How To: Boost leak tester for $5.02
#63
I am in the process of doing this myself. I bought everything at Menards ( a regional Lowes type store). The reason for this is you can make it in less than one hour and be ready to go. There is no curing time for any epoxy or gasket sealer. The auto stores in my area also have zero parts llike this on hand. You have to wait at least a day for it to ship from their big warehouse.
I used:
2" flexible coupler (just 2"x 2" coupler for PVC, metal jacketed ones won't work)
this will also come with 2 band clamps so you won't have to buy extras
2" male threaded cap (I tried the rounded 2" cap that fits over the pipe but I just couldn't get it to fit)
1/4 NPT air hose nipple
1/4 NPT coupler ( right next to nipple usually) to screw on the back
teflon tape
I used a vice to hold the threaded male cap, drilled out a pilot hole and then used the drill and bit to ream out the hole to the appropriate size. I didn't have the appropriate size drill bit so that's why I had to ream it out with the drill bit like you would with a zip saw. I made the hole tight enough that I could start the nipple in the top of the cap and still have enough material to make threads. Essentially you are using the threads on the nipple as a tap to the cap. I backed the nipple out put 2 loops on teflon tape on and tightened it down very snugly. I put the 1/4 NPT coupler and tightened that down. I put 6 or 7 loops of teflon tape on near end of the 2" threaded plug and then slipped it into one end of the coupler and tightened it up. The other 2" side goes directly on the turbo inlet, and then tighten it up as well.
The turbo inlet is really close to 2.5 " but the inside diameter of the 2" coupler is very close to 2.5".
I went to 30+ psi and it held fast. I found out I had a throttlebody leak and wil be fixing that soon.
