No power

[1blackteg]

I just put my motor back in yesterday and started the break-in last night all was going well untill about 15 min. ago when all of a sudden the engine just isn't responding. It won't produce any boost, when you rev it it like it just sits there and hits a wall like an early rev-limiter almost..... it won't come out of vacume. I've already changed the plugs, checked all vacume hoses, looked around for Major boost leaks (don't have a tester so can't accually test), and checked the turbo. I'm only on about 8psi right now for the break-in. There is my mod list:

6 bolt motor:
Crower Rods
Wiseco .40 over pistons
NEW crankshaft
mitsu metal headgasket
Built head

I would say your rich from tuning or boost leak, but you said your always in vacuum; and rich would cause an increase in boost pressure, and if you had a boost leak big enough to hold at vacuum constatly, you should be able to find it by eye.
How's your electrical situation? Maybe it was just a loose connection from install that worked it's way loose; that sounds logical, since you said the car stopped running so good after about 15 mins or so.
If I were you, I'd just double check all the electrical connections; keep us updated, and good luck.

sounds like a vacume line came off to me. i would definialtly do a boost leak test.
