It wasn't an option to pull the engine, as it likes to come out the bottom. You gotta remove the upper engine mount and support the engine to remove the crap from the front cover. Otherwise it was a dream to work on.you rebuilt your engine with it still in the engine bay?
Yes i was having trouble with 0.75 and the water/methanol it would give me a heavy spark blow out. So i leaned out the tune slightly to compensate. I will be going back to a rich tune when i address my lack of fuel delivery and install the BNR coil pack upgrade.I see your signature shows 12:1 AFR (0.81 Lambda), seems lean from what I have seen. Do you get significant gains over running 0.75-0.78?
Actually im looking for help in that department, i wanted to go higher pressure fuel pump instead of #52 or #60 EV14So, how are you addressing the limitations of the stock fuel pump?
One of our mods over on the Facebook side is running a BNR GTX turbo, forged pistons, stiffer valve springs, and e85. He's capped at 220whp because the fuel pump can't keep up. I believe a few people are experimenting with a plug n play fuel pump from a different application, may have been the ATS? I don't remember exactly, but long story short, I have no solution, and I was hoping you would, since the community could sure use one. With those reworked turbos, these cars are easily capable of 250whp, but we can't supply the fuel to do it.Actually im looking for help in that department, i wanted to go higher pressure fuel pump instead of #52 or #60 EV14
If i've seen a few modded pumps to fit in the cruze tank, but im still holding out for a plug and play one.
Any recommendations?
Also need a tune that can accurately meter air over 22/lb min to break my 220hp limit. I can throw $1500 at it and get a typhoon intake , bigger injectors and EFI live tune, but i'm looking to use HP tuners + upgraded fuel pump + stock diameter intake for accurate MAF readings to get over 220 WHP.
My first thought was that it might be possible that the stock PCV system tubing is completely inadequate at high boost when running the probably slightly looser forged pistons that the turbo drain line can't drain as quickly as it needs to because of positive pressure in the crankcase. We saw this happen on old, tired Volvo engines running bigger turbos. Solution was to put a larger diameter PCV pipe and hose fitting (very small diameter at the turbo intake for some reason) on the inlet side of the turbo.Ran some seafoam spary through the intake track, loosened up the oil and cleared it out. Cleaned some tubing by hand and tired it again, its is now apparent that im losing oil on the compressor side of the turbo (turbonetics 11038 ball bearing)
Its losing about a cup every 1000 miles which is pretty annoying. I just ordered an oil pressure gauge and am going to check crank case pressures and oil pressures. Considering how im leaking i figure it would be to much oil drian back pressure or to much pressure feeding into the turbo.
Inspecting the turbo by hand i cant see any play in the shaft or anything else funky. If my pressures are all normal i'll get the turbo rebuilt.
Can confirm oil is from turbo, catch can and pcv system are functioning normally and as expected. Getting an oz of oil every 1000 miles in the catch can.
Think your right about the stock pcv being restricting... All the evidence is there for high crank pressure, leaking were it shouldn't n allMy first thought was that it might be possible that the stock PCV system tubing is completely inadequate at high boost when running the probably slightly looser forged pistons that the turbo drain line can't drain as quickly as it needs to because of positive pressure in the crankcase.

Hand built by Howie @ HE Performance. It looks like he cuts the exhaust flange himself with a CNC Plasma cutter, and uses sch 80 pipe steel, and connects it to a pre-made T3 flange.Can you share how you build the exhaust header to bolt to the larger turbo?
