istory:
03 Bugeye 188K miles. Intake/Exhaust basic tune. Runs/drives fine. Head gaskets finally let go. Last drove it 9/10/16, no codes, no issues, other than leaking HG. Pulled the motor and bought a swap.
Replaced motor with JDM "low mileage" EJ205. Super clean motor. V8 EJ207 big port heads. Zero sports turbo (Essentially a VF30). Dropped JDM motor in, untouched. Using JDM V7 Ecu. Fired right up. Running open downpipe just while I get the car dialed in. Idle is ****ty so I narrow it down to IACV. Looks like it got banged up during shipping.
Replaced IACV, idle solved. Idles great. Fresh fluids. 3/4 tank of 100 Octane fuel to appease the JDM V7 Ecu. Went for a drive, no boost. Not 1psi. Car idles great, sounds great, revs freely at idle and in neutral. Won't build any boost. Per boost gauge, car sits at right around 20 mHg in vacuum, under acceleration it reaches zero and then stays there.
I have not done a proper boost leak test, however I have replaced almost all the hoses and at this point checked them 4, 5, 6 times.
Two codes : P0365 P0390. However they are as a result of me not wiring up AVCS yet. No other codes.
What I've checked so far:
All vac lines I removed and installed during swap.
BPV gasket replaced.
TMIC replaced with STI TMIC, coupler replaced, new clamps, checked Y pipe and all other clamps.
Checked BPV to ensure it's not stuck open, functions as it should.
Checked all wiring to ensure no broken connections or loose wires to put the car in limp mode (although no codes).
Boost pill still in line and all hoses connected to their respective sources.
Intake hose tight and MAF appears clean.
Replaced turbo inlet hose which had a rip.
Wastegate moves back and forth with pliers, C-clip still attached.
Ran hose from WG to compressor housing, bypassing BCS.
Tried a second, different ECU from V7 STI.
Removed turbo today, no shaft play, spins freely, no cracks in WG housing.
Looked down in up-pipe, EGT probe still in place and cat in the up-pipe is intact and undamaged.
After checking and swapping all the parts above, no change. No boost.
Initially I thought a leak, but I am not getting low psi, I am getting none at all.
Thoughts ? What am I missing here, did my motor come with a bad turbo ? :face:
