Chasing That Stock Sound

[TTT]

stock bov goes to the very far left pipe in this pic..

That image is a stock R32/R33 GTST intake pipe with all the EGR and BOV return pipes intact.

I assume yours is still there and just blocked off.

Not EGR. Crankcase ventilation.

An I better of having a new dump and plumbed pipe made? Or bought whatever's easier?

I prefer to have things done properly myself, I don't know much about the pipe work but gauging the last reactions I dont want something "falling off"

[GTSBoy]

The problem you have is that you have a TDO5. So there are no off the shelf dumps available (or, at least, if there are they're nowhere near as common and easy to get hold of as for Hitachi turbos). Which means that you're looking at a custom dump, which just makes it that bit more expensive to get done than buying a cheapy from JJR etc.

My main complaint about the dump and screamer that you have is that the design is woeful (sharp elbow changes of direction, poor welding, what the hel is going on with that screamer just poked in the exhaust housing with no apparent fasteners!!??!!) and will negatively impact on how well the turbo works (will raise boost threshold and reduce total power by some amounts). Nicer dumps are nicer. Plus there is the risk that that screamer might fall out, depending on exactly how it is held in there!

he's making 210rwkw.

by paying to have it plumbed in to the existing exhaust he won't lose too much if any power at all...

espcially if he is only running 1 bar of boost.

agreed though.. it looks really badly put together.

[GH05T]

I will quiry an exhaust place but what sonyou think is a fair price for a custom made dump and outlet do ya think?

[GH05T]

Actually I gues it's just that pipe that needs remaking properly and plumbing into the dump?

Also for now I assume, aslong as it dosnt leak at the outlet, that welding it into the dump will even be enought to make sure it dosnt move anywhere or come away from the turbo, atleast it will be legal for the time being

I think the best way would be to buy a bellmouth dump pipe and fit it yourself. Done and done.

1. It will work

2. Split dump pipes still have that whoosh whoosh sounds with stock turbos that sounds hella ghey - bellmouth do not. Also bellmouth do not have the potential boost control issues inherent to the split dump design.

[GH05T]

Ah sorry so a bellmouth covers both, just picked that up.

Being a td05 is it still going to be a custom job?

[GTSBoy]

Yeah, well that's the point I made earlier. Off the shelf !exist (probably).

[GH05T]

Time to hit up a shop to make one. What should it cost and should it be stainless or will mild steel be all that's required

[GH05T]

Theirs no point I. Making a new topic.

What can ya tell me about the TD05 turbo? Is it a good choice is it a bottom or top end turbo anything I should know or a thread I should be reading?

[XKLABA]

the outlet flange on that turbo is not T25 so finding a flange to bolt to the turbo is going to be the hardest part, you need to find out what bolt pattern it is and have dump pipe made

the waste gate pipe that is there now is leaking, you can tell by the soot around the pipe, and that is with no back pressure as it is a screamer, so if you just weld it into the exhaust that leak will only get worse unless you find a way of sealing it properly

[GH05T]

Well I'm out of my depth, who do I talk to?

[GTSBoy]

Brenton at Fours'n'more. Can make any dump for anything.

Another thing you could do is rip off the TD05, sell it, replace it with a high flowed factory turbo, then use an off the shelf dump pipe, put a stock intake pipe, BOV return pipe and crankcase ventilation setup on, get it tuned again (You were talking about getting your tune looked at once you had fixed the miss fire anyway) and there ya go.

Now sounds like a lot of work, and well it is. However, it will erase the getting defected for an after market turbo part completely as you cannot tell a high flow turbo from just looking at it. And if you do ever get defected to regency for what ever reason, they wont even know you have a high flowed turbo either. However they are smart enough to pick up on the Z32 AFM, but all you simply do is remove the sticker.

That dump/screamer pipe is shocking aswell.

Just another option

It must be internally welded. There is nothing wrong with the td05 tho a td06 would be better is it kando branded? The if you wanted everything re made it will cost a few hundred the dump should be a 3 bolt flange. I would get the screemer cut where that angle is and put a flange there then weld the pipe to the housing that way its sealed and removable then get the screemer plumbed in from that flange back. Don't go stainless makes no difference and ends up looking like mild steel after a good serving also can hurt the pocket.

Cool thanks for the advice. Will chat to Brenton. New turbo sounds like new money than I wanna spend atm, didn't even realise that a new turbo was a defect, how bout that
