't need any bigger than the 3.5. Its not gonna help unless maybe you have a 90mm TB. Even then the restriction from the airbox wouldn't allow it to flow its full potential. If you'll look at the 75mm throttle blade itself you'll see how small it is in comparison to the 3.5.

Elbow came in last night, I fit everything up and will be cutting the Aluminum 3.5" tube today.

Stealthworks is a pain to deal with, Expensive but the quality of the elbow is good.

have you ordered your parts yet?

I already told ya, IT FITS...it's just tight.
