Ok guys, I am having a little problem, right now I have no way to source parts, pull the old motor, and get it all together in the short amount of time when I am in the USA. I am a contractor for the Govt, and I am in Iraq.
I just bought my GN in April of this year, 89,000 miles on it, supposedly rebuilt 10,000 miles before I bought it, 200/200 lunati cam, stock heads, possibly ported, Power plate, TE44 turbo, Dutweiler intercooler, 42lbs injectors, older pitbull chip, Turbonetics wastegate, etc etc. First startup and I hear some lifter tap, nothing serious and goes away pretty much when warmed up. I drove it around for a little while to warm it up, smacked to throttle and buried a 20psi boost gauge in it. Engine is breaking up, and sputtering. Pulled foot off throttle and went to normal cruising speed. Adjusted manual boost controller down to 15-17 psi, Car is boosting well, still having sputtering and hesitation at times. I plug in my scan tool and find the following
Throttle position .45 v
spark advance is 36°
Mass air flow is 4 g/s
Idle air control is 61
coolant is 200°
BLM enable is NO
Block Learn is 150
Integrator is 139
Closed Loop
Knock Signal NO
I get a check engine light showing lean, and sorry I did not capture to O2 reading when I took the picture I am writing this information off of.
I replaced plugs, wires, and O2 sensor because the reading was almost stable, with little change when driving.
I had to leave to come back to Iraq, and my father took the car to a storage space. While driving he tells me that he heard a loud bang, sounds like one of the lifters collapsed or something happened, because it is clacking bad, and it stalled. He restarted and had to restart 5x in the 8 miles he drove it to storage. So up until today I had no idea what had happened, My daughter and my father went out to storage today to skype me while they tried to figure out what happened to it. In the process all the intercooler pipes were checked, thinking maybe I got lucky, he had a boost spike and blew a hose off... Nope, all tight and no visible damage on top... So I tell my daugter to look for oil underneath the car... what ever was left in the oil pan after the drive is now on the storage floor covering a 3ft diameter circle... My father attempts to start the car and the sound is more like 400 midgets with hammers in the motor, versus a collapsed lifter, or bent push rod, and with the oil on the floor, it is very apparent that parts of the motor are not where they should be.
So that is the story of what happened, wish I was telling you I was up against some exotic, or racing another member, but sadly, she was on a slow drive with a 68 yrs old man when she sighed her last breath.
So now comes my question, of you guys here on the forums building engines for customers, I am looking to put together something in the mid to low 10 second power range, from a proven builder with that reputation. I am not asking for safe, and keep it together, nor am I looking for cheap. I want a quality engine, with quality parts, and a proven combination that I can beat on for a while.
I have time, and I have the money to do this. Hoping to have it back in the car sometime next summer if it will take someone that long to build it. I am located in Florida, and I am not scared to ship an engine from somewhere.
I am a mechanic, ASE Master Automotive Certified. I can speak the language, and I have a background in Japanese performance turbo cars. While in the military I owned quite a few of the Nissan Skylines while stationed in Japan.
Please PM me, or email me if interested.
Thanks
Sean
