so i installed the valve springs on my motor....simple process, just time consuming. Also went ahead and installed the L and R aero panels with simple self tapping screws. Im waiting on some hardware for the muffler panel and will get that installed asap as well. I wasnt able to secure the pane in a couple of spots because the panel holes were up against the actual floor pan and not a hollow crossmember like most of them were. So the plan is to get some "adhesive or weld mount studs" and stick them on the underside with epoxy to hold up the couple of spots i couldnt drill at. The muffler panel might be trickier since the Verano and Eco use what appears to be a different tank strap that has a stud on it for the panel to fasten to. I might have to just zip tie it or put another weld mount on the heat shield.

Dyno pulls are scheduled for later this week to get baseline numbers before the GTX250 is installed. I am fully prepared to go all out with the new turbo, cant wait.

GTX250 is in and 350 miles into its break in process. I took a 5hr trip last night and averaged 24mpg on E80 @ 70-75mph with nasty side wind all the way. Boost does take longer to kick in but when it does, it just keeps pulling and pulling and pulling. The car put down 160hp on a hot/humid day with a low reading Dynapack and what looks like an above average crack on the turbo....would explain why Jerry was seeing pressure drop where it shouldn't.

Hopefully I can coordinate Jerry with the dyno shop so we do some "live" tuning while I'm there and get you guys some solid numbers from this turbo. Not much else to report other than just taking it easy on it and waiting to get it dialed in

Got the third aero panel on, but it looks like the eco cruze and verano both use a different set of tank straps with provisions to bolt up the middle section of the panel

283096


My 2LT doesn't have those flat surfaces to the aero panel to bolt or clip onto. So as seen below, I just used the outer mounting brackets and then just ziptied the middle portion which has 2 pre-drilled holes (I assume for drainage purposes?) up to the gas tank shield (#5 in the above parts diagram).

Heres a pic of the aero panels on the verano they came off of,


you can see how the tank straps have provisions for the plastic nuts....non-aero package cruze don't have that.

Right panel on the donor vehicle


Left panel


And DEI gold tape on the underside of the oem heat shield. I also header wrapped the downpipe and hot side of the FMIC pipes (Not pictured).

76,600 miles now (3k on GTX250 setup) and the felpro valve cover gasket I used when I did the spring swap gave out under boost. I guess it was pushed out of the cover and was causing a massive leak...had -30 LTFT at one point. Will probably just pick up a new cover and keep this one as a spare. Might have to crank down a lil harder on the valve cover bolts too, 28psi seems to be too much for these gaskets.

did you need to change anything on your fuel setup ? besides injectors, did you need to do fuel pump of even the fuel pump module BNR sells ?

running BNR 60lb injectors along with their FPCM. Stock pump provides enough flow and psi to the injectors, even on full E85. Car is at 83k now, no problems, zero complaints and oem valve cover gasket has been holding up good with 9.5-10 AFR at WOT all the way to 6k rpm.

If youre considering the GTX, do it...I love it...its the best thing ive done to the car. You wont need the pump module if you dont run E85 and you get the 60lb injectors, which I recommend over the 42 or 52. The 60s perform better at idle and low engine speeds than the rest.

Thanks, i bit the bullet last year on the ZZP V2 turbo, this was before BNR released their new GTX. long story short it only went in the car a couple weeks ago and i have the car parked for another month or so so i haven't even been able to take it out. i do already have 42lbs injectors, but was curious if i had to go the next step with the pump and stuff.

been seriously contemplating getting the bigger injectors and their FPMC though.

cheers

Got my 60lb tune in and its way smoother than the 52...especially at idle. I bought a spare 1.4 longblock for $100...plan is to rebuild it it BNR pistons and swap it in when ready. Had to order the kent moore valve spring compressor because the little hand held one I tried doesn't fit inside the spring holes....though about buying a universal one but I don't think I can keep the spring compressed with one and and install the locks with another..thats not an issue with the KM tool design. Since I'm removing the springs, will replace valve stem seals as well, so ordered the KM seal puller and the installer tools.
