Why don't you have Brembos? Did i miss something
You're still alive! Oh god this thread has me all sweaty and stuff.
And yes, where are your Brembos?
well get a response by Christmas, lol jk.... This build got me all hot n bothered
Who are you having tune it? Hptuners or Trifecta?
should be fine i only have 15 messages... 😕your inbox is full when i've tried sending you a PM
Different transmission than the Cobalt.How did you make 380 through an auto with a ZFR? Most people barely crack 350 on the cobalt forums. They don't make power! Buy a werkz WR-3! EFR turbochargers are always 2nd rate to a GTX

It's coupled with a forged engine so that has a lot to do with it. The efr is very well suited for 400 on pump and 450 on E... If I had to take an educate guess i would assume he went EFR due to the spool time--- not much of a difference but with auto it may have been an important factor. Another reason the efr can make power for the smaller wheel size is that it can efficiently spin at a significantly higher rpm that most aftermarket turbos due to the titanium aluminide exhaust wheel.
" We have the advantage of direct injection raising hp at the same airflow. E85 also throws those numbers off a decent amount further. "
The WR-3 is making right around the same power as an EFR/ZFR--- they are both great options.... and options at that-- I used to work for precision so i'm familiar with with the wr-3, and they aren't cheap, even if they started using chinese wheels.
well i missed your Christmas prediction, but hpfpupgrade.com called (on cmas eve) and my shiny new HPFP (high pressure fuel pump) is here; should be good for 600WHP+
i'll keep you guys posted: so far the car is still running strong and the forged engine build is still holding at ~470WHP
Trifecta all the way. Custom operating systems and aftermarket high pressure fuel pump support is why.
If you'd like to try out a Trifecta tune / custom operating system I'm sure thats something that I can look into.

who says i don't have some OS giken going into the car right after i have raybestos clutch packs installed after backcutting the carrier and shoving in a full two more friction plates in there? (auto trans)
some bridges are going to have to be crossed when we get to them, but thats another thread and PM material, as the purpose of this thread was meant to tell everyone that yes, a ZFR fits and has tuning support, RIGHT NOW

some mods and clearancing is necessary:
on the blue part the heat shielding needs to be cut,
on the green part this air line is just completely different than what came on the stock/OE turbo
and on the orange part, the oil line needs to be modified (lengthened)
the other orange part shows the minimum clearance between the turbo and an AC line, which is about a half inch or so away from the side of the turbo?
yes, its an automatic
the OE (E85) fuel system in the LHU/LDK/etc engines are going to have more capacity if only marginally more than the LNF, of which there are plenty of examples running at ~400whp without either a fifth injector or a ZZP camshaft fuel pump lobe upgrade, so yes, it'll probably be a limiting factor eventually, but not more so than either the auto trans or FWD in this case
if the OE (E85) fuel system fails, then the ZZP camshafts with the larger fuel pump lobes are going in (sitting on a shelf waiting - would like to avoid installing them as it'll affect emissions and idle quality though), and if that fails, then a 5th injector setup is next, and if that altogether fails, then i'm going to machine the cylinder head and weld on a flange and expand the bore of the DI fuel pump to accept a DI pump and lifter out of an LFX engine and if that fails i'll remachine the heads and stick two of them on there, at opposing directions (one will sit off of where the valve cover currently is) and then machine billet stock and gun drill for the DI fuel lines
and if that fails i'll wire in a piggyback fuel solution based off of RPM (window switch most likely) and if that fails i'll swap to standalone with a full set of external port injectors and if that fails then i'll torch the car and claim the insurance money and then buy a V8, pretend none of this stuff ever happened and then get years of therapy to make the nightmares stop
the block still has sleeves, but just really thin sleeves:

i don't think i've yet come across someone basing their shortblock build on an LHU/LDK block yet (no comparison material available), so that may be part of how the block is different?
the block pictured is the one out of the car
i'll send you a PM or we can go into further detail in another thread - but yes, i have a dyno graph of stock vs tuned
