Vacuum/boost line size of J-Pipe

[perley03]

Alright. My car is 90 miles away at a friends garage getting ready for paint. I bought a boost controller (Concept Illusions) a while back but never put it on. Well the nipples on the boost controller are 1/4 and I looked at the lines coming off the J-Pipe and the wastegate actuator and they were smaller, but i never measured them. I was wondering if any of you know the stock size of these lines for a 90 GS-T with a 14b so i can get the right nipples at Autozone. Thanks guys.

If you use larger line it will help the turbo spool a little faster and dont use to much line. Just bring the mbc to autozone and just match it up to some vacuum line

I'm not asking what size line I need, I'm asking what size line comes off the J pipe and goes to the stock BCS so i can buy the right size nipples to put on my MBC.

ANYONE???? Nobody knows the size of the stock vaccum line coming off the J pipe?? This is pathetic.....i guess i'll either buy 1/8" or 3/16" ### i know its definatly not 1/4".

Why dont you bring the LINE to autozone, and match it up with the nipples. I know there small nipples. I just don't know the size, and yes its def not 1/4.

Because the car is 90 miles away at a friends garage getting painted. I can only go up there on the weekends because of my work schedule, and this weekend is the weekend im going up. He works 60-70hrs a week and is never home during the week so i cant call him and ask.
