They are cheap, and nasty, but with a bit of die grinding, and re-machining of the flanges perhaps(they are only linished by the looks of it) they can be a good option for guys on a budget.

I had to modify the wastegate path on one I had here, as it was going to hit the dump, but it all bolted up fine. Messy mig weld on the inside of the merge was a bit... :/

Mine was also pretty good quality with the collector being pretty clean inside, only complaint I've got is, the 4 bolt flange one of the holes is off centre so it makes it hard 2 slide a turbo over the studs or a gasket 4 that matter :(

So after four years about 20 track days and 10 thousand st ks my hyprid has crumbly cracked welds in the collector no one wants to fix it so time to buy  six boost

 

that seems like a good value . $600 for 4 years

twin scroll manifold.. then one day get a better turbo :)

Theres no real gains or point for  twin scroll if not using a twin scroll turbo ??

I would have thrown the manifold through his front window if that happened to me

or weld it to a gearbox and put on the door step.

 

Funnily enough, i contacted hybrid at the start of the week about their low mount manifold, as they're fairly cheap.

I asked about warranty for cracks, re surfacing and warping. They dodged the warranty question but mentioned they have never had a single manifold crack. Send them these pictures. I'm sure it won't be the first ones they've seen though :ninja: 

 

Thanks to dose mang, i am now going to go through havoc performance.

Touch wood - mine has given zero problems over a few years of track only use.  I expect it will stay that way.

Have to check my race diary but about 12 events consisting of practice day then 2 race days for the weekend.  A bit more demanding than a typical half day event offering 4-5 sessions.

However - I did not just unpack and then bolt on.  Spent about 2 hours with die grinder and grit blasted the hand finished result.  Then had it ceramic coated.  It has proven fit for purpose and application at the power level I'm running.

Any of these fabricated manifolds "should" be checked and given some finishing if warranted.  It's a matter of observing due diligence and preparing things for reliability.

I'm certain that there's some far better manifolds out there, simply that the user pays for the prep and finishing.

My ETM 1jz  manifold is perfect.

 

If I ever build another turbo car I'd never use a cheap manifold. I have in the past and found they are aweful.

 

Compare the collector / merge of a good manifold to the ones above and you can see what you pay for.

 

Prep and finish should be done by the manufacturer no matter how cheap the manifold is. 5 minutes with a die grinder might make it look ok. But shit welds will still crack and break off and destroy shit.

    • 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.
