After searching the board for several days and doing all the research i could i'm come to a wall...
At the end of april I bought a TE-44 from PTE (which took FOREVER to get, but thats another story.)
Now after finally getting what I paid for and everything else that went wrong back together I have this problem:
WOT in any gear I get 8 psi, at a stop trying to build boost the best that comes is 1-2 psi, from a stop or a roll it spools insanely slow.
all the above kind of made me believe the puck in the stock elbow, wasn't sealing correctly. since it appears from what I read that the wastegate hole in most TE-44s are ported. I checked this problem after triple checking the Y hose going to the wastegate actuator was on correctly. After looking at the carbon ring on the puck and on the turbo its self it looks to me that its sealing. The line appears a little thin on the turbo, maybe its still a problem, hard for me to tell. I'll see about getting some pictures see if anyone else can judge.
After that I put the elbow back on and double checked to make sure it was bolted down nice and tight (not too tight that it would strip the housing)
Now I figured since everything above seemed to check out, that may I had an exhaust leak. So I had my brother look around the engine while I tried to build some boost, since it was pointless for me to try and look at it at idle. That turned up nothing.
Next I checked the intercooler and all of its connections. That turned up nothing either.
So out of ideas, I decided to put the stock oil blowing turbo back on to see if it acts the same way as the new turbo (since the car has been sitting since late april till a week or two ago.) Did some testing tonight, and it performs just like it did before I dumped a lot of money on the PTE TE-44.
The turbolink logs from the tests with both turbos show about the same data, just one with a peak of 8 psi.
The car sits mostly stock except, accufab FPR, green stripe injectors (30lb hr ones), 160 degree thermostat, the motor was rebuilt sometime before I came to be the new owner. So all I know about that from what i've seen/read:
None stock timing gear/chain. and the best I can make out on one of the receipts is something about TRW pistons that cost $675 or so. Not sure on the fuel pump so I have a racetronix hotwire kit with 340m sitting in the trunk with a few other goodies i'm waiting on installing till I solve this problem.
Sorry for the whole life story thing (at least thats how it feels to me). i'm at a loss, so I figure every little bit helps.
Maybe someone, can point out something I forgot to check or something else I can check. I hate this feeling of not being able to fix my own car, or feeling of hate for a car that won't let me fix it.
Thanks for any help.
