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!

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
