Quote: If your application requires a twin scroll T04 flange, then you're in luck: the twin scroll T04 housing bypasses gasses from both scrolls making this the first aftermarket performance and racing turbocharger to offer a twin scroll internally wastegated turbine housing.

Mmm, nice.

Mitsubishi have had internal waste gate twin scroll turbos since the Evo 4.

Nothing new, but still cool.

I will have the catalogue in my hand probably tuesday. We will make my next turbo selection from there.

I've pretty much made up my mind these borg warner's are where i want to go.

??

BTW, the EFR turbos are at the higher end of the aftermarket turbocharger price spectrum. The reason why is because they are so feature rich........ If you look for quality and don't mind spending a premium then keep reading.

Taken from one of the links... I guess BW turbos had there stint as being very well priced in comparison with Garrett.

Friend will be back on deck from sema on tuesday and will hopefully have all the relevant guff we need to make the selection we need.

That and I'm an old prick. would rather have a paper catalogue than the link you posted that wont open for me anyhoos. :ermm:

There are some prices in the link I posted earlier. 2.7k US for the external wg 8374... so over 3k landed. Hopefully these are only preliminary numbers...

nasty pricing

surley they would stick it to garrett by matching prices initially

ill definately be holding off if they cost that much, untill they are proven to be the shit by one of you guys

So nearly $3k for turbo, plus Full-race manifold $2.5k (landed), twin wastegates $300ea; you are over $6k and you have no gaskets, dump pipes, intake pipes... Halve that at $3k and a set of -5's would be fine thanks!

And you get the gaskets lol

is you'll find that the Series EFR turbos are unlikely to directly retrofit into existing T25/28, T3/T4, or GT30/35/40/42 fitments

Indeed a very costly exercise to become a guinea pig!

The BOV placement is interesting, in a space conscious bay, that could be a bit of a problem.

Another possible drawback is that the turbine housings are not available in various A/R sizes due to specific gas flow optimization for the housing and wheel shapes. It is possible that BW may release other A/Rs in the future, but for now the T25 inlet wastegated housing is only available in 0.68a/r, the T3 open volute (single entry) wastegated housing is only available in 0.85a/r, the T4 divided (twin scroll) wastegated housing is only available in 0.95a/r, and the T4 divided (twin scroll) non-wastegated housing is only available in 1.05a/r.

Interesting...

Like the idea of moving the mount points thought, nice and easy.

Well the Sierra Sierra EVO has knocked 2 seconds off its personal best (which happens to have been the lap record for the track, which it took off HKS) at Buttonwillow on the first day of US Superlap using an EFR8374, gotta be promising...

so probably no twin option for a standard capacity GTR hey... if GT-RS size is the smallest they're going... if they have that size that spools like the old 2530s then I'll take 2 thanks;)

they are testing twin turbo IWG applications at the moment on a couple of GTRs. I have some pics but not sure if I can share them yet, but set-up looks good. all that remains to be seen is results. ;)

    • I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.
    • @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation. 
    • 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.
