Making a boost leak tester

[Blu90GST]

Making a boost leak tester because today while doing a compression test I found that I'm running rich (plugs were black up into the threads) I'm hoping this is because of boost leaks even though my motor is due for a rebuild (90ish psi on cylinder 2). My main question in asking this is what size hose do I need to make a BLT for my 14b? And also does anyone have any suggestions on a budget rebuild kit?

Don't really need a hose, just use the same flexible adapter that connects intake to turbo. Only instead of an intake, plug the opening with a PVC cap with an air hose adapter and a pressure gauge in it.

if you decide not to build your own try This is the default title by turboboostleaktesters.com
and they have good info on how to do one and why its important.

I've read that. Yesterday my car took a crap on me (won't idle and dies coming to stop lights) it seems to pull a lot harder now though... I don't know why, I'm lost on this. I've set base timing and my BISS screw grounding the corresponding plugs for both and still nothing. I'm also 99% sure I'm burning oil so looks like it's time for a rebuild. I'm ordering all new internal hardware from ARP Tuesday, right now I'm looking for a decent (and cheap) gasket set an bearing, along with pistons. Using an AISIN water pump I found or 45$ also. Any suggeations?

maybe do a compression test and a leak down test

I did compression and my results were mostly decent except cyl 3 which was at 90 psi. Do you have any suggestions on some budget bearings good for around 400hp?

I made this boost leak tester.

I would do a set of ITM Piston Rings and Main/Rod Bearings, I have actually used them in a 6-Bolt before and they are doing great.

I think I'm getting new pistons from NPR. I'll look into itm bearings though

And I saw that post before but I can find any couplers to go around the 2" inlet and the PVC cap I bought

The itms have are for around "350ish horsepower" I would rather spend more for the peace of mind of knowing I'm not going to spin a bearing on my backup motor.

I am not sure what size the 14b inlet is but what i did to make my tester, was use the coupler that attaches my intake pipe to the turbo and put the pvc cap in that. worked like a charm for me.
