Just wondering if a 2.25 silicon coupler can forced to fit on a 2" pipe and a 2.5"? Yes, i understand its not the "proper" way of doing things, but does anyone have any experience with this?

 

I wouldn't do it personally, too much of a chance of it breaking or leaking.

 

Duct tape.


Oh, JB Weld too.

Man thats 1/4" difference all around, just get the proper coupler.

 

$20 is much cheaper than a tow truck, that's how I see it anyway.

 

you are better off rigging something up with rubber ABS couplers and an ABS reducer than what you are talking about

 

Needs more 2-2.5" reducer?

 

Carry that pipe to the muffler shop. They can inlarge or shrink the pipe that much. Probaly free to $5.00 for their time. Then you have a matching size.

 

Check out siliconeintakes.com They sell all the different couplers for cheap. You'll be pissed if you blow a coupler or tear one. Plus it could cause you to over-spin and damage your turbo. And who likes half-assing ****? I mean, if you're in a bind, sure. But don't rig it to save 20 bucks.

 

No.

 

I got a 2 inch coupler to fit a 2.25 inch pipe, just make a small slit in the coupler at the end to help slideing it onto the pipe, use some hairspray, and force that sucker on there. Its been holding with a v band clamp for 8 months now...

 

you can put a piece of 2" hose around a pipe and then slip a 2.5" coupler over that, then clamp it down. but I doubt you'll get a silicone coupler to stretch out to be bigger.

 

Microwave it in a bowl of warm water. It works, but its ghetto.

 

word, get the silicone warm and you can get it to fit a .25 inch larger pipe than intended.

 

Still thinking about it.

 

Another question, Whats wrong with using a regular rubber hose to connect 2 metal pipes together? Technically, there is no room for it collapse. Im reading that these silicon hoses are good for 100+ psi, why would i even need that much?

 

OEM turbos use rubber hose. You don't tend to see silicon from the factory. It works.
Advance has some exhaust pipe reducers in various sizes for a couple bucks each. It's a cheaper way to reduce pipe size than a silicon reducer.

 

Rubber gets weak at high temps. So when you're boosting, the hotside charge pipes get really hot. And plain rubber will fail at these temps. Hence why silicone is used. It can take the heat.

For crying out loud, just buy a 20 dollar whatever you need and be done.

 

I'd recommend looking through the car parts store's radiator hoses to find what you need. It's intended for moderately high temp, moderate pressure, and is cord reinforced. I've been using a 2" 90° bend from this method since May with a few thousand miles on the clock and it is in perfect shape. If you look closely at my sig pic, you'll see it coming off the compressor outlet.

 

Im a cheap SOB that wants to make a a 135 degree bend as cheap as possible.

 

I'm gonna laugh at you when your $6.35 solution fails you and damages your slightly more expensive turbo.
