I was just going to order a starter set from Hose Techniques to get me started doing most of the hoses under the hood. Things like BOV hose, boost gauge hose, hoses for my boost control valve and other misc. hoses you visually see. I am not going to attack the hoses under the manifold yet but I will soon. I was told to get 3.5mm thick walled ones. So anyways, what would you say would be the best 2 sizes to focus on, 6mm and 3.5mm or 4mm?? Just wondering what you guys thought, thanks. Also what length of hose should I get of each to just get me started doing the minor things, thanks,

Oh and does anyone know off hand the size of the stock couplers on the IC and Y-Pipe plumbing?

You have to pay for shipping each time you order which is like $8. Just get it all at once, it's like 8ft free.

Get alot of 3.5mm (40-50ft) and probably about 10 feet of 6mm (20ft if you have a profec). Running a boost gauge and profec will take up atleast 10ft of 3.5.

Y-pipe couplers are 2.75" if I remember correctly, I posted it before, you can search.

 

Thats a good point on the shipping. So you dont think I would need any 4mm at all, just use 3.5 and 6 for everything?

The 4mm really isn't needed but I did get some just incase. If you want you can substitute some 3.5 for 4mm, it will still work on all solinoids, just that the 3.5 fits snugger.
