Thread: Help with my turbo options(pics! now)

I would do the GTi-R turbo, and keep it internally gated. Just get a TurboFX divorced wastegate solution.
I'd consider a GTi-R manifold though...

The cracks on the GTi-R turbo seem par for the course. I wouldn't worry about it. I'd still run it.

If you go with a GTi-R manifold, GTi-R turbo and divorced downpipe you'll have a pretty good clone of my setup. ;P

hey quick ? i have a w11 aviner which comes with a bbt25 turbo whats the safest boost level i could turn it up too am thinking 15psi let me know thanks

See forum title. Also -1 for threadjack. The Dash = srs bsns.

take the line off the wastegate and watch your boost gauge going till it blows up then you know whats safe

My biggest issue is the s14 BB looks to be in much better condition and I know that is what the previous owner was intending to use and I already have the manifold, o2 housing and down pipe. Of course the o2 hosing matches the DP and I can modify the one bolt hole that doesn't line up on the housing (o2to turbo).

Meanwhile the Gtir T28 has the cracks and a fair amount of thick black soot on the compressor housing. Would this indicate a blown seal and need for a rebuild?

PS Ben do yo find the screamer to be too loud/obnoxious on the street? (my car will be a Daily). Although I already have a 3" Down Pipe.

thanks for the input.

The cracks are probably not a big deal and the soot is normal as long as it isn't coated in oil. You can do the internal gated gti-r with the screamer also as it is a good option that I forgot about since it is a newer option. Either way it is a great setup. If you are concerned about the condition of the gti-r turbo, don't get rid of the other t28 until you get the gti-r setup and see if it is working properly but I would bet that it is just fine. The external gate setup I recommended because his goal was over 300whp and I think it could be done safer with an external gate if he is going to push it that much. It is proven to make more power than internal but I haven't seen the screamer yet but on DSM's it made more power than a non divorced setup. Until lately we didn't have that option. I think the avenier is a decent flowing manifold and while it isn't quite as good as the gti-r, it is a good option.

Okay thanks for the feedback on the turbos condition. I will look to get the gtir setup to use with the Avenir manifold and o2 housing and the 3' DP I already have. This TurboFX screamer is the one built into their down pipe correct? Im not sure I want to spend the extara $ on a new dp when mine is brand new!

I do agree the screamer/or external wastage are the way to go for 300whp+ but that is a future goal and will req cams etc. For now and prob next 2yrs I am looking for 250whp.

That TurboFX divorced wastegate is sexy!

on a bit of a side note how different ecu tune wise would the gtir t28 be over the avenir t25 I have a tune for?

Thanks again

Black soot is also normal for the GTi-R turbo. Don't ask me why.

If you have everything for the S14 turbo, then go with that one. Upgrade to a divorced setup later when you want to spend a bit more money.

My divorced downpipe is recirculated. No screamer for me. So it's not too obnoxious. =D

The tunes should be very similar as long as you are running the same injectors and maf combo. I don't see a reason that it won't work with your goal of 250whp.... For that I think that you have the perfect plan with what you have. Hell, if the s14 t28 is ball bearing and your setup was designed around that, I may use that setup if I were you. Keep the gti-r for later down the rd and sell the s14/avenier setup and get either the screamer dp of an external gated gti-r manifold. Sounds like the s14 turbo would be slightly more reliable and should spool a little quicker. For your current goal that might be the way I would go. I would have to actually see everything in person or at least in pics to know for sure. If everything that you have was setup to run the s14, I would probably run that knowing more about the situation. Sell the other turbos and save for another setup down the rd. The s14 turbo will make more than 250whp so you still have room to grow and it sounds like it is in better condition. More than likely after 2 years you will want more than a gti-r anyway, lol, so sell which ever turbos you don't use and throw that money into your car fund since things can always come up such as clutches and transmissions breaking. That way you have a fun car and reserve cash for disasters since no matter what you do something will always come up.

Ben- I was typing my post while you posted yours, lol. I think we both agree on this. The more I know about the situation the more the s14 would make sense. You won't have to make any changes so that is a huge plus and since the goal is now 250whp for quite a while, might as well go with a faster spooling, newer & easier to install turbo.
