USMCFieldMP's Turbo Build Thread
The OTTP TB Spacer that I ordered on the 6th STILL hasn't shown up... that's the ONLY thing I'm waiting on. That's the ONLY reason we didn't get it started on Tuesday. Now I have to schedule a different time for my Tuner to come up and tune my car.
I better get to drive this ******* thing before I deploy!
If the OTTP Spacer isn't here tomorrow... I'm driving to ZZP and picking one up, so that I can put it on and start it tomorrow.

Yeah... IF I can get a tuner. I'm having a hell of a time. Wicked usually tunes me... but he's working a lot and can't take the time after work to come tune me.

Got everything together and started it up. Goes straight into Limp Mode because the factory boost controller was removed.
I'm also having a HELL of a time with the 2.2L Belt Tensioner... I don't seem to know how it works properly, I guess. It doesn't seem to move... where ever I bolt it down is where it sits.

Indeed. I'm trying to coax Tom into making the trip to tune it.
Car should be hitting the road in about an hour an a half.
In typical fashion... we had many problems.
First... it kept going starting in Limp Mode... eventually we figured out that the LS4 TB was bad... the butterfly just wouldn't move.
Second... the belt squealed like a mother ******. We figured out that it was the belt rubbing on the bottom of where the old tensioner bolted on. I quickly removed the Alt, Alt Bracket, took an angle grinder to it... put it all back together.
Third... belt still squealing. The 2.2 Tensioner was at an angle causing it to jump to be on the outer most teeth of the A/C, but the inner most teeth of the Crank. We sort of fixed that... somehow.
Fourth... I have a vacuum leak. I don't think its the piping... because I still hit boost and it holds that boost well. I think its on the Manifold somewhere... but we can't be sure tonight. I don't need cruise control... I just have to take my foot off of the gas and it'll maintain MPH. When I push in the clutch... RPM's rise a little and then hang. When the vehicle comes to a stop... they'll hang a little bit, then finally drop down. It used to idle real blotchy and it was throwing a "Supercharger Inlet Pressure Sensor Low Performance" Code... so I swapped out that vacuum hose. Haven't deleted the code yet to see if it went away yet though... the idle doesn't bounce around anymore though. It still rev hangs like a mother ******.
FIFTH... Oil Leak. Either where the Oil Return connects to the Turbo... or at the pan. I think its on the turbo. I dunno, gonna jack up the car tomorrow to find out.

First pull. 20* Timing, Car hit 8psi. Not that fast... but it moved out. Stopped, turned fun knob 2 full turns.
Second pull. 20* Timing, Car hit 10psi. It moved out this time, quite well. IDC's at 60%, IIRC. That's when we got it back to the garage and noticed the Oil Leak. Threw two quarts in it, turned the fun knob some more, and drove home for the night. Tom left, thank ya much.
I couldn't resist myself on the way home... Brake Boosted in 2nd gear @ 40mph... car RIPPED... broke the tires loose when it full boost (IDK when that is, so don't ask! Haha, I'm too used to the VW so I'm staring at the road). Car hit 15psi and just ROLLED OUT. Broke up a little bit up top. Got it home... popped the hood because the battery light came on. Belts gone. Turn the Fun Knob DOWN one turn.
Gotta figure some **** out tomorrow. It'll be a long ass day.

Got most everything figured out.
I haven't found the vacuum leak yet... and I'm pretty sure that it is post-TB... and its causing the HKS to screw up and Compressor Surge. Sounds Cool. Does Harm.

Put a much smaller, tight as hell vacuum line on the BOV... still chatters.
Think I found the vacuum leak... seem to be coming from where the I/M meets the head.

Yo Rob! I was ******* PUMPED all day. One lil sugar free rockstar, got to my job, and I was MOVING! A friend asked if I was high, said "not that I know of". Best day ever in a while. Full of energy, great mood, went to bed last night at 2am. 
As for the car....
sorry to hear the troubles. Wish I knew turbos better. I was pretty happy tho when you turned it up to 10psi. That was a fun/scary pull. You need to relearn about trq steer

Oh, and I saw Jeff Dunham at the Nutter Center last night. ******* HILARIOUS! I love that guy and finally got to see him in person. He trialed some new lines last night that were A M A Z I N G

Bought and installed a Tial BOV.
-Compressor Surge is gone.
-Idle AFR dropped to low-mid 14's.
-And the car now pulls like an even harder raped ape.
Hopefully the non-opening HKS didn't **** up the turbo. Don't want something to break just yet, need this car this coming week. Haven't really taken it past 5 or 6k in 3rd. Next weekend is my last with the car... I will be pushing it to the limit... and probably on 15psi... not 12psi like I am now.

No... I don't think the BOV was VENTING.
It still Rev Hangs a little... so I might still have a tiny tiny leak somewhere. I'll search it out later though.
