blown turbo or motor? searched
b20 hatch with drag kit t3t4 /w hondata s200 basemap.. the hatch has been down for 6 months.. getting painted and getting a turbo kit added on.. well i finished last week, everything started up fine, i barely drove it.. but with the hondata basemap that st00pid in houston burned for me.. at around 3.5k motor stutters, probably from too much fuel from the rich basemap.. but it drive fine besides that, under 3.5k it ran fine.. so i took it in for inspection, early this week.. failed because of an exhaust leak.. so i left it there over night for them to reweld my exhaust and downpipe to fix it.. so when i picked it up.. it drove like ****.. when i drive it back to my shop and turned it off.. i didn't want to turn back on.. it cranks but doesn't start.. i popped the hood and noticed oil where my downpipe and turbo meets.. my oil pressure was at 80psi before i turned it off (thats why i dont think my motor is blown).. i dont get a CEL or Oil light.. could it be the turbo? do i just have to rebuild it? i haven't took the turbo apart yet because i didn't have time..
Cliffnotes: oil visible where downpipe and turbo meets, oil pressure was at 80 psi before i turned off the car.. no CEL or Oil light.. car cranks but doesn't turn on..

How did the car idle before you turned it off? Was it "different" than before. I blew 2 of my cylinders (rings/ringlands more than likely) and the car still idles but barely. The exhaust sound was popping more than it did before.
Do a compression test on it. Drop a new set of plugs in while you're at it. You might have fouled the plugs out with that rich setting. Well, fouled out might not be the right term.
Mine didn't wan't to start anymore either and I put a new set of NGK BKR7E's in there and it fired right up. Blown motor and all.
(had to drive the car to the port to get it shipped off this island).
Anyway, compression test, new plugs. Let us know what you find.
My money is on shot rings. The exhaust guy probably took your car out and beat the **** out of it and blew it up.

Those are NOT good. A decent shape motor should get in the 185+ neighborhood. With those numbers you posted you're getting a lot of blowby, getting a lot of smoke out the tailpipe and your oil probably has a really strong gasoline smell to it when you do an oil change. I would say it's time for a rebuild.

Re: (Tanmt)
you need more than tuning. with compression numbers that low. im willing to bet you washed out the rings or something. Do not drive that car until you figure out the source of your problem

Yea, the numbers match up nicely, but tooo low.
Try doing the test on WOT.... Let us know.

B&M = kinda crappy. Aeromotive = adjustable up AND down.
I made the switch and love it. The Aeromotive isn't THAT expensive either.

Eh, it's good enough to use, but you can't adjust your fuel pressure below what the stock unit is set at. This sucks if you're running an aftermarket pump, because you can't adjust your fuel pressure below like 50psi unless you drill the hole like shown on the Endyn site. This is the reason I went with an Aeromotive.

tried lookin at your plugs... i ran open dp with a rich basemap and it was fine til i got my exhaust on... half way home it sounded like a boxer motor, slow as hell too. i figured since i got my exhaust on my boost is prolly lower and im running a bit more rich.
pulled my plugs, cleaned them off then started it again. idles and ran smooth again

I think the coarse area is normal...like where the rings don't reach the top of the cylinder.
