Im new to this and i was planning on making a compound setup using a 62mm s300 turbo over ht3b but not sure what size i should get the ht3b in and also not sure how the pipes run or where to get them pleaseeeee helpppp!!

 

The twins I'm running, I forget the top turbo....I know its an s300, think its a 52/57/.08, or somewhere close, and the bottom is an ht3b at 71/74/26. It spools quick, not a lot of lag. the turbos and piping are pdrs towing kit.

 

Where did you get the piping

 

I didn't buy the kit, my buddy did, but he bought the whole setup from Piers PDR. I've just helped him out with the build, before we traded trucks.

 

I bought all mine from a local heavy duty parts shop. 3" and 5" exhaust elbows, 45's and 90's.

 

Ok thanks guys excited to get this build started
