That's good you found it.

Did you have a bit of flex pipe between the waste gate and returning back to the exhaust?

No soild stainless steel 304 pipe. Thought it would be fine. Guess not. Might just change it to a screamer pipe. Never worry about it again

Yeah neo heads are good for 22.0 psi but damn if you touch 22.1 all your valves will melt.

nah the neo heads are awesome. much better than the R33 item.

This car has an entirely stock neo engine and 26psi or something:

28psi on high boost.

if it's your tuner and in specific reference to your turbo that's fair enough then... I'd imagine the tiny little rear housing will get pretty hot too...

In any case you are building a 3.0 and it's not my money so boost it till it pops and post vids

Was told that by 999 automotive. If I run 98 don't go past 22psi and if I run e85 then not to go past 26 27psi.

The guys at 999 Automotive don't know shit, not to mention they sell exhaust parts that don't even fit or line up.

What a croc of shit, I've run 24psi on 98RON through my stock as bat shit motor on pretty low timing (7~8 degrees) but was pointless because the manifold was glowing red as EGTs were too high.

yeah lol at set PSI, ok I'll run 22psi on a 70cm turbo from a mine truck, it'll be fine.

I love the neo head as well, simon doesn't like them though as they tend to ping more than the r33 one but they make more down low with a nicer torque curve due to the better VCT

Might be too much power for this thread but:

Neo head is good for 28psi. Or possibly more, This one haven't melt yet.

Running our very first ATR45SAT prototype turbo, externally gated off stock exhaust manifold. Stock standard, Unopened Rb25det Neo engine.

LOL go Stao!

is that your modified manifold or did you switch back to stock?

Thats actually pretty impressive for any 25..........be even more impressive if its a daily driver and lasts.

Still...they all said that 300 was too much for std motors but look at the number of owners doing that and the sky didn't fall.

So 400 is the new 300!!!

    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.
