I plan to up the boost soon and I decided to checkout the condition of my reducers/hoses. About half of them were cracking although none had cracked all the way through yet.

I replaced all the blue hoses and reducers that connected the piping for the Greddy turbo kit. I purchased the new ones from http://www.hightempsilicone.com/ , the total bill was around $150.

I've only had my kit 7 months and there was noticeable wear/tear on the reducers/hoses. The worm clamps bit into the silicone and there were cracks on a few, even on the inside. The new clamps I used are T-clamps and do not bite into the silicone like worm clamps.

Looks nice! Can you post the shopping list? I guess you had to buy them separately.

Yeah, looks great!

 

I'll get the shopping list together and post.

The reducer on the pipe going down from the throttle body was alittle too big. I believe they were out of the correct size on all colors (2.5 to 3). I got 2.75 to 3 and made it work.

 

Interesting find. Did you contact Benny to get his opinion?

I wasn't impressed with the kit hoses to begin with and used silicone ones from HoseTechniques instead. Nice to know I made the right choice.

No, I didn't talk to Benny.
I read a thread where the puerto rico member's reducer split open when he increased the boost (10psi?). So I decided to check mine out.

 

good info, adrian-1. look forward to seeing the shopping list when you get the chance. thanks.

Adrian,

you're new hoses looks great..................................

the reducers that came with the greddy kit are not top notch.

Diagram of couplers/reducers below. The numbers in parenthesis would fit better than the ones I got.

If you want to replace the 3 hoses on the air intake , you'll have to measure those yourself. I didn't replace those since they're not pressurized. Also, I relocated my filter behind the bumper using the websites intercooler 12" hose.

 

How did you clamp the intercooler hose to the intake filter? And is that a 3" or 3.25" ID?

The intercooler piping is 3" ID and 12" long (I had to trim 1 inch off).
To connect the two, I used a 3" (76mm) hose joiner found here.

 

This is a highly recommended mod for the stock greddy kit.

Mine also burst: http://proxy.searchirc.com/turbo/brokencoupler2.jpg

I tried to order from HTS, but they are out of transition hoses. I ended up going with MazworxRaceSupply.com (Located in Orlando).

Plus all the t-clamps came up to a total of $130 including shipping.

Edit: I replaced all hoses and all clamps, including clamps on the intake. So I spent around 200.

 

are the clamps needed or....?

 

the t-bolts are better. mostly because they don't eat into the couplers (see pics above)

In case you were wondering... I decided to replace everything including the vacuum hoses and came across this.

Vacuum hose reliabilty test (scientific experiment): Viton vs. Neoprene vs. Silicone (thanks TracyRX7)

http://www.geocities.com/MotorCity/G...5/hosetest.pdf

 

Viton tubes ... where can I get those ?

 

you can get it here:

http://hightempsilicone.com/category/vacuumhoseviton/

They cost about 5x more than silicone hoses...

I wouldn't bother. The vacuum hoses aren't in locations where it gets really hot.

I did buy pure silicone hoses (red), cost me about $50. It looks great.

 

anyone who needs coupler..... HTS seems to be out of stock on a few hoses... i googled and found this place.... http://www.extremepsi.com/store/cust...me.php?cat=772

found it a bit cheaper (few cents off most hoses) but there is at 7.50 handling fee, no biggie got everything + 14 clamps for 126

 

i just recieve my hoses today from extremepsi, shipping was fast!

hoses look kinda small... from what i last remember the piping was bigger? i hope these are the right sizes... we'll see tomorrow...
