@Boosted: Did you consider a SS turbine housing for weight savings and corrosion prevention considering the placement of the turbo?

hey Boosted Performance,

we've been manufacturing parts for a longggg time...and from one manufacturer to another...that is absolutely incredible work! keep it up, and please keep posting pictures of those beautiful welds!!

that is very nice for you all to say!

why does the placement matter for this? It wouldn't be the same if the turbo was anywhere else? I'm sure the customer can choose those options if they want to spend the extra coin. My turbo turbines are ceramic coated but I havn't seen any turbos around here suffering from corrosion and we have tons of humidity and salt air.

Bet boosted has this thing at the dyno already LOL!

Can we get them coated before they're shipped out? My Z is always in the garage anyway but still would like to protect this investment as mush as possible

Well, for starters there is no such thing as a SS divided turbine housing...remember, this is a twin scroll turbo system. On top of that, I use Precision turbos and Precision does not offer this as an option, only Garrett turbo does. They also only offer it for the GT35R turbo and the GT42 (a rather large turbo). The heat alone will prevent the housing from rusting, it may develope a bit of surface corrosion but that is as far as it will go.



Thank you. This project is now complete so there probably won't be any more pictures, although I took a lot more than I posted. This thread will be a good source for DIY installs.


The turbo will not be shipped from me. It will come direct from my supplier, along with the fuel pump, UpRev, Intercooler, BOV's, waste gates, and injectors. This saves you guys about $250 as I would have to pay for the items to ship here, and then back across the border. It is also cheaper to do this in the U.S than here.

The only thing that I'm worried about is the demon bolt which I put TP's on so not to worried about that and putting in the fuel pump and injectors

it really isnt that hard to get off, just get some extentions and take your time on it, pb blaster it a few days before you do it and it should come off easy.

Just get your kitty (eavater) to do it.

Injectors are very easy to do, you just make sure to put some clean oil on your finger tip, and lube the rings before sliding them in to the rail, and back on the car. They slip right in there.

The waste gates are recirculated. I was wondering if there will be an open dump pipe option. Or is there a way to simply cap off the hole on the down pipe and leave the waste gates open.

The recirculation will the options, and open dump will be standard. It is a real PITA to recirculate, and it will cost more to do it, hence it being an option.

:icon18:

Boosted will you offer the kit without the fuel pump, injectors, and uprev liscense in a "tuner" kit for people that would rather source there own different components or already have an uprev lisc.?

Yes, there will be a tuner version available for sure.

What is the benefit of running open dump for the waste gates?

Awesome. Man this thread makes me think about taking off and selling my Stillen kit.

Will you have some optional changes?
If someone already has a decent oil cooler and doesn't want the one in the kit, will you subtract the amount from the kit?
Also, if he wants to have different BOVs, such as HKS, will it be possible?

I would like to know this as well?

Well, turbos on many OEM applications are protected by splash plates. I am not worried about the turbo rusting away or anything, merely a curiosity. Plus, the SS hotsides are much lighter, which is nice, particularly where you have pipes supporting part of the turbo's weight. Anyway, based on BP's response, looks like it's not even an option here.

I think there are Tial Sport SS hotsides available for a broader range of Garrett turbos: link

In theory, even less exhaust back-pressure since the exhaust that bypasses the turbo gets vented to atmosphere rather than back into the exhaust system. However, I have to believe that for most street applications, the performance difference is nominal.

To add to the above statements....the open dump gates will be loud...very loud at WOT. If you stay out of boost there is no noise at all because the wastegates are closed. It get's loud as you approach boost spring pressure, and during WOT runs.

The turbo would spool just a tad quicker because a lot of the exhaust is diverted to atmosphere through the wastegates. It does not need to flow to the back with the exhaust that goes through/out the turbine.

Would running them open damage anything? Kinda like a bypass huh?

No, you can't damage anything. It is just a valve, where things go after it does not matter.

Man I'm a noob when it comes to turbo's maybe you can develop a turbo book for dummies and send it with each kit?

saying that makes u loose 5 spots on the waiting list btw!

HA! You wish buddy.

Sasha is there a way to be able to put an elecronically controlled dump on before the wastegates to let off exhaust to spool faster?

Thanks. There was very little benefit that I could see from a few things I read so I thought I would ask the expert. :tiphat:

:driving:

:bowrofl:

I think what you mean is an electronic dump after the wastegate to allow you to vent either to atmosphere or back to the exhaust. Like an electronic exhaust cut-out. If it was before it would just all dump and you wouldn't spool the turbo. Anyway, it just isn't worth the time or trouble. The performance benefit you would see on a street car probably wouldn't even be noticeable, and you get the great disbenefit of incredibly loud exhaust.

Great disbenefit..... Lol awesome vocabulary bro. Seeing as your not always driving around with wastegates open that doesn't really apply. Also, some people like it..... To each their own. Save some money, be a man and run open dumps! Shoot fire, scare people you pass by, it's great fun.

And its called a quick spool valve. Not an electronic cut out.

BOOOM!

does the location of the turbo make the exhaust any louder/quieter?

Jacka$$ I have recircs! Hahaha

^^^

If you want to be like Ronita, get Re-circs. That is all. ;) His car is a daily driver so he opted for re-circulation, although I don't know why....he never gets on it!!

Thanks for your insight, "bro." However, the quick spool valve you linked us to doesn't do what the other poster was talking about. I'm not sure you took the time to read the link, but as described there: "The QSV essentially creates a variable turbine housing A/R size by blocking off one side of a divided turbine housing before boost pressure opens the butterfly valve to allow the full size of the housing's A/R." In other words, it doesn't allow exhaust to flow to atmosphere, like say, an electric cut-out valve does. Further, since your QSV requires "both a divided turbine housing and an UNdivided exhaust manifold," it would not apply to ANY kit currently on the market for the Z, including BP's. Hope I kept the vocab simple enough for you this time. :gtfo2:

Waste of money, and would not fit. These engines are not known for making gobs of torque down low, so boost at 2500rpm would just create strain on the engine and nothing else. A properly sized turbo will get you good spool, and awesome top end, where these engines are designed to make power.

This is not a V8 mustang with a roots blower (positive displacement supercharger) where it makes 400ft/tq at 1200rpm, with a 4800rpm red line.


The turbo will make your current exhaust quieter, as the turbine does act like a muffler. However, when WOT it may be louder due to the extra flow.



As far as all the other stuff...waste gate: either re-circulated or open to atmosphere...there is nothing else to it. Electric cut-outs are made for post turbo applications where the exhaust may be small/restrictive to exhaust flow. IMO not needed at all for the power a stock block can produce safely, with a dual 2.5" exhaust.

how do we make it so we never see certain peoples posts........

The smarter you try to sound the dumber you look! LOL Did you do your research all night? Seeing this is boosted build page I won't take this conversation any further. Bottom line, your a Wikapedia know it all, go get your hands dirty and learn something. Or better yet, keep asking dumb questions about boosted builds which he's been doing for years..... LOL @ GTFO
