Problem with my turbo "Poor man's Type R" setup... "Subey" sound
To clarify, this is a B16A head, B18C block, and 9 psi of boost.
Well I got it started and the new motor was running fine for a while last night. I turned it off and started it back up. I rev'd it up a bit and put it in gear while it was on jack stands.
1st gear was good and moving. I put it in 2nd and I let the RPMS drop a bit and I got on it again and it got to about 4,500 rpms. I got on it a little more, 5,000 to be exact, and then I heard a pop. The car stumbled and shut off.
I went through and checked all the wiring, checked for leaks, checked for smoke... Nothing. I went through and checked all the electrical / ignition. I checked the new spark plugs. They were covered in gas, which was expected. The car is tuned for a full B16 setup, I now have it setup as a B16 head / B18 block and Edelbrock intake manifold and 70mm throttle body. Well I checked the plug wires. Nothing seemed off. But when I started the car again, it sounded like a Subaru WRX with exhaust.
For some reason I accidently touched the turbo manifold, and all of the runners coming from the block were hot as hell, which was expected, EXCEPT #4 I took out the spark plug and the wire. Turned the car off and saw a weak spark from the ignition for the #4 spark plug. I took out the next plug wire and put the plug into the wire and did the same thing. Same result, the plug set off a weak spark. I ran to the autopart store and bought a new set of plugs and new wires. Came home and installed them and I got the same results. Went back out today and bought a new dizzy cap and rotor and installed those and I'm getting the same results. The same "Subey" sound... Is it possible I have an injector stuck open or something. I can take out the plug and smell the gas in it.
I have no check engine lights, no bad sensors or anything.
Any help is appriciated.

My car sounded like a busted ass Subaru when I blew my piston ring lands due to a cheap turbo setup, poor tuning, and higher than norm C/R of 10.6.
Not sure if this is your case, due to a weak spark you discovered, but that "subie" sound may mean internal engine problems...

Hook up a vacuum gauge to manifold vacuum. Here are some links that might help you out.

I have a b20/vtec with the same issue. My vac. gauge rapidly bounces between 2-4Hg at idle. I think I have a bent valve or worn guide on the cylinder head even though I have 235psi across all 4cyls. Sucks cause I spent $$$ to have the cyl.head refreshed.
