ok im getting together everything i need for my summer turbo build.i want to make sure everyone thinks im doing it the right way and using the right stuff.its a STOCK b16a in a 93 hatch w/garrett gt-17 turbo and dsm smic.im making my own mani, is 1.5" piping good for that?and i was also thinking like 2.5" for the DP since im only running like 5-6psi while the motor is stock.what about charge piping?should i stay the same on both sides or switch?either way, im not sure on what size would accomodate good for my mild setup.thanks

 

i would not go below 2' for any charge pipe set up on any turbo kit

 

ok,i was just wondering bc i have infact done some research, and ive seen people use 2 dif sizes on each side and wanted some suggestions on that, as well as what size downpipe i should go with bc i was thinking 3in just might be overkill for a low boosted stock b16 idk.as far as the 1.5" for the mani goes, i think thats ok....what do you guys think about the other two tho?

 

no one can help me out with what size piping?wtf...

 

What the ---- are you talking about?


Use 2 inch or larger piping for charge pipes and the biggest possible for your downpipe, you want the least restriction possible, 3 inches is not overkill.

 

ok thats what i needed to be told.now,how can i determine whether to use 2in or say 2.5in for charge pipes, i dont want to just say enie meanie miney mo

 

use 2.5, its got good top end

 

ok thank you
