1.10 a/r? That is neither a T3 or a T4 option from turbonetics. So, when these units are bolted up in their natural use (i.e. truck/tractor), what turbine housing do they usually come with? Closest option is a T4 tangential/divided housing with a 1.15 a/r. That would be one hell of a hot side that's mated to a dinky little cold side.

And I don't feel like reading through 39 pages to find out what turbine wheel this turbo comes with.

I went and checked and it the stock turbine housing off the Vtrim is the T4 1.15 a/r. What you have to remember is that those big turbine housings are used in diesel applications that have high exhaust energy unlike gas motors. So they need that larger A/r housings.

The turbine must be the same that have been on my AGP turbo's which have both had the T-31 wheel/stage 3. I have my new RS60T here not yet installed and can get some figures, might even have the inducer/exducer numbers here somewhere. Mark

Does anyone know the thread size of the oil inlet on this CHRA??

 

[1029TSG]

1/4" Npt

 

[sweet97]

Well Bullseye sent me the turbo to 02 housing gasket and did not charge for shipping and they used a postal service mailer for $1.08 instead of the $8+ ups charge for the first gasket I got. Thanks. Now I need the little gasket that goes between the turbo and oil return, what to do??? Mark

Use RTV.

 

[1029TSG]

RTV = smokin turbo. When you tighten down the flange it squeezes the RTV into the oil drain and restircts the flow. Make your own paper gasket or order one from www.theturbotrader.com

 

[sweet97]

The turbotrader looks like Bullseye's little sister! I had to ask how a $1. item would be sent!! Mark

Yeah, most parts stores and hardware stores sell the sheets of "make your own gasket". It like thin compressed tagboard..... It worked well when I had my 14b and it's only a couple bucks.

 

[whitegst97]

Sweet i have an extra one, if you want i could send it to you, i'll put it in a regular letter envelope. Or go to your local autoparts and get some gasket paper and make it.

 

[1029TSG]

Yeah, they buy from us and we buy the oil lines from them. They can ship USPS as well. I still think it would be better overall to make one like 99gst said.

 

[99gst_racer]

David - Would a 3AN oil feed line supply enough oil to these turbos? I found a restrictor that is .078 but I would need to run a 3AN line. What do you think?

 

[1029TSG]

We have never used, tested or sold -3 oil lines. However, I've been told they can be used in lengths of 24 inches or less. I'm not even sure you would even need a restrictor with a -3 line.

 

[sweet97]

Ben at AGP said high oil pressure doe not hurt seals. All just a myth. He went on to say that there was no "seal" to blow but a ring at the end of a shaft.
Hey Miami, I'd rather pick up that gasket in person, I'd like to get out of Syracuse area anyways!! Thanks, Mark
PS: I'll send the flange and a dozen sheets of gasket paper to a local kindergarten, probably o better than me!

Quick update on where I am with my Vtrim turbo:

Got most of the leaks fixed, still a pinhole somewhere in the IC piping. The car is tuned for street manners and mild boost so far. Finding and fixing problems as I dig in to this deper. Things like spark blowout, fuel/air ratios, etc. I am working on the higher RPMs now.

Spool-up is now 10 PSI at 3000 and 14 PSI at 3400. I have the comp outlet routed back into the wastegate actuator for now = 14 PSI max boost. So 14 PSI is the minimum boost on HP actuator when it is tightened 2 turns past closing the wastegate. Based on what I've seen, 28 PSI would be the max boost on this actuator.

At 6000 RPM (14 PSI) I have already acheived ~ 28 lb/min. This was with the mix going way lean and I had to let off. The car was pulling very hard. The turbo was barely working up a spool. However, it did sound sweet.

So, I am feeling pretty good about what's happening and I am confident that I can get to 350 HP in a couple days now.

Cool, I should be getting mine tommorrow. Dave is very helpful in helping deciding what's best for a given setup.

I have a custom ported 95 O2 housing to match the 2.5" opening on my 3" downpipe, and the opening of my old Evo 16g. Would upgrading to a 2.5" custom tubular o2 (i.e. Punishment) net me any gains, or would it be minimal? I'd rather spend the $150 on helping me get the FP2's or HK$'s sooner. Anyway, I'm excited to get mine as well, and will be doing a picture write up/install.

i just finished my water injection, just gotta find a place that sells methanol now,

 

[CarSalesman]

I am finally getting enough parts on my 97 GST Spyder to beging to get it dialed in. I really do like the T04B I bought from Dave and as in previous posts he was also great in giving me advice on the what went with what.

To date I have installed

K&N FIPK
Injen intake
T04B internal wastegate
Injen Hi Low MBC
650 injectors
255 HP Walpro
S AFC II
(waiting on a 3" turbo back exhaust from R n R Racing)

Driving it now with the stock exhaust this turbo pulls very strong and I have some modified SRT 4s here at my disposal to compare it to. Tuning at this point is next to impossible so I am running it really rich and by some instuctions off the roadraceengineering web site. If what I am experiencing now is just the tip of the iceberg (pre exhaust) I have to bullseye for having an impressive turbo. I have found a dyno to tune to once I get the exhaust and I will submit the results to Dave and to this group as well. Heck, at this rate I may get froggy and start doing some internal mods ...

Cant you just use windshield washer fluid. I thought it was 50% water, 49% methanol, and 1% blue color..... I could be wrong though.....

 

[99gst_racer]

Just in case anyone is interested.... I got bored yesterday and made a oil feed line restrictor for the T04b.... Check out my write up.
