Was going to go to home depot and get some supplies for an intake and turbo master. Was wondering how big in diameter the tubing should be and what type of material?

black pvc. either 4" or 3.5. I don't recall which one. Aluminum would be better if you find it somehow.
And use a torch if your going to bend the home depot full thread. it breaks when you bend it. Been there done that.

is that actually a safe website?

it's a 3.5" inlet to the turbo.

is that actually a safe website?

I'm not sure what you mean by that?

I think he means if it is secure for buying off of, and all the credit card info you provide and such is confidential, or something along those lines.
I think the call it VERISIGN

is that actually a safe website?

Yep. It has a Geotrust seal, but great question... If in doubt, use the phone.

Oh, I see. I wouldn't be able to give you the info that the above posters did, but I can tell you I have ordered from them in the past with no problems. I've mentioned this company numerous times over the years. Do a search and you'll find quite a lot of posts about custom intakes. Everything has pretty much already been talked about.
