So i'm sitting here wondering if there is a way for me to seperate the dump mouth of a standard 33gtst turbo to make a seperate gate and dump flow.

I have a split dump pipe and i want to know if i can divide the 2 outlets on the back of my turbo into 2 seperate sections, meaning that when my gate opens it goes straight out but when im just cruising it flows along through the full system.

Let me know if anyone has done this before. Im interested in seeing if/how i can do it.

Cheers

Ben

Most internal gate screamers leak a bit. A piece of metal needs to be added to the turbo side of the exhaust flange to block flow between the waste gate and turbine outlet at the back of the turbo. The trouble with this as far as I am aware is that due to heat expansion, a perfect fit can be problematic. Also, when they are mass produced, differences in casting make it difficult to have a decent seal as one turbo may be 0.5mm smaller than another meaning to seal up on the larger, the smaller would not fit.

Other than that, cut the waste gate pipe off the dump and seal up the hole. The waste gate pipe can then be cut further and routed off to where ever you want it.

Make sense?

Like a dual port blow off valve type setup? A vent to atmosphere and a plumb back waste gate?

Nope, a screamer is just a pipe that goes atmo from the wastegate... Internals generally don't sound that nice, have issues with leaking (as mentioned) and due to smallish standard turbos would be open a LOT..... I have mates with them but would never do it to my own car.... There is a few different designs around and yes you can do it....

So the stepbrother bought a 32gtst. basically stock with a fmic and 3 inch dump back system. Internal gate screamer fitted and it sounds brilliant. Well worth the cash in my opnion. Although when you see a stock xr6 out accelerate a skyline when the skyline sounds like its got 250rwkw its pretty funny. Not a bad investment guys. If you want that epic gate noise from your car.

They sounds average at best, Once you hear a proper external you will know the difference :P

Looked at one of these for my 32 race car where defect is not a problem. But yes even my race car with only around 200kw would look funny getting smashed by a quieter 33 or something on the track lol.

This haha.

Internal gate screamers sound like ARE an exhaust leak.

FYP

Although all screamers are, it just sounds more degrading that way :P

Alot of people who can't afford the whole external gate setup would like it though. ill see if i can get a vid of it so yous can hear it.

Link Vid!

    • Ok glad you clarified on the frenchy’s options , I was worried about if my oem hoses would fit the new compressor or not if I just bought the bracket/compressor kit ,  didn’t realize they also sold a larger full conversion kit. Hmm may just go oem in that case then to make it easy only because I plan to sell this car to upgrade to a 32 GTR or 34 GTT.
    • Right, here's a video of the basic operation at least.  This is what you can expect day to day when you turn the car on and it boots from standby.  The only thing from a media point of view I haven't gotten working is for it to autoplay plexamp when it turns on from standby (it works from cold boot) but that's more of a plexamp problem as it will autoplay other music players.  Also attached is my one stray cable.  It's part of the screen's wiring adapters but there's just nowhere for it to go in my car.  I've just now done a bit of research and found a matching port on a 2010-2014 head unit with BOSE.  Mine has no BOSE so that's that case pretty much closed I think.  Plugging in the Infiniti AC panel basically did nothing for me, so that's a dead end as well.  Next port of call is to mess with this CANBUS module and see what I can find from it.  I found this resource containing the DBC files for a 2010+ G37 : https://github.com/icecube45/Dash_InfinitiG37/blob/master/InfinitiG37.dbc I'll now have something to go from when I try to extract my CANBUS data so I can see if the HVAC Mode, Fan Speed, Temperature, etc. match and also the gear shifter position.  It's a pretty big assumption that it's just mismatched CAN signals but considering all the devices in the CAN network are talking to each other (AC can be fully adjusted just with no info on screen) it might be a safe one.  I will report back WhatsApp Video 2025-02-26 at 12.49.10.mp4
    • Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went? 
    • Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was £307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell. 
    • As above, you did refill the coolant and burp the system before running it again didn't you?
