I installed the Greddy Turbo Kit and 3 months later i have experienced pressure leakage since than.
I trade a few hoses that got cut but it keeps happening. The hoses that came in the greddy kit are low quality.
Now i want to trade all the hoses for better quality. Someone can tell me the specs (sizes and shape) or send me pics... anything that helps me to make the hoses without dismonting the car?

I know i have to dismount the car to trade the hoses but i want to have the new ones done before do it, so the car can be less time in the shop.

I don't know if i made myself clear, my english is not very good. Anything you can question me.

Thanks

 

I would like to know the sizes aswell so i can upgrade the clamps and connectors to better quality

 

I changed myne out to high temp silicone couplers a while ago. Much better stuff. I also changed to their Tbolt clamps. Not sure if I'd recommend them though. I had 2 break on me. Do a search, the sizes you need have already been posted.

You may also want the shop to leak check your system. Thread here. It could be one of your small vacuum lines has a small tear and air is escaping through there.
